Pictures of white people turn out fine, I'm looking for some advice regarding engraving pictures of black people. Dealing with a 9Tu-M044 Fiber Laser machine, and I'm trying to offer picture engraving services.

I've tested Obama, Snoop Dogg and Tupac, but I can't get the right brightness and contrast. On the contrary, engravings of Bernie Sanders showed clearly at a variety of settings. Landscape pictures also showed clearly.

The way this machine works is that if the picture is black, it engraves. Gray engraves lighter. Ignores white. White people need to be grayish in the image. Uses EzCAD2 as the engraver source. I use GIMP, Adobe Illustrator, and Inkscape, depending on the project.
