| The diagram shows angle of view or angle of acceptance. |
I
have been looking back through my college notes and came across this
series of pictures. I used the colour film you find in the pound/
budget shops. I have had no problems with the way the film has
performed.
These
pictures show how much of the view in front of the lens is depicted
at the negative. As the focal length of the lens increases the angle
of view reduces but the object size gets bigger. Therefore as you go
up the focal range so the depth of field lessens.
