I use Camera RAW 6.0 for RAW conversions and edit with CS5. When I upload a picture to Flickr or resize it with an outside program my pictures come out looking desaturated. Mainly losing red. CS5 is set to sRGB. If I open the picture in CS5 again, it still is missing the colour. This tells me that there is information being lost, not just being displayed differently.
I am not really great at figuring this kind of stuff out. I would like a way to keep the colours the way they are supposed to be.
Example of the colour differences:
The two resized pictures have lost the colour, the other two are fine.
