DARKROOM AUTOMATION F-STOP, Instruction Manual

Page: 7 / 26

• Drydown adjustment -
% 0
- percentage decrease in exposure to
compensate for print darkening when drying. Only active if drydown has been
enabled in setup mode.
To speed cycling through the basic menu, some items -
m 1
,
j0.0
and
% 0
-
are skipped after a base exposure has been made - just cycle through the menu
one more time to see them.
The factory default settings enable memory mode, paper speed adjustment and
drydown.
From basic mode you can:
Enter memory mode by holding down the menu key when the memory selection
-
m 1
- is showing.
Enter setup mode from the other basic mode displays -
2.0
,
d0.5
,
b1.0
etc.
- by holding the menu key down. Seconds mode is accessed via setup mode.
Base Exposure
Turn the timer on with the power switch. The display will show
2.0
stops. The
burn, test strip, and dodge times will be reset to their nominal values. The safelight
will be on and the enlarger off. The safelight is always on if the enlarger is off and
vice-versa.
The steps in making the base exposure are:
1. Focus by holding the expose key down until the enlarger turns on and the
safelight turns off. The display will show
Foc.
. Tap the expose key to turn the
enlarger back off.
2. Set the exposure with the up and down keys. The display will show
2.0
,
2.1
,
2.2
... Holding the key down ramps the setting.
3. Press the expose key to start the exposure: the enlarger turns on, the safelight
turns off and the display counts down the remaining seconds.
Dodging
The timer automates the timing of one or more dodges. It can seperate multiple
dodges into a set of progressive dodges so that they all fit into the base exposure
time. Without this feature a 1.0 stop dodge and a 1.5 stop dodge would require
holding back 50% of the exposure for the first dodge and then attempting to hold
back 65% for the second dodge when only 50% of the print time remains.
