Alright this one might take some explaining.

To create these spray paint portraits of Brockhampton, I would find a picture of them, posterize it in Photoshop, and then section off each unique area of the face (shadow, highlight, etc) as a different layer, resulting in 4 different layers, or stencils, per portrait. I would then print each layer out on their own pieces of paper, and put transparent plastic over the paper, and cut out the stencil using and exacto knife. I would then spray each stencil/layer on the canvas, wait for it to dry, then go onto the next one, etc. I am super happy with the results!

Here are the digital files and versions of each stencil I made, before printing them out.
