Using selective focus on your Canon EF lenses. In issue No: 1, entitled "Introduction", EOS users and other photo enthusiasts alike were introduced to the fundamentals of photography and the three essential questions which a professional photographer always asks himself prior to clicking the shot. In issue No: 9 on "Composing and Framing", surfers were shown that the second essential question has a lot to do with the composition of the picture. One technique, which was not described in that issue, is the use of selective focus to portray the effect of the second question to the maximum. Yes, selective focus is related to the use of shallower depth-of-field in your photos. This technique is more effective with lenses having maximum apertures such as f/2.8, f/1.8 or larger and focal lengths from the standard 50mm all the way to 1200mm super telephoto! It is less effective with wide-angles, especially those having focal lengths of 24mm and below. Most EOS users and other photo enthusiasts alike already know that wide-angle lenses exaggerated perspective and an almost unlimited depth-of-field. Even when pictures are shot at the maximum apertures, the depth-of-field of wide-angle lenses is still deeper than what a standard 50mm or telephoto lens has, thus rendering the selective focus technique to an insignificant effect. As I have mentioned in issue No: 1 of "Introduction", the secret to professional photography is having the know-how of when to use and combine several fundamentals of photography in order to execute the desired effect. In this issue, more than 90 per cent of the photographs used here have appeared in my previous columns. The idea is to show how shallow focus has been utilized in addition to the other fundamentals of photography employed for the photos. << Back to Main . 1 . 2 . 3 . 4 . 5 . 6 . 7 .
