John Novak, one of our members, made a presentation last Wednesday on Lenses and their contribution to the composition of a picture. He suggested we learn how different lenses affect of photos. For example, the telephoto lens appears to compress the distance between objects due to the perspective from the more distant location. For a given subject distance, a telephoto lens captures the scene with a much shallower depth of field than does other lenses.

Thanks to John for his efforts. The information is extremely useful for those who can change lenses and even helps with decisions when to zoom or not with a point and shoot camera.
