Uma ezihlokweni ezimbili zokuqala zalolu chungechunge sikhulume ngokuthi singazithuthukisa kanjani izithombe zethu futhi sikwazi ukuthatha izithombe njengochwepheshe onolwazi mayelana nesivinini sokuvala nokuzwela kwe-ISO, manje sizokhuluma ngokuvula, into esizoba nayo. ukwazi ngokuphelele ukwazi ukuthi izithinta kanjani izithombe zethu nokuthi zisetshenziswa kanjani.
Ithwebula izithombe ngezilungiselelo mathupha
Into yokuqala okufanele uyazi ukuze uqale ukusebenza ngembobo ye-diaphragm ukuthi kuwukulungiswa esingakwazi ukufinyelela kukho kuwo wonke amafoni omakhalekhukhwini. Futhi kuphela kwezinye izimo sizokwazi ukulungisa i-diaphragm aperture uma sinikezwe ithuba lokufinyelela ukulungiswa okwenziwa ngesandla. Kwamanye amaselula singase sibe nokufinyelela ekwenzeni lezi zinguquko, kodwa kuphela ngohlelo lokusebenza lwekhamera oluhlukile kweyokuqala. Noma iyiphi indlela, kufanele wazi ukuthi lesi silungiselelo singase singatholakali kuselula yakho.
Apertura
Imbobo igama leyodwa yezakhi ezintathu eziyinhloko esingaphatha ngazo ukuchayeka ekukhanyeni kusukela kunzwa yekhamera yethu. Sesivele sishilo ukuthi ukukhanya kuyisihluthulelo sanoma yisiphi isithombe, ngakho-ke lena enye into okufanele icatshangelwe, phakathi kwalezo zintathu, lapho uthwebula isithombe. Kulokhu, imbobo, njengoba negama layo libonisa, ibalulekile ngoba inquma ukuthi kungakanani ukukhanya okufinyelela inzwa. Imbobo enkulu isho ukukhanya okwengeziwe okufinyelela inzwa, kuyilapho indawo engaphansi ikhombisa ukukhanya okuncane okufinyelela inzwa.
Ungasibona kanjani isimbobo kukhamera yethu?
Manje, uma ungahlobene nale migomo, usazoba ngaphansi kakhulu ngezinkomba ezisetshenziselwa ukuvulwa. Ngokucacile, uzobona indawo yokungena evezwe njengokuthi f / 1.8, f / 2,2, f / 8… Lokhu kungase kungaziwa kuwe, kodwa le yindlela i-diaphragm aperture yekhamera ngayinye evezwa ngayo. Kuze kube manje kuhle kakhulu, inkinga ukuthi lezi zibalo azikho enembile ekuqaleni. Umuntu angase acabange ukuthi i-f / 8 iyindawo ephakeme kune-f / 1.8, kodwa okuphambene kuyiqiniso. Khumbula ukuthi i-f / 1 ithathwa njengembobo ephelele, ngakho-ke inombolo enkulu, imbobo ye-diaphragm iyancipha. Lokho kusho ukuthi nge-f/1 inzwa izobe ithwebula konke ukukhanya. Omakhalekhukhwini abanayo i-f/1. Eqinisweni, akuvamile ngisho nakumakhamera asezingeni eliphezulu anamalensi avamile. Kodwa-ke, singabona i-f / 2.8, noma i-f / 2.2 ku-smartphone. Lokhu kuzoba izimbobo eziphezulu, lezo ezizothwebula ukukhanya okuningi, kuyilapho i-f / 8 izoba indawo ephansi, futhi izothwebula ukukhanya okuncane.
Indlela yokukhetha ukuvulwa?
Ukuze ukhethe indawo efanelekile yokuvula ikhamera yakho, udinga ukugcina izinto ezimbalwa engqondweni. Into esemqoka ukwazi ukuthi imbobo ithinta kanjani izithombe ozithwebulayo. Sesishilo ukuthi imbobo enkulu yenza ikhamera ithwebule ukukhanya okwengeziwe. Futhi kunjalo. Nokho, imbobo enkulu ibuye inciphise ukujula kwensimu. Lokhu kusenza sikhethe iphoyinti lokugxila, futhi izici ezikude kakhulu nazo zibonakala zingagxilile kakhulu. Uma sizothwebula i-landscape, sifuna ukuthi yonke into ibonakale igxilile. Ngakho-ke, sidinga imbobo encane ye-diaphragm, njenge-f / 8, isibonelo. Kodwa-ke, uma sizothwebula umuntu, isithombe, esikufunayo ukuthi isizinda sibonakale singagxilile ukuze isihloko esikhulu kube umlingiswa oyinhloko. Kulokhu kuzodingeka sikhethe imbobo enkulu, njengokuthi f / 2.2.
Hlanganisa lokhu nezinye izakhi
Kodwa-ke, ukhiye ukukhetha indawo yokuvula ngokusekelwe kwezinye izinto ezimbili, ukuzwela kwe-ISO nesivinini se-shutter. Uma sidinga isivinini esikhulu se-shutter ukuze sithwebule ukunyakaza, khona-ke kuyoba i-diaphragm aperture esizoyidela ukuze sifinyelele izinga lokukhanya esilifunayo.
