There seems to be all kinds of photo filtering apps flooding the app stores lately, each one striving to be better than the next. The latest to hit BlackBerry App World is the free app Photo Filters. Unlike some others, Photo Filters only offers filters off the bat (not any editing features) but you can purchase additional features if you want more. The free app includes Alien, Black & White, Exposure, Gain and others. If you choose to you can purchase an additional 16 filters to max out the app's capabilities. Photo Filters is a pretty cool app if you're looking to stick strictly with filters, but there are other photo apps with various features so take a look and see which one fits you best.
