[7-05] f/16 v f/64?

Last week I started cracking my camera’s aperture to f/16.

Why not? It’s the smallest aperture.

At f16, we are looking f/1.4 -> 2^7 less light => 128 times less light than maximum.

f1.4

f2 => 1/2^1

f2.8 => 1/(2^2)

f4,5.6,8,11,16

The DOF increases significantly.

The f/64 group was about the same thing, and it turns out, for a 4x5” camera, a standard lens of 185mm, at f/64, as the same DOF as a 50mm on a 35mm camera at f/16.

Voila. We can join the f/16 club today.
