1/12
Histograms are graphs that count how many
pixels are at each level between black & white
Black (darker) is going left, white (lighter) isgoing right
Height of graph at each point depends on how
many pixels are that bright.
Can help you learn how many stops up or down
should be used for optimum exposure

-2 Stops Underexposure
Even the whitest
whites (thediamond rings &
bracelet) are
medium gray. No
shadow detail
desired for this
pose, so no loss
there, but
blacks/browns
need distinguishing.

-1 Stop Underexposure
Some very smallhighlights are
reaching towards
white. Skin has
emerged with its
myriad of tones,and the hand and
arms no longer
have a one-
dimensional look.

Normal Exposure
Pixels are where
they should be: closeto white, but not
clipped. The humps
indicate that values
are spread around a
bit, meaning there isdetail and not a flat,
washed-out
snapshot. More
exposure would be
okay in this case.

+1 Stop Overexposure
Overexposure
took away the linedetails in the
fingers and showed
additional flaws in
the object surface.If the backdrop of
the hands was
lighter in color, it
would produce a
high key effect.

+2 Stop Overexposure
Overexposed so
that there are aton of pixels blown
out to 100% white.
As you overexpose
more & more, the
graph moves
further to the right
& eventually clips
as your image
destroys itself.

How Full Is Your Cup ??
Consider this analogy: Water is the amount of light that you
allow to pour into your camera during an exposure. You can
adjust the rate of flow from the big bucket of light, but you can
also utilize your digitalized histogram to help guide you as well.

I changed hues & increased
blacks/contrast plus sharpen
