This proved to be more difficult than I first thought because the subjects I tried first turned out not to be suitable for showing the distinction between the location of the studio lights. My first attempts were with a bunch of grapes but because all the surfaces are curved, the shadows appeared soft regardless of the position of the lights. (See photographs below).
I then photographed an aloe plant and because of the shapes of the leaves, was able to demonstrate the difference in shadows depending on the proximity of the lights. Here are 6 photographs with a information on the lighting for each one.
I had the camera set on auto white balance, and in the camera the background appeared the same colour. However, when I downloaded and printed them, the photographs taken with a flash were pale pink. I could have changed the white balance post production, but decided to leave them as they were to show that auto white balance does not always produce consistent colours.
