Finally got past the “rendering” issue i was having. So I tried these two photos to see how they would turn out. I think i want to play with the images some more in a photo editing package , but i am liking the possibilities. these are printed on some cheap canvas boards i got last year on amazon, nothing done to them.
Very cool! One thing you might try is spray painting the canvas black and inverting the image. I found that I get a lot better gradations with that combo.
Of course the subject matter is the star, but the canvases look really good! I think just a little bit of tweaking can fix the white hair issue, but just the way it is look fine too.
FWIW, this is a decent example of editing that might give you a few ideas.
