Press
the Power button to turn your Palm Pilot on, then tap the Applications Button
and you should see a screen display similar to this one. There will probably be
other application icons showing, in fact the Display Area may be full of them.
If it is, and if the BTZS icon is not visible, one of the Scrolling Arrows may
be black (active); tap it, or press one of the Scrolling Buttons, to reveal more
application icons.
The Expo/Dev program now has only one icon labeled BTZS,
as shown here. Tap on it to start the program. If you have run the program
previously you will see the screen display you were working with when you turned
the Palm Pilot off.
If
you are running the program for the first time you’ll see the display at left.
This is the first “Constants” screen, as indicated in the “Category” area in the upper right corner of the display. The values you’ll enter in these fields will be retained in memory until you change them.
The “Method” is initially displayed as “Zone.” If you prefer to work with the
Incident System, tap on “Incident” to change the default value. Enter your
holder number in the next field and include other brief identifying symbols if
you want to. You’ll refer to this number when you want to retrieve the saved
exposure data from the Memo Pad, so it should be informative.
Enter
your flare factor; 0.02 is a reasonable number if you’re not sure what to use.
Enter the lens focal length in millimeters (required) then tap on the “Film”
field to display a new screen (at left) which offers you a choice of any of the
film/developer files you have imported from the Plotter program and stored in
memory. They contain exposure and development data taken directly from the
Plotter’s charts as well as reciprocity compensation that you will have been
prompted to select before the files were exported from the Plotter.
Tap on the film of your choice then tap the OK button, and when you return to
the original “Constants” screen and you’ll find your film selection entered for
you.
The
following “Correction” field is provided for your use later if, after using the
program for a while, you discover that it’s consistently producing negatives
that are too thin or too dense. You can correct a consistent exposure error by
tapping on the up or down arrows at the right of the field to enter a correction
value in fractions of a stop. Positive (+) values will increase exposure;
negative (–) values will reduce exposure. Tapping the black dot beside the
scrolling arrows will restore the Correction value to its default value, 0.
The paper ES value is also filled in for you from the value you specified in the
Plotter file. You can also modify this value somewhat (+/-0.05) but if you need
to change it further than that you should return to the Plotter, change the ES
there, then re-export the file to the Palm. Here, too, you can tap the black dot
to restore the default value.
While
you’re on this screen you can call up an “About BTZS” screen by tapping on the
copyright line at the lower left edge. This will display the screen at lower
left, giving the address, Email address and phone number of The View Camera
Store. Contact the company for help in operating this program or for information
about their other products or the BTZS workshop programs.
You
can also access this screen at any point in the program by tapping on the Menu
button in the lower left corner of the Pilot. A Command drop-down menu will
appear offering a choice of “About” or “Help.” The “Help” option provides brief
descriptions of the features of each of the program screens and tips for using
them. You can also access each screen’s “Help” text by tapping on the “i” symbol
next to the BTZS title.
You can jump directly to any of the program screens by tapping on the “Category”
heading (previous page) in the upper right corner of each program screen. A
drop-down list will appear, headed by “Constants,” which you’ve already worked
with; the other Category names identify the various screens that comprise the
program, and suggest their content.
Tap the “Next” button to proceed to the “Data Entry”
screen.
