Who thought they undestood RF grayscale engraving?
Two years ago that was me and, despite my confidence and best efforts, the results were always a fuzzy weak contrast , maybe 3 out of 10.
Now, with so much more knowledge of how laser beams and lenses interact, I felt I could explain why the "weak contrast".....but could I fix it? I also was confident about correcting the "fuzzy". content.
As with all my videos, this turned out to be a journey peppered with amazing discoveries. I am sure will find the results unexpected.
