The cathedral at Florence is so shut in by adjacent buildings that it must receive other treatment. The vast amount of work upon the façade is lost to the casual observer because of the propinquity of the baptistery, which completely destroys the effect of this wonderful mosaic. Standing on the sidewalk, as far from the façade as the other buildings would permit, I made the general view of it with a lens of four inches focus, then retreating still farther, till a corner of the baptistery began to interfere, I used the telephoto attachment on the central rose-window, the camera being about a hundred yards from it [pp. 460-61]. Then taking a position beside the baptistery I telephotographed the mosaic over the central door. It will be noticed that in the telephotographs there is less distortion than in the ordinary view, for although the rose-window is over a hundred feet above the pavement it was photographed from such a distance that only a slight inclination of the camera was necessary, and the picture appears as if taken from an elevation, whereas it was actually made from the sidewalk. The delicate carving and mosaic work about the central door are distinctly brought out, and it is one of the best examples of telephoto work the attachment has made.

St. Mark's Cathedral offers many studies for the camera, and for many years the glass mosaics upon the upper part of the front of the building were a perplexing problem to me, for the balcony was too near and the pavement below was too far away for successful work with the ordinary lens; and if taken from a near position below they were so distorted as to be useless. The problem was not solved till the advent of the telephoto attachment, which procured the studies with ease. After making a picture of the whole front of the cathedral from the centre of the piazza in the ordinary way, the camera was moved a little to the right, so that one of the large flag-poles would not interfere, and the upper left-hand mosaic, representing the "Descent from the Cross," was telephotographed [pp. 466-67]. The result is about the same as that which might have been obtained in the ordinary way from the top of a scaffold fifty feet high and about forty feet from the mosaic.
