I have a Droid smart phone. The phone is a year old HTC Hero, which I don't love performance-wise as it's always dropping calls -- and ALWAYS isn't hyperbole -- has the battery life of a newt, and is flaking paint from its buttons, but I do enjoy its "smartness" in terms of web, gps, email, etc.
Because it's not an iPhone, the Apps available are not nearly as plentiful and I haven't found many I really enjoy and/or find useful.
But I did find one that I really like. It's called Retro Camera, available here on AppBrain, and it is super-duper satisfying.
Just look a the scrumptious photos I took this afternoon at a traveling carnival set-up in the parking lot of the just recently no-longer functioning Wonderland Greyhound Track. (I used the "LITTLE ORANGE BOX" camera for these shots, but I'm not sure which real retro camera it mimics.)
The boys and I were on our way back from a sleepover at my mom's in cambridge, our dog lindsey was in the car, but we stopped so Tex could go on a ride. It was much nippier than I thought so we all had cold noses and fingers for the first time this year, and the dragon ride for kids was actually much faster than it looked before Tex got on it. Poor guy, when he rounded the corner the first time he looked severely apprehensive, the second time around, he was sobbing. They stopped the ride for him, he skittered off, flung himself into my arms and cried, "I wan't to go on a different ride"-- the kid's spirit is hard to crush!
The sun was just starting to set when I took these photos and I think they're very fun. Obviously, with the gunky edges, they are a bit gimmicky looking, but the colors are really something.
This is how a couple of the other "cameras" look:
Alternatively, I haven't tried the photo app Vignette, but it some positive reviews as well.
