If you're doing any converting/saving in PhotoShop, this could be the culprit:

... and Mike SP, after reading Mike Chaney's explanation of the problem in http://ddisoftware.com/tech/qimage-ultimate/qimage-exposes-photoshop-cs5-%2812-0-4%29-jpeg-corruption-bug/


I hope you noticed that he made a fix to prevent the problem, but the fix was incorporated into Qimage Ultimate.

Qimage Ultimate v2012.104 has been updated with better error checking that can detect and fix the problem.  I do not plan to update the retired versions (Lite/Pro/Studio) since they are not under active development and this is essentially a workaround for an Adobe bug.

It might be worthwhile to consider the new Qimage Ultimate.

I hate to admit how many hours I have wasted getting an understanding of what the h*** was going on with my workflow that had taken so long to create but which worked great for several years and suddenly I am getting the wrong colors and JPEGs with sRGB color space when I had processed them from raw into the aRGB color space and had PS set for aRGB and assumed I was still getting files in the aRGB although Qimage indicated that they were sRGB...  Confusing and FRUSTRATING Angry

My work flow will change to use TIFFs for printing (no big deal since I now understand what the problem is) and sRGB JPEGs for emailing -- EXCEPT I just do not have the time or patience to go back and reprocess hundreds of images -- no wonder Adobe is not admitting the JPEG corruption bug.

AND I may very well upgrade to Ultimate and ignore the many things it can do since I will not move away from C1 for raw conversion.  Qimage Pro does EVERYTHING that I need and does it PERFECTLY -- wish that a "Light" version of Ultimate would be developed for those of us that do not need most of the bangs and whistles in Ultimate.

I DO believe that to be the culprit.  I deactivated CS5, uninstalled 12.0.4 and rebooted, then installed 12.0 x32 from the installation disk and it seems to behave very well in regard to handling aRGB files.  IF I find this to be the case after a few MORE hours of experimenting, I will NOT update it since that seems to fix my problem of aRGB files being improperly saved as sRGB files by Photoshop.

The sad thing is that Adobe has known about the CS5 12.0.4 bug for two months now and they haven't bothered to fix it.  I would have thought that Adobe would have enough respect for their product and their customers to put out a prompt fix when the bug results in a clear case of file corruption.  Now with Adobe giving the boot to 750 employees, I guess I can stop checking to see if 12.0.5 has been released: who knows if it will ever be released!  I had the error correction fix in Qimage Ultimate in less than a day, which detects and corrects the Adobe file corruption.  You would think that if one person can do that in one day, a company who can lay off 750 employees yet still be in business... could at least do it within a week or two.  Wink
