[QUOTE="WayneF, post: 367709, member: 12496"] You really want exposures to only the nearest full stop precision? Each exposure could be off up to 1/2 stop? Just set it to 1/3 stop. I pity the poor photographer who can't even remember those seven numbers. :) I was thinking, like, those numbers are on every lens. But I guess they are not anymore. :) All that seems obvious, but the very best tip is if you meter your flashes with an incident meter, set it to 1/10 stops. Then it reads like f/8 plus 0.7 stop or f/5.6 plus 0.2 stop. Then you can trivially know the difference in your head (obviously 1.5 stop here). And this bypasses the issue that what we round off and call f/11 is technically f/11.3, which matters in calculations. [/QUOTE]
