For the HDR (High Dynamic Range) technique to work, you have to “shoot for HDR”
(in other words, you have to set up your camera to shoot exposure-bracketed shots
that can be used by Photoshop to create an HDR image). Here, I'm going to show
you how to set up both Nikon and Canon cameras (the two most popular DSLR
brands) to shoot three- and five-stop brackets, so all you have to do is hold the
shutter button and your camera will do the rest.
Your Camera
to Shoot HDR
Setting Up
Step One:
When you're shooting for HDR, you're
going to be shooting multiple shots of
the exact same scene (at different expo-
sures), and since these images need to
be perfectly aligned with one another,
you really need to be shooting on a tripod.
Now, that being said, Photoshop does
have an Auto-Align feature that does an
amazingly good job, so if you don't have
a tripod, or you're in a situation where you
can't use one, you can try hand-holding—
just make sure you're shooting in a well-lit
area, so your shutter speed will be fast
enough that your images won't be blurry.
Step Two:
We'll need to vary our exposure as we
take each HDR shot, but we can't vary
the f-stop or our depth of field will change
from shot to shot, so instead we vary our
shutter speed (actually, the camera will
do this for us). So, switch your camera to
Aperture Priority mode (the A mode on
Nikon cameras, like a D300S, D700, D3S,
D3X, and D4, and the Av mode on Canon
cameras like the 60D, 60Da, 7D, 5D Mark
III, 1D Mark IV, etc.). In Aperture Priority
mode, we choose an aperture (like f/8 or
f/11 for outdoor shots), and then the
camera will vary the shutter speed for us.
