NOTE:
EACH DIVISION OF THE METER SCALE IS EQUAL TO 0.02 DENSITY
UNITS. (SEVERAL READINGS MAY BE REQUIRED TO INSURE THAT
YOU HAVE READ THE MINIMUM DENSITY WHEN READING NORMAL
NEGATIVES).
(11) RECORD D/MIN (Density Minimum), on a separate sheet of paper.
(12) RECORD D/MAX (Density Maximum), on the same sheet of paper.
(13) SUBTRACT D/MIN from D/MAX. The result is density range (DR).
EXERCISE
The meter force on the densitometer is divided into __________________ density units.
(fill in)
a.
0.2
b.
0.02
c.
0.002
d.
2.00
c. Read base-plus-fog of the film.
d. Record the density value on the sensitometer data sheet in the space marked B+F.
e. Read the lightest area of the sensistrip and record the density value on the sensitometer data
sheet beside the number 21.
f. Read the remaining steps of the sensistrip and record the density values on the sensitometer
data sheet beside Steps 20 thru 1.
