Pixels
After some consideration,
I realized that some of you may not know what a pixel is. I've been running
some tips about pixels lately and I forgot that some of you may not even
be familiar with the initial term. And although all of you are so smart
and you've probably been able to figure it out, I thought I should give
you a formal definition anyway. So, here it goes.
A pixel, which is
short for picture element (think the "pic" and "el"),
is one single point in a graphic image (or picture). Pixels are somewhat
made out of dots and squares and if an image is enlarged too much, those
may come out in the end result. That's typically not what one wants their
images to look like, so it's best to keep the pixel number set low. If
the number is right, those dots and squares will never show up in your
picture.
Pixels also range
in a variety of colors and each one has about three or four dimensions
of color, including red, green and blue, cyan, magenta, yellow and black.
So, whenever you're looking at an image on your computer or even your
desktop wallpaper, you're looking at a whole bunch of pixels. They help
your picture to look its very best. Cool, huh?!
