Lightroom is only sRGB-big problem for PSD images?
Does your Lightroom do this to you? :-P As a continuation of a post I made here last night (https://www.modelmayhem.com/forums/post … st19738616), I just found an issue with LR (my perceived issue anyways) and I wonder if any of you knew about this or noticed the same thing. I've always noticed that sometimes when I export files from LR, that the color or luminosity changes if I open the same file in Photoshop...even if it was edited and finished in photoshop. Sometimes the white areas (255 per RGB channel) would be exported with decreased intentisity (droppig to 247 per channel). My process is I shoot in Adobe1998 and then import into Lightroom. And if I export it from LR it goes out as sRGB. If I edit in Photoshop, then it goes in there through LR as ProPhoto RGB and is saved in that color space in a PSD file, which then back to the LR catalogue. When I export the PSD from the LR catalogue it goes out as sRGB. WELL.... through some experiments and trials this morning, I discovered that the reason why my images that are finished in PS are coming out at decreased luminosity is that it seems that LR only lives in the sRGB color space. I assumed that it would convert the ProPhoto RGB in my PSD file *correctly* into the correct closest equivalents in sRGB. But the interpretation is not very good and I get a result that is somewhere in between viewing an sRGB and ProPhotoRGB image in the sRGB color space. This was easily corrected by convered the image in PS to sRGB at the end of finishing, or just keeping the image in sRGB when editiing in PS from LR. Or bumping up the white slider in Lightroom to compensate (but now you're just guessing when trying to match what you did in PS). But now the issue is, to convert PSD files to sRGB, PS wants to flatten my layers (I always try to keep my layers intact). And all my PS files in the LR catalogue since day one are in ProPhoto RGB. Question: what should I do/what would you do? Does the very latest LR version exhibit this issue? Does this exist in CaptureOne? It will be a pain to go and fix everything, probably save from PS, including images on my portfolio, etc... Your feedback is appreciated. Jul 05 17 12:24 pm Link RonaldLee wrote: No, that's not true. Question: what should I do/what would you do? Don't flatten or change your existing working files. Check if you have some default development settings in LR which affect your white point. Jul 05 17 03:02 pm Link Ok. And where would I look in LR to see if the white settings are affected for non sRGB color space PSD's? It seems fine if the PSD is already in sRGB, but it seems the conversion from a different color space is creating the issue. Jul 05 17 04:05 pm Link Does the color space in LR's export preferences match the color space you're using in Photoshop? If not, that could be the contributing to your problem.

There are many things involved in your process, so to find the issue we need to investigate one thing at a time: Jul 06 17 12:34 am Link RonaldLee wrote: If by export you mean you're using the "Export" button from the Library module, then you have a choice in the "File Settings" pulldown as to what color space to use. You can select Adobe RGB, proPhotoRGB, sRGB etc along with the format (eg, jpg, psd, tif). Maybe you checked sRGB a while back and there it's stayed. Jul 07 17 11:37 am Link |
