I think this is a good idea
I think Popular Photography had something smilar
Here's some of mine
c.fn #2 is set to
on for noise reduction
c.fn #4 is set to
0 which is default I think but I use this a lot
I meter the shot with my thumb then autofocus with my index finger and take the shot
c.fn #8 is
on so I can use iso 3200
c.fn #12
enable mirror lockup for nightshots
I usually set the camera to timer then it's a shorter wait for the 20d to trip the shutter
No real secrets here but its a start
What's your settings ?
Thanks
Fred
