Custom Setting #E3 Flash Mode For Internal Flash - Nikon D300 Complete Manual

Recommendations:
1. I believe everyone should set at least 1/30. Nikon's 1/60
default is very conservative, and will cause problems in
most indoor lighting situations (for the reason why, read
the full flash section).
2. I personally set 1/15 because I know I can usually hand
hold the camera to that level when using flash as I
describe, and it's the slowest speed where subject motion
in the ambient exposure doesn't become a constant
problem (it may be a bit of a problem at 1/15, but I watch
for that).

Custom Setting #E3 Flash Mode for Internal Flash

(Flash cntrl for built-in flash)
I wish Nikon had set flash mode up differently (e.g. put the
flash mode control into the Flash Pop-up button in
conjunction with the command dials). Because buried down
in the Custom Settings menus, and requiring multiple settings
for some functions, partially negates a very useful feature.
Nikon needed a way to control what method the internal flash
uses when it's popped up, and this is where we set that. Just
be forewarned that this gets a little involved (especially if you
haven't read the flash section that starts on page <593> yet):
