    Nice article. Just wanted to add that the aperture value also effects the depth-of-field. For example the same shot with f 8 will have a much shallower depth-of-field at 500mm than at 35mm, even though they will be equally lit. Depth-of-field is in itself a pretty big topic to discuss, may be another article.

      You bet DOF is a pretty big topic to discuss. I have a few articles planned; mostly on topics that I think will make it easier for digital photography enthusiasts to understand the photography basics and get better images.

      In fact, the Aperture value keeping the light same was a terrific revelation to me and I cannot wait to try out some standard scenes with a range of apertures to develop the mental idea of what aperture works best for a specific scene.

      Of course there are other factors – ISO, Shutter speed, DOF that will affect the composition and image quality, but now there is at-least a starting point – One constant, rest being variables.
