Are awesome. I’ve been reading on watercolour painting for the past few months, and been working with Corel Painter for a bit before I headed off to the army. As opposed to working with stuff like oils and acrylics, you work from light to dark instead of dark to light, conventionally speaking.
It almost mirrors film and digital photography, where in the former you expose for the blacks and develop for the highlights and the latter vice versa. Really, it’s not that obfuscating once you understand the actual workings behind the smokescreen. Sort of.
