:Developed by [https://twitter.com/mcflypg Pascal "Marty McFly" Gilcher], RTGI & '''Screen-Space''' Ray Traced Global Illumination is a shader for ReShade which make use of Path Tracing to bring Real Time Global Illumination to every gamesgame. Global Illumination is certainly not something new for games , but unlike conventional Baked / Precomputed Realtime GI, Marty McFly's Path Traced solution can provide a way more realistic and physically correct Global Illumination for every game.

:Games use a pinhole lens camera model to render their images. As such, they do not exhibit the same visual effects seen in real cameras, and effects exclusive to those have to be artificially reintroduced. A Depth of Field (or DOF) filter simulates the blurring of out-of-focus areas in the image. In a real camera, many factors influence the appearance of of the DOF blur, or so-called “Bokeh”, which photographers and film makers filmmakers use extensively as an artistic tool. This physical Depth of Field shader recreates this effect as faithfully as possible.

:Effects like unsharp mask are designed to sharpen or soften the image in a wider range, to enhance medium -sized details in the image and give the content some grip. The balanced, yet contrasty look of movie posters and magazine covers is quite often partially achieved through this effect. Much research is going into the type of filters that enhance local contrast, from the most basic unsharp mask to state of the art “Local Laplacian” filtering. Using this effect in realtime on video games allows to give blurry textures some bite, enhance the overall contrast of a scene or produce some pseudo Depth of Field effect to give the scene some depth. Clarity contains 2 different types of image enhancements, which can be used together.

::This add -on is ideally intended to be used with the Sony Megatron ReShade Port Presets.
