1,Indorerwamo y'urumuri rw'inyuma ni iki?
Ijisho ry'urumuri, nk'uko izina ribisobanura, ni lenzi nto cyane, umwobo wayo wo kurasa ungana n'umwobo w'icyuma, ni lenzi ikoreshwa na kamera zikora mikoro cyane. Lenzi zikoresha ihame ryo gufata amashusho y'umwobo muto kugira ngo zibone amashusho kandi zigire imiterere n'imikorere byihariye.
2,Ni ibihe biranga lenzi y'umugozi?
Nk'igice cyihariye cy'igikoresho cya kamera, lensi y'umugozi ifite imiterere idasanzwe:
(1)Isura ihishe
Utubobo tw’indorerwamo y’urumuri ni duto cyane kandi ungana n’ingano y’urumuri. Kubera umurambararo muto w’urumuri, ingano ya kamera yose y’urumuri ni nto cyane, akenshi ni igiceri gusa. Iyi miterere mito ituma kamera y’urumuri rwinshi yihisha byoroshye ahantu hatandukanye, kandi biragoye kubimenya.
(2)Byiza cyanescenarioiumupfumu
Bitewe n'imiterere yihariye ya lensi y'umwobo w'inyuma, uburebure bwayo ni burebure cyane kandi ishobora gufata amashusho manini. Ibi bivuze ko ibintu biri imbere ya kamera bishobora kugaragara neza ku buso bw'ifoto hatitawe ku ntera. Hashingiwe kuri iyi miterere, lensi y'umwobo w'inyuma yitwaye neza iyo amashusho y'ahantu n'inyubako bisaba ubushishozi bunini.
(3)Uburebure bw'ibanze n'ahantu hadahinduka
Itsindaindorerwamo y'umwobo w'ijishoUbusanzwe ntabwo ifite uburebure bw'inyuma n'ubuso bushobora guhindurwa. Iyo imaze gushyirwaho, inguni n'ubushobozi bwo kwakira urumuri bya lens birahinduka. Nubwo ibi bigarukira ku bworoshye bwo kurasa ku rugero runaka, bituma lens yo mu mwobo wo hejuru yoroha kandi yoroshye kuyikoresha.
Ikirahuri cy'umwobo w'inyuma
(4)Imikorere mike mu duce dufite urumuri ruto
Kubera ko lenzi y'urumuri ifite umwobo muto n'urumuri ruto, ingaruka zo kurasa ahantu hadateye urumuri rwinshi zishobora kuba zitameze neza. Ibi bishobora guteza ibibazo nko kubona amashusho adasobanutse neza no guhindura amabara, kandi hakenewe andi masoko y'urumuri cyangwa ibikoresho by'inyongera kugira ngo kunoze ingaruka zo kurasa.
(5)Inyuguti ya Manualsgusinya
Ubusanzwe, lenzi zo mu bwoko bwa Pinhole ntabwo zigira imiterere ihanitse nka autofocus kandi zisaba igenamiterere n'impinduka mu buryo bw'intoki. Ibi byongera imiterere y'imikorere ku rugero runaka, ariko kandi binatanga ubwisanzure bwinshi, bigatuma abafotora bashobora guhindura uko babyifuza bitewe n'ibyo bakeneye.
(6)Porogaramu zitandukanye
Uburyo bwo guhisha no koroshya ikoreshwa ryaindorerwamo z'umwoboBikoreshwe cyane mu nzego nyinshi. Byaba ari ukugenzura umutekano wo mu rugo, kugenzura ibiro cyangwa kugenzura ahantu hahurira abantu benshi, lenzi zo mu jisho zishobora kugira uruhare runini. Muri icyo gihe, zikoreshwa cyane mu bushakashatsi bwa siyansi, kugenzura imodoka, kugenzura inyamaswa n'izindi nzego.
3,Ni izihe ngamba zo gukoresha indorerwamo z'ijisho (pinhole lenses)?
Ahantu hakoreshwa indorerwamo z'ijisho ry ...
