1- MAKE A HI‑RES BLACK & WHITE (16‑BIT) VERSION — SOLDIER ON HORSEBACK

1. Open the soldier image in Photoshop or GIMP

2. Convert to grayscale

This removes sepia tone and prepares it for heightmap work.

Photoshop:  

Image → Mode → Grayscale

3. Clean the image (THIS is what makes it “hi‑res B/W”)

A. Levels — remove paper texture

You want the soldier + horse lines dark, background clean white.

Photoshop:  

Image → Adjustments → Levels

Move sliders:

• Black point → right until lines are solid black

• White point → left until background becomes clean white

• Midtones → adjust until the distortion lines look crisp

B. Noise cleanup

This prevents Depth Anything from creating “micro bumps.”

Photoshop:  

Filter → Blur → Gaussian Blur → 0.5–1.0 px

C. Optional: Dust & Scratches

If the paper grain is heavy:

Filter → Noise → Dust & Scratches → Radius 2–4

4. Convert to 16‑bit

Depth Anything requires 16‑bit for smooth heightmaps.

Photoshop:  

Image → Mode → 16 Bits/Channel

GIMP:  

Image → Precision → 16-bit integer (gamma)

5. Export the hi‑res black & white file

This is the file you will feed into Depth Anything.

Photoshop:  

File → Save As → TIFF

Settings:

• Compression: None or LZW

• NO JPEG compression

• Keep 16‑bit

This TIFF is now your hi‑res black & white 16‑bit soldier image.

4. Comfyui - Workflow- Depth Anything

5- TextureApp.app to convert Depth Map to Height Map
