This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field Yesterday, we looked at object field MTF50 behavior with the lens focused at infinity, and found that with our simulated top drawer 55mm lens, a simulated… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field A few days ago, I gave a brief introduction to object field techniques for controlling DOF, then went on to other image plane oriented things. In… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field When I made this post, I said that the story of exactly how the curves were generated was to complicated to be included. I will now… [Read More]

This is a continuation of a report on new ways to look at depth of field. The series starts here: A new way to look at depth of field For the past few posts, I’ve been developing the concept of a hyperfocal distance based on the allowable degradation of image resolution as measured by MTF50…. [Read More]
