Choosing the Right Material for Laser Engraving Photos
Avant de plonger dans le processus de gravure, it’s crucial to choose the right material. Some materials work better for photo engraving because of their ability to provide clear contrast and fine details. Here are the best materials for laser engraving photos:

Preparing Your Photo for Laser Engraving

Laser engraving works best with grayscale images. Use photo editing software like Adobe Photoshop or GIMP to convert your photo to grayscale. This allows the laser to interpret the light and dark areas correctly and create better contrast during the engraving process.
Tip: Adjust the contrast to ensure that the dark areas of the photo are sufficiently dark, and the light areas are bright enough.
3. Resize and Crop the Image
