When it becomes too cold for the amateur photographer to take pictures outdoors, he generally lays aside his camera and thinks no more about it until the coming of another spring or summer. While some winter scenes would make up an interesting part of anyone's collection, it is not always pleasant to go out to take them.
Some derive pleasure from making groups and portraits, but this is very difficult, if the room is not well lighted. Overhead light is the best for this work and few residences are constructed to furnish this kind of light.
I find a very good way to get a light overhead is to take a large mirror - one from an ordinary dresser will do - and place it in the window in such a position that the reflection will strike the ceiling just above the subject. The result will be a soft but very strong light, almost equal to a north skylight. Splendid portraits can be made in this way. - Contributed by Chas. Piper, Kokomo, Ind.
