Getting a depth of field despite using a wide aperture:

Despite what was previously mentioned about the factors by which it is possible to obtain a large depth of field, it is seen that the results obtained may not reach the degree of accuracy. On the other hand, we find that in order to obtain depth in the field by narrowing the aperture of the diaphragm, we must lose the advantage of benefiting from the shutter speed. This was one of the problems faced by factories producing photocopiers, and Linhof factories were able to "make significant improvements in the photocopier industry they currently produce. These improvements would overcome the previous problem, and other problems. These improvements were built on scientific theories Salima makes the back of the camera a swinging back, and the lens is designed on a base that can also swing. Swinging Lens Standard (Fig. 43)

Below we show the value of these advantages when photographing ...

(First): To obtain a large depth of field while taking advantage of the wide aperture at the same time, which is not possible with the usual cameras.

(Second): To fix the error in the perspective of the image, and we will come back to talk about it later.
Linhof factories kindly gave us the right to publish and use the published research in this regard.
