A few years ago, I had a summer project to cover a really large canvas. How big was this surface? It's stretched the perimeter of an office space. Because it was white, I chose to do a classic cinema theme and painted with black acrylic. I am not an expert painter, but I knew graphics. To execute each image, I experimented in dry and wet applications to achieve the right shades of grey. And as with all oversized conversions, I had a problem with perspective. The Maria robot from Metropolis was entirely out of proportion. It didn't help that I had to use a stepping stool to reach her head and then crouch down to finish her feet.
You know. Given I would like a chance to paint in this scale again.
