Re: SLT-A99V Color Contamination

Can you give a bit more info on what you are doing with the image?

Did you shoot RAW or JPEG?

Was any post processing done to the image?  If so, with what software and what did you do?

From what I am seeing it looks like you are getting posterization occurring in the shadows.  I am seeing it on the wall, in her hair, on her face, and all over her jacket.  I see this occur more when their is an attempt to extract more out of the image than what is there, poor image compression techniques, or through different kinds of post processing or filters being used.  There are a couple of other possibilities, but most that I have seen were due to post processing or the RAW converter being used.

Do you have a shot of the original, untouched, image that came directly from the camera?


Also, do you have any EXIF information from those shots that you can provide (ISO, shutter speed, etc.)?
