As much as I love analogue photography, I also enjoy taking pictures with my smartphone. It just comes in handy: You always have it with you and you can’t worry about different settings. Just point and shoot (and play with different apps afterwards).
I really like Mextures, great app with a lot of different filters. But not available for Android – that sucks! Good thing is, my employer gave me an iPhone. Anyway, Mextures for my Samsung Galaxy would be great.
