HELPFULHINTS





You'll get more enjoyment out  of your
Sunpakif you follow thesehandy tips:
1. Use Alkaline  Batteries. All  brands are
   good. and all give you a lot more f lashes
   than   ordinary   (zinc-carbon  type)
   batteries. Alkalines  hold  their power         Alkaline Battery Numbers
   longer, and are more stable (in warm or        Eveready E-91        BurgessAL-9
   cold weather) than  ordinary batteries.     M a l l o r y M N - 1 5 0 0    N E D A 1 5 A
   While Alkalines are somewhat more ex-       Ray-O-Vac815
   pensive, they  pay  for  themselves in
   greater number of  f lashesand greaterde-
   pendability. (Use of other battery types
   won't hurt your  f lash in any way, but  it
    will mean you'llget fanuerf lashesper set.)
                                                                                                       1 6

2. Check Camera  Controls.  With  cameras      3. Use the Fastest Possible Shutter Speed. lf

4. Use Test  Flash' to Check  Lighting  Ef-
         fects. Your Sunpak can be fired without
        actually exposingf ilm, to let you preview
        a lighting effect. (The feature is handyF         for a final check before taking important
        pictures, too.) How to do: Just pressthe
       'Ready                 Light' window. This  trips the
        flash without exposingany film.
