This is class reference for Impington drawing and mixed media, 
Sawston and Cambourne drawing and watercolour.
We looked at images which were tonally light and tonally dark in colour and black and white,

Then we did a tonal grade of 10 boxes ranging from light to dark in pencil, and used this as a guide to gauge the tonal range of the cone ball and cube exercise below.
We scaled up the the image to make our drawing larger, but proportionally accurate using a scaling grid.
Because of the use of diagonal lines, the grid can be enlarged or decreased in size.
The grid is used as scaffolding to locate the position and proportions of the objects, however, some people can draw this accurately by eye and may not need to use a grid like this.
We made the scaling grid by placing the photo near the bottom left of our drawing paper, we then drew lines extending from the bottom and left edges of the photo, then, before lifting it up we drew a diagonal line from bottom left and top right corner and beyond onto our drawing paper.
Having done this, we removed our photo from the paper, and joined up the bottom and left lines to meet each other on the bottom left corner, and using a set square, joined up the right and top lines to meet with the diagonal on any point on that line depending on how big we wanted our picture to be.
See grid above, the shorthand of this is to draw the union jack based on the proportions of your photo.
See above.

Below are some examples of learners accurately drawing proportions and tonal ranges.


 The 2 still life's I brought in were to demonstrate groupings of objects with tonal ranges at extreme ends of the tonal scale.
Look at the absolute whites, especially on the white vase, and ask yourself what tone the vase is if it isn't as white as the highlights.

Next week, drawing and watercolours are going to complete their tonal drawings using watercolour.
And Impington are going to use charcoal, which I will supply
