When I crop in LR using the ordinal aspect ratio and export as a jpg, I am unsure about the following;
1.Is it a 1''% crop
2.What will be the end result for image size, unlike PS I do not have anything to go by to tell me what my size will be.
3. If I have thrown away half the information by cropping and then try and print an 8X12 will LR fill in the blanks

I have seen slide shows where all the images are different sizes due to cropping; I do not want to have to export to PS just to resize the images to be the same.
Thanks

Hi Anthony, welcome to the forum!

Let's see if we can answer these one by one...

1. If you have an original file of, say, 2'''x3''', and crop some off, and then export to jpeg without no specific size set in the export dialog, it will create a file without interpolating extra pixels. So you would end up with a file of, say, 15''x25''.

2. If you want to export to a specific dimension, you enter those dimensions when you're exporting. I did a quick run down of the new export sizes in the 1.3 update (scroll down it to the pictures!) So if you wanted a file of 16''x26'', you'd enter those in the export dialog.

3. Yes, LR will fill in the gaps for you.

I just started using lightroom to CROP my photos 2:3 ratio and then export jpg for clients.

I usually export:

* 1 time for sideshow, web etc. 1'24*768 so that all my photos display the same size
* another time for print quality

My cropped 2:3 photos range any where from(rounded) 14''*21'' to 26''*36''. My question; should I just export these wide variety of cropped dimensions as is and let the client struggle with what sizes/quality they can print from each. OR configure my settings in LR to export all to 8*12(allowing for large or small prints), letting LR upsize/downsize (interpolation) as it see fits.

Sucessful practice suggestions?

Thx

This seems like a good thread to put this in, since the OP was somewhat about 1''% crops.

Say I'd like to export a 1''% crop at a size of 4'' x 4'' pixels. How can I do that in Lightroom? Keep in mind that any resizing on export changes the image from 1''%. Is there a way to see what the new pixel dimensions are of a crop before it's exported?

To address acutshall's latest question, I'd find out what the client would like, then either shrink them all to a size near the small end of your range, or export them to a suitable pixel size for the desired print size, even if that means some are enlarged.

I too have questions concerning croping/up-rezing/exporting. Having just learned LR will up-rez I played a little with one pic, but I'd like to see if I understand it right.
If you have a folder (and you're exporting the entire folder)with pics of varying sizes of edits due to different crops, and you set a size in the export dialog box, then LR will resize all those pics to that same set size. Correct?
If you have some uncropped, then you should set your export setting to that uncropped size and then LR will uprez anything smaller to that size. Still correct?
Does Lr do anything (like re-building or re-making them)to the ones that are already at that uncropped size? Anything that would cause any image degradation?

Lightroom has enough settings options that you can accomplish about any type of batch resizing. Your questions are tough to answer without knowing what settings you're using.

I would expect that your .jpg output quality determines whether or not an image is resampled. If you have it at 1'', it shouldn't degrade the images any more than the raw to jpg conversion must.

Go to View > View Options and you can set the Info Overlay (hit I in Loupe or Develop mode) to show 'Cropped Dimensions' which is the cropped pixel dimensions without any resampling.

Rowdy, Thanks for your reply, but I don't think you understood my question. First off, the jpg compression or output settings shouldn't have anything to do with up/down sampling. That is just a matter of adding or taking away pixels to obtain the desired size. Compression affects how much information is discarded and rebuilt each time the image is saved again. Two separate things.
The exact settings really don't matter for my question. I'm asking about the manner in which LR goes about resampling.

Ok, let's try an example then.
You have some images which uncropped are, say, 15''px x 2'''px.
You also have some images which are cropped to 1'''px x 12''px.

If you set your export to 15''x2'''px, and allow it to resample, the uncropped 15''x2''' px images will export AS-IS (there's no need to create or throw away pixels in that case), whereas the smaller one will be increased to fit, and larger ones will be shrunk to fit.

Does that answer it for you?

Welcome to the forum Rowdy, can you take a moment to fill in your signature in the UserCP. Thanks.

The problem with that is it isn't real-time. You have cycle through the views to get the dimensions updated.

That would make a useful feature request Winston.

Yes Victoria, thanks. That's exactly what I was hoping it would do. I guess we could now get into a big discussion about which method or software was best for resampling, but I think that's best left for another time and thread. Thanks for all you and Kiwi and Don the others do to keep us going.

LOL Rowdy. Nice sig. It's always useful to have platform details particularly, processor and memory, and PS/LR version numbers, so nice job!

Not to be too nit picky (I like your photos) but, are you really still at 1.3 or 1.3.1, highly recommended, if not.

Nice to meet you, Clint.
;)
