Jupiter

Sketching: For this sketch I used: black Strathmore 400 Artagain paper, 8”x 11”, and a white Conte’pastel pencil. I added the moons to the black paper using the white pastel pencil. The sketch of Jupiter was done on white sketching paper using HB, 2B and 4B graphite pencils an eraser shield, and a blending stump. I carefully cut the sketch of Jupiter from the white paper and using a small piece of double sided carpet tape added it to the black paper. Brightness was slightly decreased (-4) and contrast increased (+3) after scanning using Microsoft Office Picture Manager.
