Six correct exposures

When ISO speed is fixed, digital camera has at least six correct exposures that produce identical photo images theoretically.

To take clear and sharp photo without tripod and remote trigger, I put my camera on a box, mirror lock up is on, set the self-timer at two seconds.

The six correct exposures I experimented in my room under fluorescent light is below.

Aperture(f/#) Shutter speed (1/# second) ISO 1600
4.5 125(I made a mistake. It should be 4.0.)
5.6 80
8.0 40
11.0 20
16.0 10
22.0 5

f/4.5, 1/125s

f/5.6, 1/80s

f/8.0, 1/40s

f/11.0, 1/20s

f/16.0, 1/10s

f/22.0, 1/5s

Below two files contain EXIF data.
