How to put photos onto a canvas
Pick a photo and draw on a piece of computer paper or rough draft paper, the photo with pencil.
It's ok if it's not perfect because remember-this is your artwork!
Take a canvas about the same size, maybe a little bit bigger, than your drawing and put graphite paper over it.
It will need to be dark side down.

pick from the following.
(a). If you find yourself in a dark room, make sure any or all lights are completely off. Lights are not good because the photo is too dark.;
(b). Cover as much of the canvas area as possible and leave it like that. Now colour the image with the pencil or cut it out in around half by drawing the outline.;
(c). If both sides look the same, take your index finger and thumb and rub both sides. Graphite will get on one of your fingers and that's the side you will put face down.;
(d). Wait until it is dark enough to color. Flip the paper on the long side so that the background colour looks and blends.;
The answer is:
(c).
