Instagram is and app for the iPhone that has peaked my interest in photography. This app allows you to post any of you pictures for others to look at on your Tumblr, Facebook, Twitter, etc. Whether it’s a picture of your Lego collection or your new puppy Instagram lets you post it for people to “like” and/or “comment” on. Instagram also lets you share your pics with people on Facebook and Twitter. Also if your photo is liked enough it can make the popular list and be viewed by even more people. Other Instagram companion apps are Instapad, Instagallery, and Instamap which all are great on the iPad. Check out some of my Instagram photos on my Tumblr site here.
