We first adjust the
white balance to match the light we think is closest to the
ambient light – or the way we intend the final image to play
Then there’s the
challenge of determining a trial exposure. This is what gets
most people in trouble.
Any of the non-manual
modes will set up an exposure that moves the white snow toward a
middle tone – unless you play all kinds of gymnastics with
exposure compensation. There’s no fun in struggling through all
Working in manual, using
the spot meter, we can often find a middle tone nearby that is
lighted with the same quality of light. When this is the case,
we can use that reading to set up a trial exposure.
We make a trial exposure
and review it.
On our digital camera
backs, we see flashing when highlights lose detail (are blown
out). That’s the first thing we check. We know that in the RAW
mode we can recover some highlight detail that appears blown
out, but there’s no reason in a white on white image to force
that issue. (Note: in some compositions we might choose to
design the image with some highlight detail blown out.)
