Looking at our sets of kitchen measuring spoons, with their patina and scratches from long use in a hard-working family kitchen, I noticed the pattern of concentric ovals, particularly when each set of spoons was positioned so that light hit the upper edge of each spoon, and was withheld from the concave interiors.
To control the light, and the reflections in the spoon interiors, we lined a large bucket with black velvet, creating a raised stage within the bucket, also on black velvet. This way I was able to control the light coming in across the measuring spoon sets.
For both images I used a 100mm macro lens tripod mounted at f/22 and ISO 64. Each image is combined from eight exposures, with shutter speeds ranging from 1/4 of a second to 30 seconds.
