For this Research I was to try lounging on a couch with a mirror facing me from the foot end, then draw my body as I saw it in the mirror. My feet should be huge in comparison with the rest of my body. This effect is called foreshortening I then had to find any images were an artist has used foreshortening to create a particular effect.
Jenny Saville is a good one for this as she uses foreshortening in her figure drawing which accentuates the flesh. This can be seen well in this painting called Plan.
Also there is the Grid reference illustration published by Albrecht Durer where he depicts someone looking through a string grid and transferring what they see to a drawing surface which had a grid on.
