• a coupled rangefinder,
• bright-line viewfinder,
• exposure value shutter,
• and a high-speed colour-corrected anastigmatic lens of maximum definition.

From now on the exposure value setting should not be altered and only the milled shutter speed ring may be turned (see lower illustration).

The thus determined exposure value setting can be used as long as the lighting conditions remain the same.

Let us once more summarise the most important points of this chapter: Determine and set the exposure value, release exposure value key, turn the milled ring to set the pictorially most favourable combination opposite the triangular mark; then the camera will be ready for action.

For a quickly moving object on the other hand you should use a fast shutter speed to avoid blurring (such as ¹/₅₀₀ sec. and f. 2.8, shown on the previous page).
In the first case a slower shutter speed is chosen in favour of a small aperture and in the second case a larger aperture is selected to enable the use of a faster shutter speed.
You may sometimes obtain exposure value readings on the exposure meter which lie between two numbers. These can also be set on the camera with the diaphragm ring, but shutter speeds should never be set so that the triangular mark lies between two speeds. You can easily avoid this, however, because each setting on the large milled ring has a click stop.

In such cases place the camera on a firm support, preferably on a tripod, attach a cable release (if possible with time lock) to the connection provided and make the exposure. The shutter stays open as long as pressure is exerted on the cable release button.

The apertures required are given in instructions attached to each flash bulb carton.

When using an electronic flashgun the lever must always be set to X. Contrary to flashbulbs any shutter speed can be used. Apertures are calculated from the guide numbers for the flashgun concerned, e. g. guide number 96 divided by a distance of 12 feet = aperture f. 8. The electronic flashgun can be used for black and white or daylight colour films.

Hold the camera steady to obtain sharp results. We advise you to take your Super Silette in both hands and form an angle with your arms against your body. Your thumbs should lie along the back of the camera with the forefinger of your right hand on the shutter release. Line up your subject in the viewfinder. Everything within the luminous frame area will appear on the picture. If you can see only part of the frame, this indicates that you are tilting the camera or not looking through the centre of the viewfinder. As soon as you are satisfied with what you see, press the shutter release; this is done by slowly pressing down the release lever as far as possible with your finger tip.,For subjects nearer than 7 feet use the two short lines

When holding the camera upright turn it to the right or left as desired and operate the shutter release either with your middle finger or thumb, depending on the camera's position.

Photographs without a tripod should only be taken with shutter speeds of ¹/₆₀ to ¹/₅₀₀ sec., possibly ¹/₃₀ sec. too. If you have a steady hand you may be able to avoid camera shake at ¹/₁₅ sec. by supporting your elbows somehow, but you must try that out for yourself.

We already mentioned large and small lens apertures (on page 8) in the choice of suitable shutter speed and aperture combinations.

If the shutter speed initially selected gives an exposure reading in which the aperture can be set on the red dot between f. 8 and 11 or on f. 11 you can use the so-called snapshot or zone focusing setting.

This method is used for close-range and long distance photographs where you want to avoid focusing the camera at all.

Exact particulars of the depth of field obtainable at various apertures and distances can be seen from the table on pages 26/27.

Sometimes you want to be in the picture yourself. Your Super Silette provides for this wish with its delayed action release. First place the camera on a tripod or other firm support and then set the lever (No.2 see main illustration) at "V" after the film has been wound on. As soon as you press the shutter release the small lever starts to move and operates the shutter automatically after about 7 seconds. The lever always returns to its original position and has to be re-set for every delayed action shot. Any of the instantaneous shutter speeds can be used with it, and those for flash. Time exposures (= B setting) cannot be made with the delayed action release mechanism.

Before we explain how to load your Super Silette with film, here are a few hints on different kinds of film.
First of all there is Agfa Isopan F, 40 ASA (17° DIN), a universal film of medium speed. It is a sharp, fine-grain film from which you can obtain good enlargements. In bad weather Agfa Isopan ISS, 200 ASA (21° DIN), is the right film. It allows you to use instantaneous shutter speeds or, when the sun is shining, smaller apertures to obtain greater depth of field.
