Utilizing light and contrast in your artwork
Light and contrast are two things that go hand in hand. If there was no light, there wouldn’t be any contrast either, because everything would be shaded. In our world, there’s always light, unless you go deep underground or are in some airtight kind of structure with no lights on.
Light is what helps us not only to see but also to understand textures. Without this light, we can of course feel our way through and figure out materials on the go, but being a very visually oriented species, light helps us out way more.
