1,Dab tsi yog lub lens pinhole?
Cov lens pinhole, raws li lub npe cuam tshuam, yog lub lens me me, nws shooting aperture tsuas yog qhov loj me me, nws yog lub lens siv los ntawm ultra-micro cov koob yees duab. Cov ntsiab lus pinhole siv lub hauv paus ntsiab lus ntawm lub qhov me me ua kom tau cov duab thiab muaj qee cov xeeb ntxwv tshwj xeeb thiab kev siv.
2,Cov yam ntxwv ntawm pinhole lens yog dab tsi?
Raws li lub koob yees duab tshwj xeeb ntaus ntawv, tus pinhole lens muaj qee yam tshwj xeeb:
(1)Zais cov tsos
Lub pores ntawm lub lens pinhole yog tsawg heev thiab zoo sib xws rau qhov loj me ntawm tus pinhole. Vim yog cov kab me me uas hla, qhov loj me ntawm tag nrho cov koob yees duab pinhole yog cov compact tsis tshua muaj zog, feem ntau tsuas yog npib nyiaj loj. Qhov qauv tsim me me no ua rau lub koob yees duab pinhole hos yooj yim nyob rau hauv ntau qhov chaw, thiab nws yog qhov nyuaj rau kev paub txog nws.
(2)Loj kawgslub tsev teev ntujimage
Vim yog cov qauv tshwj xeeb ntawm cov roj pinhole, nws qhov tob ntawm daim teb yog sib sib zog nqus thiab tuaj yeem tua cov duab loj -depth. Qhov no txhais tau tias cov khoom pem hauv ntej lub koob yees duab tuaj yeem pom meej meej rau ntawm qhov kev xav txog qhov chaw nyob deb. Raws li cov yeeb yaj kiab no, cov lens pephole ua tau zoo thaum kev tsim ua hauj lwm thiab architecture yuav tsum muaj kev pom tseeb loj -scale.
(3)Tsau Focal Ntev thiab Aperture
TusCov lens pinholeFeem ntau tsis muaj focal focal ntev thiab aperture. Thaum ntsia tau, lub kaum thiab lub teeb tau txais muaj peev xwm ntawm lub lens yog tsau. Txawm hais tias qhov no txwv rau qhov yooj ntawm kev sib tua rau qee yam, nws tseem ua rau lub lens pinhole yooj yim dua thiab siv tau yooj yim.

(4)Txwv kev ua tau zoo nyob rau hauv ib puag ncig qis
Txij li lub lens pephole muaj ib qho me me aperture thiab tsawg npaum li cas ntawm lub teeb, cov nyhuv tua nyob rau hauv ib puag ncig lub teeb tsawg yuav tsis zoo. Qhov no tuaj yeem ua teeb meem xws li qhov muag plooj thiab xim distortion, thiab ntxiv cov khoom siv teeb tsa lossis cov khoom siv txo kom zoo.
(5)Siv tesskev siv
Cov ntsiab muag pinhole feem ntau tsis muaj cov yam ntxwv zoo li cov autofocus thiab xav tau phau ntawv teeb tsa thiab kev hloov kho. Qhov no nce qhov nyuaj ntawm kev ua haujlwm rau qee yam, tab sis kuj muab kev ywj pheej ntxiv, cia cov kev pab yees duab kom haum raws li cov kev xav tau tshwj xeeb.
(6)Ntau yam ntawm cov ntawv thov
Tus zais thiab yooj yim ntawm kev siv ntawmCov Ntsej Muag PinholeUa kom lawv siv dav hauv ntau thaj teb. Txawm hais tias nws yog kev saib xyuas hauv tsev, chaw ua haujlwm lossis chaw saib xyuas pej xeem, cov ntsiab muag pinehole tuaj yeem ua lub luag haujlwm tseem ceeb. Nyob rau tib lub sijhawm, lawv tseem muaj siv dav hauv kev tshawb fawb, kev soj ntsuam cov tsheb, tus tsiaj thiab lwm thaj teb.
3,Cov kev siv ntawm cov ntsiab muag pinehole yog dab tsi?
Daim ntawv thov cov chaw ntawm pephole lenses feem ntau yog suav nrog cov hauv qab no:
(1) Kev Ruaj Ntseg
Cov ntsiab muag pinhole yog cov me thiab zais, yog li lawv tuaj yeem ntsia tau rau hauv cov khoom siv me me thiab siv raws li zais kev ntsuas kev ruaj ntseg. Vim tias lawv lub me me, lawv tuaj yeem muab zais tau yooj yim txhua qhov chaw rau covertly tua ib puag ncig.
