Photoshop is an incredibly powerful but also intimidating  application. If you've wanted to start using Photoshop but didn't know  where to start, we'll be teaching you the basics all week long.It's short considering  how much it covers and long considering it's on the internet. In the  video, we take a look at every tool in the toolbar, your palettes on the  right side of the screen, and what you'll find in the menus. Below  you'll find a reference for this lesson. Once the lessons are over,  we'll provide everything all in one place and a downloadable PDF file  containing references for each lesson.Wait! I don't have Photoshop!Are you not currently a Photoshop user? Adobe offers a Photoshop 30-day trial  that you can download right now and it will provide you with plenty of  time to learn how it works.
The move tool simply lets you move objects in a given layer around  the Photoshop canvas. To use it, click anywhere on the canvas and drag.  As you drag, the Photoshop layer will move with your mouse.
If you don't want to eventually purchase  Photoshop because it's too expensive, much of what we're going to  discuss in these lessons will apply to not just to Photoshop but pretty  much most of the standard photo-editing and design tools you'll find (Pixelmator is a great $30 alternative on the Mac, and GIMP  is a free, open-source cross-platform option). We've chosen Photoshop  because it's the most commonly used, but you're welcome to follow along  using other software as well. Today's lesson is pretty  Photoshop-specific, but as we move along you should be able to use other  software to do most of what we discuss.Ready? Let's get started.
The Toolbar
We're not going to take a look at every single tool but we are going to look at almost every one of them. While this overview will give you an idea of what each tool does, go find yourself a photo and start playing around with them.Move Tool (Keyboard: V)
The move tool simply lets you move objects in a given layer around  the Photoshop canvas. To use it, click anywhere on the canvas and drag.  As you drag, the Photoshop layer will move with your mouse.Marquee (Keyboard: M)
The marquee lets you select part of the canvas in a specific shape.  By default you get a rectangular (or perfect square if you hold down  shift while selecting), but you can also select in the shape of an  ellipse (or a perfect circle if you hold down shift while selecting). Lasso (Keyboard: L)
The lasso is a free-form selection tool that lets you drag around the  canvas and select anything the lasso'd area covers. Within this tool  you also have access to the polygonal lasso, which lets you create a  selection by clicking around on the canvas and creating points, and the  magnetic lasso, which works the same as the regular lasso but attempts  to detect edges for you and automatically snap to them. Magic Wand (Keyboard: W)
Clicking an area with the magic wand will tell Photoshop to select  the spot you clicked on and anything around it that's similar. This tool  can be used as a crude way to remove backgrounds from photos.Crop Tool (Keyboard: C)
The crop tool is used to (surprise!) crop your pictures. You can  specify the exact size and constrain the crop tool to those proportions,  or you can just crop to any size you please.Eyedropper (Keyboard: I)
The eyedropper tool lets you click on any part of the canvas and  sample the color at that exact point. The eyedropper will change your  foreground color to whatever color it sampled from the canvas.Healing Brush (Keyboard: J)
The healing brush lets you sample part of the photograph and use it  to paint over another part. Once you're finished, Photoshop will examine  surrounding areas and try to blend what you painted in with the rest of  the picture.
The paintbrush is a tool that emulates a paintbrush and the pencil is  a tool that emulates a pencil. The paintbrush, however, can be set to  many different kinds of brushes. You can paint with standard paintbrush  and airbrush styles, or even paint with leaves and other shapes as well.
Like the healing brush, the clone stamp lets you sample part of the  photograph and use it to paint over another part. With the clone stamp,  however, that's it. Photoshop doesn't do anything beyond painting one  area over a new area.
The history brush lets you paint back in time. Photoshop keeps track  of all the moves you make (well, 50 by default) and the history brush  lets you paint the past back into the current photo. Say you brightened  up the entire photo but you wanted to make a certain area look like it  did before you brightened it, you can take the history brush and paint  that area to bring back the previous darkness.
The paint can tool lets you fill in a specific area with the current  foreground color. The gradient tool will, by default, create a gradient  that blends the foreground and background tool (though you can load and  create preset gradients as well, some of which use than two colors).
All three of these tools act like paintbrushes, but each has a  different impact on your picture. The blur tool will blur the area where  you paint, the sharpen tool will sharpen it, and the smudge tool will  smudge the area all around the canvas. The smudge tool is very useful in  drawing for creating nicely blended colors or for creating wisps and  smoke that you can add to your photos.
The burn, dodge, and sponge tools are paintbrush-like tools that  manipulate light and color intensity. The burn tool can make areas in  your photo darker. The dodge tool can make them lighter. The sponge tool  can saturate or desaturate color in the area you paint with it. These  are all very useful tools for photo touch ups.
The pen tool is used for drawing vector graphics.  It can also be used to create paths that can be used for various things  that we'll discuss in a later lesson (although if you watch the video  you can see a type path being created).
The type tool lets you type horizontally. Tools hidden beneath the  horizontal type tool will let you type vertically and also create  horizontal and vertical text masks.
