Reco on Android DOF calculator for D800? And Coc vallue?
10 months ago

In this thread in the attempt to better understand my soft focus problem with D800, Per Baekgaard brought up a good point that CoC of D800 is different than typical camera.

This article by George Douvos has a good calculation and defined CoC for D800 should be 10 microns.  Do you agree that this is the right value?

"The Nikon D800 is blessed with a 35.9 x 24 mm, 7360 x 4912 pixel sensor. It thus packs 7360 pixels into 35.9 mm (and 4912 pixels into 24 mm). That makes 205 pixels per mm. And that makes each pixel about 5 microns in size.

At best, the smallest detail that a sensor can resolve spans the width of at least two pixels. So the D800 should be able to resolve image detail as small as 10 microns or so.*"

Also, the article pointed to an Iphone app TrueDoF-Pro

that allow users to input their custom CoC value.  Do you have any reco for similiar Android app?
