I submitted this photo for the recent Sand challenge: 
It did ok, I never really care where my photos end up (but am curious always as to why some do fairly well and others bad). But in the photo above, I had lot's of comments about the color. Mostly being to oversaturated. I didn't think so, the sand there is really, really red and recent rains had made it look even darker. Anyway: I opened the photo here at DPC and then opened the same photo I submitted on my computer and compared the two. The one at DPC was MUCH more colorful and I now see why people thought it was over-saturated. The one on my computer is less 'colorful'.
So, I right-mouse clicked on my DPC entry and saved it to my hard drive. Then I opened both photos up side by side. The color looked exactly the same: not over saturated. I started looking at some other photos I have submitted and have noticed the same thing: in a DPC window the colors are much more vivid. Can anyone tell me why that is? |

What color space are you shooting/editing in? If it is Adobe RGB 1998 then it is a color gamut issue (the colors are getting clipped when converted to sRGB in the browser). When you upload to this site you should convert to sRGB, that is the native color space of anything on the internet. My next question to you would be is your monitor properly calibrated?

your sig is HUGEMUNGOUS !~
the calibration wouldn't make the issue he's talking about. the color space would.

| I've been looking over some of my photos - comparing what I uploaded to DPC to the original, and have found when viewing them, the color saturation levels in a DPC 'window' is roughly increased by an additional 20% then how I originally edited and submitted it. Can anybody else see this in their photos? |

I find it is the opposite for me. The colours I see in PS are much crisper and clearer than what I see in DPC. I find that once I upload, the colours seem more drab. So I then try to go back and boost saturation to compensate. Its a struggle to get it to look the same as it does in PS. ( I have checked all the sRGB settings and all that) hopefully I am not missing something!

| The calibration of the monitor can make a difference.. PS takes advantage of your monitor profile to display your image, where as a browser window does not. But like I said before, it is more likely an issue of color space. You want to save it in sRGB using the convert to profile option in PS. PS uses the Adobe Color Engine or Adobe ACE, you then have a rendering intent option which controls what happens to the out of gamut colors. Your best options are "Perceptual" which changes the colors that are out of gamut to a color that is within the gamut of the converted space, while also changing the colors that are within gamut slightly to preserve the color relationship with the out of gamut colors. Relative Colorimetric leaves the colors within the gamut of the converted space alone and only changes the out of gamut colors to fit within the converted color space. Both of the options will show very little change depending on the size of the gamut of the destination space such as Adobe 1998 to sRGB. |

It sounds like you're discovering the problem that most web browsers don't support color profiles. Safari is the only browser that comes with color profiles enabled by default. FireFox 3 has support, but it is disabled by default. Take a look at these for more info:

| We've been going over this in another thread that's still active on the front page. See Yanik's video tutorial for the basic explanation. |
