There are several
pages on the
Masters Of Imaging
website that
require a certain
size format to be
viewed correctly. |
Make your screen wide
enough to see both arrows on this line with a strip of
black at each end:
|
The image
below should appear as a rainbow starting and ending
with red. There should be a smooth transition from
color to color without banding and without little dots. |
-
The following
image is not a smooth transition.
-
If you have
only limited colors ( i.e. 16 levels of color)
-
the above
rainbow will look something
like this:
|
or
like this
Ok,
that's color, now let's deal with gamma, and contrast.
|
Below are
some boxes, one should be absolute black.
Nothing on your monitor should be darker than
the black box. Look at the black border around
your monitor. It should be as black as that box.
And nothing should be lighter than the white
box. The grey box and the white box should have
no tint to them. No pink or blue! in them. |
|
This is a
10 section step wedge to allow you to check that
you have a full chromatic scale available on your
monitor. You should be able and see the 10
separate tones going from an all white to a total
black.
Gamma (or contrast) is next.
Step back from your monitor.
One of these numbered boxes is about the same
shade as the surrounding.
|
|
That's
your "screen gamma." Most photographer's
web pages are designed for 1.8 Gamma. CTR Monitors
are calibrated for 2.2 Gamma.
