20.500.12556/RUL-130378 Vpliv svetlobe na zaznavo opazovalca na fotografiji The impact of light on the preception of the observer on photography V diplomskem delu smo analiziral vpliv svetlobe na zaznavo opazovalca na fotografiji. Primerjali smo vpliv tople, nevtralne in hladne svetlobe, uporabljene na fotografiji, na opazovalčevo zaznavo, spremembo v čustvenem stanju občutke in razpoloženje. V teoretičnem delu so predstavljeni svetloba na splošno, vrste svetil s poudarkom na umetnih svetilih, vrste svetlobe, fotografija na splošno in tudi kadriranje fotografije. V eksperimentalnem delu se je s fotoaparatom Nikon D7500 izdelalo fotografije z uporabo različnih vrst svetlobe. Slike so se v post produkciji še dodatno obdelale za podarjanje učinka tople in hladne svetlobe. Obdelane fotografije so se uporabile kot slikovni material ob anketi. Anketa je večinsko izdelana iz vprašanj zaprtega tipa. Zbrani podatki so bili opisni oziroma kvalitativni. Rezultati ankete so bili obdelani in primerjani s predhodno postavljenimi hipotezami oziroma predvidevanji. Hipoteza 1 je bila na podlagi zbranih rezultatov potrjena. Ta je namreč predvidevala, da različne vrste svetlobe na opazovalca vplivajo različno. Opazovalcem so se prikazovale enake mimike obraza, osvetljene z različno svetlobo. Njihova naloga je bila, da izmed spodaj naštetih čustvenih stanj izberejo najustreznejšega. Izkazalo se je da so različne vrste svetlobe povzročile različno asociacijo čustvenih stanj pri opazovalcih. Prav tako so rezultati anketnega vprašalnika potrdili hipotezo 2. Ta je predvidela, da topla svetloba na opazovalca vpliva bolj pozitivno v primerjavi s hladno svetlobo. Opazovalcem se je prikazoval par fotografij, eden osvetljen s toplo in eden s hladno svetlobo. Njihova naloga je bila izmed para fotografij izbrati najustreznejšo za dano čustveno stanje v navodilih. Izkazalo se je, da so opazovalci večinoma izbrali fotografije osvetljene s toplo svetlobo, če je bilo čustveno stanje v navodilih pozitivno, npr. veselje. Rezultati anketnega vprašalnika so ovrgli hipotezo 3. Ta je predvidevala, da se bodo opazovalci odločili, da je za splošno uporabo najprimernejša nevtralna svetloba. Rezultati pa so pokazali, da se je opazovalcem za splošno uporabo zdela primernejša topla svetloba. Opazovalcem so se prikazale tri fotografije, osvetljene s toplo, nevtralno in hladno svetlobo. Njihova naloga je bila izbrati najustreznejšo fotografijo za splošno uporabo. In the thesis, the influence of light on the perception of the observer in photography was analyzed. The comparison, of the influence of warm, neutral, and cold light used in a photo on the observer's perception, change in emotional state, feelings, and mood, was analysed. In the theoretical part, light, in general, as well as types of lighting with an emphasis on artificial lights, types of light, photography, in general, and framing photography, was presented. In the experimental part, photos were taken using different types of light with Nikon D7500. Furthermore, the pictures were edited in post-production to give the effect of warm and cold light. The processed photos were used as a picture material for the survey. The survey was mostly made from closed-ended questions. The data obtained were descriptive or qualitative. The processed results of the survey showed that neither warm nor cold light was comfortable to look at but an approximation of average daylight. Hypothesis 1 was confirmed based on the collected results. This presupposed that those different types of light affect the observer differently. Observers were shown the same facial expressions illuminated with different lights. Their task was to choose the most appropriate of the emotional states listed below. It turned out that different types of light caused different associations of emotional states in observers. The results of the survey questionnaire also confirmed Hypothesis 2. This, in turn, predicted that warm light had a more positive effect on the observer compared to cold light. Observers were shown a pair of photographs, one illuminated by warm and one by cold light. Their task was to choose from a pair of photos the most appropriate for a given emotional state in the instructions. It turned out that the observers mostly chose photographs illuminated by warm light, insofar as the emotional state in the instructions was positive, e.g. joy. The results of the questionnaire refuted Hypothesis 3. This assumed that observers would decide that neutral light was the most suitable for general use. The results, however, showed that observers found warm light more suitable for general use. Observers were shown three photographs illuminated by warm, neutral, and cold light. Their task was to select the most suitable photograph for general use. fotografija svetloba vpliv zaznava občutki photography light effect perception feelings true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2021-09-14 09:00:12 2021-09-14 09:00:15 2022-09-09 04:16:09 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 81540 7697.pdf 7697.pdf 1 207619CF0E433FD74477C85155FE17E4 3e6f68aa2a240ed44c238438cd4e928545ee6b224649d6130ac4cbb9022683f7 27f351aa-1529-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147475 Naravoslovnotehniška fakulteta 0 0 0
