Updated with a few more regular bugs 9th November.

Lightroom 3 beta’s been out for a week now, and the main beta forum alone has seen nearly 3000 posts already.  So, a quick run down of the most popular themes and bugs…

• No PPC, No Tiger – yes, you read that correctly, minimum system specs for Mac are Intel processor and 10.5.6 or newer.  The subject has been beaten to death now.
• Soft Proofing is not in LR3 beta.  LR3 is not feature complete.  Jeff Schewe has been dropping heavy hints, but no one can say what will or will not be in the final release.
• Lens correction – no, it’s not in, and yes it would be very nice.  It’s a big job that needs to be done properly.  You’ve been heard.
• Great feedback on the new image quality – the updated noise reduction is getting some really productive feedback.

Most popular bugs being reported:

• Lightroom won’t install on PPC…. it’s not meant to!
• Import dialog hangs when it comes across a video file.  Solution for now is to exclude video files by unchecking them in the import dialog – they’re easily spotted as they have grey thumbnails.
• Import dialog hangs when you rename with a Total# or Image# token.  Solution for now is to use other renaming tokens, or rename after import.
• Import dialog hangs on big imports.  Solution for now is to do smaller imports!  It’s a major overhaul so will be buggy at the moment.
• Renaming a selected folder makes the photos disappear – restart to show them again.
• Deleting off a network drive doesn’t always work.
• Loupe view isn’t refreshing properly on secondary display.
• Luminance slider doesn’t work – it’s disabled for the beta while they continue working, but will be back in the final release.
• History panel selection has a mind of its own.
• Slideshow turns some portrait photos the wrong way round.
• Watermark – some characters go missing.
• Capture date/time is showing the wrong date.
• …and plenty more besides!

Finally, a gentle reminder that the beta forum is for discussing the new tools and bugs found in LR3.  If you have general Lightroom feature requests, they’re better off in the feature request forum so they don’t get lost in the beta noise.

Have fun testing!

Adobe have just announced the release of Adobe Lightroom 3.0 Public Beta!

Here’s the official announcement: http://blogs.adobe.com/lightroomjournal/

And the download link, of course! http://labs.adobe.com/technologies/lightroom3/

So what’s new so far…?

Image Quality

One of the primary improvements in 3.0 beta is image quality. Lightroom’s been taken back to its bare bones and the raw processing engine has been given a complete overhaul. Even the demosaic algorithms have been substantially improved to give a cleaner file which will respond better to subsequent noise reduction and sharpening.

Performance

While Lightroom was back on the drawing board, the underlying architecture has been completely reworked to improve the performance, particularly with large catalogs. It’s still in early stages at the moment, but the basis is there for a great final release.

The preview system has also been redeveloped, so the thumbnail grid won’t keep going fuzzy as you scroll!

Import

• Entirely new Import dialog, with compact and expanded views, depending on the level of control you need.
• It has panels like the main modules, including Source and Destination.
• Destination folders that will be created by the import as shown in italics so you can see exactly what will happen.
• Import presets can now be saved and reused in both compact and expanded views.
• There’s a new Loupe view within the Import dialog for viewing embedded previews.
• The import backup now backs up with the new filenames if you’re renaming while importing.
• CMYK files can now be imported, although all editing and output will still be RGB.
• If you right-click on a folder in Library module, there’s an ‘Import into this Folder’ option which opens the Import dialog and automatically sets the Destination folder.

Library Module

• Publish Services
  • Publish Services provides integration with photo sharing websites, keeping them up to date with the changes you make in your Lightroom catalog.
  • Sync runs 2-way, so comments made on your Flickr account appear back in Lightroom.
  • Flickr is the first to be available and more are sure to follow.
  • Sync to hard drive is also available, and useful for syncing photos to your iPhone, screensaver, other networked computers, etc.
• Filters are no longer sticky – they reset as you switch folders unless you click the padlock icon on the Filter bar.
• There’s a new badge on the thumbnails showing photos that are in a standard or Publish collection.

