Blood oranges, which are available in my area only from about December through March, are great for making red sauces at Christmas time. They're also fun to photograph!
This is only the fourth scene I've photographed using my newly acquired macro lens, so I am surprised and happy to realize it can be used so effectively in a composition that includes out of focus objects in the background. Considering that it's a 90mm lens only 9 inches (23 cm) from the subject, I expected the oranges another 9 inches to the rear to be just an unrecognizable blur of color. Fortunately, I was wrong. Knowing how the optics work in scenes such as this one makes all sorts of compositions possible using the macro lens.
The magnification ratio is about 1:2.5, which means the entire scene is only about 2 1/2 times larger than the sensor. The photo would make me think the scene is a lot larger. Another way of putting it is that the sensor is 40% the size of the scene.
Setup
The background is translucent vellum lit from behind by a small continuous-light lamp fitted with a yellow gel. The oranges on the left side are on a small block of wood painted flat black. Those oranges are lit by a small continuous-light lamp placed at their right side. A speedlight lights the foreground slice from the rear to take advantage of the subject's translucent areas. It also lights a white reflector on the left front side of the scene that reflected light back onto the slice to brighten the front of it.