(1) Gukurikirana umutekano
Indorerwamo z'urumuri ni nto kandi zihishe, bityo zishobora gushyirwa mu bikoresho bito cyane kandi zigakoreshwa mu kugenzura umutekano mu ibanga. Kubera ko ari ntoya, zishobora guhishwa ahantu hose mu buryo bworoshye kugira ngo zigaragare mu ibanga.
Ijisho ry'umugozi rikoreshwa mu kugenzura umutekano
(2) Gukurikirana ibinyabiziga
Indorerwamo z'urumuri zifite uruhare runini mu micungire y'umuhanda mu mijyi. Zikoreshwa mu gufotora amakosa yo mu muhanda, gufata amafoto y'impanuka zo mu muhanda, n'ibindi, bigafasha mu kunoza umutekano w'umuhanda no kunoza imicungire yawo.
(3) Urwego rw'ubuhanzi
Indorerwamo za Pinhole zikoreshwa mu buhanzi kugira ngo zikore amashusho yihariye. Kubera ko indorerwamo za Pinhole zifite uburebure butagira ingano, zishobora gutuma ishusho y'imbere n'iy'inyuma igaragara neza. Abahanzi benshi n'abafotozi bakoresha ubu buryo kugira ngo bakore ishusho y'inzozi kandi igezweho.
(4)Urwego rw'ubushakashatsi bwa siyansi
Bitewe n'imiterere yaindorerwamo z'umwobo, kandi zikoreshwa cyane mu rwego rw'ubushakashatsi bwa siyansi. Urugero, mu gusuzuma ikirere, lenzi z'imirongo ishobora gukoreshwa mu kureba izuba cyangwa izindi nyenyeri zo mu kirere. Muri icyo gihe, lenzi z'imirongo y ...
(5)Urwego rw'ubuvuzi
Mu gupima amashusho hakoreshejwe radiyo n’imiti ya kirimbuzi, indorerwamo zifite utwenge zigira uruhare runini mu buhanga bwo gupima amashusho butari ubwandu nka PET (positron emission tomography) na SPECT (single photon emission computed tomography).
Ijisho ry'inyuma ry'umugozi rikoreshwa mu gusuzuma kwa muganga
(6)Urugaga rw'uburezi
Indorerwamo z'urumuri (pinhole lenses) nazo zikoreshwa cyane mu burezi, cyane cyane mu kwigisha ibijyanye n'amashusho no gufotora, kugira ngo zifashe abanyeshuri gusobanukirwa uburyo urumuri rukwirakwira binyuze muri lens n'uburyo amashusho akorwa.
(7)Umuntu ku giti cyepgushushanya
Uburyo isura y'ifoto y'umuntu ku giti cye ihisha kandi butuma igira akamaro mu bijyanye no gufotora abantu ku giti cyabo. Abantu bashobora guhisha ifoto y'umuntu ku giti cye nk'ibintu bya buri munsi, nk'udusanduku tw'impapuro, icyuma cyo kwiyuhagiriramo, amatara mato yo ku meza, n'ibindi, kugira ngo ifotorwe mu buryo bwihishe.
Bikwiye kumenyekana ko bitewe n’imiterere yayo ihishe, indorerwamo z’umwobo wo mu jisho nazo zoroshye gukoreshwa n’abaca amategeko mu bikorwa bitemewe n’amategeko, nko gushakisha, gufotora mu ibanga, n’ibindi, bibangamira cyane ubuzima bwite bw’abaturage n’icyubahiro cyabo.
Bityo rero, iyo ukoreshejeindorerwamo z'umwobo, amategeko, amabwiriza n'amahame mbwirizamuco bireba bigomba kubahirizwa kugira ngo bikoreshwe mu buryo bwemewe n'amategeko kandi byubahirize amabwiriza.
Ibitekerezo bya nyuma:
Niba ushishikajwe no kugura ubwoko butandukanye bw'amalenzi yo kugenzura, gupima, indege zitagira abapilote, inzu igezweho, cyangwa ikindi kintu icyo ari cyo cyose, dufite ibyo ukeneye. Twandikire uyu munsi kugira ngo umenye byinshi ku malenzi yacu n'ibindi bikoresho.
