Creating Monochrome Images with
Your Color Camera Back
You can use your color camera back to create monochrome images. To
do so, begin by exposing as you would for a color capture. There are then
two methods you can use: convert to gray scale, and green channel.
Convert to gray scale. This is the preferred method, for it offers the best
tonal rendition of the image, and should be used with color images that
do not have high gain or noise levels. (High noise levels in images can be
caused for a variety of reasons, for example by extended exposure times.)
To use this method, click C
OLOR
C
ORRECT
“on” in the driver, and acquire
the image normally. Then choose G
RAY
S
CALE
from the Photoshop M
ODE
menu to discard the color information. You are left with the monochrome
image.
Green channel.
Use this method for color images that contain high noise
levels. (High noise levels in images can be caused for a variety of reasons,
for example by extended exposure times.) To use this method, click C
OLOR
C
ORRECT
“off” in the driver, set B
ALANCE
to N
ONE
in the driver, and then
acquire the image. In Photoshop 2.5 and later, choose G
REEN
from the
C
HANNELS
palette menu. In earlier versions of Photoshop choose S
PLIT
C
HANNELS
from the M
ODE
menu and work only with the data from the
green plane.
These actions produce a sharper image than reducing the other color
levels to zero, since half of the pixels in the imager are green. As a result,
the green plane has the most information when images are acquired in
Photoshop.
