Introduction
to PhotoShop
Fill
out the photoshop worksheet
as your teacher goes over the tools and definitions.
For
this class you must know the tools below:
For
this class, you must memorize the following keyboard shortcuts:
Most of them are the same as the shortcuts for Microsoft Word
and most computer applications, so you may already know them.
Keyboard shortcuts will allow you to work much more efficiently.
All of these commands can be found PhotoShop's menus.
You
WILL have a quiz on these shortcuts

Most applications
allow you to change and create shortcuts for any commonly
used actions.
Save
an image from the web. The best way to do it is to right click
on it and choose "save picture as..." You probably
want to give it a name that you'll remember later.
ESPN
saved this image as "rpm_ap_stewart3_412". "Racecar
driver" might be a better name.
Save
this image in your folder on the G Drive as "racecardriver"
You
can also open an image in photoshop by right-clicking on it
and choosing "copy" and then opening a new document
(CTRL+N) and pasting the image into the new file (CTRL+P).
Be sure to save the image before manipulating it.
If
you're working with one image, always maximize the window
of the file. No sense in having a 17" monitor if you're
only going to use one quarter of it. Ever watch your parents
use a computer? I bet they never maximize their windows. Why
is that? If you have several images open, it may be useful
to keep them minimized.
The
first thing you need to know how to do is zoom into and image
and zoom out. There are several ways to do this:
Pressing
CTRL++ and CTRL+ - allows you to zoom in and zoom out of an
image. It defaults to the center of the image, which isn't
always the part of the image you want to look at.
The
slider on the bottom of the Navigator palette allows you to
zoom in or out of an image. The farthest you can zoom in is
16x or 1600%. This allows you to see small details of an image.
You can also type in a specific percentage on the bottom left
of the navigator palette. The red box shows you what part
of the image you are looking at. You can click on the red
box and move it.
The
zoom tool, or magnifying glass allows you to select the part
of the image you want to magnify. You can click and drag to
select a specific area. Hold the ALT key when using the zoom
tool to zoom out. When zoomed in, use the hand tool to grab
the image and move it. The spacebar on the
keyboard will allow you move around the canvas.
When
zoomed in you'll notice that the image is made up of little
squares of color. The squares are called pixels.
Images made of pixels are known as raster
images or bitmaps.
Think of a mosaic
(which can be made of small bits of paper, cloth, glass or
other media, or even tiny photographs.
Manipulating
these pixels is what PhotoShop is all about.
In
raster images, the computer encodes the location and color
of every pixel in the image. How many pixels are in the photo
of the racecar driver?
Choose
Image Size under the Image Menu.
Raster
images can be large, in terms of memory.
