Tsvaga Camera Viewfinder Kuti Uwane Zvaunoda
Itaona yekhamera ndiyo inokubvumira kuona mufananidzo waunotora. Kune mhando dzakasiyana dzemafungidziro anoshandiswa pamakamera akasiyana-siyana ema digital aripo nhasi. Kana uchitenga kamera itsva , zvinokosha kuziva kuti ndechipi chekuona chinyorwa chaunoda.
Chii chinonzi Viewfinder?
Mucherechedzo wacho uri kumusoro kwemashure makamera emakambani, uye iwe unotarisa kuburikidza nawo kuti unyora nzvimbo.
Ramba uchifunga kuti havasi ose makamera e digital ane viewfinder. Dzimwe pfungwa uye kupfura, makhamera ekugadzirisa haafaniri kusanganisira maonero, zvichireva kuti unofanira kushandisa LCD skrini kuti uise mufananidzo.
Nekamera inosanganisira viewfinder, iwe nguva dzose unenge uine sarudzo yekushandisa muoneki kana LCD kuti uise mapikicha ako. Pane dzimwe makamera eDLRLR iyi haisi yekusarudza.
Kushandisa viewfinder panzvimbo yeLCD skrini rine zvishoma zvingabatsire:
- Inotarisa inobudisa simba shoma kubva kubheteri.
- Mucherechedzo unobvumira kuti uve nani pane zviri nani nokuti iwe unobata kamera pedyo nemuviri wako.
- Mucherechedzi anoita kuti unzwe semufananidzo chaiye!
Kana ukangoshandiswa kushandisa kamera yekuona yako kamera iwe unogona kazhinji kuchinja kamera yekutonga zvisizvo pasina kutarisa kure.
Kune zvitatu zvakasiyana siyana zvekhamera kuona.
Optical Viewfinder (pane Digital Compact Camera)
Iyi ndiyo nzira isina nyore iyo iyo optical viewfinder inowedzera panguva imwecheteyo seyiyo huru. Nzira yayo yakajeka inotarisana neyendaneti asi haisi kukuratidza chaizvoizvo chiri mu chitubu chemufananidzo.
Maonero ekugadzirisa, maonero uye kupfura makamera anowanzove ari maduku, uye anowanzotarisa anenge 90% yezvaanenge achitora. Izvi zvinozivikanwa se "parallax error," uye zvinonyatsooneka apo nyaya dziri pedyo nekamera.
Mune mamiriro ezvinhu akawanda, zvakanyatsoshanda kushandisa LCD skrini.
Optical Viewfinder (pane DSLR kamera)
DSLRs vanoshandisa girazi nejeri uye izvo zvinoreva kuti hapana parallax error. Iko optical viewfinder (OVF) inoratidza izvo zvicharatidzwa mu sensor. Izvi zvinonzi "kuburikidza ne" lens "teknolojia, kana TTL.
Mucherechedzi wacho anoratidzawo bhari yemamiriro nechomukati pasi, izvo zvinoratidza kufungidzira uye ruzivo rwekugadzirisa ruzivo. Munharaunda zhinji dzeDVDLR makamera iwe uchaona zvakare uye unokwanisa kusarudza kubva kumativi akasiyana-siyana autofocus, anoonekwa sediki madhorobha mabhokisi neakasanangurwa akaratidzwa.
Electronic Viewfinder
Iko-electronic viewfinder, kazhinji inopfupiswa kuEVF, inoshandiswawo TTL teknolojia.
Inoshanda nenzira yakafanana nekwenyasi yeLCD pane compact kamera, uye inoratidza mufananidzo uri kuenzanirwa pane sensor ne lens. Izvi zvinoratidzirwa munguva chaiyo kunyange zvazvo kune zvimwe zvinogona kunonoka.
Nenyanzvi, EVF iLCD duku, asi inopindirana nemigumisiro yevakatarisa vakawanikwa paDLRLRs. IEVF hainawo kutambura nemafungiro eparallax.
Vamwe veEVF vanoona zvichakupawo ruzivo mumabasa akasiyana-siyana kana kuregererwa kwekamera. Iwe unogona kuona nzvimbo dzakasimbiswa dzinogadzirisa pfungwa iyo kamera inotarisa nayo kana inogona kuenzanisa kubuda kwechifungu iyo ichabatwa. IEVF inogonawo kukurudzira kubwinya kamwe chete mumasikati machena uye kuratidza kuti pahwindo.
