Isimiso ezisebenza ka SLR amakhamera

Omunye amaphutha ezivamile imfundamakhwela bezithombe abakulindele iphakeme kakhulu phezu impumelelo ubuchwepheshe besimanje. Amaforamu anikezelwe izithombe digital, sikhungathekile ihlaya ku zifiki. Ngokwesibonelo, umuntu elomela kakhulu ukufunda ukuthatha izithombe, kodwa akafuni ukuqonda izithombe. Unethemba lokuthi umkhiqizo wakhe omusha SLR ikhamera ukwenza konke ngaye, kodwa izithombe ezinhle izotholwa emshinini, kodwa izimangaliso abekho. Ngemva kwalokho, i-photographer sifisa iyeke ukuphishekela le umdlalo, ukuchitha kuso isizumbulu semali (ukuthenga SLR) noma iqala ukufunda mayelana izithombe ezifanele. Isihloko sethu kuyoba usizo Wabasaqalayo isigaba sesibili, okuzokwenza kube mnandi ukufunda isimiso reflex umehluko yayo kusukela evamile ikhamera yedijithali.

Okokuqala, kulula ukuba esikhundleni, kuba ukufana ukubukeka e SLR amakhamera kanye amakhamera digital, ngaphezu Ubukhulu. Sony SLR amakhamera kuqhathaniswa ezivamile khamera babe Ubukhulu esikhulu. Kodwa DSLR isimiso ehluke ngokuphelele. Okokuqala, SLR ikhamera ivumela photographer ukubuka isithombe ngendlela efanayo kubukeka. A digital ikhamera isithombe ukuhlelwa ngaphambi kokuba afinyelele screen, lokhu kungenye umehluko kusuka DSLRs yabo. Sinenkosi phakathi imifanekiso nezithombe azikho izintambo ezengeziwe futhi izingxenye electronic, okungase, nganoma iyiphi indlela phendulela isithombe.

SLR amakhamera futhi ngokuthi esibukweni isithombe ewela kusitholi sokubonwayo lidlula kuphela ngokusebenzisa eziningana amalensi ujikelezisa esibukweni efakwe ngaphakathi ikhamera. Ngenxa yalokhu-ke akuyona uhlanekezelwe. Kodwa le ncazelo akusho alibonise ngokugcwele isimiso wokusebenza SLR amakhamera. Ukuze uthole incazelo eningiliziwe - ukulandelela indlela umsebe wokukhanya, ukudala ngomfanekiso wethu. Into yokuqala isithombe ewela lens oboktiva khona futhi refracted. Physics uchaza lokhu ngenxa yokuthi une ikhono ukunciphisa noma ukwandisa isithombe ngendlela othanda ngayo. Ngemva ukudlula ukukhanya lens, yona ithunyelwa esibukweni rotary ikhamera, ke uthola phezu yezokubona ngqo pentaprism kusitholi sokubonwayo. Singasho e kusitholi sokubonwayo ungabona ibonisa ukuthi kwenzekani phambi oboktivom. Ezinye amakhamera Nikon SLR ungaba ezimbili oboktiva - omunye ukuqopha, elinye libe sokuhlola kuqala.

Kwenzekani okwamanje bethwebula?

Emva kokuthatha isikhundla lesifanele lens futhi endaweni efanele, umthwebuli ngazo inkinobho yokucina. Ngesikhathi esifanayo, ibenze rocker swivel esibukweni phezulu, ivimbela kusitholi sokubonwayo. Ngenxa yalokho, okwamanje ngokudubula ke abakwazi ukubona noma yini. Khona-ke umsebe wokukhanya uhamba indlela efanayo uma ubheka isithombe ngokusebenzisa kusitholi sokubonwayo kodwa kunalokho sibonakala ngokwanda kusitholi sokubonwayo, kubonakala kungxenye photosensitive. Ngo SLR amakhamera kuba matrix (i inzwa isithombe). Ngo isidlo insipho wefilimu empeleni kakhulu ifilimu. Isikhathi lapho yesivalo ivulekile, shutter libizwa ukungaphumeleli.

Kulesi sihloko, sabuka isikimu ejwayelekile yomsebenzi reflex ikhamera yedijithali nomunye lens.
