DOF Calculator: Focus distance in logarithmic steps #337

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The current implementation of the DOF calculator allows for setting the focus 
distance as an integer number of meters only.

This works well in the range of say 3 to 10 meters. But for shorter distances 
it is far too coarse (DOF with most focal lengths changes drastically between 1 
and 2 meters), and for longer distances it is far too fine.

Hence I'd propose the use of logarithmic steps for focus distance. After all us 
photographers are pretty much used to log scales.

Something like 0.5 / 0.63 / 0.8 / 1 / 1.25 / 1.6 / 2 / 2.5 / 3.2 / 4 / 5 / 6.3 
/ 8 / 10 and so forth.
