Bluristic

Amazing long time exposure app with up to three tracking points.

It allows object tracking with a real time preview. This enables you to create a fantastic blur in the back and foreground by moving your iPhone / iPad slowly around your object. You can also track moving objects. With the latest App update you can now record first and track the objects later. This will be helpful when you have faster moving objects which you want to track.

You have three different Capture Modes:
-Blend
-Additive
-Negative
