[QUOTE="480sparky, post: 738999, member: 15805"] The camera doesn't see the dynamic range of the scene. It sees the overall brightness of the scene. My histogram viewer put the median brightness of the images pixels at 105.9 (on a scale of 0-255). Which is slightly below(darker) than the middle of the scale (127). I copied your shot into an editor, desaturated it and started blurring it repeatedly. Once all the pixels ended up the same shade of gray, I measured them. They all came out as 106:106:106. Which is exactly what one would expect. The trick here is to know the limitations of your camera. A scene that exceeds the dynamic range it is capable of recording with have blown-out highlights and/or shadows that are pure black. It then becomes a matter of whether you attempt an HDR set of images and combine them in post (not always possible due to subject movement), or decide whether it's better to get details in the shadows and let the highlight blow out or keep the details in the highlights and let the shadows go black.
