ISO uvakalelo. ulwazi olusisiseko

Ingcinga yokuba uvakalelo ISO kukuthi, yenye yezona core. Kuyimfuneko ukuba nkqu umfoti mfundi, ngaphandle, Kakade ke, akukho iindleko kunye nobungcali.

Lobuzaza ISO - ngumlinganiselo we kwimbono ikhamera matrix elizifumeneyo ukukhanya. kwinqanaba ISO High kunika ithuba lokuba athathe iifoto environments zokukhanya. Nje kwiminyaka embalwa edlulileyo, i-ISO kwakungafani ikhamera, kwaye le filim ngokwayo, yaye kwakufuneka ukutshintsha umboniso, ukukhetha eyona ifanelekileyo umfanekiso izakhelo ezininzi kunye namanqanaba ahlukeneyo nokufota ukukhanya. Namhlanje, njengoko ikhamera professional (SLR kunye mirrorless) kunye engahlawulwayo (digital resources) kuba umsebenzi wolawulo ISO uvakalelo ncwadana kunye automatic, nto leyo yenza kube lula ukwenza ipali ukungqinelana ezahlukeneyo, ukurekhoda phezu kwikhadi lememori efanayo.

Xa ukukhanyisa zaneleyo ukukhutshwa eyiyo yokungakhuseleki akusoloko kusenzeka ukuba ukusebenzisa ifleshi lwangaphandle (kwaye ngaphakathi). Kwiimeko ezinjalo, kufuneka uthsintshe uvakalelo ISO ukuya phezulu okanye susa enye on yayo oluzenzekelayo.

Ukongeza, i-hlengiso yenqanaba uvakalelo kunokukunceda ukuba awukwazi ukwandisa isantya kwaye ngaphandle kokusebenzisa i enemilenze emithathu. Kulo mzekelo, ukusetyenziswa amaxabiso aphezulu ISO kuzakwandisa isantya shutter.

Noko ke, bekuya kuba lula kakhulu ukuba ukusebenzisa njalo amaxabiso aphezulu ISO zange ube nefuthe icala. Ngapha koko, ngokuba iikhamera matrix zakhiwe ngendlela yokuba ukwanda ISO ubuntununtunu ukunyuka. Kwaye kule meko ke fixed ukukhanya kuphela, kodwa kananjalo-ebizwa ngokuba ingxolo.

Le ichaza uluhlu lwamaxabiso elilelona isisombululo ISO matrix camera. I aphezulu oko, inowuthi izinga lengxolo nokuba izicwangciso aphezulu ISO. Le khamera (kwaye "SLR" yaye "isepha") esi matrix ayikho ngaphantsi kwe 2.3 "bunikwa kwi engundoqo.

Oku kufuneka iqondwe ukuthintela engachananga eliqhelekileyo kwenzeka ngezinye wabaqalayo: Musani ukuzicingela ukuba nefilimu ngakumbi kwi camera, ngcono ke. Nje inani eliphezulu noko nefilimu abanye abenzi bazama ukubeka iikhamera kungena isizalo, unako kakhulu ukunciphisa umgangatho imifanekiso ngokoMthetho isahlakalo ingxolo ngokugqithiseleyo. Ngoko ke musa sikholelwe izibhengezo zentengiso.

Ngoko ke, ukuze batole amaxabiso ISO ubuninzi kunokuba kuphela xa kuvunyiwe:

• Ukuba kukho ukukhetha phakathi nokuba ukwenza umfanekiso ingxolo okanye ukudubula.
• Ukuba iimeko ukudubula musa ukuvumela ukusetyenziswa flash.
• Ukuba uceba uprinte iifoto format encinane, apho ingxolo siphantse sikakrebe.
• Ukuba kunokwenzeka ukunciphisa izinga lengxolo yi unyango.

A nokudubula kwindawo evulekileyo kwi ezaneleyo sokukhanya ukhetho elilelona - ISO ubuntununtunu lusekiwe kwi ixabiso ubuncinane. Yiloo nto uya kufumana imifanekiso kakuhle.
