P: Jpg exposes bugs in QImage and ZoomBrowser

Since a recent upgrade to CS5 (I guess 12.0.4 and certainly the current version) JPG files I've saved take about 1000x times longer to open in Canon ZoomBrowser 6.7.2.33 (the latest version). When I say 1000x I mean 1000x. Recent jpg are taking over 30s to open a single image! I raised this with Canon sending then old and new jpg (created using an older version of CS5 and the latest) from the same CR2 file. They said:

Extracting the EXIF data from both the good and bad images we found that the JPEGInterchangeFormatLength (JpegIFByteCount) value is bigger in the bad files.
JPEGInterchangeFormatLength shows the number of bytes of JPEG compressed thumbnail data.

We believe that this higher number is causing the problem as the ZoomBrowser EX application is trying to use the EXIF data to generate the thumbnail images, and to display the files. We were able to reproduce the issue in our test environment.

We would recommend you to contact the Adobe support in order to find out if there were any related updates released in the last few weeks that possibly was installed on your computer manually or automatically.

Please can you investigate what changed recently in CS5. And how I rescue my recent jpg images that I've needed to create for my clients. If you need the images that I sent Canon for your investigation then please let me know.

    So you're not seeing any corruption, just JPEG files with what you believe to be the incorrect profile?

    I have applied my modified action as mentioned above, but it still does not provide a sure thing cure to the problem. I have found that if I reload the offending file into CS5 and Convert to profile/Adobe RGB and then Save As over the original Tiff or PSD manually, it seems to save the following jpg file as Adobe RGB okay.

    BTW, how do I get the addition of the Convert to profile in the action to apply it without stopping to ask me to press Enter. Have I missed/forgotten something?

    I have been having a great deal of trouble with colour instability since recent updates to CS5 also. Am running XP64, CS5 12.0.4, Camera Raw 6.4.1. I run Adobe RGB 1998 workflow from camera to printer.
    Seems to be totally random result of some files returning an sRGB colour space and some returning AdobeRGB 1998 when converted to jpegs for printing. Same result for scanned images too, so it is not the camera. The 32bit version appears to be worse, but the 64 bit version does it too.
    EXIF details in Bridge show Adobe rgb but this is not the case when viewed with a hex editor. I processed the same two files (one a psd & the other a tiff) no less than seven times with totally random results. I could not return a pattern. Sometimes sRGB & sometimes Adobe!

    The only way I can get around it is to include a new line in the action that sends the files to the print output folder which is: Edit/Convert to profile/AdobeRGB 1998.
    This seems to ensure me the result I need to print accurately.

    Note to ADOBE - NOT HAPPY!!

    Hi,

    For those having problems, can you reply back with the version of the Camera Raw plug-in you have installed and the workflow settings? Also what OS are you using?

    You can quickly find the CR version this way using Photoshop menus:
    Win: Help> About Plug–In> Camera Raw...
    Mac: Photoshop>About Plug–In> Camera Raw...

    regards,
    steve

    I have 12.0.4 and am having a similar problem that is costing me alot of time and frustration. I am opening files in ACR and then working the files and saving them as jpegs in RGB space. When I open them to print in Q-image some of them are in sRGB on no profile at all! This is not user error, I have not changed my system here for a long time. Please help us out.

    It'd probably be difficult to prove anything. You'd have to know when the update was pushed to your computer, how long after that it was until you used the image processor on raw files, AND the problem is not consistent: doesn't always happen unless the conditions are right. I think Adobe has enough info now to find/solve it. Let's give them time to respond. Only thing I can say for certain is that 12.0 did not have the problem and 12.0.4 does. I have no idea which version in between actually caused it but I suspect it is the latest (12.0.4) just because of the increase in reports of this problem from my customers in recent weeks. Nothing before May.