Develop Module

• Process Version
  
  • Because so much work has been done on the base ACR engine, a ‘process version’ has been introduced to differentiate between the old process and new processes.
  • Any images with existing settings will be set to the old process version to get an almost identical rendering as previous versions. Any new images imported into 3.0 beta will be assigned the new process version.
  • There’s a warning triangle in the histogram if an image is on the old process version – click it if you want to update (also found under Tools menu).
  • Need to update to the new process version in order to use the new noise reduction, grain and vignette tools.
  • 3.0 beta will not be fully compatible with any ACR version at this point in time. Rendering may vary depending on the settings used – vignette and noise reduction would render very differently using ACR 5.5 and LR 3.0 beta.
• Noise Reduction & Sharpening
  • Lots of work has been done on improving the noise reduction without losing fine detail.
  • Color noise reduction is already vastly improved.
  • Luminance noise reduction (new process) is disabled for the beta but will be back in the final release.
  • There’s a new Edge Detail slider which refines the edges on extremely noisy images at very high ISO.
  • Any old settings updated to the new process version will probably be too strong.
  • There have also been subtle changes to the capture sharpening.
  • The preview now shows sharpening & noise reduction at less than 1:1 view when using the new process version, although it still needs a little work.

• Grain
  • Film-style grain sliders added give a very natural looking grain.
  • It shares a new Effects panel with Post-Crop Vignette.

• Post-Crop Vignette
  • New more natural vignette instead of just painting white or black on the edges.
  • Color Priority mode retains more natural colours under the vignette with softer shadow transitions.
  • Highlight Priority remains heavily saturated under the vignette.
  • Contrast slider brightens the highlights under a dark vignette.
• Adjustment Brush
  • The buttons are gone, so it’s now either a single drop-down and amount slider, or the range of sliders.
  • New icon shows when no color tint is being applied.
  • Show/hide pins and overlays are now in the toolbar when the Brush/Gradient are active, so no more having to remember the shortcuts.
• Crop – the list of crop ratios has been tidied up to combine identical ratios like 2×3 and 4×6.
• Greyscale has been changed to Black & White throughout.
• AutoTone now includes Fill Light.
• Sync/AutoSync now has a switch next to it to easily switch between the two.

Slideshow

• Slideshows can now be exported to MP4 video format for uploading to video sharing websites, including your music track.
• Mac version is no longer tied to iTunes, matching the Windows behaviour.
• You can now sync the length of the slides to the music track length.

Print

• Custom Print Package
  • New custom layout option for different images in different sizes (without resorting to hacks!)
  • Drag and drop to create a flexible layout.

• Page background color can now be changed.

Watermarking

• New watermarking allows a simple text or graphic watermark to be applied in Export, Publish, Print and Web.

Backup

• Backup has moved to quit rather than startup, by popular demand!
• There’s a new checkbox in the backup dialog to run optimize catalog after the backup.

Other bits and pieces

• The breadcrumbs bar on the filmstrip now has a Favorite Sources option.
• The Select Catalog dialog has had a facelift.
• Library menu > Show Missing Photos creates a temporary collection of all missing photos instead of having to go through Synchronize Folder.

System Spec Changes

• System specs have increased to a minimum of 2gb of RAM on Windows
• No more PPC for Mac, Intel processors only.
• No more Tiger – Leopard or Snow Leopard only.

Upgrading

This is still in early stages – even earlier stages than the 2.0 beta – so there are plenty of bugs. It’s not likely to blow up your computer, but you are strongly recommended not to switch your entire workflow over to the beta at this stage. It’s been released for testing and feedback on the new features, and the beta period is likely to be longer than that of 2.0 beta. It won’t allow you to upgrade 2.x catalogs to the beta, but the final release will.

Lightroom 3 Beta is not feature-complete – there’s more yet to come in the final release.

And I’ve been busy… my new book release updated for Lightroom 3 Beta is available for immediate download! Read on to the next blog post for more information!

To coincide with the release of Lightroom 3 Beta, I am proud to announce the release of my new book – Adobe Lightroom 3 – The Missing FAQ – and the rough cut is available for immediate download.

