Learn about techniques that allow the composition to be what you want it to be, and how you place the zone of focus between two different parts of the frame.
- Focus is an ethereal thing.…It's not a physical substance…that you can put your finger on.…It doesn't disappear all of a sudden.…It gradually deteriorates as you move away…from the critical point of focus.…Now, you have to find it in order to use it.…First, let's define the term Zone of Focus.…There are actually two zones of focus.…The Zone of Focus is the area in front of…and behind the lens which is acceptably sharp.…
Briefly, the area behind the lens is a concern…because it's a technical adjustment,…best left to trained technicians.…This is also one of the factors we consider…when we're picking a camera in the first place.…How stable is the zone of focus,…sometimes called collimation or back focus.…Now I don't want to get into too much depth.…Suffice it to say that part of the testing is determining…that the zone of focus places the image…at the plane of the sensor and that it stays there.…
Now, in front of the lens, we have what I'll call…the subject zone of focus.…So let's take a look…at a technique called a focus split…
