Tip #98. You can use an image to create your own brushes. They can be up to 2500 pixels x 2500 pixels in size. That’s pretty darned big. First, use whatever selection tool(s) you need to select what you want to use for your brush. Then go to Edit | Define Brush Preset and give your brush a name. It will append itself to the end of the list of brushes and when you hover your cursor over it, the name you entered will show up. The number included in the brush presets isn’t a count BTW, it is the size of the brush in pixels.
Tip #99. While Photoshop will remember your brushes, they aren’t really saved until they are saved into an .abr file. Use the preset manager to save the brushes you create. The process is just like saving styles, but you are saving brushes.
Tip #100. If your drive were to die tomorrow how much data would you lose? The only correct answer is, “none.” If you don’t have an effective back up system in place, it is time for you to spend money and get one. If you can afford a computer and Photoshop, you can afford to have a good backup system. I do not depend on an additional external hard drive. I use an on-line backup system. And I check it regularly to make sure that the data that I want to be saved has been included in the backup. It is not the responsibility of the service I select to tell me that my important files are backed up. Only I know what is important to me, so it is my responsibility to check.
