There are many, many camera apps out there with filters and effects to make your snapshots look like they were taken with a 30 year-old Polaroid. Fewer are the camera apps with cool, well-thought-out filters that make for fun images. Paper Camera definitely fell into the latter category, and the follow-up Camera 2 looks even cooler.
Camera 2 has some typical hipster-type camera effects like lomo, but the majority of its filters are genuinely interesting. For instance, there are retro filters that make your images look like they're straight out of the 20's, 40's, 50's, 60's, 70's or 80's. Camera 2 also has comic, sci-fi, and computer filters.
The app supports filters for still images and videos, and the UI is super-smooth and flashy. Filters are selected right from the viewfinder, and shows live previews of what the resulting picture will look like. The way Camera 2 shows multiple live filter previews is super-neat. Additionally, you can cycle through the filters in each category by swiping left and right in the viewfinder (a very nice touch). At first glance, this looks like it's worth the asking price. But be aware video filters require a device with the NEON instruction set, which most modern phones and tablets have.
