Not a photo.
Change only the direction of the light, and how each point brightens tells you which way that part of the surface faces. That is enough to reconstruct the shape.

3d shape reconstruciton with #photometricstereo
One capture, and colour and shape come apart.
2D Texture keeps the colour and pattern. 3D Surface keeps the relief. Surface Normal encodes which way each point faces. Same shot, all of them, via FORESIGHT STEREO®.

Here is my photometric stereo workflow. The blend and image dataset can be found in my Patreon. #b3d #3dscanning #photometricstereo

Photometric stereo practice with banana chips. I accidentally moved the cloth background with the flash so the albedo and normal ended up blurry in the processed result. However, it's lesson learned so I'll be more careful next time. #3dscanning #photometricstereo
Now we can achieve excellent results on a single photo (We created LLM with 92,000 scan results and nearly 1,000,000 RAW scan Photos). I used a Beech tree branch that I took a photo of before @ScansLibrary even existed.

Roughness prediction in shadowed areas is much better now.
Not shadowed areas are also opimized closer to reality so that's a total win.

Visual Inspection of the CAR with Photometric Stereo

It's also fully modular, now it's 1,7m high and 1,7m long but can be easily adjusted to fit any purpose.
Everything is still under heavy development of course.

I don't know how to use substance designer or any other material authoring tool so I've built my own little normal map generator in blackmagic fusion. It's a super cheap setup and I doubt that my math is correct but it looks kinda normal 🌿

We create a light pattern inside that allows the camera to detect tiny deformations from a single image.
A masked LED ring with different colors creates a good illumination: few colors overlap, bright enough, no oversaturation.

I plan to create a tutorial about preparing super detailed scans of 2m long planks with #photometricstereo technique + texturing and maybe some hardware tips, are you interested?
