For engraving, you need to make sure the picture is set up to translate successfully into a laser etching. This won’t be a problem for simple logos and symbols, but if you want to make etchings with photos you’ll need to do some image editing in an app such as GIMP, Paint.net, or Adobe Photoshop. Glowforge’s website offers a few guides to preparing photos, but basically you want to convert your image to black and white, sharpen it, and adjust levels to bring the histogram toward the middle.

Still working on getting the settings right, so it cuts the wood, but doesn’t set it on fire.
