iOS: One of the drawbacks of using the video camera on your phone is the complete lack of control. While good automatic settings are useful in a lot of situations, there are times when they fail to achieve the look you want. While our expectations are fairly low for these tiny cameras, they don't have to be. CinePro supercharges your iPhone's video recording capabilities, providing everything from manual controls to fancy filters.
CinePro offers a lot of cool features. To start, you can set the frame rate, white balance mode, exposure, autofocus mode, and ISO. You can leave certain settings on auto and others on manual. The entire top row provides you with quick access to all the changes you can make. On the bottom row, however, you can choose filters and even make adjustments to them. CinePro includes several stock filters to start you off, but allows you to add more for $1 per pack (as an in-app purchase). Even if you don't go crazy with all the filter packs, the $1 it'll cost you to just get the standard app is worthwhile if you want a little more control over your video recordings. It's not going to turn your iPhone into a true cinema camera, but it's a great step in the right direction.
