There are as many interpretations of how an image can be conveyed as
there are number combinations within the tool. Create several dif erent
interpretations and decide which one you prefer the best!

Note:
A close approximation to
the luminosity perceived
by the human eye
would be settings of
red 30%, green 59%
and blue 11%. An
approximation to the
default grayscale mode
change might be
red 60%, green 30%
and blue 0%, and
a mix of red 34%,
green 33% and
blue 33% is the
approximate equivalent
to desaturation.

Digital like i lm
For some digital photographers, the ultimate goal is to create black and white
digital images that look as if they were captured on i lm. The gritty quality
that came from pushed Kodak Tri-X i lm sometimes seems aesthetically so far
removed from the crisp digital i les we see with today's high resolution cameras.
There is a unique elegance in i lm's simple grain and mysterious qualities. For
the i lm photographer, certain specialized looks have always been achieved
by choices in chemistry, paper and technique coupled with the type of i lm or
emulsion chosen. The varying dif erences in the consistency of light sensitivity
in emulsions typically give each type of i lm its unique aesthetic. With many
i lms being taken of the market today, it is still incredibly useful to keep those
traditional names and what they meant to the i lm photographer alive, and use
them as points of reference. For the black and white photographer, whether
traditional or digital, using black and white ef ectively is about choosing a
“look” that matches your image and intention.

Of course, you will still have to add noise and grain to achieve the “look” of
some i lms.
