Most drawing manuals and websites out there talk about the square-by-square method of gridding an image. I decided to use a different method during this lesson with year 7 students. I found it takes a little while to get the hang of it - dealing with triangles and rectangles at the same time instead of just simple squares can get confusing - but it can be useful on detail. I subsequently found this is the method used by many master artists, at least in France.
1. You start with your original image.
2. You draw two diagonals from corner to corner of your image. If your image is not a perfect square or rectangle, or even if it is a shape like a circle, draw a square or rectangle around it to make your diagonals.
3. Now you draw vertical and horizontal lines dividing the image in quarters, so that everything intersects in the middle.
4. Do the same thing to create your second grid that you will transfer into.
5. You may already have segmented enough to be able to get to work copying the drawing.
6. If see that part of the drawing you are copying has more detail than in other parts. you can develop the segmenting so you can really get those details accurate.
7. So I do the same routine in that smaller rectangle in just that part of the drawing - diagonals, vertical, horizontal - to create 8 new smaller triangles within that rectangle, along with 4 new smaller rectangles. It will be easier to get the detail accurate in the copy, because you will be dealing with smaller pieces of the drawing. If you want even more detail, you just choose one of the smaller rectangles and do it yet again.
I thought this worked really well to transfer the image to create our finished portraits and will developing this to scale up a drawing of one of the great masters next lesson.
Pupils should be taught to develop their creativity and ideas, and increase proficiency in their execution. They should develop a critical understanding of artists, architects and designers, expressing reasoned judgments that can inform their own work.
