Canon EOS 7D, Sigma 150mmДЇ/2.8 macro,В 1.3 second exposure at ISO 200, f/9. This robber fly was shot at f/9, a medium aperture setting, and itвЂ™s notД®venВ close to being entirely in focus.

This inevitably means that depth of field is extremely shallow - so shallow that in many cases, most of the subject goes out of focus, even if itвЂ™s as tiny as a fly, and even if we close the aperture to f/16 or more. When doing macro work, we often shoot at 1:1 magnification or more, compelling us to be extremely close to the subject. The wider the aperture we shoot at, and the closer we get to the subject, the shallower the depth of field becomes. LED torches were used to light the subject and background, and I took this shot inВ La Fortuna, Costa Rica.ДЄs IвЂ™ve mentioned before, depth of field (DOF) depends almost entirely on two factors: aperture value and magnification. Its body is very deep and if shooting conventionally, I wouldnвЂ™t have been able to get all of the subjectвЂ™s interesting parts in focus.Д¬anon EOS 7D, Tamron 180mm f/3.5 macro lens, 2 shots both at 5 sec, ISO 400, f/16.

I couldnвЂ™t have gotten this red-eyed tree frog shot without use of a special image-combination technique. In the world of macro photography, as demonstrated in a previous article, things are entirely different. When we take portraits and wish to separate the subject from the background, we use bulky lenses with large apertures just to get that magical 3D effect we're striving for. In the world of photography we often work hard to obtain a shallow depth of field.
