Traditional long exposure photography captures light over a prolonged period (seconds to minutes), producing effects such as light trails, silky water, and motion blur. In real-time rendering (video games), this effect cannot be achieved by simply slowing the shutter due to the discrete, variable frame rate. This paper examines the use of , an open-source post-processing injector, to computationally approximate long exposure via frame accumulation techniques. We analyze the implementation, performance costs, visual artifacts, and practical applications in interactive media.
It is most commonly used in racing games or flight simulators to create "speed lines" or motion blur that looks more natural and cinematic than the game's built-in settings. Virtual Photography:
When prompted to select effect packages, ensure you check the following repositories: reshade long exposure

Best used when driving at night in games like Cyberpunk 2077, Forza Horizon, GTA V.
ReShade cannot physically hold open a digital shutter because video games do not render light that way. Instead, ReShade achieves a virtual long exposure through .
Long exposure photography involves using a slow shutter speed to capture a scene over an extended period. This technique allows you to create stunning effects, such as light trails, blurred water, and star trails. Long exposure photography requires a combination of technical skill and creative vision, as you need to balance the exposure settings with the desired effect. Whether you are focusing on or fast-moving action/vehicles
To get started, you need the right tools. Standard ReShade installations come with basic effects, but long exposure requires specific shaders designed for frame accumulation. Ensure you download these shader packages during your ReShade installation or add them manually later. 1. MovingInCircles (by BlueSkyDefender / AstrayFX)
Choose the rendering API used by the game (DirectX 11, DirectX 12, or Vulkan).
Open your ReShade overlay (usually the Home or End key) and activate your chosen long exposure shader. Adjust the following parameters:
. These shaders hold previous frames in memory and blend them with the current one. Motion Blur Integration: Shaders like MartyMcFly's Motion Blur Optical Flow In real-time rendering (video games), this effect cannot
However, if you are a virtual photographer, video creator, or PC gamer, you can replicate this stunning effect in real-time using ReShade.
As new frames are rendered, they are layered onto the old ones, creating a "trail" or "smear." Light Trails:
This effect is a game-changer for virtual photographers. It adds a layer of realism and artistic flair that standard post-processing can't achieve. Give it a try and share your results below!
