Custom Setting #B2 Exposure Control Increment
(EV steps for exposure control)
Exposure settings (apertures, shutter speeds, and bracketing,
but not exposure compensation
) that the D300 uses can be set
in three different increments. The increment chosen with this
setting is used for all exposure settings in the camera:
1/3 step
1/3
stop
increments
[default]
1/2 step
1/2
stop
increments
1 step
full stop increments
Recommendations:
1. It really doesn’t make much sense to set the alternative
values
unless
you are simultaneously shooting with
another camera body that doesn’t support 1/3-stop
increments (i.e. you want exposure settings to match
between both cameras). If you set 1/2-stop increments, for
instance, you could find yourself in situations where
you’re underexposing more than necessary to preserve
highlight detail. Generally you want to set your brightest
point as close to the top end of the D300’s range as
possible, and 1/3-stop increments allow you to get closer
to the top end than 1/2 stop increments
127
.
2. Note that this only controls the apertures, shutter speeds,
and bracketing steps that can be set. Exposure
compensation settings are set by Custom Setting #B3 and
127
Technically, we’re talking about a 1/6 stop difference. But every little bit helps.
