Two years ago, another artist and I argued about something and each took the challenge to create 20 different paintings from the exact same still life setup without moving the items from their original position.
The object was to only use the original set up as the starting place. Through revisions and variations in Line, Shape, Sizes, Values, Colors and Textures we both discovered that the possibilities were endless.
These sketches were some that were used along the way. After finishing the 20 pieces (all hasty experiments, incidentally) I had so many ideas that I completed over 60 paintings using the identical set up. One can quickly see that sketching like this offers up enormous possible outcomes in value and shape alone
We both learned so much from the exercise that it completely changed our painting thought processes forever.
