Consequently, the color reproduced on color film is

CAMERA GRIP AND STANCE

 To obtoin shorp, cleor-cut pictures the comero must
be held immobile when releosing the shutter. When
using the KONICA IttM in the horizontol position, press
 it firmly ogoinst the cheek. When the verticol position
is used, hold it firmly ogoinst the brow. Apply firm but
gentle pressure when pressing shutter bulton. Hold
breoth momentorily to prevenl body movements.
 The construction of the KONICA IIIM permifs, os is
shown in lhe  cuts, o ropid succession of shots in
either the horizontol or verticol position.
 At slow shutter speeds of  less thon    | /30  Sec. use
tripod or other fixed support in coniunction with coble
