Photograph taken
A photograph is called
The photograph is always held for a moment; the duration of this moment corresponds approximately to the exposure time, ie is between 1/2 and 1/2000 second in commercial cameras; significantly longer exposure times are considered as long-term exposure. With longer exposure times, fast movements can be blurred (motion blur), with shorter exposure times, a movement is increasingly released from its motion context. The discipline of chronophotography makes use of this property of holding moments, in order, for example, to capture excerpts from a movement process and to "freeze" the time. The resulting snapshots can be represented as a sequence of images (series photography), or as a single shot can be completely removed from the context (short-time photography).
The photographic image replaces the picture not only in chronophotography from its context; In addition to holding a moment, decontextualization is also a characteristic feature of photography. The photographer always shows only a more or less consciously selected and designed section (picture design) on his recording. The context of this section, which is recorded on the film, can only be reconstructed to a limited extent, which is why, as a rule, one speaks of decontextualized photography. The attempt to classify the recording back into a (possibly manipulated or fictive) context is called recontextualization. The image can not be enlarged after recording, but the enlargement of the image makes it possible to "pull out" a detail from the shot or to consciously design the side ratio of the trigger.
The aspect ratio of a photograph is 2: 3 (analogue small picture, digital SLR) or 3: 4 (digital compact cameras); if the photographer wishes to design the image during the process of recording for a certain aspect ratio, he must either choose a camera with a different recording format, such as 6 × 6 cm (medium format camera), or insert a mask into the camera; corresponding devices exist, for example, for panoramic photography.
