I have a question or two about the tonality of my prints. When I'm shooting anything with a lot of sky, the sky always appears uneven in its tone, despite the fact that it appears consistent to the eye. Is this just a difference between what my eyes see and what the camera sees? The reason that I ask is that it often appears to lighten when it's next to a darker object/tone. Is this a characteristic of film in general? It doesn't seem to happen in my non-landscape shots. I have attached an example, though it's hard to see exactly what I'm talking about. 35mm Tri-X in DDX. Straight print with no dodging or burning, but cropped to square. http://www.flickr.com/photos/71163977@N00/510294056/ Thanks.
