Oko kufuneka ukwazi malunga ne-lccorder's lens.
Ngaphandle kokujonga ukuba uluhlu oluninzi lupakisha, amathuba ukuba awuyikuqwalasela ingqalelo kwilenki yekhamera. Ngubani ojongayo ngecala leglasi xa ubona ubuso kunye neGPS yokuthetha? Ewe, kufuneka uzinakekele! I-lens ibandakanya indlela i- camcorder yakho isebenza ngayo . Kukho iintlobo ezimbini ezisisiseko ze-lccorder lens: ezo zakhiwe-kwi-camcorder kunye neelensi zokufumana izinto onokuzithenga emva kweqiniso kwaye unamathele kwi-camcorder yakho yeempembelelo ezithile. Eli nqaku lijolise kwizenzi ezakhiweyo kuphela. Unokufunda okubanzi malunga neenkcukacha zamaccorder lens apha.
Optical Zoom Lenses
I-camcorder ene-optical zoom lens inakho ukuphakamisa izinto ezikude. Iyenjenjalo ngokuhambisa iziqwenga zeglasi ngaphakathi kwe-camcorder. Ama-lens zoom optical ahlukaniswe ngokuphakanyiswa kobuninzi, ngoko ke i-zoom ye-zoom ye-10x inokuphakamisa into ephindwe kabini.
IiLens Focus Focus
I-lens egxininiswe ngokukodwa yinto engashukunyanga ukufikelela ekukhuliseni. "Ichanekile" kwindawo. Amakhamera amaninzi aneengqungquthela ezijoliswe ekujoliswe kuyo iya kunika "i-zoom zoom". Ngokungafani nomlingani walo optical, zoom zoom yedijithali ayinakudlulisa into ephakamileyo. Ilula nje indawo ukuba "ingqalelo" phantsi kwesifundo esithile. Ukuze ufunde ngokubanzi malunga nendlela yokwenza idijithali isebenza ngayo kwaye kutheni ihluke (kwaye iphantsi) ukuya kwitsaliso yokubonakala, nqakraza apha.
Ukuqonda Ubude obujoliswe kuyo
Ubude obude beli lensi bubhekisela kumgama ukusuka kwiziko lensini ukuya kwindawo ekujoliswe kuyo kwintetho yomfanekiso apho umfanekiso ujolise khona. Kutheni le nto? Eyona ndlela, ubude obuphambili yindlela elula kakhulu yokukuxelela ukuba unomtsalane kangakanani ukonakalisa ikhamera yakho yekhamera kwaye yintoni eyifumayo.
Amanqaku agxininisiweyo alinganiswa ngeimitha. Ukufumana i-camcorders nge-lens zoom zoom, uza kubona amanani amabini: owokuqala ukunika ubude obude kwindawo yokubanzi kunye neyesibini ukukunika ubude obude ekujoliswe kuyo kwi-telephoto (oko kukuthi xa "usondeza" okanye wakhulisa isihloko). Ukuba uthanda izibalo, unokwazi ukuphakanyiswa, okanye "x" yecandelo lakho lekhamera ngokuhlukanisa inombolo yesibini kwindawo ekujoliswe kuyo kuqala. Ngoko i-camcorder ene-35mm-350mm lensi yayiza kubonakalisa i-zoom ye-10x.
IWide Angle Lenses
Inombolo ekhulayo yamaccorders iqalile kuzo zonke iilensi ezibanzi . Akukho miselo okhuni kunye wokukhawuleza xa i-lc encoded-in inkccorder lens ithathwa njenge-wide angle-angle, kodwa ngokuqhelekileyo uza kubona imodeli epapashwa njengolu hlobo ukuba unobungakanani obude ngaphantsi kwe-39mm. Njengalo gama lithetha, i-lens wide angle ingabamba ngaphezulu kwesiganeko ngaphandle kokuba umqhubi kufuneka athathe isinyathelo okanye amabini abuyele ukuze angene kuyo yonke inzuzo.
Ukuqonda ukuvula
I-lens ilawula umlinganiselo wokukhanya owela kwi-sensor isebenzisa isithsaba, esibizwa ngokuba yi- iris. Cinga ngomfundi owandisa ukuvumela ukukhanya okanye ukukhawuleza ukuvumela ukukhanya okungaphantsi uze ufumane ingcamango yokuba iris isebenza njani.
Ubungakanani bokuvulwa kwe-iris bubizwa ngokuba yi-aperture. Iikhamera ezithengi ngakumbi ziya kukuvumela ukuba ulawule ubungakanani bokuvula. Oku kubalulekile ngezizathu ezibini:
1. Ubume obanzi buvumela ukukhanya ngakumbi, ukukhanyisa imeko yakho kunye nokuphucula ukusebenza kwiimifanekiso ezibukhali. Ngokwahlukileyo, ukuvula okuncinci kukuvumela ukuba kube lula ukukhanya.
2. Ukulungiswa kwe-lens aperture kukuvumela ukuba ulungelelanise ubunzulu bendawo, okanye ubuninzi bomhlaba ojoliswe kuyo. Ubume obanzi buza kwenza izinto phambi kwakho zijoliswe kakuhle kodwa imvelaphi ifumaneke. Ukukhutshwa okuncinci kuya kwenza konke kugxilwe.
Abenzi beekhamera bavame ukuvakalisa ukugqithiswa okukhulu-oko kukuthi i-iris ivule kangakanani ukuvula ukukhanya. Ububanzi, bhetele.
Ungayichazela Njani I-Camcorder yakho kunye ne-# 39; s Aperture?
Ukukhutshwa kwe-camcorder kubalwa kwi "f-stops". Njenga-zoom zoom optical, ungenza izibalo ezithile ukucacisa ukuphakama okuphezulu kwekhamera yakho. Ukwahlula nje ubude beembali ngokubanzi kwelo lensi (oku kufakwe ngokusemgangathweni kumgca we-lens barrel). Ngoko ke, ukuba unayo i-lentim 220mm ububanzi obungama-55mm, uza kuba ne-f / 4.
Inombolo engaphantsi kwenombolo ye-f-stop, i-widen the open lens. Ngoko ngokungafani ne-zoom zoom, apho ukhangele inamba ephezulu, ufuna i-camcorder nge-down-down, okanye inombolo ye-f-stop.
