Using the Grid Technique to Achieve Perfect Dimensions
If tracing isn’t an option – or you really feel that it is cheating (I don’t think it is) then using a grid to copy your image may be just the thing. You can break down any image you want into shapes by placing an acetate grid over a photograph. You can also copy the photo and draw your grid right on to it. By studying the shapes in each individual square, the image becomes more abstract and a lot easier to draw. You can further your objectivity by turning the picture upside down which will make it even more unrecognizable.
With your pencil and ruler, draw a graph on your drawing paper. Use the same size squares as the grid you drew over the photo. This will make the drawing the same size as the photo. (I usually use a 1 inch grid.) If you want to make the drawing bigger then go to a larger square on your drawing paper. (1.5 inches)
If you draw the shapes inside the boxes as accurately as possible, all of the lines will connect properly and create the desired shape. Be sure to get everything, including shadows and highlights – these areas should be viewed as shapes also.
When you are finished and you are sure you have drawn as accurately as possible, then you are ready to transfer your drawing onto the paper you will use for the painting. (watercolor paper, canvas, acrylic board). You will transfer the image using graphite paper which is like carbon paper. Gently tape the image you just drew onto the clean paper. Put the graphite paper, dark side down, under the drawing, and using a pencil trace over the drawing you just did so that it shows up on the paper below, but without the grid lines. Once the image is transferred onto the clean paper you can paint or color it using the medium of your choice.
