Without seeing any examples, I'm thinking what Quinn says above. Easiest way to tell would be to look at the Histogram of one of your images. If the data stretches across the entire histogram and clips against the left and right sides, then you're running up against the exposure latitude of your camera. If it just bunches up against the right side of the Histogram, then you are overexposing (clipping the highlights) and you should dial back a little when you shoot. I'm thinking it's the latitude, since you don't mention any other parts of your image being off. -=>Donald
