What reading level is Photographic Amusements Including a Description of a Number of Novel Effects Ob book?
To quickly assess the difficulty of the text, read a short excerpt:
To obtain a sharp image a very small diaphragm must necessarily be used, but with a rapid plate and good light that is of little moment. The camera should be placed in the dark room, the lens being inserted in a hole in the partition just its size, and the subject in the adjoining apartment opposite the lens — -this because the cone will not allow the plate-holder to be closed by the slide.
Fig. 76 shows the arrangement of the camera and holder. The exposure made, the film is developed, as usua...l. The negative gives a print deformed as shown in Fig. 76. The original, if not grotesque appearance of the head disappears when the print is rolled into a conical form and the observer places his eye in the prolongation of the axis of the cone. Fig. 78 shows the head as seen under these conditions.
MAKING DIRECT POSITIVES IN THE CAMERA.
Prepare a saturated solution in water of the crystals of thiosinamine, and add from two to eight minims of it to an ordinary pyro or eikonogen developer. Expose rather less than usual.
