I’ve been playing a lot these days with Instagram, the popular photo sharing program recently acquired by Facebook. I’m usually not one for gimmicky iPhone apps, but I must say that I enjoy exploring what I can do using one of Instagram’s 16 digital filters. Best of all, the app is free and makes it easy to share pics and follow other photographers. Here are some of my favorite photos that I have taken with Instagram.
