0 to give too little light to a piece of photographic film when taking a photograph --
If underexposed it will show no details in its lighter parts and the shadows will be black; and a black shadow is nothing less than a blemish.
I photographed it, and the rocks "took" well, but as regards the gnomes, the film was underexposed.
As a rule, it is advisable to somewhat underexpose in order that the development be regular, progressive, under control.
