the answedepends ,of course, on what one is used to or used to work with.from my long-time experience and love with f-stoptiming


]iwould only consider the folloing:
1. 1/3 stop for rough test strips and significant changes in exposure
2.1/6 stop for closing-in test strips and clear changes in exposure
3.1/12 for fine-tuningtest strips and slight changes in exposure
finer increments might be useful for hard paper grades, but I 'd stay away from1/4,1/8,1/16 an so onand stick to 1/3as used on LFlenses
alsi important is the starting point.I recommend a base of 16s and work up and down from there. How do you intent to handle dodging and burning?
