Flash synchronization (original) (raw)
Als Blitzsynchronisation oder Synchronblitz wird das automatische Synchronisieren des Zündens eines Blitzgeräts mit dem Ablauf des Verschlusses bezeichnet. Sie gewährleistet, dass der Verschluss während der Leuchtdauer des Blitzes das volle Filmfenster aufdeckt.

(de) In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor. In cameras with mechanical (clockwork) shutters synchronization is supported by an electrical contact within the shutter mechanism, which closes the circuit at the appropriate moment in the shutter opening process. In electronic digital cameras, the mechanism is usually a programmable electronic timing circuit, which may, in some cameras, take input from a mechanical shutter contact. The flash is connected electrically to the camera either by a cable with a standardised coaxial PC (for Prontor/Compur) 3.5 mm (1/8") connector (as defined in ISO 519), or via contacts in an accessory mount (hot shoe) bracket. Faster shutter speeds are often better when there is significant ambient illumination, and flash is used to flash fill subjects that are backlit without motion blur, or to increase depth of field by using a small aperture. In another creative use, the photographer of a moving subject may deliberately combine a slow shutter speed with flash exposure in order to record motion blur of the ambient-lit regions of the image superimposed on the flash-lit regions. (en) Nella fotografia, la sincronizzazione del flash, o syncro-flash, è la sincronizzazione del lampo del flash rispetto all'apertura dell'otturatore che convoglia la luce sulla pellicola fotografica o sul sensore di immagine. Nelle fotocamere con otturatori meccanici la sincronizzazione è supportata da un contatto elettrico all'interno del meccanismo dell'otturatore, che chiude il circuito al momento opportuno nel processo di apertura dell'otturatore. Nelle fotocamere digitali elettroniche, il meccanismo è solitamente un circuito di temporizzazione elettronico programmabile, che può, in alcune fotocamere, ricevere input da un contatto dell'otturatore meccanico. In un uso creativo, il fotografo di un soggetto in movimento può deliberatamente combinare una bassa velocità dell'otturatore con l'esposizione del flash per registrare il mosso delle regioni con illuminazione ambientale, sovrapposte alle regioni illuminate dal flash.

Em câmeras mecânicas, o mecanismo de sincronização é um contato elétrico conjugado ao obturador. Em câmeras eletrônicas digitais, o flash não é disparado diretamente pelo contato elétrico, mas por um circuito temporizador programável acionado pelo contato. Atualmente, a maioria das câmeras eletrônicas digitais possui um flash eletrônico incorporado ao corpo da câmera sendo que somente câmeras de uso profissional ou semi-profissional ainda possuem contatos para sincronização de flashes externos. (pt) Med blixtsynkronisering i en kamera menas att blixtens ljus sammanfaller med den slutartid under vilken ljuset släpps in i kameran till den fotografiska filmen eller den elektroniska bildsensorn. Ibland används uttrycket ”synktid” för de slutartider som kameran kan användas med blixt. (sv) Синхрониза́ция фотовспы́шки — согласование моментов срабатывания фотовспышки и затвора фотоаппарата, необходимое для полноценного экспонирования импульсным освещением фотоматериала или фотосенсора. Синхронизация может осуществляться вручную на длительной выдержке, или автоматически при помощи синхроконтакта. В фотоаппаратах с механическим или электромеханическим затвором роль синхроконтакта выполняет электрический контакт, который замыкается движущимися деталями. В цифровых фотоаппаратах за синхронизацию чаще всего отвечает центральный микропроцессор.Электрическое соединение затвора с фотовспышкой осуществляется синхрокабелем с коаксиальным PC-разъёмом, через горячий башмак или при помощи синхронизатора, использующего инфракрасное излучение или радиосвязь. (ru) 閃燈同步速度是指相機釋放閃光燈，投射光源至被攝主體後，可完全接收到投射光源的最快快門速度。根據不同相機的品質、性能及使用材質的差異，每台相機的閃燈同步速度都不同，這與相機的製造方法、使用材質、設計目的有關。然而一般來說，多數的專業相機，其閃燈同步速度大約都落在1/250秒以內。此數據可在相機的使用說明書中查到。 (zh) |
