Fotografēšanās koncepcijas

Kā diafragmas atvēruma iestatījums, aizvara ātrums un ISO jutība kontrolē ekspozīciju

Diafragmas atvēruma iestatījums, aizvara ātrums un ISO jutība ir cieši saistīti ar fotografēšanu. Diafragmas atvēruma iestatījums kontrolē atveri, kas nosaka gaismas ielaidi kamerā, kamēr aizvara ātrums nosaka laiku, cik ilgi atļauts ieplūst gaismai. ISO jutība nosaka ātrumu, kādā filmiņa reaģē uz gaismu. Šie trīs aspekti kopā tiek dēvēti par ekspozīcijas trīsstūri.

Aizvara ātruma, diafragmas atvēruma vērtības vai ISO jutības maiņu var atcelt, pielāgojot pārējos, lai uzturētu gaismas daudzumu. Taču rezultāti mainās atbilstoši iestatījumiem. Piemēram, aizvara ātrums ir noderīgs, fiksējot kustību, diafragmas atvērums var kontrolēt lauka dziļumu, un ISO jutība var kontrolēt fotoattēla graudainību.
