Thyristor  ehergy savings and         - automatic flash





 Automatic or computer electronic flash units control exposure by controlling the
 amount of time the flashtube is on. At long flash-to-subject distances, the  f lashtube
  is on for long periods of time. As you move your flash closer to your subject, the
 flashtube is on for shorter periods. But, the exposure remains the same as long
 as the flash is within the prescribed shooting range. This eliminates constant
 adjustment of your camera lens opening for each different shooting distance.
 You use just one lens opening over the automatic distance range you choose.
 The period the flashtube is on is controlled by the flash computer. The computer
 monitors the light reflected from the subject, adding  it up until a predetermined
 amount is reached. At this time, the computer turns off the flashtube to controt
 the exposure.
 Computer controlled electronic flash units that do not have thyristor energy saving
 circuitry waste the energy not used for a particular flash. Thus, whether the flash-
 tube is on for a long or a short time, all the remaining energy is wasted. Each time
 the flash unit is fired, it has to start from zero and build up the required energy
 level for the next flash, requiring long recycle times and needlessly exhausting
 battery energy.
Your Honeywell 7805, however, stores the energy not used and uses it for the
next flash. This gives you super-fast recycle time (up to 0.9 seconds between
flashes) and more flashes per battery charge. you may get as many as 7s0
flashes  if all your shots are at close range when using internal Nicad batteries.
Here's how. Four different shooting distances are shown in the chart on page g.
Each example uses  f /2.0 as the constant lens opening. Note in the first chart that
the flash-to-subject distance is 29 feet (8.8 meters) and B0% of the flash energy is
used. The corresponding recycle time is 8 seconds and the number of flashes per
battery charge is about 90.
It's all relative! Look at the other charts and note the energy saved, with resulting
shorter recycle times, plus increased flashes per battery charge as the shooting
distance becomes shorter.





                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             I

You can use the AC Adapter/Charger  (13) as an AC power source for your 7803
and to charge internal Nicad batteries. lt's ideal for forming the storage capacitor.
 lf an AC outlet is handy, use it in your picturd-taking situation. lt's particularly
good for constant use needs such as studio photography.
Use it on either 120 volts AC (Standard U.S.A.) or 240 volts (many European and
other countries).
The AC Adapter/Charger must be set to the line voltage you will use to prevent
damage or improper operation. To set, use a ballpoint pen or similar object posi-
tioned in the slot as shown in the picture below. Push the switch in the direction
of the voltage indication you want to use, either 120V or 240V. For your conven-
ience the AC Adapter/Charger has been factory set to 120V position and provided
with a standard (u.s.A.) plug. A wall ouflet AC plug adapter may be necessary
in some countries.

    Charging internal Nicad batteries
    How to charge
      To charge, insert internal Nicad battery tray withrinJernal batteries (page 13).
         Set voltage selector on AC Adapter/Charger as described on page 10. Set opera-
         tion switch (12) to off "O". See below for more information on care and use of
         the battery                                             ,            r
     Before first use
       Because of shelf-life discharge, you should charge internal Nicad batteries for
        at least three hours before you use your unit the first time. lf time permits, an
         overnight or 24-hour charge is recommended. lt will improve performance.
fl
    How often to charge
            It's good practice to charge the batteries after each use. The batteries must be
        charged when the recycle time is 30 seconds or longer.
       The batteries discharge when they are not charged periodically or if stored at
HI       temperatures above 95 degrees Fahrenheit (35 degrees centigrade). To keep your
       7805 ready for instant use, charge the batteries for 3 hours at least once every
        30 days.
     Don't overcharge
         Internal Nicad batteries are fully charged after only 3 hours of charging. Do not
        continuously charge them longer than 72 hours. You may damage the unit.
         lf you forget
               lf you haven't charged the batteries for longer than 6 months, or if you forget and
        leave your 7805 turned on, charge the batteries for a full 24 hours. lf they do
        not seem recovered, discharge and recharge again in this manner. Turn on your
         flash unit and let it idle for about 172 hours. Don't flash  it during this time! Then
       charge for a second 24-hour period. Discharging and recharging 2 or 3 times
        should recover the batteries.  lf the batteries are not recovered after 3 cycles of
        discharge followed by 24-hour charges,  it's time to see your dealer or one of
        Honeywell's Service Centers. You may need new batteries.
      AVOID storing or charging your 7805 at temperatures in excess of 95 degrees
        Fahrenheit (35 degrees centigrade). To do so will cause the battery to accept a
        limited charge. To obtain normal battery operation again, charge for at least 3
        hours at temperatures below 95 degrees.
      WARNING: Do not operate your 7805 if the ready light takes 30 seconds or more
         to glow. Gharge the batteries and then operate your 7805.

