Small Aperture Setting As a novice in photography I've always thought that a smaller aperture compared to a larger aperture (say 22 vs 4.5) is supposed to result in more detail of your subject at different distances. I just shot several rolls of film at the Grand Canyon and used almost entirely small aperture settings in hopes of keeping detail at varying points. My results proved to be fuzzy or hazy rather than sharp. I used a tripod and no shutter speeds lower than 1/45. Am I missing something? Should I have used a more moderate aperture to give more focused detail? I'm very confused, please help me out.

Small apertures will increase depth of focus (apparent focus of objects both near and far), but not necessarily sharper images. On many/most lenses an aperture smaller than f/16 begins to lose sharpness due to diffraction. See the definition of diffraction at http://www.usa.canon.com/eflenses/lens101/glossary/index_d.html
