The next few images I shall be posting are a series of challenges. There are ten of them called the Scavenger group, and they cover a variety of photographic subjects. I shall include both the index image, and my artistic development of it.
The first was titled Silhouette, and was taken at a festival in the dark as the person in front of me took a flash photograph. It was combined with a reflected fish in a fish-tank. The image contains the X-ray image of a person with a pneumonia that obscures the silhouette of the heart. This is known, unsurprisingly as the silhouette sign and is a very useful diagnostic tool.
