I was wondering what good technique for transferring drawings to canvas/panel would be, specifically when the drawing is smaller than the intended size for the painting? I watched Joshua LaRock's portrait video, and it looks like he used a projector. I'm wondering, did he scan the drawing and then project it, or take a photo of it and use the file to project it? Does the projector and or/camera distort the image at all before transferring? I know the grid method works, but a projector seems to capture the finer points of the drawing far better. Any thoughts?
