Over the years I’ve needed to make simple illustrations for my blog posts, but I’ve been stymied by drawing simple circles. Looking up tutorials on how to do this in PhotoShop led me to confusing, weird, or just plain incorrect methods. However, I recently wanted to draw a circle for my post on the distance to the horizon, and decided to ask an expert: The Little Astronomer, who showed me how to do it in about 20 seconds. I wrote down what she said, and what the heck: if I post it here on the blog it’s there for me to reference, and maybe it’ll help you too.
For the record, I currently use Photoshop CS3 version 8 on a Mac running OS X 10.4. I don’t think that matters much though. If it does, leave a comment! And hey, comment if you know another method too. The more the merrier.
