TM 5-3610-257-14
NOTE
•
Shadow densities greater than 1.95 are set in by counting the clicks of the flash dial. Each click
past 1.95 adds .05 up to .10 of basic screen range.
•
If shadow density is less than .05 higher than basic screen range, the instrument will automatically
switch from flash to main (see Short Range Copy).
•
If NO FLASH is turned past lamp marked FLASH TEST while setting dial, instrument will
automatically switch from flash to main.
(4)
Locate density (step 3 above) within .05 on flash dial; set this number opposite lamp that is lighted on
left side of flash dial.
NOTE
The exposure control instrument will compute proper ratio and total exposure time for the two
separate exposures to match copy range to screen range.
(5)
Make an exposure using recorded time units for main and flash.
(6)
For very high highlight and shadow densities, see paragraph 3-6.2j.
o.
Short range copy (gray screen). When highlights are dark and shadows are much lighter than normal, a
change in basic screen range to match short copy range is needed.
