Problem with colour in photoshop, probably dead simple to fix?

    Just something I've been noticing, when I open a pic outside photoshop it looks fine, nice saturation etc etc, when I open it in photoshop though it looks quite "dull", the colours are quite desaturated almost.

    Problem is these pics are for an exhibition so I don't wanna waste money and time on prints if their going to come back looking like the photoshop version.

    My monitor is all calibrated and that etc too. Could it be the colour profile in photoshop?

    Interesting problem but I think it might have to do with your colour profile settings in Photoshop. There are a few questions I would ask:

    What colour profile do you have loaded and what settings does the camera allow for colour?

    Do you have the same probelm with photos that were not taken with your own camera?

    Did you ever get this fixed?
    I had the exact same problem and a friend suggested trying this
    http://form.pbase.com/viewtopic.php?f=18&t=36914&sid=3493f1be783e78335761e38cc1315619

    or this
    "Making sure that your colors match
    If you work with photos in a wide-gamut color working space such as ProPhoto RGB or Adobe RGB, image colors may change when viewed in a web gallery by a browser that doesn't read embedded color profiles. If this happens, try converting the image profiles to sRGB (which most browsers use as a default) before optimizing them or including them in a Web Photo Gallery. Convert them to sRGB in one of the following ways. It is a good idea to work with a copy of the images.
    To convert a single image, choose Edit > Convert To Profile and then choose sRGB. See Assign or remove a color profile (Illustrator, Photoshop).
    To convert a folder of images, use the Image Processor. Choose File > Scripts > Image Processor. See Convert files with the Image Processor.
    If you use the Image Processor, you can save the files directly to JPEG format in the size that you want them. If you do so, make sure to turn Resize Images off in the Large Image options."
    Just tried it out on an image there and it worked perfectly. Reassuring to see as well in the help content that it mentions you can convert folders of work together instead of just doing it image by image.

    Hi
    I am new to all this forum lark, this is the first time I've ever posted to one of these........
    In response to your colour problem in photoshop I would like to echo earlier posts by saying this is a colour profile issue.
    First off you should ensure your photoshop colour settings are correct. You should decide what colourspace you want to work with , to make things simple there are two you should choose from, sRGB or Adobe 1998. sRGB is a small colourspace which was designed for use on the web, it is similar to most monitors colour gamut and therefore will display in a similar manner on most monitors. Adobe 1998 is a larger colour space which includes a lot more printable colours in its gamut, so for printing purposes this is by far the best particularly if you are printing them on a high end printer. To illustrate and mimic the problem you were having with your images in photoshop, if you open the same image which you know has the Adobe 1998 profile embedded in it in both Safari and Firefox (if you are on a mac) , the image will look very different in each browser, particularly if the image is highly saturated. The image will look as it should in Safari because it recognizes the image has a colour profile embedded, the image in Firefox looks dull because the browser assumes the image is in sRGB, so it treats the larger colourspace as if it were a much smaller. If you are on a PC you could save the same image in each colourspace and then open them in your browser, you should notice a difference, namely that the sRGB file displays as expected and the Adobe 1998 is dull. Your monitor will also affect the difference you see between the two.
    This is beginning to feel like I'm lecturing....
    So I'll try to be brief... In photoshop CS3 go to Colour settings and change your RGB colourspace to whichever you prefer, Adobe 1998 being the better option in my opinion, and most importantly under Colour management policies change the first option to "convert to working RGB" and tick the boxes beside "Profile mismatches" and "missing profiles" . This will alert you when you open a file that is not in the same courspace as photoshop. When there is no profile embedded things get tricky, you basically have to guess what profile the file is and assign it that profile and convert it to the working space ( this is the last option in the dialog box the opens when you open an image without an embedded profile), but of course it could be any colour space from any camera.
    All professional printing labs should print up a small proof for you to judge the colours on anyway, you could just crop a section 6x4 send that to them, they could also give you their printers profile for you to soft proof your image on your system but that's an entirely different ball o wax and it almost never does what it says on the tin.
    Best of luck and sorry if i went on a bit , it's hard to make a pithy reply about Colour Management , and I could go on......
