Exploring Slow Shutter Techniques in 3D Gaussian Splatting

3D Gaussian Splatting not only handles glossy and reflective surfaces that are difficult for traditional photogrammetry — it also allows you to bring slight motion blur directly into the 3D representation.
This opens the door to more artistic and expressive visuals that were previously hard to achieve.

[Creative Expression] Slow Shutter & Light Painting

With 3D Gaussian Splatting, it’s now possible to capture intentionally soft or ambiguous visuals that traditional photogrammetry simply couldn’t handle.

By using slow shutter speeds (3–6 seconds) and moving LED lights, you can record light trails — and even blur itself — as part of the 3D scene.

Below are some examples of [Slow Shutter] Gaussian Splatting in action!

Light Painting Example 1

Single-color LED light painting with a 3-second exposure

Light Painting Example2

Light Painting with Different LED Colors Front and Back – 6-Second Exposure

Light Painting Example3

3-Second Light Painting with a Color-Changing LED

Light Painting Example4

3-Second Slow Shutter with Light Trails + Single Strobe Flash
— Slash Effect Style

Light Painting Example5

6-Second Slow Shutter with Light Trails + Single Strobe Flash — Stylized Slash Effect with Ink-Like Look Using SuperSplat v2.5's Color Correction

Light Painting Example6

6-Second Slow Shutter with Light Trails + 5 Strobe Flashes

Slow Shutter Example 1

6-Second Exposure with Partial Motion Blur

Slow Shutter Example 2

6-Second Slow Shutter with Partial Motion Blur

Slow Shutter Example 3

6-Second Slow Shutter with Partial Motion Blur
— Evoking Hokuto Shinken-Style Movement

Slow Shutter Example 4

6-Second Slow Shutter with 6 Flash Bursts

Since it’s a 3–6 second long exposure, some motion blur is unavoidable.
Rather than aiming for razor-sharp detail, this approach leans more toward a graphic or expressive visual style!
