Abstract

Podvodno fotografiranje se močno razlikuje od navadnega fotografiranja in je predvsem strokovno zahtevnejše. Prva podvodna fotografija je bila narejena leta 1893, v Sloveniji pa leta 1938. Uspešna podvodna fotografija je mogoča le s posebno opremo in tehniko. Pod vodo se prav tako lahko uporablja fotoaparate, ki so zasnovani za uporabo na suhem, vendar jih je potrebno zaščititi s posebnim vodotesnim ohišjem. Glavna težava pri zajemanju fotografij pod vodo je izguba barv in kontrastov, še posebej pri večjih globinah. Izguba barv ne narašča samo z globino, tj. z vertikalo, temveč tudi po horizontali. Podvodni fotografi se težav z izgubo barv lotevajo na dva načina – tako, da se objektu skušajo čim bolj približati, pri čemer uporabljajo širokokotne ali makro objektive, ki imajo točko ostrenja zelo blizu objektiva. Drugi način, s katerim si pomagajo pri ohranitvi barv, je uporaba bliskavice. Na ta način zagotovijo poln spekter svetlobe, ki objekte primerno obarva. Z množičnostjo tovrstnega fotografiranja se je, zlasti na spletu, pojavilo zelo veliko podvodnih fotografij, ki so z vidika strokovnih kriterijev pogosto slabše kvalitete. Obstajajo namreč kriteriji, ki natančno opredeljujejo kvalitetno podvodno fotografijo.

Secondary title:	UNDERWATER PHOTOGRAPHY
Secondary abstract:	Underwater photography is different than ordinary photography and is also more expertly demanding. First underwater photograph was taken in the year 1893, in Slovenia that happened in 1938. If you want to be successful in underwater photography, you need specialized equipment and techniques. Cameras that are intended for the use on land can also be used under water but they need to be protected by special waterproof housing. The main problem when taking photographs under water is the loss of colour and contrast. This especially happens in great depths. The loss of colour does not increase only with depth – vertically but also horizontally. Underwater photographers deal with this problem in two ways. The first option is to get as close to the object as possible by using wide-angle lenses or macro lenses. The second option, which helps to preserve the colour, is the use of flash. By using flash we ensure full – spectrum lighting which gives the objects appropriate colour. Because underwater photography is becoming increasingly popular, its quality is decreasing. The quality of underwater photography can be determined by precise criteria.
