Fotograferingsbegrepp

Bländare

Bländaren, en öppning som kontrollerar mängden ljus som går in i kameran, är en av de tre faktorer som bestämmer exponeringen. Bländarhuset innehåller tunna metallplattor som öppnar och stänger för att släppa in ljuset genom bländaren och in i kamerna. Bländarens storlek har ett nära samband med fotots ljusstyrka: ju större bländare, desto ljusare foto; ju mindre bländare, desto mörkare foto.

Storleken på bländaren betecknas av ett värde som är känt som ett “F-nummer.” F-numret betecknar brännvidden dividerat med objektivets diameter. Om, till exempel, ett objektiv med 50 mm brännvidd har f-numret F2, är diametern på bländaren 25 mm (50 mm/25 mm=F2).

Ju mindre f-nummer, desto större storlek på bländaren.

Bländarens öppning beskrivs som exponeringsvärdet (EV).

Om exponeringsvärdet ökas (+1 EV) betyder det att mängden ljus fördubblas. Om exponeringsvärdet minskas (-1 EV) betyder det att mängden ljus halveras. Du kan även använda funktionen för exponeringskompensering för att finjustera mängden ljus genom att dela in exponeringsvärdena i underavdelningar 1/2, 1/3 EV, osv.