The Lightroom 2 version of the book’s had such great reviews, I had to update it for version 3!

You can pre-order the final Lightroom 3 PDF or paperback, which are due for release at the same time as Lightroom 3 final, and anyone pre-ordering gets immediate access to the PDF rough cut free of charge.

What’s a rough cut?
A rough cut of a book is like a beta version – it’s not finished, but it’s in pretty good shape. I’ve still got lots more to add yet, but just like the beta of the program itself, I’d love to hear your feedback, whether you come across a question that I’ve missed, or something that’s not clear, or you just want to tell me how much you love the book, I’d love to hear your thoughts.

What’s in this new release so far?

• Questions about the new Lightroom 3 features
• Lots of general new Lightroom questions that have appeared on the forums in the last 15 months since Lightroom 2’s release.
• Existing questions have been updated for the changes in Lightroom 3 beta.
• A new page layout which is easier to read, with space in the sidebars for notes.

What’s yet to come?

• No doubt lots more Lightroom 3 questions – I’ll be watching the forums carefully during the beta period to pick up the new questions, and depending on how many there are and the length of the beta period, there may be a rough cut update or two along the way.
• The new Lightroom 3 features in the final release – the beta is far from feature-complete.
• Lots of other general questions – I have a database of 6000 interesting forum threads and complete email conversations I’m still sorting through!
• A full index in the back.
• Anything else you suggest – I’m open to suggestions.

So what are you waiting for?

Pre-order Lightroom 3 PDF version – and get access to the rough cut now – £14.95 (approx. $25 US)*

Pre-order Lightroom 3 Paperback & PDF version – and get access to the rough cut now – £24.95 plus £3.50 shipping (approx. $48 US total)*

* The boring legal blurb – exchange rates are approximate and will be charged by your PayPal or your credit card company.  Payment will be taken at the time of placing the order. Pre-orders can’t be cancelled – but you won’t want to anyway.

Ok, the news is a day old, but someone kindly pointed out I’d forgotten to post it.

Download links:
Windows http://www.adobe.com/support/downloads/detail.jsp?ftpID=4508
Mac http://www.adobe.com/support/downloads/detail.jsp?ftpID=4507

Lots of new camera releases including Canon 500d/T1i, Canon SX1 IS and Nikon D5000.

There’s a few bug fixes, including the irritating crop bug:

And new DNG options for those who use the DNG format, taking into account the updated DNG specification and still allowing for backwards compatibility.

It’s a good stable update, so download it now!

There seems to have been a recent flurry of plug-in releases, with many being real time-savers, and adding great new functionality to Lightroom. Here’s a few of the latest additions for you to explore:

SLR’s with video have quickly become popular, but until now, Lightroom hasn’t had the facility to import or manage those video files along with your photos. Jeffrey Friedl has done a great job of incorporating that into Lightroom, with his Video-Asset Management plug-in.

You’ll also want to explore his many other plug-ins, including uploads to SmugMug, Flickr, ZenFolio, Picasa Web, and Facebook. He’s also the author of my favourite Metadata Wrangler tool, GPS tools, and a few others besides.

Tim Armes, author of the well-known LR2/Mogrify plug-in has also been busy writing, and has released LR2/Tree Exporter, which can replicate your folder structure when exporting. Very neat! LR/Transporter is another of my firm favourites, as well as LR/Enfuse and LR/Blog.

Sean McCormack of Lightroom Blog has been busy with Twitter plug-ins, with export plug-ins for both TweetPhoto and TwitPic.

Many people have asked recently about an FTP export plug-in – if you download the SDK and unzip it, in the Samples folder you’ll find a ready built FTP upload plug-in. Don’t worry, there’s no programming involved! Install just like any other plug-in, and it’ll appear in the dropdown list at the top of the Export dialog, where it currently says ‘Files on Disk’.

There are more plug-ins appearing every day, so keep an eye on Lightroom Exchange for the latest.

