Step 1: Step One: Are You Prepared?
Before you can start your animation, you must ask yourself a few simple questions:
Do I have hands to hold a mouse or pen to draw with? If you answered yes, you may continue.
Do I have a computer, and does it have Photoshop on it? If you answered yes, you may continue (but I'll take this time to say that the instructions I give you may not work for all types of Photoshop, I'll only tell you how to do it in CS5, but the procedure is similar is other types)
AND MOST IMPORTANTLY: Do I have a desire to animate? If you answered yes, you may continue, but first let me tell you why this is the most important. Animation is a long a tedious process, but the end result is worth it. If you aren't driven to finish a project, it may never see the light of day. Don't get frustrated or discouraged, everyone started somewhere, and once you get the hang of it, it's really more fun than work.
Congratulations, if you've made it this far, you are ready to animate, let's get going then, I'll just show you what you need to open.
Step 1.5 : Opening a New Animation:
Opening a new animation is just like opening a regular photoshop document. All you have to do is open Photoshop and go to File>New, or hold Ctrl+N. This will open a menu that asks you what you'd like your new document to look like. In the width and height boxes I usually put in 8x8 by typing 8 in both spaces and changing the drop boxes parallel to 'inches'. I also change the resolution to 300 pixels/inch. This makes the image less blurry and I can do more detailed work. When I change the animation into a GIF at the end, the resolution will go back down to 72px/inch, so you can leave it if you prefer.
