O\u010d vlastn\u011b jde?<\/h3>\n

Odrazn\u00e1 deska bude va\u0161\u00edm nejlep\u0161\u00edm p\u0159\u00edtelem p\u0159i fotografov\u00e1n\u00ed klidn\u00fdch p\u0159edm\u011bt\u016f a sc\u00e9n. V prvn\u00ed \u0159ad\u011b je nejsympati\u010dt\u011bj\u0161\u00ed, \u017ee odraznou desku m\u016f\u017eete koupit za p\u00e1r stovek, anebo si ji vyrobit doma, a to t\u00e9m\u011b\u0159 zadarmo. Jedn\u00e1 se toti\u017e pouze o b\u00edlou (p\u0159\u00edpadn\u011b zlatou, st\u0159\u00edbrnou, ale i \u010dernou) plochu, kter\u00e1 odr\u00e1\u017e\u00ed sv\u011btlo pot\u0159ebn\u00fdm sm\u011brem.\u00a0Jedn\u00e1 se o nejlevn\u011bj\u0161\u00ed modifik\u00e1tor sv\u011btla, kter\u00fd existuje. Jej\u00ed hlavn\u00ed funkc\u00ed je dosv\u011btlit fotografovanou sc\u00e9nu.<\/p>\n

 <\/p>\n

Jej\u00ed pou\u017eit\u00ed je v\u0161ak omezen\u00e9 rozm\u011bry; pou\u017e\u00edt ji m\u016f\u017eete pro fotografov\u00e1n\u00ed portr\u00e9t\u016f, makra, produkt\u016f a dal\u0161\u00edch klidn\u00fdch p\u0159edm\u011bt\u016f. Pokud se chyst\u00e1te j\u00edt\u00a0fotit architekturu nebo krajinu (kdy je fotografovan\u00e1 sc\u00e9na tak rozlehl\u00e1, \u017ee n\u00e1m ani ty nejv\u011bt\u0161\u00ed odrazn\u00e9 desky neposta\u010d\u00ed), anebo sport \u010di report\u00e1\u017e (kdy se objekty h\u00fdbaj\u00ed p\u0159\u00edli\u0161 rychle na to, abyste za nimi b\u011bhali s odrazkou a dosv\u011btlovali), nechte odraznou desku doma.<\/p>\n

 <\/p>\n

Prvn\u00ed typickou situac\u00ed, ve kter\u00e9 s\u00e1hneme po odrazn\u00e9 desce, je, kdy\u017e n\u00e1m objekt osv\u011btluje sv\u011btlo z jedn\u00e9 strany (slunce, extern\u00ed blesk aj.). Abychom tento objekt dosv\u011btlily i ze strany druh\u00e9, um\u00edst\u00edme zde odraznou desku, kter\u00e1 sv\u011btlo (ze slunce nebo extern\u00edho blesku) odraz\u00ed zp\u011bt na objekt.<\/p>\n

 <\/p>\n

Dal\u0161\u00ed situac\u00ed, ve kter\u00e9 bude odrazka va\u0161\u00edm nejlep\u0161\u00edm p\u0159\u00edtelem je n\u00e1sleduj\u00edc\u00ed.

V takov\u00fd moment s\u00e1hneme po odrazn\u00e9 desce, um\u00edst\u00edme j\u00ed p\u0159ed modelku (nezapome\u0148te si s sebou p\u0159iv\u00e9st kamar\u00e1da, kter\u00fd v\u00e1m odraznou desku podr\u017e\u00ed!), kterou odraz\u00edme sv\u011btlo slunce zp\u00e1tky do obli\u010deje modelky.
