Abstract
With this apparatus it is possible to adjust the diaphragms of a camera for photographs of the type for instantaneous developing, on the basis of the ambient temperature and in accordance with the characteristic film tables supplied by the film manufacturers. With said apparatus it is also possible to vary the developing time of the photograph depending on the ambient temperature, again in accordance with the abovementioned tables. The ambient temperature is converted into voltage (block 5), amplified (block 6) and the maximum values limited (block 7) and minimum values limited (block 8). It is then compared (block 10) with the time lapsed (block 9). A display (block 14) indicates the modifications to be made to the shutter of the camera. A sound is emitted (block 12) to indicate the end of the developing time. <IMAGE>
