EdgeCam is a unique camera tool that uses edge detection and filters to create photos on your iOS device. The result is one of five different options that can greatly change how you see a specific image or event; and while the images themselves are not always clearly defined, they are an interesting addition to many photography app libraries.
When you open EdgeCam for the first time, the app will default to medium edge detection, showing the edges of every object in the room. This view can be disarming at first, but as you move the camera you'll see how the filter adapts. You can also change to low- or high-edge detection to get a more or less defined look and feel. Laplacian filtering offers more of a fill-oriented look and feel to your images while sepia is exactly as it sounds. These filters add a very different look to the images and they're well executed. The interface is stripped down enough to make snapping photos quick and easy, and there are not a lot of options to choose from. There is no settings menu, no lighting or filter adjustments, and no filtering for existing images in your photo library. Just choose a filter option and tap the screen to take a photo and save it to your library.
EdgeCam may not have a lot of features, but for those that want a free edge detection camera, this is a solid app that's easy to use.
