✨ In real life, photographers use Neutral Density filters to prevent overexposure. In ReShade, use the Exposure or Tonemap shader to darken the scene before applying the blur to keep your whites from "blowing out."
ReShade can approximate long exposure photography but is fundamentally limited by lack of access to game engine motion vectors and the recursive nature of frame blending. For static camera + moving objects, manual accumulation works adequately. For realistic light trails, a game engine with explicit motion vector support is superior. However, ReShade remains the only tool for live long exposure simulation in unmodified commercial games. reshade long exposure
To successfully use this effect, specific setup steps are recommended: ✨ In real life, photographers use Neutral Density
This effect is computationally heavy. It requires the GPU to sample previous frames to build the exposure trail. If you experience low FPS, lower the Quality or Samples setting within the shader options. For realistic light trails, a game engine with
: For best results, use a replay editor (like the Rockstar Editor in FiveM/GTA V) or an in-game slow-motion mod. This allows ReShade more time to "sample" frames, resulting in a smoother blur . 2. Step-by-Step Setup
