Have you ever looked at a product on the supermarket shelf and thought to yourself, "that is a cool font." No? Well, maybe you don't look at packaging as closely as I do. Anyway, fonts are an integral part of any product label and learning more about them will give you a better eye for good design.
There is an easy way to find out what font is being used. The popular font site myfonts.com has a new tool called What the Font. The way it works is you upload an image or point the site to a URL and it will tell you the name of the font.
But that doesn't help if you are away from your computer. Now, they have just released an iPhone application for What the Font. I downloaded it recently and have been playing around with it. It is pretty cool. When you launch the application it takes you to the iPhone's camera function where you take a photo of the type you want identified. You draw a box around the appropriate text with your finger and then it will search its database of fonts to come up with a match.
The photo above shows you the application in action. It has just identified some test text I created with the Rockwell font. It was able to easily identify this font giving several different variations. After playing with this application for a while I need to warn you it is certainly not foolproof. A couple of times it identified fonts that were close but not the exact font. Still, it is a useful tool for anyone interested in learning more about fonts and design.
