Attention is called to the Haar and Walsh functions as being potentially useful in engineering applications. The Walsh functions have a single magnitude with either a positive or negative sign in the range of definition. Each member of the Haar family also has a single magnitude although this magnit

In the proper field of the art of photography and its practical applications, it is not the number and size of the individual grains made developable by an exposure which are required, but the macroscopic, summary effect of the presence of such grains, the opacity of the film or plate over which the
