    File Types
    Everytime I take pictures I have to edit them which means I have to save them as psd files. After that I have to re-save as a jpeg file so I can host it on photobucket. Problem with this is that whenever I do this, I get a decent image, but the colours are off compared to what I made in PS.
    So does anyone know a better file type to convert my psd from, that is compatible with photobucket.
    Or is there a better way to convert my psd to a jpeg so I don't lose my colours.
    Thanks,

    Ruke,
    When your saving the images to JPEGs for photobucket are you converting the colorspace to sRGB? If not that will be your color issue.

    Give that a try.

    okay so i was doing it right the entire time.
    I dont know whats up. Someone told me that the safari browser has a different colours space.
    i dont really know what that means, but it seems technical enough to be right

    My understanding is that Safari will assume an untagged image to be RGB and not sRGB, and I am unsure if there is a way to change that.

    However most other browsers will assume sRGB and therefore it is to your benefit to save them in that color space unless your intended viewers are all using safari.

    To save my images using photoshop as sRGB, I simply go to Image=>Mode=>Convert to (Color space) profile. I am not at my workstation and do not have photoshop, hope that is the correct path.

    As mentioned above, and in a little more detail, the issue may be that Photoshop understands color management while most PC based programs do not. So, if you are viewing your shots in Photoshop, and then posting them, and then viewing through a non color management aware browser, you may see color shifts.

    This is the Adobe RGB / sRGB issue mentioned above. Please note that converting files to jpg doesn't change the color space, so the greatest likelihood is that you are using Adobe RGB for your images while everything you are viewing the images with after posting is interpreting them as sRGB. This does cause color shifts.

    There is a straightforward fix. With Photoshop, you can use the Edit->Convert to Profile dialog to change the profile to sRGB with essentially no color shift (small loss, since sRGB isn't as wide a gamut as Adobe RGB). Once done, you should get more consistent color reproduction in browsers and non Mac computers, although it will still vary, monitor to monitor.

    Finally, if you are posting a large volume of images, you can automate this process with Photoshop CS2 at least. Check out File->Scripts->Image Processor, which will let you reformat entire folders worth of photos in one dialog, INCLUDING changing their color space to sRGB! I use this whenever preparing sets of image for web publication.

    One caution: the Image Processor doesn't know what to do with images that don't have any color space tagged to them and will stop if it encounters one. So, make sure all images you are feeding to it have a color space tag (all images from pretty much any decent camera are tagged, so this is a minor worrry).

    I must spread out rep more before giving Mac57 additional points for expanding on my replies. :-)

    This is a colour space mismatch issue.

    What are your profile settings in Save For Web?

    If your camera is set to Abobe 1998 colour space than you should set Photoshop to that Working Space and vica versa if your camera is set to sRGB. Incidentally, if you shoot in RAW than the colour space of your camera is irrelevant in which case you should check what colour space you have defined in your RAW editor/Camera RAW and set Photoshop to the same Working Space.

    If you are using Adobe 1998 then before you save for the web you need to convert it to sRGB which you do by Edit/Convert To Profile and select sRGB. Now when you go to Save For Web you need to click on the little black arrow in the top right corner of the image preview area and from the drop down list select "Use Document Color Profile".

    Now when you save your jpeg it will be in the sRGB colour space with an sRGB tag and will then display correctly in all browsers which only support sRGB.

    To be honest with you, I cant remember the last time i used animated gifs in my work.

    I tend to just use single frame stuff, The only experience i had was with some software years ago which did it for you. Have a look around google to see if you can find any apps.
