# Photo mockups — credits & method

The realistic garment mockups in this folder are built from **blank-apparel base
photos from [Unsplash](https://unsplash.com)**, each then **recolored and composited** with the
NLT merch designs from [`../designs/`](../designs/) (via [`build_mockups.py`](./build_mockups.py)).

## How the mockups are made

`build_mockups.py` (numpy + scipy + Pillow):

1. **Mask** the garment — brightness threshold for the tee (bright garment on dark wall),
   largest-bright-component for the sweatshirt, bright-crown threshold for the straight-on cap.
2. **Recolor** tees and sweatshirts to the target colorway by scaling the original luminance
   (so folds, shadows and sheen are preserved). Caps stay white (logo-only) — the cap base
   has uneven left-panel shadow that breaks full-garment recolor.
3. **Print** the design into industry-standard zones:
   - **Cap front:** centered on front panel (~4.5″ × 2.25″ equiv.)
   - **Left chest:** wearer's left, ~3.5″ wide (professional / tonal marks)
   - **Center chest:** large front graphic (8–12″ equiv.)
   - **Sleeve:** outer left sleeve on hung tee
   - **Back center / yoke / back neck:** large back graphic or yoke trail on back-view bases
4. **Crop** to the garment with padding and export at up to 1280 px.

Regenerate after changing a design, placement, or colorway:
