Thanks, George. It's my favourite too, though it doesn't seem to have received as much attention as the third one.
Since it's still extremely cold outside I haven't been able to experiment very much, given how long it takes to change settings. Changing "film", "lenses", and "flashes" seems to take almost as long as if it were a real camera. So I've just been using two settings, one for colour and one for mono.
The colour one comes with the app and is called Cinematic. You can find it in the Presets by tapping the three circles near the bottom right of the screen, holding the phone in landscape orientation.
The mono one I stole from someone else, in one of the photos submitted to Hipstamatic's What's New section, which you get to by tapping the Gallery icon at the far right then scrolling down. The photo is called Stranger (as is my new preset, strangely enough) and the settings are as follows - Lens: John S, Film: AO DLX, Flash: Apollo. Once you find the photo just tap the Install button at the bottom right. If you're missing any of the three elements, you'll be prompted to buy them.
