Terminu skaidrojums

Optiskā tālummaiņa

Šī ir vispārīga tālummaiņa, kas tiek panākta ar objektīva palīdzību un nesamazina attēlu kvalitāti.

Kvalitāte

Digitālā attēla kompresijas pakāpe. Augstākas kvalitātes attēliem ir zemāka kompresijas pakāpe, kas parasti nozīmē lielāku faila izmēru.

Izšķirtspēja

Pikseļu skaits digitālajā attēlā. Attēli ar augstu izšķirtspēju parasti satur vairāk pikseļu un parasti ir detalizētāki, nekā attēli ar zemu izšķirtspēju.

Aizvara ātrums

Aizvara ātrums attiecas uz laika periodu, kas paiet no aizvara atvēršanas līdz tā aizvēršanai, un ir svarīgs faktors, kas ietekmē attēla gaišumu, jo tas kontrolē, cik daudz gaismas izies cauri diafragmas atvērumam pirms attēla sensora sasniegšanas. Ātrs aizvara ātrums pieļauj mazāku izgaismojuma ilgumu, fotoattēls kļūst tumšāks un kustīgu objektu aprises ir skaidrākas.

Vinjetēšana

Attēla spilgtuma vai piesātinājuma samazināšanas tā perifērijā (pie ārējām malām) salīdzinājumā ar attēla centru. Izmantojot vinjetēšanu, var pievērst uzmanību objektiem, kas atrodas attēla centrā.

Baltā balanss (krāsu balanss)

Krāsu (parasti primāro krāsu - sarkanās, zaļās un zilās) intensitātes pielāgošana attēlā. Baltās krāsas vai krāsu balansa pielāgošanas mērķis ir pareizi attēlot krāsas attēlā.
