Tips on Laser Engraving on Wood

We can laser engrave halftones from photos or logos, but note that the effects on wood can be very subtle. The laser engraver interprets black as 100% power. White is 0% power. So naturally anything in between will be laser engraved with a power in between. In samples below you can see the difference in results using the same power or grayscale.
