Judit Berta Varga: Jenő Cholnoky as Photographer - He conscious use of the camera
the geologist Ferdinand V. Hayden from 1870 on 's, as a paid employee of the research group investigating the Grand Canyon and the Yellowstone River. During the photographic work, which required patience, stubbornness, and was accompanied with many hardship, Jackson was able to produce his first good photograph only on the third day - first, because of the stormy wind, then because of the damaged bowl containing the silver nitrate. Later on, he was less successful, for the horse carrying the camera stumbled and destroyed his camera. In the age of the contact copies our national photographers had to encounter similar difficulties. Károly Divald Senior, who was a leading character in portraying the Tátra, started his journey with a numerous staff and heavy luggage. To be able to take photographs in different sizes, he had to carry cameras of 25-30 kilogrammes each beside the instruments for developing. While the master was busy himself with the preparation of the sheets of glasses in the darkroom tent - which turned out to be an extremely sensitive operation because of the fragility of the collodium layer - , the valley became covered with rnilkwhite fog, therefore frustrating the photographer's original intention. The unexpected weather conditions did not discourage him from taking landscape photographs though. Later on, he made so beautiful pictures for albums about the peaks of the Tátra, about its tarns wedged inbetween, about the veil-soft waterfalls submerging from its cliffs, that their composition became an example worth following for other landscape photographers, particularly for those who studied the rapidly developing discipline of geography. Lajos Lóczy Senior took photographs in the 1880s in the Transylvanian Carpathians, in which - with the representation of the socalled Staffage shapes - Divald' s settings reoccur. The characteristic settings of the accompanying colleagues and students can also be observed in Cholnoky's high-mountain pictures taken 20 years later. The question about why Cholnoky did start his journey on 21 November 1896 with glass-sheet camera requiring a large space, could be answered only by guessing. The preponderance of the contemporary glass negatives in the collection of the Historical Photography Department in the Hungarian National Museum and the similar number of negatives owned by the Department of Physical Geography at the Eötvös Loránd University - deposited in the museum - supports the belief, that Cholnoky's group similar to the majority of the amateur photographers travelling around the world - had worked onto sheets of glasses till the 1910s. It is true, that the use of the bromine-silO f7 O
