Swiss artist Simon Berger has been working with portraits made out of glass for three years. It's a process that requires delicately hammering his canvas to create just the right cracks.
Sometimes it takes him one try, but other times it can take him five.
Glass is pretty much monochromatic, so the secret to making the portraits pop is creating dimension through light and dark sections.
Simon Berger developed his techniques through trial and error. To get the depth he wants, he now has a clear idea of how many times he has to hit the glass.
To minimize the chances of shattering his canvas, Simon works with laminated safety glass.
