Kids’ needed to go to HD for some stuff yesterday and I managed to piggy-back a carton of ceramic tiles onto their shopping list. These are my first full-tile engravings… 2.5W laser on DIY CNC machine, 1200 mm/min, 85% power, Jarvis dither, ~300 DPI, unrecognizable faces…
Pretty pleased with the attempt. Obviously need to learn how to measure tiles properly and center the image… and need more practice processing photos for lasering (I know virtually nothing about photography…). The rest of it is a piece of cake. Thanks, @Bulldog, for the inspiration.
@dkj4linux Amazing for first time woo…for centering I place a small piece of masking tape in centre,draw a line from each cross corner…focus laser on small x…remove tape set job to cehtre
To my untrained eye, the Milkmaid photo engraved best… and her preview is darkest overall. Then Charles Bronson, then Patrick Stewart (too light, too little contrast?).
Here I have the Milkmaid selected… and shape properties shown. I usually set the gamma first, then enhance radius, enhance amount, and, finally, brightness and contrast… until it looks about right to my untrained eye. May totally be the wrong way to go about it but it’s what I do… until I know better.
I have an incredibly talented teenage grand-daughter who loves to sketch… and fills sketchbook after sketchbook with very detailed scenes, lots of activity, and recurring characters; i.e. there’s an almost “Where’s Waldo” quality to it. She imagines something in her head and it seems to magically flow out her fingertips. It’s really fascinating to watch and I’m very proud of her. This was a quick snapshot of just one page among many…
Reading through all this to start getting into this myself…
