fine-grain emulsion ensures negatives from which big enlargements can be made (ASA 80 . BS 30 °).

Panatomic-X Film: A high-definition panchromatic film giving exceptional image sharpness by virtue of its thin coating, very fine grain, and freedom from halation and light-scatter. Ideal for negatives permitting a high degree of enlargement, especially when developed in Kodak High Definition Developer (ASA 25 . BS 25 ").

Tri-X Pan Film: A panchromatic film of very high speed. It is ideal for snapshots in very poor light outdoors, for flash snaps in large rooms, for taking pictures by Photoflood light, and for "available-light" photography (ASA 200 • BS 34 ").

Flash shots with the RETINA automatic I

Slide your flashgun, for instance the KODABLITZ, into the accessory shoe of your camera, plug the flash cable into the flash socket (o), and set the required distance.

Disconnect the automatic exposure control and set the aperture (F/no.) as required. The aperture is dependent on the guide number of the flash bulb or electronic flash unit used and the distance set.

The guide number is specified on the packages of flash bulbs and in the operating instructions for electronic flash units. The following rule applies:

Guide number divided by distance aperture

If, for instance, your guide number is 72 and your distance 6.5 ft., 72 6.5 = approximately 11.

This means that you have to turn the shutter ring (p) until the red aperture figure 11 of the flash scale (marked in red) is opposite the setting mark (q). The shutter speed in the flash range is always '/30 second. You are now ready to take a flash shot.

Time exposures are possible too
