Make Your Own Holiday Cards with GIMP
It's the holiday season! And it's a good time to connect with relatives and absent friends. Maybe you can send them some cards! But those packaged cards ... so drab, so dull. Wouldn't it be more fun to make your own? GIMP is a great tool for that.
Start With a High-resolution Photo
Pick a photo you like. It's important to have enough resolution, and that's an easy place to go wrong. People show up all the time on GIMP channels saying "I created my image as 5" by 7", but when I printed it out, it looks really fuzzy. What's wrong?"
What's wrong is that digital images aren't measured in inches -- they're made up of tiny dots called pixels. The number of pixels in an image controls how much detail you'll get when you print it. A common rule of thumb: if you want a good looking photo, try for at least 300 pixels per inch (PPI).
