Lucy was our instructor for the Wednesday class and took us through the use of grids when drawing accurately. Anytime you want to draw something that requires accuracy such as a portrait, pet, vehicle, a complex still life, etc. we may wish to use the grid method.
It starts with drawing a grid of squares over the photo of the work you wish to copy. These squares can be numbered and lettered to make it easier to follow when drawing. Next you then draw the same numbers and letters of squares onto your drawing paper/canvas. You then
carefully copy each square from the grided photo copy onto your painting/drawing surface. Be careful at the corner of the eye and bridge of the nose as these can be tricky.
If you don’t wish to mark the photo you can always copy the grid onto clear acetate and layer it onto the photo. There are also various grid drawing assistance apps on your tablet which you can download and layover the photo to be copied.
