When you want to draw an image onto a canvas, it may be helpful to use a projector. You can also use the projections as inspiration for freer action when painting.
Projectors are best for structural work and not good to judge colors from.
To get the best results when working with projectors, it is important: 1 The projector is securely fastened to a wall. 2 The projector is in HD resolution. 3 The projector has been turned on 20 minutes before use. The hardware must settle. 4 The canvas must be set up on a solid wall.