The shape tool lets you create vector rectangles, rounded rectangles,  circles, polygons, lines, and custom shapes. These tools are very  useful when designing or when creating shape masks for photos.
These are the 3D tools. We're not going to be dealing with 3D stuff  in these lessons so all you really need to know is that these exist. If  you're curious, this video will give you an idea of what these tools can do.
The hand tool allows you to click and drag around the Photoshop  canvas. If the entire canvas currently fits on the screen, this tool  won't do anything. This tool is for easily navigating around when you're  zoomed in, or a picture is simple too big to fit on the screen at 100%.
The zoom tool lets you zoom in and out of the Photoshop canvas by  clicking on a given area. By default, the zoom tool only zooms in. To  zoom out, hold down the option key and use the zoom tool as you normally  would.
These tools let you manage the colors you're using. The color on top  is the foreground color and the color in back is the background color.  The foreground color is what your brushes will use. The background color  is what will be used if you delete something from the background or  extend it (although now, Photoshop CS5 will give you the option for  using your foreground color instead in some circumstances). The two  smaller icons up top are shortcut functions. The left one, showing a  black square on a white square, will set your foreground and background  colors to the defaults (Keyboard: D). The double-headed curved arrow  will swap your foreground and background color (Keyboard: X). Clicking  on either the foreground or background color will bring up a color  picker so you can set them to precisely the color you want.
The layers palette lets you see all the layers in your document. As  you start getting to know Photoshop, you'll find yourself in this  palette more than any other. It'll let you organize and arrange your  layers, set blending modes,  set visibility and opacity of layers, group and merge layers, and a  bunch of other neat things we'll learn about in future lessons.
Your adjustments panel is where you can easily create and edit  adjustment layers. Adjustment layers are non-destructive image  alterations that affect all the layers below them and can easily be  turned on and off. Their most common use is for color correction (namely  the Levels and Curves adjustments, but there are many  different kinds of adjustments you can perform that can dramatically  alter the look of your image.
The color channels palette will let you look at the specific colors  that make up your picture. If you're in RGB mode you'll get red, green,  and blue. These color channels will differ if you're in a different  color space (such as CMYK or LAB).  When you choose a specific color, you'll notice you'll be shown your  image in different versions of black and white. This is because each  color channel is simply a monochromatic images representing the light in  each channel (e.g. the red channel is just a look at the red light in  your photo). Switching between these different channels is useful for  making color channel-specific touch ups, overall contrast enhancements,  and also for converting your photo to black and white in a compelling  way. This will be discussed in greater detail in a later lesson about  color correction and photo enhancements.
This palette will let you easily alter your foreground and background colors using sliders.
The color swatches palette is a set of pre-defined colors you can  quickly choose from. You can load in several other pre-made swatch  collections or create your own, too.
The history palette lets you go back in time to undo any previous  alterations. The standard undo command (in the edit menu) will simply  toggle between undoing and redoing the latest action performed on your  image. The history panel is where you can go back much further (50  actions by default).
The text palette, and the paragraph palette below it, let you make  all sorts of adjustments to any text you create with the type tool.  These options are very similar to what you'll find in a word processing,  but you can also specify things like character width and spacing which  are more useful in design.
Paintbrush and Pencil (Keyboard: B)
The paintbrush is a tool that emulates a paintbrush and the pencil is  a tool that emulates a pencil. The paintbrush, however, can be set to  many different kinds of brushes. You can paint with standard paintbrush  and airbrush styles, or even paint with leaves and other shapes as well.Clone Stamp (Keyboard: S)
Like the healing brush, the clone stamp lets you sample part of the  photograph and use it to paint over another part. With the clone stamp,  however, that's it. Photoshop doesn't do anything beyond painting one  area over a new area.History Brush (Keyboard: Y)
The history brush lets you paint back in time. Photoshop keeps track  of all the moves you make (well, 50 by default) and the history brush  lets you paint the past back into the current photo. Say you brightened  up the entire photo but you wanted to make a certain area look like it  did before you brightened it, you can take the history brush and paint  that area to bring back the previous darkness.Eraser Tool (Keyboard: E)
Paint Can and Gradient Tools (Keyboard: G)
The paint can tool lets you fill in a specific area with the current  foreground color. The gradient tool will, by default, create a gradient  that blends the foreground and background tool (though you can load and  create preset gradients as well, some of which use than two colors).Blur, Sharpen, and Smudge Tools (Keyboard: None)

These tools let you manage the colors you're using. The color on top  is the foreground color and the color in back is the background color.  The foreground color is what your brushes will use. The background color  is what will be used if you delete something from the background or  extend it (although now, Photoshop CS5 will give you the option for  using your foreground color instead in some circumstances).

Palettes are the things that you see sitting over on the right side of your screen. They make it easy for you to navigate through your document, add adjustments, switch modes, and other things.Layers
The layers palette lets you see all the layers in your document. As  you start getting to know Photoshop, you'll find yourself in this  palette more than any other. It'll let you organize and arrange your  layers, set blending modes,  set visibility and opacity of layers, group and merge layers, and a  bunch of other neat things we'll learn about in future lessons.Adjustments
