"At the very least, your monitor should be able to display
a full range of tones..."
What is it? Simply, it means your monitor brightness and contrast
controls are adjusted properly. That's properly, like, it
doesn't melt your eyes when viewed for more than fifteen minutes,
and, it displays a full range of grayscale tones.
It gets quite a bit more complex for digital artists, or for anyone
with need to match tone and color on a monitor for output by a print
device, but that is a subject for another day. At the very least,
your monitor should be able to display a full range of tones, and
this is very simple for anyone to do.
Below is the A&T New World Grayscale Calibrator. This
table evenly divides the entire tonal range between white and black.
There are fifteen shades of gray, plus white and black. You should
be able to clearly identify each of the fifteen shades. If so,
congratulations, you're calibrated. If not, you might try adjusting
brightness and contrast controls until you have the best display
possible for your monitor.
"The beauty of tables is that they give us a fair bit of
control over formatting and background color..."
HTML tables -- they're widely supported, all recent browsers I
am aware of, and they are easy to use. Here is the code used
to create each of the grayscale bars in the A&T New World
<FONT color=#0000FF size=1>
That's it. This code creates a table 90% of the width of the screen
(or the frame in this case) with a light gray background and text
"#C0C0C0" at left. Additional coding provides more control
over text color, size, and style. Very straight forward.
The beauty of tables is that they give us a fair bit of control
over formatting and background color, above and beyond the global
formatting for the whole page, and they're bandwidth friendly
in that they don't require repeated loading and transmission of
