the spreadsheets has been tremendously helpful for me to learn my D200. However, over the time of trial and errors, I find personally I have some settings that I convert to my liking.
when you set up your custom settings A, B, C, D (each with unique name) can you somehow "lock" those settings in , just like locking in the .. (forgot the name, don't have camera on hand) custom menu selection?
I find myself deviate from my settings as I shoot and encounter different situation. By the end of the shoot I would have to get the spread sheets out and re-confirm my original set-ups.
