Funda ukuthi uzosebenzisa nini amamodeli amamitha ahlukene
Ama-metering modes kumakhamera we-DSLR aklanyelwe ukunikeza abathwebuli bezithombe ukuthi balawule ngaphezulu kokufundwa kwemitha yokuchayeka. Ukuze usebenzise i-DSLR ngokusemandleni akhe okugcwele, kubalulekile ukuqonda ukuthi ngayinye yalezi zindlela ilinganisa kanjani ukukhanya endaweni yesehlakalo.
Ukuvezwa ngokuzenzekelayo kuyisici kuzo zonke i-DSLRs, kodwa ungakhetha futhi kumamodeli ahlukene ahlukene ukuze uhlole kahle ukukhanya kwakho. Kuye umakhi wekhamera nemodeli, kuzoba namamodeli amathathu noma amane okukhetha ukukhetha kuwo futhi ngamunye achazwe ngezansi.
Ukulinganisa noma iMetrix Metering
Imitha yokuhlola (noma i-matrix) imodi eyinkimbinkimbi kunazo zonke futhi inikeza ukuchayeka okungcono kakhulu kwezigcawu eziningi.
Ngokuyinhloko, ikhamera ihlukanisa indawo ibe yi-matrix yemingcele ye-metering futhi ithatha ukufundwa komuntu ngamunye kwesigaba ngasinye. Ukufundwa kwamamitha okuhlola kuyatholakala bese kuthiwa isilinganiso sisetshenziselwa yonke indawo.
Izinzuzo
- Kulula kakhulu ukuyisebenzisa.
- Kuhle amazwe, izithombe zeqembu nezinye izigcawu ezinemininingwane eminingi.
I-Cons
- Lemodi ayinhle kumabhayisikobho ngokukhanya okuqinile noma okuningi kwezithunzi njengoba izingxenye zesithombe zingase ziphele noma ngaphezulu.
- Ikhamera izomzabalaza kumitha ngenhloso encane.
Isisindo esinezikhungo noma esesisindo
Ukulinganisa okuphakathi kwesisindo (noma isilinganiso) kuyindlela ejwayelekile kunazo zonke yokulinganisa. Futhi kuyindlela yokuzenzakalelayo yamakhamera angenayo izinketho zemodi yokumisa.
Kulo modi, ukuchayeka kunesilinganiso esivela kuyo yonke indawo kodwa kubeka phambili kuqala (noma 'isisindo') endaweni yangaphakathi.
Izinzuzo
- Kuhle ukufotoza abantu noma izinto phakathi nendawo ye-landscape noma yesehlakalo njengoba kuzoba imitha kubo kunemuva.
- Kuhle kuma-portraits njengoba iveza isihloko hhayi isizinda.
I-Cons
- Akuyona into enhle uma isihloko sakho noma into engekho phakathi kohlaka.
- Akuyona into ephezulu ye-shots-head and shoulder egcwalisa ifreyimu. Kuzoba nemitha phakathi nendawo ebusweni kanye nezindawo ezingaphandle kungase kube ngaphezulu noma ngaphansi.
I-Spot noma Imitha Eyingxenye
Amanye ama-DSLRs anomabili ama-metering modes. Amanye amakhamera angase abe nomunye wawo kuphela futhi amanye amakhamera awanakho.
Lezi zindlela zokulinganisa zisetshenziselwa izinhloso eziqondile. Ama-spot metering amamitha okuphakathi kwendawo engu-5% yesithombe. Amamitha ayizilinganiso ezilinganayo zendawo engu-15% yesithombe. Kuzo zombili izimo, konke okuvezwayo kunganakiwe.
Izinzuzo
- Kuhle kakhulu ngoba i- macro futhi isebenza ngokuphila ngoba ivumela ukulinganisa okunembile ezintweni ezincane.
- Kuhle izithombe ezishintsha ngokuqinile ngoba kusiza ukugwema ukusikisela kwendaba.
I-Cons
- Kudinga ukusetshenziswa okuqaphele kakhulu futhi kudla isikhathi. Ukubekezela kuyadingeka ukuze uthole isibhamu esihle!
- Ukusetshenziswa okulinganiselwe, futhi kuyadingeka kuphela ekufuneni izithombe.
