On paper, I’ve used kneaded erasers to add effect to drawings. But erasing in an iPad drawing is another whole thing.
In Procreate, my current go-to drawing and painting app, all the settings that apply to pencils, pens and brushes also apply to erasing. If you can draw or paint with it, you can erase with it.
Erasing is not just for corrections. Taking away can be an intended part of the drawing process. Meaning subtracting can be adding — even in the positive space.
It was erasing that made the band-like lines in the detail below from my current WIP. I sketched and shaded with black over the color then dragged an “HB eraser” through that layer of the drawing.
Here you can see how the eraser takes on the qualities of the pencil.
In this screen grab, the eraser is being set for HB Pencil.
In this app, erasing is drawing.
