Transfokacja

Transparency - a photographic treatment based on focal length (zoom) when photographic film is irradiated. It changes the angle of view in the lens, which gives the impression of "flattening the perspective" and less depth of field. In fact, when driving a camcorder, its motion on a wheelchair or trolley, the depth of field or perspective does not change, but the background and the surroundings change.

recommendations

Transparency should be used only in special cases. It should not be used as an effect in itself. For a photo to be taken with the transfocus effect, the photographer should always have the exact composition of the frame from which he / she wants to start the image and the details of the image that he / she wishes to achieve by varying the length of the lens. Technical dependencies

There is, however, a significant difference between transcoding and invasions and departures. Actual camera movements, or front and back camera, are accompanied by a change in the position between the objects in the frame, especially when they are at different distances from the lens. In cameras and compact cameras, transfocations (ie, "zooming") are performed using a lever and are always fluid, although there are exceptions of models with different speeds. In the case of digital SLRs, this procedure is performed manually, using the so-called. the lens on the lens, so that the fluidity and dynamics of the focus shift is dependent only on the operator. Modern use

Transcoding is currently one of the most commonly used film treatments, which are used not only by amateurs, but also by reporters. Meanwhile, its field of application is very limited, due to the unrealistic appearance of approximations and distances. In most film schools the use of this technique is criticized. The only exception is the call to a specific effect - most often a film trick. However, it does have a rather poor effect, so if you do not need to change the focal length during a given shot, it should go away from that form.
