Iilensi zeTelecentric, eyaziwa ngokuba ziilensi ze-tilt-shift okanye iilensi ze-soft-focus, zineempawu ezibaluleke kakhulu zokuba imo yangaphakathi yelensi inokwahluka kwiziko le-optical lekhamera.
Xa ilensi eqhelekileyo idubula into, ilensi kunye nefilimu okanye isenzi zikwindawo enye, ngelixa ilensi ekwi-telecentric inokujikeleza okanye ityekise isakhiwo selensi ukuze iziko le-optical lelensi liphambuke embindini wesenzi okanye ifilimu.
1,Iingenelo kunye nokungalungi kweelensi ze-telecentric
Inzuzo 1: Ubunzulu bolawulo lwentsimi
Iilensi zeTelecentric zinokugxila kwiindawo ezithile zomfanekiso ngokutshintsha i-engile yokuthambeka kwelensi, ngaloo ndlela zivumela abafoti ukuba benze iziphumo ezikhethekileyo zokugxila, njengesiphumo seLilliputian.
Inzuzo 2: Imbonoculawulo
Enye yezona nzuzo ziphambili zeelensi ze-telecentric kubafoti bezakhiwo kukuba zibonelela ngolawulo olukhulu kwindlela ebonwa ngayo. Iilensi eziqhelekileyo zinokubangela ukuba imigca ethe tye kwimifanekiso (njengemigangatho edibeneyo yesakhiwo) ibonakale igobile, kodwa iilensi ze-telecentric zinokutshintsha umgca obonakalayo ukuze imigca ibonakale ithe tye okanye iqhelekile.
Inzuzo 3: I-engile yokubukela yasimahla
Iilensi zeTelecentric ziyakwazi ukudala ii-engile ezahlukeneyo zembono (oko kukuthi, iimbono ezingahambelaniyo nesensor). Ngamanye amazwi, ukusebenzisa i-ilensi ye-telecentricikuvumela ukuba ubambe umbono obanzi ngaphandle kokuhambisa ikhamera, nto leyo eluncedo kakhulu kubafoti bezakhiwo kunye nezithombe zembonakalo yomhlaba.
Ilensi ye-telecentric
Ingxaki 1: Ukusebenza okuntsonkothileyo
Ukusebenzisa nokuqonda iilensi ze-telecentric kufuna izakhono ezikhethekileyo kunye nokuqonda okunzulu ngokufota, nto leyo enokuba nzima kwabanye abafoti abasaqalayo.
Ingxaki 2: Ibiza kakhulu
Iilensi ze-telecentric zibiza kakhulu kuneelensi eziqhelekileyo, nto leyo enokuba lixabiso abanye abafoti abangenakulimkela.
Ingxaki 3: Izicelo zilinganiselwe
Nangonaiilensi ze-telecentricziluncedo kakhulu kwiimeko ezithile, ezinje ngefoto yoyilo lwezakhiwo kunye nefoto yembonakalo yomhlaba, ukusetyenziswa kwazo kunokulinganiselwa kwezinye iimeko, ezinje ngefoto yemifanekiso, iifoto zesenzo, njl.
2,Umahluko phakathi kweelensi ze-telecentric kunye neelensi eziqhelekileyo
Umahluko omkhulu phakathi kweelensi ze-telecentric kunye neelensi eziqhelekileyo zikwimiba elandelayo:
Ubunzulu bolawulo lwentsimi
Kwilensi eqhelekileyo, i-focal plane isoloko ihambelana nesensor. Kwilensi ye-telecentric, ungayijika ilensi ukuze utshintshe le plane, ukuze ukwazi ukulawula ukuba yeyiphi inxalenye yomfanekiso ebukhali kwaye yeyiphi inxalenye yomfanekiso engacacanga, nto leyo ekunika ulawulo oluphezulu kubunzulu bentsimi.
Usetyenziso lokufota iilensi zeTelecentric
Ukuhamba kwelensi
Kwilensi eqhelekileyo, ilensi kunye nesenzi somfanekiso (njengefilimu yekhamera okanye isenzi sedijithali) zihlala zihambelana. Kwilensi ye-telecentric, iindawo zelensi zinokuhamba ngokuzimeleyo ngaphandle kwekhamera, okuvumela umgca wombono welensi ukuba uphambuke kwiplani yesenzi.
Le ndalo ishukumayo yenzaiilensi ze-telecentricilungele ukufota izakhiwo kunye neendawo ezikuyo, njengoko itshintsha indlela ebonakala ngayo kwaye yenza imigca ibonakale ithe tye.
Ixabiso
Iilensi zeTelecentric zihlala zibiza kakhulu kuneelensi eziqhelekileyo ngenxa yobuchule bokwakhiwa kunye nokusetyenziswa kwazo.
Aukuqina
Iilensi ze-telecentric ngokubanzi kufuneka zixhotyiswe nge-aperture enkulu, eluncedo ekufotweni kwiindawo ezinokukhanya okuphantsi.
Kufuneka kuqatshelwe ukuba nangonaiilensi ze-telecentricZingadala iziphumo ezibonakalayo ezizodwa, zinzima ukuzisebenzisa kuneelensi eziqhelekileyo kwaye zifuna izakhono eziphezulu kumsebenzisi.
Iingcinga Zokugqibela：
Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
