Further experiments with F/22 Bracketing

Had a chance tonight to play around with the F/22 Bracketing idea and came across the first problem: sensor dust etc.

That is, at F/22, of course, any dust on the sensor will be pretty clear.

Here is tonight's test image: this time taken with my Irix 11mm at F/22.

I took seven manual images between about 0.7m and 1m.

The sensor dust is clear on the wall.

Bottom line: this could be the end of the F/22 Bracketing idea :-(
