Bob, this may sound dumb, but could you demonstrate the grid method? I keep reading about it, but I don't know how to do it.

Thanks, Elizabeth
Different artists do grids differently. But many artists use grids to transfer an image from one source to a canvas or drawing surface. I use them mostly to enlarge a small photo and sketch it on a larger canvas when I do oil portraits. It helped me keep the same proportions. Now I prefer measuring points on the photo instead of drawing the grid. It helps me to study the lines and shapes better than the grid method.
Basically you draw evenly spaced vertical and horizonal lines on a picture. then you draw this same spaced lines on another drawing surface. Then you draw the outline of the picture by using the lines of the grid to locate the lines in the source picture.
When I used the grid method for enlarging I measured my source photo. I used tracing paper, because I couldn't draw on the photo. If I did this now I would scan the photo and print a copy of the photo and draw the lines on the printed copy.
Then I divided the photo in three or four rectangles the same ratio as the lines I would use on the canvas. For example I usually used 1:1.25. An 8 x 10 photo and 16 x 20 inch canvas have this ratio. On my canvas I drew four lines four inches wide vertical. Then I drew five lines four inches wide horizonal.
On the 8 x 10 inch tracing paper my lines were four lines two inches apart vertical and five lines 2 inches apart horizonal. When I had my grid on the tracing paper I traced the outline of the face in the photo on the traceing paper. Then I drew a grid on the canvas lightly. The lines of the grid helped me locate the lines on my canvas. This still takes a good eye and skill. I would in no fashion call it unethical or wrong. But this is just my opinion. If someone thinks it's wrong then they shouldn't do it. lol.
I don't have a step by step picture example on file but if you need a step by step illustration I can do one.
