Back when I was in college I used to carry around and photograph with a Holga camera. It used 120mm film with 2 1/4" square frames...a hip, novelty, plastic camera with light leaking from random places. It was an art movement and I loved it. Digital photography (which I initially resisted) is returning to me that which I had lost in the shuffle of parenting. Using an application on my phone, I am having a Holga experience once again .
I call them pocket photos.
