What reading level is Photographic Optics: Including the Description of Lenses And Enlarging ... book?
To quickly assess the difficulty of the text, read a short excerpt:
If^ after having put on the diaphragm, it becomes necessary to draw back the focal plane (the ground-glass of the camera), to preserve the primitive sharpness of the image, the objective possesses positive aberration; if it is. necessary to advance it, negative aberration.
The examination, however, may be made still better by reproducing the wafers by photography, first with the whole aperture of 1^ objective, then with a small diaphragm on the objective, and without changing the focus. The two... images should be equally sharp.
♦ Two waffere answer equally weU.
ABERRATIONS. 75 Spherical Aberration serves to divide Photographic Objectives into two very distinct classes. — There are dif- erent forms of photographic objectives. Some can be employed with their entire aperture, and then give a* sharp image, bnt of little extent ; the others (employed with their whole aperture) give only confdsed images. This is because the former are aplanatic — ^that is, because their aberration is corrected by the arrangement of the lenses which form them, and the second are not so.
