Abstract

Fotografija iz zraka je specifično i zanimljivo područje još od samih početaka

fotografije u 19 stoljeću, kada je Nadar započeo snimati fotografije iz zračnog

balona. S vremenom se iz toga razvila zračna fotografija (aerial photography) i iz

aviona, helikoptera i slično. Pojavom i nastankom drona, čija tehologija se počela

razvijati prvi puta u vojne svrhe, javlja se mogućnost snimanja iz zraka takvom

tehnologijom. Fotografija iz zraka i fotografija dronom općenito ima, pored

ostalog, specifčnost da pokriva scenu izrazito različitih uvjeta osvjetljenja,

odnosno izrazito različitih tonskih vrijednosti, ali isto tako i specifičnost da u praksi

ne dolazi u obzir mogućnost snimanja i izrade pravog HDR-a zbog nemogućnosti

stabilizacije fotografskog aparata u letu. Kao moguće riješenje nameće se

upotreba pseudo HDR tehnike, koja podrazumijeva snimanje scene u sirovom

zapisu te kasniju obradu tj. tonsko mapiranje takvog zapisa. S obzirom na

karakteristike scene, snimane fotografskim aparatom na dronu, potrebna je

specifična obrada, koja može podrazumijevati i tonsko mapiranje pojedinih

djelova snimljene scene kako bi se ispravile „greške“ nastale prilikom snimanja,

odnosno povećao ukupan broj podatka koji se može prikazati takvom

fotografskom slikom. U radu se teoretski analizira tehnologija drona i drona sa

fotografskim aparatom odnosno kamerom, HDR fotografija s posebnim

naglaskom na pseudo HDR fotografiju te se u praktičnom dijelu, temeljem te

analize, izrađuju autorske pseudo HDR fotografije snimane dronom.

Abstract (english)

Aerial photography is a specific and interesting field ever since the beginning of

photography in 19th centuary, when Nadar fist started shooting photos from air

baloon. With time, out of it developed aerial photography from aeroplane,

helicopter and similar. By appereance and emergence of drones, whose

technology firstly started to develop in millitary purposes, the possibility appears

to film from air with that kind of technology. Aerial photography and drone

photography in general has, among everything else, specificity to cover the scene

which has extremely different lightning conditions or tone values but at the same

time, in practice, it is not possible to shoot and develop real HDR because of the

impossibility to stabilise camerain flight. As possible solution, use of pseudo HDR

technic is imposed, which implies shooting the scene in RAW format and later

postprocessing ie. one mapping of that kind of format. Considering the

characteristics of the scene, shot with a photographic camera on the drone,

special processing is required, which may also include tone mapping of the

individual parts of the recorded scene to correct the „errors“ caused during

recording or increase the total number of data that can be displayed with such a

photo. The paper theoretically analyzes the drone technology and drone with a

camera, HDR photography with a special emphasis on pseudo HDR photography

and in the practical part, based on this analysis, authored pseudo HDR

photographs, taken with drone, are created.
