Disappointing

First off, it seems a lot of the earlier reviewers didnt quite understand the concept of this app: Its an iOS recreation of the Lomography Action-Sampler style of film camera. Google for examples from that to see why this app exists. You can also take strips of 4 images in the style of old coin-operated photo booths.

There is a pretty ridiculous bug where the first two images of 4 are taken much closer together in time than the third and fourth. Images 1 and 2 are essentially identical unless the delay timer is set much higher than the default. Also the shutter sound effect doesnt seem to sync with when the images are really taken. You can confirm this bug pretty easily by photographing the second hand of a clock.

The word "Shadow" in the settings is confusing. This doesnt mean a shadow around the finished image: it means corner darkening added to each image (in other words the "on" setting emulates lens vignetting).
