Frischluft Lenscare AE is a set of camera-blur effects for After Effects and Premiere Pro. It uses physically-based algorithms that blur pixels according to their depth value, so 3D footage can take on high-quality camera blurs during 2D post-processing rather than through the longer render times of a 3D application.
The plugin includes two main effects. Depth of Field generates depth-of-field as a post-process and uses a depth buffer for its calculations. Out of Focus is a faster blur with a constant radius across the whole image; it supports a custom-drawn lens alongside the generated ones and adds background distortion for semi-transparent areas. Both offer lens aperture controls to simulate different cameras, with the aperture form most apparent in highlights, plus a brightness boost for selected out-of-focus areas.
Because focus is handled in post, various focus settings can be tested without re-rendering the whole scene. Version 1.5 moved to a new code base, and the plugin supports multi-frame rendering and Apple Silicon while running on both Mac and Windows.
