Photography is able to express all kinds of time that man can sense and be conscious of. The author tries to show how time of nature, time of culture and psychic time co-exist in photographic image which is the result of interactions between man and his surroundings. Included is a review of photography definitions with analysis of how they relate to the notion of time. Discussed are close links between the concept of objectivity in time and photography. On the other hand he points at differences between mathematical and psychological interpretation of time and discusses an usefulness of treating photography as a model. Next the authorI ties to explain the conflict between scientific and artistic uses of photography, taking into account art manifestations at the break of 19th and 20th century where the important problem was how time and movement may be represented. He also explains the ideas of time presence in paintings and how they were adopted in photography. The problem of 'decisive moment' in photography is discussed on that occassion. Next he refers to problems of memory and to the question of how can we identyfy ourselves with the past through photography. In conclusion the author states that defining photography as a model of time or reality misleads us in some respects and finds the term expression much better to explain how time can be felt in our dynamic relations with photography image.
