Indorerwamo za Varifocalni ubwoko bwa lenzi bukoreshwa cyane mu gufotora. Zishobora guhindura inguni n'imiterere y'amafoto binyuze mu guhindura uburebure bw'icyerekezo, bigatuma lenzi imwe ifata amashusho atandukanye nta mpamvu yo guhindura lenzi kenshi, bityo zikagera kuri "lenzi imwe kuri buri kimwe".
1.Ibyiza by'ingenzi byaingirabuzimafatizoamajipo
(1)Uburyo bworoshye bwo gushushanya
Ugereranyije n'ama-lenses ahamye, ama-lenses ya varifocal ashobora gutwikira uburebure bwinshi bw'ama-lenses muri lense imwe, agafata ibitekerezo bitandukanye. Atuma umuntu ashobora guhindura vuba kuva kuri 'wide-angle' akajya kuri 'telephoto' nta guhindura ama-lenses, bigatuma aba meza cyane mu bihe bisaba guhindura imiterere yihuse, nko gufotora ingendo no mu birori.
Urugero, kuva ku miterere minini kugeza ku miterere y'ibintu biri kure, gukoresha lensi ya zoom bikubiyemo kuzunguruka impeta ya zoom, bikakurinda gutakaza umwanya uhinduranya lensi.
(2)Uburyo bwo gutwara no gukoresha neza
Ilensi imwe ifite imiterere ya varifocal ishobora gutwikira imiterere yagutse kuva kuri telephoto iciriritse, igahura n'ibikenewe bitandukanye byo gufata amashusho. Ishobora gusimbura lensi nyinshi zihamye, ikagabanya uburemere bwo gutwara n'igihe umara uhinduranya amalensi, bigatuma iba nziza cyane mu bihe ukeneye kugenda mu buryo bworoheje, nko gufotora mu muhanda no gutembera mu misozi.
Urugero, iyo ufotora mu muhanda, lensi ya telephoto ishobora gukoreshwa mu gufata vuba ahantu inyoni iguruka cyangwa ikintu kiri kure, mu gihe lensi ifite inguni nini ishobora gukoreshwa mu gufata amashusho y’abantu hafi.
Indorerwamo za Varifocal zitanga imiterere yoroshye kandi zifite akamaro kanini
(3)Ubushobozi bwo kurasa bukoresha imbaraga
Mu gufata amashusho mu buryo buhindagurika nka videwo, lense zoom zemerera guhindura impeta ya zoom hakoreshejwe intoki cyangwa moteri kugira ngo zoom yinjire kandi isohoke, ziyobore ijisho ry'ureba, zigakora zoom nziza kugira ngo zikore neza mu migendekere ya kamera, ndetse zigatanga ingaruka zidasanzwe. Urugero, gukoresha lense zoom kugira ngo usunikira impeta ya zoom ku muvuduko muto wo gufunga bishobora gutanga ingaruka zidasanzwe.
(4)Hindura vuba uhuze n'ibihe bihinduka
Mu bihe aho urumuri, ibidukikije, n'ingingo bihora bihinduka, nko gufotora mu muhanda, gufata amafoto y'ibyabaye, no gutembera, lense zoom zigufasha guhindura vuba uburyo bwo kureba ibintu kugira ngo uhangane n'ibintu bitandukanye utiriwe uhindura lenses cyane.
2. Varifocalinama zo gukoresha lens
Mu giheindorerwamo za varifocalBitanga uburyo bwinshi bwo korohereza abantu no guhanga udushya mu gufotora, hari ubuhanga bwo gukoresha ibintu bimwe na bimwe bukenewe kugira ngo bakoreshe ubushobozi bwabo bwose.
(1)Huza uburebure butandukanye bw'ibanze ukurikije aho ibintu bibera
Gukoresha uburebure butandukanye bw'ifatizo bishobora gutanga ingaruka zitandukanye ku mashusho, kandi ahantu hatandukanye hasaba uburebure butandukanye bw'ifatizo. Urugero:
Indorerwamo z'indorerwamo nini zikwiriye amafoto y'ahantu nyaburanga n'ay'inyubako, zishimangira imiterere n'ubujyakuzimu bw'ahantu, ariko hagomba kwitonderwa kugira ngo hirindwe kugorama ku mpande z'ishusho;
Uburebure busanzwe bw'inyuma bukwiriye amafoto yo mu muhanda n'amafoto y'ifoto, butanga ishusho ya hafi y'ubuzima bwa buri munsi ndetse bunareba ibidukikije, bigatuma biba bikwiriye amafoto y'inyandiko, hamwe n'ubukana bw'umwimerere n'ubuso bworoshye bw'inyuma;
Indorerwamo za telephoto zikwiriye amafoto yo mu gasozi no mu mikino, zituma umuntu afata amafoto kure ariko akirinda kubangamira umuntu, zigafata utuntu twa kure, kandi zigakuraho amashusho adafite aho ahuriye n’ibintu kugira ngo zigaragaze umuntu.
Indorerwamo za Varifocal zishobora guhuzwa n'uburebure butandukanye bw'inyuma bitewe n'aho ziherereye
(2)Kwibanda ku murongo muremure w'ifatizo
Mu gihe ukoresha lensi ya varifocal, banza wibande ku ntera ya telephoto, hanyuma uhitemo uburebure bukwiye bwo gufata amashusho. Ibi binoza uburyo bwo gufata amashusho neza. Ku ntera ya telephoto, ishusho y'umuntu iba nini mu gihe uburebure bw'aho umuntu aherereye ari buto, bityo bigatuma arushaho gufata amashusho neza. Ibi bifasha cyane cyane mu bihe by'urumuri rw'inyuma cyangwa bigoye, aho gukoresha lensi ya telephoto bituma hakoreshwa uburyo bukwiye bwo gupima amashusho.
