<\/a>Shutterul ghilotin\u0103 este asemenea unei u\u0219i glisante care p\u0103trunde printr-un spa\u021biu dedicat dintr-o parte \u00een alta (de sus \u00een jos). Este o variant\u0103 care se folosea pe timpuri \u0219i se baza \u00een special pe for\u021ba gravita\u021bional\u0103. Viteza de expunere era dat\u0103 de lungimea unui spa\u021biu transparent din mijlocul u\u0219ii, aceasta fiind, practic, distan\u021ba dintre zonele mate.<\/p>\n <\/p>\n
Shutter rotativ<\/h3>\n
Camerele ieftine, de tip cutie, sunt echipate, de obicei, cu shuttere simple, rotativ. Acesta avea o manet\u0103 de declan\u0219are, un arc \u0219i un placa sub\u021bire, rotund, cu o gaur\u0103. C\u00e2nd era declan\u0219at, arcul rotea placajul, iar\u00a0 gaura se alinia cu apertura. \u00cen acest moment, lumina p\u0103trunde pentru o frac\u021biune de secund\u0103 \u0219i expune filmul.<\/p>\n
Sisteme de control \u0219i func\u021bionare pentru shuttere<\/h2>\n
Pentru controlarea unui shutter se folosesc c\u00e2teva sisteme \u00een camerele clasice.<\/p>\n
Mecanic<\/h3>\n
Un arc care \u201etrage cortina\u201d este eliberat automat la declan\u0219area shutter-ului, iar timpul este controlat mecanic.<\/p>\n
Mecanic hibrid<\/h3>\n
Un arc este declan\u0219at mecanic prin declan\u0219ator, iar timpul este controlat electronic.<\/p>\n
Electric hibrid<\/h3>\n
Un arc este eliberat eletromagnetic prin declan\u0219atorul shutterului, care este de fapt un \u00eentrerup\u0103tor un \u00eentrerup\u0103tor. Evident, timpul este controlat electronic.<\/p>\n
Electric<\/h3>\n
Cortina se trage electromagnetic c\u00e2nd se apas\u0103 pe butonul shutterului. Aici declan\u0219atorul este, de fapt, un \u00eentrerup\u0103tor pentru un motora\u0219 orizontal.<\/p>\n","protected":false},"excerpt":{"rendered":"

<\/a>\u00cen unele camere de fotografiat, diafragma shutterului frunz\u0103 \u0219i diafragma care define\u0219te apertura expunerii sunt identice. Atunci, lamele deschise ale shutterului contureaz\u0103 o gaur\u0103 poligonal\u0103 cu diametrul aperturii selectate. Se pot atinge viteze mult mai mari prin limitarea aperturii la dimensiuni mai mici \u0219i viteze mai mari daca dimensiunile sunt mai mari. Totu\u0219i, \u00een cele mai multe cazuri se folosesc dou\u0103 diafragme \u00een spatele obiectivului. Astfel, shutterul are mai pu\u021bine \u201efrunze\u201d, dar este mult mai rapid \u0219i poate cuprinde \u00eentreaga apertur\u0103.<\/p>\n
