Hi,

I'm intrigued and puzzled by a color profile problem.
I work in photoshop CS4, color space adobe sRGB IEC1966- 2.1. Color profile embedded when saving.
Skin tones are perfect in photoshop, i do not push saturation etc, try to keep is natural as possible.
However after upload the images on-line appear to be pinkish... very unnatural skin tones. Below an example (screen captures with on the left how it appears online, on the right how it shows in photoshop)


Is there a setting i need to change to match the colors.?..

Patrick H.

ps : i'm working on a HP LP2475 w s-ips screen calibrated on a weekly basis with the panthone Huey pro.

Strange you should mention it.  I seem to have the opposite problem - my images look nice and saturated in PS and on my computer, but when uploaded the thumbnails on some of the sites seem to be undersaturated or have a slight cool tone to them. 

Since I am viewing it all on the same monitor I have just concluded that the thumbnail generators on some of the sites are responsible for the discrepancy.

Strange indeed... ??? Could be they don't read the embedded color profile.?..

Patrick, I'm working on the very same model of monitor that you are (love it!).  I calibrate it with a Pantone EyeOne Display2. I work in 16-bit, ProPhoto RGB colorspace, but convert to 8-bit sRGB before uploading. Oops. That's no longer true. I used to do that; now I send adobe RGB to everyone.

What I've noticed is, different sites do different things to the thumbs. Many add saturation, some change the tone slightly, add contrast. I've just given up trying to figure out how to make the thumbs look "right", and just UL what looks good to me and don't worry about it.

But, then again, my sales have been dropping lately, so maybe that's to blame?  ;D

Great screen indeed...  ;D

Some more info.. the problem is not only with the tumbs, i downloaded one of my own images from a stock site... and it shows the wrong colors too in a generic image viewer, however when i load it into photoshop the colors are again correct.....  ???

Another mystery of this business. Maybe that's why I get quite a few "incorrect white balance" rejections even though I'm certain the white balance is correct. ??

I work in Adobe RGB 1998 and submit them as such. I'm sure that the sites all do different conversions. It may be if you are embedding sRGB ... and then the sites also assign sRGB,  it may be doubling the sRGB effects. Those effects to my eye add saturation, mostly in the reds.

I've noticed that with my small point and shoot Canon that is only sRGB, images look much redder when opening directly into PS (not with RAW) than do images from my RGB 1998-set Mark III ds.  

If I have PS open jpgs in RAW, RAW converts jpgs from the point-shoot Canon sRGB back to RGB 1998, thus losing the camera-generated saturation of sRGB. At least that's my experience.
