    RAW File vs DNG

    Exactly. My question is whether anything is baked into that conversion. Let's pretend for a moment that Adobe has a deficiency in their interpretation of a new camera's sensor. Not a bug exactly, some weakness. They fix it a year later. In that year you converted 1000 raws to DNG. Did it...

    RAW File vs DNG

    Thanks. One day I may find a program to look at the details inside and look more closely. But I still lament that Adobe's open standard lacks openness in terms of the actual conversion process. It just worries me that somehow it can allow non-supported cameras to magically be supported, yet...

    RAW File vs DNG

    Tim, your description would not much concern me, so much as everything you described is reversible. 5 offset 10 is still 15. What concerns me is anything they do that is not reversible, for example any kind of stretch applied, or any math applied to relative color channel (pre-debayer) values...

    RAW File vs DNG

    To Tim's point, I am not asking about the odd sensor type (though that's an interesting question) but more or less standard bayer matrixes. There's a difference in my mind between all those words and "original". My question is this -- if sensor site X has (800,900,850,300) for RGGB, do those...

    RAW File vs DNG

    I would hope so, but have you ever seen that written down by Adobe? I've always been frustrated with an "open" standard but the actual process Adobe uses in the conversion is rather opaque. My real question is this: if I have specific RGGB sensor site values do they remain unchanged in the...

    RAW File vs DNG

    So one thing I still cannot find written down clearly -- if you convert to DNG, and do NOT check the option to "embed original raw file" (I think the default is not)... Does it convert to linear data (referring to the definitions at the top of Roelof's posted article)?

    SmugMug Source

    To me it's a solution in search of a problem. If the problem is backup -- I haven't seen any sign they maintain versions and point-in-time recovery. More to the point, for large volume photographers I still think that upload speed is a severe limitation; until we can get the Comcast's of the...

    LR (PS) & Intel I5 11400 v. I7 10700F

    GPU shortages are tough now. I just did a new PC build, and am a bit worried as it's an AMD threadripper so no internal GPU. I had an old GTX970 I planned to replace but... well, haven't managed yet. It certainly is a concern. <Expletive deleted> cryptominers.

    LR (PS) & Intel I5 11400 v. I7 10700F

    This used to be an easier question than it is now. For a long time most human-wait time issues were best addressed by the fastest single core speed, not overall (cores X speed). With more GPU use, and more parallelism over past versions, it is harder to say which is best. Personally I'd lean...

    Curious new rank

    Extremely bad advice, sorry to be blunt, but it is dangerous advice. Bear in mind that email from addresses are surprisingly easy to fake, analysis of headers and searching email audit trails can sometimes validate them, but you should never assume that an email from address is legitimate. I...

    LR6.14 License Conundrum?

    If true, I guess Adobe has decided the number of people they will annoy is small enough they don't care. A shame really, when technical enforcement measures prevent people from using software they legitimately own (even if, to be fair, I think most of us feel you would be better off just...

    LR6.14 License Conundrum?

    In your Adobe account (under which you registered it originally) can you see anything? I'm not on the perpetual any longer, but have a vague memory you could see the devices there and remove them manually?

    Move LR catalogue to SSD?

    Because some people confuse catalog with images: it is more important to store the catalog (database) than it is to store the images on an SSD. Whether it will make a noticeable difference though is a different matter, primarily it may be faster browsing the library in grid mode; develop mode is...

    Deleting 1 to 1 Preview and Smart Previews

    Why do you think it's 1:1 previews that are taking up space, it could be standard size (which are not purged)? If you have 590,480 images, that's a lot of images. I have only about 80,000 or so and that's 96gig. that's somewhat proportional to yours. There may be some delay as purging is...

    35 mm Kodak slide film

    Gain in film emulsion is generally NOT addressed well by digital denoise routines, trying to do so will probably take out way too much detail. I don't have a good answer how to handle emulsion grain, just that the obvious is not usually good.
