Depth Of Field ( DOF) Workshop Lecture.

To start of the work shop we had a 45 minuet long Lecture about Depth of Field looking at the distance in front of and beyond the point of focus of the a subject and coving the basics of Depth of field, looking at the critical point of focus in front and a object behind appearing in focus.
In optics, particularly as it relates to film and photography, depth of field  is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions
In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus. The DOF is determined by the camera to subject distance, the lens focal length, the lens -F stops and the format or circle of confusion criterion. 

In the lecture we also looked at a few photographers like
Paolo Roversi
Peter Praser
Martin Par
Naoya Hatakeyama ( i think thats how you spell it)
so on so forth.


Here are some notes from the lesion.