It’s true, the watermarking facilities currently in Lightroom 2 are a bit limited. Ok, very limited! But all is not lost… Lightroom plug-in programmer Timothy Armes came to the rescue with the well known LR2/Mogrify plug-in, and LR/Mogrify before that, adding fully configurable presentation options. LR2/Mogrify is donationware, and the trial allows you to process up to 10 images at a time, so you can see how well it works.

At first glance, the LR2/Mogrify interface can looking a little complicated, but that’s just because it’s so powerful. Let’s cover some of the basics that you’ll use when watermarking or signing your images.

The first thing you’ll need to do is install the LR2/Mogrify plug-in. Tim’s written full instructions on his website, so I won’t cover that here. In short, Windows users need to install both ImageMagick and the plug-in, whereas Mac users only need to install the plug-in.

Once LR2/Mogrify is installed correctly, you’ll see the Post-Process Actions section in the lower left corner of the Lightroom Export dialog. LR2/Mogrify can be used in conjunction with any of the other standard export options, such as resizing, sharpening, etc., and before any other export plug-ins.

First of all, let’s look at borders. Click on Borders in the Post-Process Actions and press Insert to add that panel to the Export Options. To add a border, select the width for each edge and the colour – and repeat for additional borders. You can alternative different widths and colours to create more interesting borders, or you can just keep it simple. The results of layering multiple borders can be seen below.

Now how about signing your image? Going back to the Post-Process Actions section and selecting Text Annotation is one option. You can choose the size, font, and positioning of the Text Annotation. You can even use that same Text Annotation section to add the EXIF data about your image using the ‘Add Token’ button to select the information to show.

One thing to be aware of – if nothing seems to be happening with the Text Annotation, try a different font. Mogrify can be a bit fussy about which fonts it will use! If your preferred font isn’t working, you can always use a graphical watermark instead – we’ll come back to those in a moment.

And here’s the result of those combined settings:

But what if you need to overlay a heavier watermark, or you want to add a graphical logo instead? Again, it’s simply a case of selecting the correct Post-Process Action – in this case the ‘Graphical Watermark’ option. You’ll need to have created your watermark image in a pixel editor such as Photoshop, and if you want to include transparency, you’re best off using PSD rather than PNG files, as there are some controls unavailable for PNG resizing.

These are just a few of the options available – have a play, and see what you can come up with. To get you started, I’ve uploaded the Export Templates and watermarks that I’ve used – you’re welcome to download them from here: http://www.lightroomqueen.com/downloads/mogrify-downloads.zip If you unzip the downloaded folder, you’ll find 2 folders inside – ‘Export Templates Mogrify’ and ‘Watermarks’. To install the Export Templates, put the ‘Export Templates Mogrify’ folder inside the Export Presets folder – you can check the location on your system by going to Lightroom’s Preferences dialog, choosing the Presets tab, and pressing the ‘Show Lightroom Presets Folder’ button. Obviously the presets are looking for watermarks and fonts on my system, so you’ll need to update the locations to point to the files on your own computer system.

If you have any problems, drop by www.lightroomforums.net and we’ll talk you through it!

Tim Armes has just released an update to his LR/Transporter Lightroom plug-in. This is hot off the press – it’s not even documented yet.

The new feature is for Lightroom 2 only. Many online ordering cart systems will provide a text file with a list of the files that the customer has chosen. Particularly for large orders like weddings, it can take a long time to manually select all of the images in Lightroom ready for ordering – but no more! LR/Transporter will now read that text file and mark the files for you.

To use:
Download LR/Transporter http://www.photographers-toolbox.com/products/lrtransporter.php A trial version is available to see how it works, and it’s well worth a donation to unlock it.

Installation instructions are here: http://www.timothyarmes.com/lrtransporter.php?sec=install

As with any plug-in that modifies the catalog, make sure your backups are current.

Open your catalog and select the files from the wedding in question.

Go to Library menu > Plug-in Extras > Mark Images using LR/Transporter

In the dialog, navigate to the text file containing the list. It just needs to be a basic text file, with 1 filename per line, and nothing else. (It’s also possible to use CSV files using the Import Metadata using LR/Transporter).

