Notice
in this screen the exposure time has exceeded one second, so the “Use timer
now?” choice has been set to “Yes” automatically. If you don’t want to use the
timer, tap on the “No” field.
If you chose the “Check DOF” option, or if you elected not to have the depth of field calculated at all, you will have arrived directly at the screen at right. Here the exposure settings that were calculated from your input data are displayed and, by default, you’ll be offered the chance to change the aperture if you want to. If you elect to make this change you can delete the value in the “Enter Aperture: f/” field and enter a new one using the Graffiti area, or you can increment or decrement the displayed values in half-stop steps by tapping the up/down arrows at the right of the field, or by using the scrolling buttons on the Pilot itself. As you make these changes you’ll see the new exposure values being calculated and updated as you work.
There
will usually be two exposure options displayed in these “Working Data” screens.
By default the recommended exposure setting is listed first and enclosed in a
rectangular box to indicate that it is the choice that will be recorded and
saved in the log file. If you prefer to use the alternate setting and would
rather have it included in the log, tap on it and the box will be shifted to
enclose it.
If
you prefer to alter the shutter speed, tap the “Speed” selection field in the
upper left-hand corner of the screen. That will bring up the screen shown at
left, with the present shutter speed displayed in the “Enter Speed” field. You
may modify the speeds, also, by using the scrolling arrows or buttons, but the
fractional speed values change in full stop intervals. If you want to write in a
specific exposure time using the Graffiti space; enter whole numbers for times
of a second or more
You
can use decimal numbers for fractional speed values or enter fractions in the
Graffiti area. Enter the numerator, then the slash symbol, then the denominator.
To create the slash tap the Graffiti area once to activate the “shift” mode,
then draw a stroke from lower left to upper right. It’s probably preferable to
use the scrolling arrows or buttons for speed changes because they’re fast and
they’ll provide speed numbers that you can use on your shutter. It’s not
generally advisable—and may not be possible—to set your shutter on intermediate
speeds.
Notice that the appropriate average gradient (G-bar) value is included in all
three of these “Working Data” displays. It, too, will be saved in the log file.
Tap “Next” to continue the program.
