The picture that I took looks a lot different on the website than it did when I had it on my computer. A lot of the color was lost. Anyone have any ideas about what I could do next time to avoid that? I don't know if it is with how I saved the file, or just the limits of the website.

thanks,
elizabeth

Putting the picture on our server will do nothing physically to the color. One thing that might is viewing it on a white background -- with the effects of color perception. Could be that it?

Or do you see something more specific?

Try adjusting your computer with the Adobe Gamma program. I was blown away by how far off mine was! Thanks to this site, I was able to fix it.

Most mondern video cards let you adjust the gamma directly as well, if you don't have Photoshop. check this link for some gamma-adjustment pictures.

To do it you just right click on the desktop, click the Settings tab, and somewhere in there should be a set of 'Color Correction' tools that will let you adjust the gamma/brightness/contrast of your video card to get the proper results. See the other thread for more details!

Powerstrip will let you adjust gamma also.

ok...I need help. So, if I am understanding the rectangle picture; the inside rectangle and outside rectangle should be the same (or at least close to it). On my monitor, they are not. So, I go into display, then into settings, and now how can I change my gamma levels?
Do you have to have special software to do that? My computer isn't that old, but the user guide to the graphics card I have has no info about gamma levels.
part of the problem was my computer at work is set up much differently than what I have at home. But there is also this problem that my home comp may not be set up optimally.
thanks for all the help already, and any that is forthcoming!

Whoops, I should have been more clear. :) Once you click on the 'Settings' tab, there should be a button on the bottom of that page that says 'Advanced...'. Click on it and a new dialog will open up, hopefully it will have a tab called 'Color' or 'Color Correction' on it with some sliders that let you adjust the brightness and gamma. You shouldn't need any special software, almost all video drivers will let you set it. Make sure you can see the colored rectangles, and adjust the gamma until they match as closely as you can get them. Most drivers will also show you a little square with a curve representing the current gamma, and some will let you adjust red, green, and blue separately. Try to adjust all three colors at the same time to get the match, this is usually enough to get decent results!

My guess is that it has to do with color profiles. Photoshop 6.0 will allow you manage the color profile of the images you work on. When I work with images that are for multimedia purpose, I set the color profile matching my monitor type. I find that this allows the images to appear the same no matter what application I am using to view it. When I work with images for print, i set the color profile to my printer. With this setting, the images I work on in Photoshop does look like what it does if I view it using a different program. But ideally, this should give me a good approximation of what my images will look like when i print them on my printer (while I am working in Photoshop).

Here is the nasty twist about color profile for multimedia purposes. The same image will not look the same from one monitor to the next, unless you are using an image viewing program that makes use of color profiles. The only program I know that uses color profiles is Adobe Photoshop. Does anyone know of another program that makes use of color profiles?

About the only way to ensure that people will see the image exactly as you see them is to embed the image with a generic profile (for example, sRGB IEC61966-2.1). Then have the other person viewing it use Photoshop, and telling Photoshop to make use of the embedded color profile.

If anyone has information contrary to what I noted above, please post a response

Q Image also allows the profiling.

thanks for all the help! I was able to fix my monitor at work, still trying to figure out what to do at home (although that one is not as off as my work one was).
thanks again!