The number of flashes you'll get from each battery charge is not fixed.  lt depends
upon how you use your unit.
The number of flashes varies with the state of charge of the batteries, condition of
the storage capacitor (see page 13), idle time between flashes, temperature, and
flash-to-subject distance if you're using your flash unit in the automatic mode.
However, flash-to-subject distance is not a factor when you're using your flash
unit in manual (non-thyristor) mode.
For example, if you're firing at the rate of one flash every four minutes you'll get
less  f lashes per charge than if you fired at two per minute.
Leaving the unit on constantly drains energy from the batteries. So if convenient,
turn off your flash  if there is likely to be more than a minute between flashes.
The chart below shows flash per charge for manual (non-thyristor) operation on a
typical unit using internal Nlcad batteries. The data was derived by the flashing
of the unit every 30 seconds until the recycle time exceeded 30 seconds.
CHARGE TIME           30 Min.     1 Hr.      2 Hr.      3 Hr.
NUMBER OF FLASHES 13     26     55        90
Depending upon conditions you may get slightly less or slightly more flashes with
your unit. So use the chart as a guide. Remember, that the automatic thyristor
features give you many more flashes than shown in the chart.

How to determine your own
  guide number
                                                                                                                                                              'f     r
   A guide number is simply what the word implies. lt's a guide for manual flash
      photography. The guide numbers we suggest for your flash are listed in the chart
    on page 18. Note that there is a separate guide number for each film speed listed.
    There are many factors that affect expbsure. These include variations in flash
      units, cameras, processing techniques, film tolerances, subject reflectivity, size
     of room, etc.
     Experience and your personal taste may suggest more or less exposure than our
     guide numbers call for.
     So, to get the results that suit you best, here's how to determine your very own
     guide number:
          1. Load your camera with transparency slide film. We recommend slide film
         because the manufacturer's tolerances and processing techniques are
           usually closer than negative film. And, slide film usually has less exposure
             latitude.
          2. Hold camera exactly 10 feet from a model. The model should be typically
          dressed and in a room that is typical for your situation.
          3. From the chart on page 18, select the guide number for the film you're
           using. Divide the guide number by 10 to get your first trial f/stop. EXAMPLE:
         Guide number for ASA 25 film is 90. Thus 90 divided by 10 is equal to 9. So
            set your camera at the Vz click stop betweenf /8 andf /11.
           4. Set your trial f/stop on your camera. Mark the f/stop for each shot on a card
         and put it in your scene.
           5. Take one picture at your first trial f/stop. i
      I       6.Using this basic method, make additional exposures atVz t/stop larger, one
+          f/stop larger, th l/slop smaller, and one f/stop smaller.
 I
      I         7. Now process the film and select the aperture adjustments that suits you best.

Tips for using your Auto/Strobonar





     Try to line up a group so that everyone is about the same distance from your
      Auto/Strobonar.
      Try to keep your subject a few feet from the wall. This will keep the harsh shadows
      out of your pictures.
e     Avoid shooting through doorways or against windows where objects close to your
       field of view may reflect light into the sensor, causing incorrect exposure.


 I     Bounce flash  Use non-automatic mode for bounce flash. Remove  f lash fromo                  -      your camera and allow two full stops more exposure to compensate for the light
     absorbed by the ceiling or wall under average conditions
      Stop-Action   The fantastic speed of your computer flash (1/50,000 to 1/500                  -      second) is excellent for such stop-action pictures as breaking a light bulb, hitting
     a golf ball, and bursting a balloon. Creative pictures of this type require special
      techniques. Usually the camera shutter is set to "8" and a sample switch (made
      of aluminum foil, paper clip or pieces of wire) is used to fire the flash at the
     moment you desire to make the exposure. Be sure to photograph your subject in
      a dark area and fire the flash when the shutter is open.
     Outdoor use for fill-in light - Your Strobonar can be used quite simply in manual     mode as fill-in light when sunlight causes heavy side or front shadows.
      Spare sync cord - since sync cords are a major reason for electronic flash failure,       carry spare (tested) sync cord with you on all assignments.
     Sync cord tip conneclors - Make sure removable sync cord tip connectors are
        tight, check often.