Choose the options you want – the examples below show which filenames will be matched as you change the dropdown lists.

Press OK, and the matching images will be marked.

To find and filter those images, select the Metadata filters from the Filter Bar and select Marked by LR/Transporter in one column. Your options will be Yes or No – yes being the ones that matched the text list.

[Warning - this is quite long. I had originally intended to split it over a number of blog posts, but it'll be easier to reference as one post.]

Who has never said “hurry up Lightroom”?  Speed is one of the most popular feature requests from Lightroom users everywhere, and no doubt the engineers will continue working on Lightroom’s performance over time, but for now, there are plenty of things you can do yourself.  Some are obvious, some not so…

Speed Tips in Library module
There’s a big difference between rendering previews that have never been built or that need updating, and loading those ready-built previews from disc.  How can you tell the difference?  The overlay in Loupe view will tell you exactly what it’s doing – and therefore what you can do to help.

“Rendering Preview…” means it’s rendering a preview for the first time – and you’re having to wait for it!  You could set Lightroom rendering the previews when it imports, by selecting your chosen preview size in the import dialog – it’ll slow you down initially but once it finishes rendering, it’ll be much quicker.  For files that are already in your catalog, select them all in Grid view and go to Library menu > Previews > Render Standard Previews or Render 1:1 Previews, and go off and leave it until it’s finished.  It’ll skip any that already have current previews, and you’ll find browsing much quicker when it’s finished.

So what size previews should you render?  If you want to quickly zoom into 1:1 view in the Library module (not Develop), then it’s a no-brainer – render 1:1 previews rather than Standard-Sized previews, either in the Import dialog or using the menu command noted above.  On the other hand, if you rarely zoom in Library module, you’re better off using Standard-Sized previews, as they’ll take up less disc space and be quicker to read from the cache.

If you see the “Rendering: Higher Quality…” overlay, it means the existing preview is too small or too low quality.   If you’re seeing that overlay in Fit or Fill view, you’ll want to reconsider your Standard preview size.  You’ll find those settings in the Catalog Settings dialog under the Edit menu (Windows) / Lightroom menu (Mac).  Generally speaking the Medium quality setting is fine, but you may decide to increase the Standard preview size from 1440 to a larger size if you have a high resolution screen and regularly see the “Rendering: Higher Quality…” overlay.

“Rendering: File Changed…” means, well, that’s the file’s changed since the preview was created.  That could mean that you’ve made changes in the Develop module, using the Quick Develop panel, or by applying a preset.  Using the Render Standard Preview menu command to update those previews while you do something else will speed up your browsing.

“Loading from Previews…” is the overlay you’re aiming for – that means your existing preview is being loaded from the preview cache, which is the quickest option.

Speed Tips in Develop module (or making Quick Develop changes in Library)

First, you need to understand the difference between Library module and Develop module.  Library shows you lower quality previews from the previews cache.  Develop, on the other hand, assumes you need an accurate view, so it first shows you the preview from the preview cache, then does a quick read of the raw file, frees up the sliders for you to start working, and then finishes loading properly, before it turns off the “Loading…” overlay.  You don’t have to wait for the overlay to disappear before starting work on the image – and if you find it distracting, you can turn it off in the View menu > View Options > Loupe panel > ‘Show message when loading or rendering photos’.

That’s all well and good, but that’s still a lot of raw data to load and process each time you switch images.  Have you ever noticed, though, that when you adjust a file in Develop, move to another image, and then come back to that first image again, it loads much quicker than it did the first time?  That’s where the Camera Raw cache, also known as the ACR cache, comes in.  When Lightroom reads the data the first time, it adds it into the shared Camera Raw cache.  When you load that image into Develop module, where possible, it will load that cached data, which is much quicker than reading and processing the original raw file data.

By default, that Camera Raw cache is only 1gb in size, and when new data gets added, the oldest data is removed.  With only 1gb of space, that happens quite quickly, so you’re not seeing the benefit.  If you go to Lightroom’s Preferences dialog, and look in the File Handling tab, you can change the cache size to suit – up to a maximum of 50gb.  Bigger is better!  You can also change the location if you wish to – but make sure it’s on a fast hard drive.

