4 Setting up the canvas
For this workshop I’ve decided to do a portrait, so I’m going to use A3 size and 300ppi resolution. If you prefer to work on a smaller-sized canvas, you can always go A4 or A5, and lower the resolution to 72ppi. The smaller file size will suit posting online. In the File menu you can also select the colour of the canvas and the paper texture. I’ll start in greyscale, which I’ll turn into colour later using a glazing-like technique, so I choose a simple white canvas, without any gradients or shade of colours. I find it’s easier to build light and shadows using greys.
