Flosh Synchronizotion

       Correct synchronizotion of the flosh ond shutter opening is obtoined ot oll speeds up,to
'    'l/100 second with Closs " F " floshbulbs. Closs " M " ond M-2 bulbs should be used or 1/25
    second. Electronic flosh units (speedlights) should not be used.
      Every film type hos on ASA Tungsten Index Number. Since floshbulbs use guide numbers for
     determining the f-stop occording to your distonce-from subiect ond shutter speed setting, it  is
    recommended thot you refer to the film ond floshbulb doto sheets.

ACCESSORIES

LENS HOOD, The lens hood provided is o voluoble occessory
ond should be used constontly. lt prevents stroy light from
entering the lens ond helps give pictu res thot crisp look.

FILTERS, Your Neoco 35 lens will give you pictures of excellent
shorpness; but the mood of ,the picture con often be itproved
by using filters.
  Yellow fiilters help bring out clouds ond ore o " must " for
snow scenes ond scenes of seo shore.
  Green filters lighten red colou r ond will bring out greens in
londscopes. Also recommended for outdoor portroits.
  These filters ore for block-ond-white filmswww.butkus.usonly.
