ONE advantage of the discovery of the Photographic Art will be, that it will enable us to introduce into our pictures a multitude of minute details which add to the truth and reality of the representation, but which no artist would take the trouble to copy faithfully from nature.

Contenting himself with a general effect, he would probably deem it beneath his genius to copy every accident of light and shade: nor could he do so indeed, without a disproportionate expenditure of time and trouble, which might be otherwise much better employed.

Nevertheless, it is well to have the means at our disposal of introducing this minuti® without any additional trouble, for they will sometimes be found to give an air of variety beyond expectation to the scene represented.
