Mastering the Art of ReShade Long Exposure: A Complete Guide to Creating Silky Water and Light Trails Without Post-Processing

In the world of video game photography and realism modding, achieving the perfect “dreamy” aesthetic often feels like a battle between real-time rendering and post-processing software. We all love those stunning screenshots on Flickr or Reddit showing waterfalls that look like silk, city streets streaked with light trails, or oceans that look like frosted glass.

The natural assumption is that these artists took the screenshots and blended them in Photoshop. But what if you could achieve truly realistic long exposure effects while still actively playing the game?

Enter ReShade Long Exposure—a powerful, often misunderstood technique that uses shader injection to simulate the effects of a camera’s slow shutter speed. This guide will explain the science, the setup, the best shaders, and the step-by-step workflow to master long exposure effects in any PC game.

Method B: The "Shutter Drag" (Motion Blur Amplified)

Best for: Racing games, high-speed action, "Spiderverse" comic effects. reshade long exposure

This uses qUINT_motionblur.fx but tuned to extreme values.

How to configure it:

  1. Disable the game's native motion blur.
  2. Enable qUINT_motionblur in the standard "Home" effects tab.
  3. Samples: Set to 32 or 64 (higher = smoother, but costs FPS).
  4. Shutter Speed: Set to 1.0 or higher (Default is usually 0.2). This artificially tells ReShade the shutter was open for a full second.
  5. Blur Strength: 0.75 - 1.0.

Unlike Method A, this only blurs objects moving relative to the camera. If you pan the camera quickly while a car is static, the background blurs. If the car moves across a static screen, the car blurs. Mastering the Art of ReShade Long Exposure: A

How It Works (Key Shaders)

No single shader does it all. The most common combination:

  1. Temporal Anti-Aliasing (TAA) or MXAO’s temporal component – Blends data from previous frames.
  2. Motion Blur shader (e.g., Marty McFly’s Motion Blur) – Extends blur trails.
  3. Frame averaging via custom shaders like SSR (Screen Space Reflections) with accumulation or LongExposure.fx (available on GitHub).

The principle: sample and blend several recent frames with decay, giving moving objects a directional smear while keeping static backgrounds sharp.

Essential Shaders for Long Exposure

Not all ReShade presets are created equal. You cannot achieve long exposure with just SMAA.fx and LUMASHARPEN.fx. You need specific accumulation shaders. Disable the game's native motion blur

If you are installing ReShade (version 5.0 or higher), make sure to check the box for the Legacy Standard Effects or download the qUINT shader pack (by Marty McFly). Here are the specific files you need:

Part 7: Which Games Work Best for ReShade Long Exposure?

Not every game plays nicely with temporal accumulation. Here are the top 5 titles where this technique shines.

  1. Cyberpunk 2077: The neon rain and vehicle density make for stunning light trails. (Requires disabling Ray Reconstruction as it conflicts with ReShade add-ons).
  2. Forza Horizon 5: The motion blur vectors are excellent. Use "Shutter Drag" method for drifting smoke.
  3. Horizon Forbidden West: The tall grass and waterfalls respond beautifully to the Accumulator method.
  4. Star Citizen: Capture the vastness of space stations with ship thrusters becoming constant beams.
  5. Assetto Corsa (with mods): The ultimate game for realistic photography. You can simulate 2-second shutter speeds on the Nürburgring.
