He balanced those fields in such a way that particles of different charge-to-mass ratio curved differently and fell in different sports on a photographic plate
X-rays can be of various strengths to penetrate different organs so that a picture is shown on a photographic plate
There is a screen of varying transparency mounted in the main camera lens system that is moved in accord with the amount of light that the electric eye sees, letting more light fail on the photographic plate
An instrument outfitted with such a mirror and corrector plate is called a Schmidt telescope, or, since it is invariably used with a photographic plate

X-RAY X-rays can be of various strengths to penetrate different organs so that a picture is shown on a photographic plate
We repeated this process for each of the superior images selected from each photographic plate
Each photographic plate
measures about 14 inches square and records a patch of sky about 13 times as wide as the moon.
He took many sequential exposures of a planet on a single photographic plate
in rapid succession, and then he combined the images into a composite print using a specially constructed apparatus that precisely adjusted the paper's position to register each negative.
A glass prism placed over the objective lens of a refracting telescope allowed the spectra of an entire field of stars to be recorded on a single photographic plate
