When selecting wood for laser engraving photos, some types stand out due to their density, grain, and overall finish. Here are a few of the best options:

• Birch: This hardwood has a fine, even grain which allows for high-resolution engraving. Its light color enhances contrast, making it ideal for detailed photo engravings.
• Maple: Known for its smooth surface and light color, maple provides excellent results in laser engraving. The subtle grain ensures that images appear sharp and clear.
• Pine: While softer than other options, pine can still deliver great results, especially for rustic or natural aesthetics. Its lighter color helps in producing a good contrast in images.
• Cherry: Cherry wood darkens over time, which can create a beautiful backdrop for engraved images. Its fine grain and warm tones can enhance the overall look of photos.
• Mahogany: This hardwood is prized for its rich color and durability. Mahogany offers a striking contrast for darker engravings, making photos appear vivid.

Ultimately, the choice of wood may depend on the desired effect and the image quality needed for the specific project.
