Getting better results
- Get close: fill the frame with the wood.
- Raw, planed or sanded wood shows the grain best. A slightly damp surface helps too.
- Furniture: photograph an unfinished spot, like underneath or inside a drawer.
- Floors: get close to one clean board.
- Use bright, even light and avoid flash glare.
- If the result says “Possible match”, follow the tip in the note and scan again.