Once that data is cached, it’s much faster moving between images in the Develop modules – almost instantaneous on high end machines.  Of course, that is only helpful when Lightroom has recently read the raw file, and added it to the cache – and there isn’t currently a menu command to pre-load the Camera Raw cache.  All is not lost!

There’s a trick to pre-loading the Camera Raw cache – in addition to actually viewing the image in Develop module, there’s another obvious time when Lightroom has to read (and therefore caches) the raw data – namely, when rendering previews.  If you haven’t already rendered previews for your files, simply using the Library menu > Render Standard-Sized Previews command will do the trick.  If, however, you already have current previews, you can force them to re-render by making a minor or reversible change to the images (i.e. by using a Quick Develop button) and then using the Render Standard-Sized Previews menu command.  Leave it to finish, and by the time you come back, even the Develop module should be moving through the images at a much more comfortable speed.

Dispelling the Catalog Myths

It’s true that large catalogs can be a little slower than small catalogs – but we are talking BIG catalogs.  It’s not generally a good reason (any more) to split your library into 300 different catalogs – that just defeats the object of having a DAM system like Lightroom.

If you find Lightroom is feeling a little sluggish, find the Catalog Settings dialog under the Edit menu (Windows) / Lightroom menu (Mac), and press the “Relaunch and Optimize” button to perform database optimization.  It’s worth doing regularly, and any time you make significant database changes like importing or removing large numbers of files.

Finally, Hardware Tips & OS Tweaks
There is no question, Lightroom loves good hardware, but it can still run nicely on older systems too.  Do make sure you’re running the latest Lightroom release (currently 2.3) as performance improvements have been made to each release.

The system requirements are listed as Intel Pentium 4 or equivalent (i.e. a processor with the SSE2 instruction set or later), with 1gb of RAM and 1gb of hard drive space.   Now let’s be clear – those are minimum system requirements.  It’ll run – well, it’ll walk!  But if you start trying to feed 5d Mk2 files into Lightroom with a computer that was in the Ark, don’t expect it to be fast, and don’t complain about the speed.  If you’re going to spend money on the latest and greatest cameras, bear in mind that your computer hardware may also require a helping hand with those new super-size files.  Yes, even those sRAW files. 

If you’re working with existing hardware on Windows, check your graphics card.  You don’t need a heavy-duty graphics card to run Lightroom, but you will benefit from the latest drivers that are available from the graphics card manufacturers.  If you haven’t checked recently, that’s your first port of call for a free and easy performance fix.

Next, if you have an nVidia graphics card (Windows again), a quick Google will bring up numerous pages of tweaks which can make a massive difference to Lightroom’s speed, particularly for sticky sliders, slow preview refreshes, and Adjustment Brush problems.  Most notably, disable the nView software which is installed along with nVidia drivers, as there are known conflicts.  Other nVidia tips can be found on these posts:
http://www.thejohnsonblog.com/2008/09/06/lightroom-2-and-nvidia-performance/
http://www.flickr.com/groups/adobe_lightroom/discuss/72157607074073712/

Hard drives are another obvious place to look.  For a start, you’ll want plenty of space on your hard drives, particularly the boot drive, as your computer will get slower as you start to run out of space.  If you’re on Windows, defragment your hard drives regularly too.

Hard drive connections can also slow down Lightroom, due to the amount of data transfer when working with large files.  Internal drives will usually be quickest.  If you have to work from external drives, eSata and Firewire800 will be much quicker than Firewire400 or USB.  Ideally your catalog (and the previews alongside) will be on a different physical drive to the image files themselves (just another partition of the same drive won’t help).

If you’re looking for new hardware, you may be wondering if Lightroom can make use of multiple cores – and yes it certainly does.  I’ve seen it use up to 650% of my 8-core machine when running processor intensive tasks such as multiple exports or rendering previews.

Lightroom also loves plenty of RAM, but bear in mind that you’ll need a 64-bit operating system to really take advantage of large amounts of RAM.  If you have more than 4gb of RAM, you’re most likely to see improvement in the responsiveness of Develop module by using the 64-bit version.

And finally, a little logic.  Virus protection constantly scanning the same files that Lightroom’s trying to use will slow you down.  Consider excluding the catalog (*.lrcat), the previews file (*.lrdata next to the catalog), and the ACR Cache (check the Lightroom Preferences dialog for the location) from the live scan, and perhaps the images themselves.

The less junk you have running in the background, the better, particularly on older slower machines.  That includes those fancy little system tray programs that load on startup.

That’s all for now – if you have any favorite speed tips, feel free to drop them in the comments below!

Edit a file in Lightroom using the new local adjustments – the gradient tool or adjustment brush – and then open that file in Photoshop CS2 via Edit in Photoshop or Export…. and if you try to save it as a jpeg, Photoshop will complain with an error message which says “Could not complete your request because of a program error”.  Why?

Ok, it’s a bug… but for once, it’s not a Lightroom bug.  Photoshop CS2 trips up on some perfectly legitimate metadata that Lightroom saves into the files when you’ve used local adjustments.  CS3 and CS4 behave nicely with this metadata, but CS2 is no longer updated and so the bug will never be fixed.  What can you do about it?  You have a few options:

1. Update to CS3 or CS4.
2. Check the ‘minimize embedded metadata’ checkbox in the Lightroom Export dialog, which will strip ALL of the metadata.  It solves the problem, but leaves you short of any metadata in your files.
3. Use Jeffrey’s Metadata Wranger to strip just the problem metadata from the file.  By far the best option!

How to use Jeffrey’s Metadata Wrangler

To use Jeffrey’s Metadata Wrangler export plugin, you’ll first need to download it from: http://regex.info/blog/lightroom-goodies/metadata-wrangler and install it using the instructions here: http://regex.info/blog/lightroom-goodies/plugin-installation/

Then select the plugin in the lower left of the Export dialog, and you’ll see the additional section appear in the main Export options panel – scroll down if you can’t see it.

The only part you want to remove is the ‘crs’ block marked in red in the screenshot – all of the rest of the data can stay.

Any images exported with the ‘crs’ block removed will quite willingly save as a jpeg even with Photoshop CS2.

If you’re just starting out with Lightroom, there are a few CRUCIAL bits of information which will save you hours of headaches and untangling. They’re the kind of thing that just make you say “I’d wish I’d known that before….” These are my top ten gotchas, direct from the forums.

1. Lightroom is all about non-destructive editing – so don’t try to save over your originals.
2. Lightroom doesn’t ‘contain’ files, it just holds data about them – so don’t go deleting your originals thinking that they’re safely stored in Lightroom.
3. Lightroom’s backups don’t back up your originals – you still need to do that.
4. Lightroom’s catalog is just a database, and databases can become corrupted – backup regularly, and keep older backups for a while.
5. Lightroom needs to know where the files are – don’t move or rename files outside of Lightroom, i.e. in Explorer or Finder, otherwise you’ll have a long job fixing all of the links.
6. Lightroom will not match your cameras rendering when working with raw files as it’s just raw data, but you can use the new profiles to emulate the manufacturer’s look for some cameras, or you can build your own profile to match.
7. Lightroom offers a choice of different colour spaces when you output, and AdobeRGB/ProPhotoRGB will look odd in programs that aren’t colour managed (like web browsers). Use sRGB for screen output like emailing or uploading to the web.
8. Lightroom’s Grid view behaves differently to other views – anything you do in Grid view applies to all selected images, whereas other views only apply to the most selected image.
9. Lightroom has 3 different levels of selection, not 2. Notice the difference, otherwise you could accidently apply a setting to multiple different images.
10. Lightroom’s Flags are local to the folder or collection, whereas star ratings and labels are global. This means that a photo can be flagged in one collection but not flagged in the folder.

Any more gotchas or blinding flashes of the obvious that you wish to add? You know, the things that make you go ‘Duh!’
