A friend of mine who is a high school teacher shared with me how they struggled to take a clear photo of a fish's gill.

The photographed pictures weren't clear enough. They wanted to use the photos in a biology text book which was to be printed. They took so many photos without success, and wondered how other published book's photo of fish- gills were taken.

Then they tried putting the exposed gill of the fish in clear water. They got a clear excellent shot.

Just thinking that all animals which live in water are better photographed in water. Maybe the birds are better photographed on air. Maybe we are most innovative at our homes.
