This was an experiment. I was looking at a painting yesterday that I really liked. The artist explained that she had cut out pictures of dishes from various magazines, assembled them in an arrangement she liked and painted it.
I thought, that sounds easy! I'd just gotten a food magazine with a picture of two pears that I liked. I found a picture of an urn in another magazine and decided that would make a nice arrangement. I made a sketch and started painting.
I was having a great time and was about 2/3 finished when I realized the lighting on the urn came from one direction and the lighting on the pears came from another! I decided it would be easier to leave the urn as is, so I changed the lighting on the pears. I think I really prefer painting from a set up rather than from a photo, at least until I gain more experience.
