Je\u0161t\u011b p\u0159edt\u00edm kdy\u017e jsem fotil nap\u0159 potok ze stativu a vytvo\u0159il tak n\u011bkolik fotografi\u00ed ze stejn\u00e9ho m\u00edsta, bavil jsem se p\u0159ep\u00edn\u00e1n\u00edm fotografi\u00ed v prohl\u00ed\u017ee\u010di vytvo\u0159en\u00edm jak\u00e9si animace. Nenapadlo m\u011b tenkr\u00e1t vytvo\u0159it z podobn\u00fdch fotografi\u00ed video. K tomu jsem do\u0161el a\u017e p\u0159i instalaci webkamery do okna s ukl\u00e1d\u00e1n\u00edm sn\u00edmk\u016f na HDD. Z nich jsem pozd\u011bji vytvo\u0159il kr\u00e1tk\u00e9 video, kde cel\u00fd den utekl b\u011bhem n\u011bkolika minut. Ani jsem nev\u011bd\u011bl, \u017ee jde vlastn\u011b o timelapse, tenkr\u00e1t tato discipl\u00edna nebyla je\u0161t\u011b v kurzu.<\/p>\n

Ob\u010das s fo\u0165\u00e1kem vylezu na balkon lovit blesky p\u0159i letn\u00edch bou\u0159k\u00e1ch.

Hezk\u00fd \u010dl\u00e1nek o timelapse fotografii naleznete ve Fotografii<\/a> z \u00fanora 2013 a na netu spoustu vide\u00ed pro inspiraci. V \u010dasopise je zmi\u0148ovan\u00fd p\u0159edev\u0161\u00edm – jak j\u00e1 \u0159\u00edk\u00e1m – druh\u00fd level timelapse fotografie, timelapse s vyu\u017eit\u00edm pohybu fotoapar\u00e1tu. \u0158e\u0161eno pomoc\u00ed r\u016fzn\u00fdch ly\u017eic, \u010di desek s kole\u010dky. To do timelapse fotografie p\u0159in\u00e1\u0161\u00ed dal\u0161\u00ed rozm\u011br.<\/p>\n

V\u0161eobecn\u011b je pro fotografa v\u00fdhodn\u00e9, aby sv\u011bt vn\u00edmal rovnou fotograficky. Jednodu\u0161e \u0159e\u010deno, proto\u017ee je fotografie (a „ne3D“ video) dvourozm\u011brn\u00e9 medium, znamen\u00e1 to, \u017ee je pot\u0159eba sv\u011bt vn\u00edmat dvourozm\u011brn\u011b. Zjednodu\u0161en\u011b \u0159e\u010deno, kdy\u017e v\u00e1m za objektem roste strom, ve 3D sv\u011bt\u011b to \u010dlov\u011bk lehce p\u0159ehl\u00e9dne, ve 2D sv\u011bt\u011b v\u0161ak strom poroste p\u0159\u00edmo z hlavy. Do fotografick\u00e9ho vn\u00edm\u00e1n\u00ed sv\u011bta je v\u00fdhodn\u00e9 vpravit i t\u0159et\u00ed rozm\u011br, v tomto p\u0159\u00edpad\u011b ale nep\u016fjde o hloubku, n\u00fdbr\u017e o \u010das. Mysl\u00edm to tak, \u017ee je pot\u0159eba vn\u00edmat sv\u011bt tak, jak bude vypadat fotografie po\u0159\u00edzen\u00e1 v r\u016fzn\u011b dlouh\u00fdch \u010dasech (pom\u00edj\u00edm dal\u0161\u00ed nastaven\u00ed fotoapar\u00e1tu). Ide\u00e1ln\u00ed pr\u00e1v\u011b pro timelapse fotografii, ale zdaleka ne jen pro ni. V\u017edy je samoz\u0159ejm\u011b pot\u0159eba \u0159e\u0161it krom\u011b toho co popisuji je\u0161t\u011b spoustu v\u011bc\u00ed okolo, ale to se prax\u00ed dostane do krve ka\u017ed\u00e9ho fotografa.<\/p>\n

Tak\u017ee jako prvn\u00ed po\u0159\u00e1dnou timelapse fotografii bych r\u00e1d rovnou ud\u011blal video, kde se kamera pohybuje. Nejsem velk\u00fd p\u0159\u00edznivce n\u00e1kupu techniky kter\u00e1 toto umo\u017en\u00ed, nebo alespo\u0148 zjednodu\u0161\u00ed, tak n\u011bjak „\u010desky“ se to sna\u017e\u00edm \u0159e\u0161it „samodomo“ metodou. Netvrd\u00edm, \u017ee je lep\u0161\u00ed, nakonec se leckdy uk\u00e1\u017ee jako mnohem n\u00e1ro\u010dn\u011bj\u0161\u00ed jak \u010dasov\u011b, tak n\u00e1klady. Ale tak n\u011bjak to pot\u011b\u0161\u00ed \ud83d\ude42<\/p>\n