(3)Ntukishingikirize cyane kuri zoom,irinde ibirungo by'ubunebwe
Uburyo bworoshye bwo gukoreshaindorerwamo za varifocalbishobora gutuma umuntu akora ibintu bidakunze gukoreshwa, yishingikiriza gusa ku kuzunguruka impeta ya zoom kugira ngo akore amafoto, bigatuma umuntu yishingikiriza cyane kuri zoom kandi bishobora kugabanya imbaraga mu miterere. Ni ngombwa kumenya ko guhindura uburebure bw'ikirahuri cy'ikirahuri bihindura aho umuntu areba, mu gihe kwimura kamera bihindura uko umuntu abona ibintu.
Kwimura kamera hafi cyangwa kure bishobora guteza ingaruka zitandukanye cyane ku buryo bwo gukanda inyuma no gukanda inyuma. Kubwibyo, gukoresha lens ya varifocal bisaba kwimuka cyane kugira ngo ubone inguni nziza yo gufata amashusho hanyuma ugatunganya neza uburebure bw'ifoto kugira ngo ukore amashusho meza cyane.
(4)Witondereigutuzabyaimpera ya telefoto
Indorerwamo za telephoto zikunze kwibasirwa na kamera, bigatuma amashusho adasobanutse neza. Muri ibyo bihe, ni ngombwa kongera umuvuduko wa shutter cyangwa gukoresha ibikoresho byo kubungabunga amashusho. Cyane cyane iyo ukoresha indorerwamo za varifocal zifite uburebure bwa mm 200 cyangwa burebure, ni byiza gukoresha tripod cyangwa igikoresho gisa nayo kugira ngo uhamye indorerwamo. Ibi bigabanya gutigita gufatirwa mu ntoki, bikagira ingaruka nziza ku gufotora, kandi bikongera ubukana bw'ishusho.
Gutuza ni ingenzi cyane mu gufata amashusho hakoreshejwe lensi ya telephoto
(5)Witondere impinduka mu mwobo n'ubujyakuzimu bw'umurima
Ubwinshi bw'amenwa bwa lens nyinshi zoom bugabanuka uko uburebure bwa focal bugenda bwiyongera. Ibi bivuze ko ku mpera ya telephoto, ubwo bwinshi bw'amenwa buba buto, bigabanya ingano y'urumuri rwinjira muri lens kandi bigagabanya ubugari bw'amenwa. Kubwibyo, mu bihe by'urumuri ruto cyangwa iyo ukeneye ubugari bukomeye bw'amenwa, koresha impera ya lens ifite inguni nini cyangwa wongere ISO.
Kugira ngo habeho ingaruka nini za bokeh ku mpera ya telephoto, hashobora kuba hakenewe umwanya munini cyangwa intera yegereye yo kurasa. Byongeye kandi, kugira ngo ugenzure ubujyakuzimu bw'umurima, ushobora kugerageza gusobanukirwa ingaruka z'uburebure butandukanye bw'umurima ku bujyakuzimu bw'umurima. Urugero, gufata amashusho hakoreshejwe uburebure bugufi bw'umurima hanyuma ugashyiramo ibintu byinshi bishobora gutuma inyuma harushaho kuba heza, bityo ukabona uburebure bw'umurima bufite akamaro.
(6)Koresha agapfundikizo k'ijisho mu buryo bukwiye
Indorerwamo za Varifocalifite imiterere igoye cyane n'itsinda rinini ry'indorerwamo z'imbere, bigatuma zishobora kwangirika cyane, ibyo bikaba byatera gushya no kubura urumuri. Gukoresha agapfukamunwa k'indorerwamo z ...
(7)Koresha ibyuma byifashishwa witonze
Muri rusange ntibyemewe gukoresha filters kuri zoom lenses keretse bibaye ngombwa rwose. Mu bidukikije bimwe na bimwe, nko ku nkombe cyangwa mu mazi y'umunyu, filters zo kurinda cyangwa zo gutandukanya zishobora gukoreshwa, ariko gukoresha izindi filters byongera ibibazo byo kugarura urumuri imbere muri lens, bishobora kongera ingaruka mbi.
Mu gihe ukoresha lensi ya varifocal, witondere uburyo urumuri rukoreshwa
Byongeye kandi, uburyo butandukanye bwo gufata amashusho busaba ubuhanga butandukanye mu gukoresha lenses za varifocal. Urugero, mu gufata amashusho mu ngendo, lense ya zoom ishobora gutwikira inguni nini kuri telephoto muri lense imwe; umwobo muto ushobora gukoreshwa mu gufata amashusho yo mu gasozi ku manywa, mu gihe lense ya telephoto iringaniye ifite umwobo munini ishobora gukoreshwa mu gufata amashusho yo mu muhanda nimugoroba.
Mu gusoza,indorerwamo za varifocalbitanga ubushobozi bwo guhanga udushya twinshi, bishyigikira abantu bafotora bashaka improvisation. Ariko, nk'umufotozi, kumenya ubuhanga bwo gufata amafoto ya varifocal ntabwo bihagije; imyitozo myinshi n'uburambe mu gukora ni ingenzi kugira ngo ubu bumenyi buhindukemo ubushishozi, bigufashe gukoresha neza ibyiza bya zoom lenses no guhangana n'ibintu bitandukanye by'umwuga mu buryo bworoshye.
