When it comes to laser engraving photos, the choice of wood plays a significant role in achieving high-quality results. The best types of wood for this purpose are those with fine, even grain and a light color that contrasts well with the engraving detail.

Birch plywood is a popular choice due to its smooth surface and consistent grain, allowing for intricate details to be captured during engraving. Maple is another excellent option, providing a light color and a fine texture that enhances photographic details.

Cherry is often favored for its warm tones, which can add depth and richness to the engraved image. Its medium hardness allows for a precise engraving without excessive chipping.

Poplar is also suitable, being relatively inexpensive and easy to work with, although it has a coarser grain than birch and maple. Finally, Basswood offers a soft texture ideal for fine details, making it popular among hobbyists for engraving.

Ultimately, the best choice will depend on the specific desired aesthetic and the detailing required in the photograph.
