i found two versions of the same image, and on my computer the two images looked different. however, for other forum users, they looked identical. but then i made a screenshot of the phenomenon, and on the screenshot others could see that they looked different, at least on my computer. i still dont completely understand what happened there.
I am not sure what exactly is happening to the pictures in the thread you reference, since they appear identical on my screen. However, something to keep in mind is that the photograph needs to be white balanced properly, your monitor/screen needs to be calibrated properly, and the way the file is stored on the website can also affect the color we see (if the picture is to be printed, then the printer must also be calibrated). That is why graphic artists use Pantone colors. They are colors that have a specific values and the artist can know that a color will print properly as long as the printer is calibrated, even if the color does not display correctly on their monitor/screen. Colors can really be affected by the calibration. That's why in the thread that I will be posting later about color temperature of the lights and other photography techniques, I will include a WhiBal card since it is calibrated and consistent card to card and some common every day items that people should have in their house so that they can compare the colors in person. As far as your point in your thread about the compression changing the color, it didn't for most people, so I doubt that the compression caused the difference. I think some other factors to explore would be what browser (both company and version) people were using that saw the difference, what manufacture screen, video card, and firmware versions people who saw the difference were using, and so forth. All of those seem more logical factors to consider to me. But we are starting to hijack this thread. I just wanted to show my Pastel and how photographs may be corrected to show what the eye sees. That is why I suggest that people use something like a WhiBal card so that others can check the balance if they suspect something. As I look to post more pictures of my snakes, I will post cropped pictures, but always keep the original that has the WhiBal card in case there is a dispute about the accuracy of the colors in my photographs (something neat about using a WhiBal card is that you could take your first picture of the WhiBal card and then as long as the light conditions don't change, one reason to use a light tent/light box, you can use that first shot to correct all subsequent shots, take a look at the WhiBal website videos http://michaeltapesdesign.com/whibal.html).
