Right here it might be well to say that the longer the neg-ative is allowed to remain in the whitening solution, the greater will bethe resulting density. This part of the process should, therefore, befully watched, although, should the intensification be too marked,the density can be reduced with the usual fixing bath of hypo.

)T0 BY JAMES SHEPARD. ROARING BROOK, SOUTHINGTON, CONN. 45 The intensifieT as given above is not a novelty. Edward L. Wilsonrefers to it in his Cyclopaedic Photography, but omits the details,which may be helpful to photographers. The purpose of this article isto call renewed attention to an intensifier that has been undeservedlyneglected. When I asked a professional photographer the other day which in-tensifier he was in the habit of using, his reply was : Never use any.When a plate needs intensification I throw it away and make anotherexposure. That is all very well, for he confines his business to por-traiture ; but circumstances may arise, even with him, that may ren-der the employment of an intensifier not only desirable, but imperative.
