I spent most of Sunday and a few hours today playing around some more with canvas. Here are my results. The first canvas started out like this:
And using an old B&W photo from my younger days, I got this:
I played around with a few things and did the Orion Nebula from a nasa shot. The inverted photo looked like this:
The lasered canvas turned out like this:
I went back and dotted in the stars with a silver sharpie.
Note: My best results came with a double clear coat over the original slashes of color, and let it dry overnight before the black top coat (thank you @evansd2 for the suggestion). The colors come out much better this way as you can see from the two signs I made below:
These are for my upstairs Office and Glowforge rooms. The colors on these pop a bit more, but sometimes the muted is nice too.
You also don’t have to go with just black. This one was done with a top coat of grey primer and a light misting of gold metallic. I had intended the green to go behind her eyes but I was a little low. Spray paint is a bit of a guesstimate, but I am okay with that. The non-perfection is way more interesting to me.
And now I need to order more canvas.
