The Kodak Professional HR 500 Film Scanner is designed to quickly generate
high-resolution digital images from photographic negatives and positives.
The scanner accepts films ranging from 35 mm to 70 mm widths, including 46 mm
width film and the 120 series formats, with up to 90 mm frame lengths.
The scanner digitally captures images and stores them in files up to 128 MB
(format dependent) in size. The scanner is capable of variable magnifications
from 0.5 to 2.0.
How the Scanner Works
The image on the film is focused onto a Charged Coupled Device (CCD) that has
three parallel linear rows of light-sensitive elements, one row for each color. Each
of these lines is exposed to a corresponding line of image on the film. The time to
expose each line properly is controlled electronically and is a function of the:
•
sensitivity of the CCD
•
amount and spectral distribution of light from the light source
•
lens aperture
•
magnification factor
