Photography 201
Introduction
This is my follow-up article on the basics of photography. I have been an recreational photographer for most of my life and with the growing accessibility of digital photography I thought it would be the perfect time to share some knowledge. In this installment I would like to introduce several different types of photography. Each of these topics could be a post in itself but I hope this introduction peeks your interest and you search out and try any or all of the styles described below.
Macro
The classical definition is that the image projected on the “film plane” (i.e., film or a digital sensor) is close to the same size as the subject. Most 35mm format macro lenses achieve at least 1:2, that is to say, the image on the film is 1/2 the size of the object being photographed. Another important distinction is that lenses designed for macro are usually at their sharpest at macro focus distances and are not quite as sharp at other focus distances.
Limited depth of field is an important consideration in macro photography. This makes it essential to focus critically on the most important part of the subject, as elements that are even a millimetre closer or farther from the focal plane might be noticeably blurry.
