Pa chizindikiro ichi, monga ISO, kamodzi "anathamangira" mu kamera menyu wanu. Komabe, sikuti aliyense amadziwa za izo. Tiyeni tiwone chimene ISO mu kamera.
Mu njira imeneyi amabisa kamera tilinazo. Tilinazo ndi apamwamba, ndi apamwamba mtengo wa anati chizindikiro ndi mtengo wapatali wa chithunzi pamaoneka phokoso kwambiri. Ndicho chifukwa akatswiri amavomereza ntchito malo otsika ISO, kupeza zithunzi apamwamba popanda phokoso. Pogwira kuwombera mu kuwala wochepa popanda miyendo itatu ndi kuwonjezera phindu chizindikiro ichi. Ngati uyu adzakhala kabowo kwathunthu lotseguka, mukhoza kuwonjezera shutter liwiro, kuti chithunzi sakhala amaona. Ngati tiyenda pachimene ndi ISO mu kamera, tisaiwale kuti pamene kuwombera usiku akhale ntchito miyendo itatu, ndipo anapereka mtengo wa chizindikiro ichi pansipa. Pamene kung'anima ntchito mu mtengo wake mkulu Sikuti.
Tikumbukenso kuti chiwerengero cha phokoso pa chithunzi pa mtengo wapatali ISO zimatengera mwachindunji pa kukula kwa masanjidwewo ntchito kamera. Ngati ndi makamera yaying'ono, izo ziyenera ISO 800 sitiyenera kuyembekezera zotsatira zabwino. Osauka kuunikira adzakhala chifukwa chithunzi adzakhala kwathunthu topaka. Pankhaniyi, m'chipinda asungidwe pa miyendo itatu mwa ntchito mtengo wotsika. Pamene inu ntchito ndi katundu katswiri kapena theka-akatswiri angathe kuikidwa kufunika kwake kanayi apamwamba, ndi fano khalidwe imangokhala zidzasintha.
Kupatula chakuti ISO mu kamera, M'pofunikanso kukumbukira kuti n'zotheka kukhala Auto ISO. Mwina kudziŵika kuti Mbali imeneyi ndi capricious ndithu. Ngati inu ntchito sopo, muyenera anapereka ISO 100 osati kundivutitsa. Pamene ntchito SLR kamera akhoza kuchepetsa Auto ISO malire ena. Mwachitsanzo, anapereka mtengo wapatali kwambiri pa chizindikiro cha 800, ndiye kamera sadzatha iyo, ngakhale kuli koyenera.
Ngati ife kulankhula zimene ISO, tiyenera kukumbukira kuti kufunika zingakhale zosiyanasiyana ndithu. Mu makamera masiku ano apeza angapo mfundo mkati 50-204800. Kwakung'ono gulu zambiri umatha pa kuzungulira 1600, ndi makamera ndi patsogolo kwambiri akafika 3200. mfundo The apamwamba sizimatanthauza mu moyo weniweniwo, iwo akhoza kukhala zothandiza kuwombera yotsatana, anapanga pa makamera akatswiri.
Ngati mumamwa kamera yadigito, ndiye pali ena malo okwezeka ISO kolowera zingakhale zothandiza. Chinthu choyamba kunena za zochitika kanthu, m'madera kung'anima sangathe ntchito chifukwa ina, koma Kuphunzira alibe khalidwe. Pochititsa kuwombera usiku mzinda bwino ntchito miyendo itatu, atakhala nthawi zonse-mtengo wapatali wa tilinazo, koma popanda kugwiritsa ntchito kung'anima.
Tsopano inu mukudziwa zomwe ISO kamera.
