The problem I have is that the software will simply not open a JPG I have saved in photoshop… it doesn’t matter what the file is, all that happens is that I take a file, even one processed by Photolab, open it in Photoshop, resave it, and then Photolab simply won’t open it and tells me the file is corrupt.
It applies to ANY file I save in Photoshop at all. What I have discovered though is if I then resave the file in Photoshop as a TIFF, and then resave that as JPG it opens in Photolab. I’ve included an example here.
But the forum platform can modify the images a bit. To have a clear test, could you please upload your image (and a sidecar if any) via upload.dxo.com with your forum name in the field and let me know when ready:
Some time ago I noticed, that PL couldn’t handle ‘Alpha channels’, but that seems to be no more of a problem. ( And of course, PL can’t handle layers. )
Just remembered – somewhere there was a problem with the compression rate / mode, when saving a TIFF-file.
