1.Ese lens yagutse irakwiriye gushushanya?

Igisubizo mubisanzwe ni oya,ubugarimuri rusange ntibikwiriye kurasa amashusho.Intebe nini-ngari, nkuko izina ribigaragaza, ifite umwanya munini wo kureba kandi irashobora gushiramo ibintu byinshi mumashusho, ariko bizanatera kugoreka no guhindura imiterere yinyuguti.

Nukuvuga ko, ukoresheje lens yagutse kugirango urase amashusho bishobora guhindura imiterere yimiterere yinyuguti.Kurugero, ibipimo byumutwe numubiri bisa binini, kandi imirongo yisura nayo izaramburwa kandi igoretse.Ntabwo ari amahitamo meza yo gufotora.

Niba ukeneye gufata amashusho, birasabwa gukoresha uburebure buringaniye cyangwa lens ya terefone kugirango ugere kubintu bifatika kandi bisanzwe byerekana ibintu bitatu.None, lens nini yagutse ikwiriye kurasa ni ikihe?

A ubugariifite uburebure bugufi bwibanze, mubisanzwe hagati ya 10mm na 35mm.Umwanya wacyo wo kureba ni munini kuruta ibyo ijisho ryumuntu rishobora kubona.Birakwiriye kurasa amashusho yuzuye abantu, ahantu nyaburanga, n'amafoto akeneye gushimangira ubujyakuzimu bwumurima n'ingaruka zerekanwa.

Ingero nini yo kurasa

Bitewe nubugari bwagutse bwo kureba, ubugari bugari burashobora gufata ibintu byinshi, bigatuma ishusho ikungahaza kandi igashyirwa hejuru.Ikirangantego kigari gishobora kandi kuzana ibintu haba kure ndetse no hafi yishusho, bigatanga uburyo bwo gufungura.Kubwibyo, linzira ngari zikoreshwa kenshi mu kurasa inyubako, ibibera mumihanda yo mumujyi, ahantu h'imbere, amafoto yitsinda, no gufotora mu kirere.

2.Ihame ryerekana amashusho nibirangaubugari

Amashusho yerekana ubugari bugari bugera ku nguni nini binyuze mu gushushanya sisitemu ya lens hamwe no kwerekana urumuri rw'umucyo (mu guca urumuri binyuze muri sisitemu yihariye, ibibera kure ya axe yo hagati biteganijwe kuri kamera yerekana amashusho cyangwa firime), bityo bigafasha kamera gufata muburyo bwagutse.Iri hame rikoreshwa cyane mumafoto, kwamamaza no mubindi bice.

Turashobora gusobanukirwa ihame ryerekana amashusho ya rugari-ngari duhereye ku ngingo zikurikira:

Sisitemu ya Lens:

Inzira ngarimubisanzwe ukoreshe uruvange rw'uburebure bugufi hamwe na diameter nini.Igishushanyo cyemerera lens yagutse gukusanya urumuri rwinshi kandi ikohereza neza kuri kamera yerekana amashusho.

Igenzura rya Aberration:

Bitewe nigishushanyo cyihariye, lens-rugari ikunze guhura nibibazo byo gukuramo, nko kugoreka, gutatanya, nibindi. Kugira ngo ibyo bibazo bikemuke, ababikora bakoresha ibikoresho bitandukanye bya optique hamwe nubuhanga bwo gutwikira kugirango bagabanye cyangwa bakureho izo ngaruka mbi.

Ingero zerekana:

Ikirangantego kigari kigera ku nguni nini mu kongera inguni hagati yikibanza na hagati yo hagati.Muri ubu buryo, ibintu byinshi bizashyirwa mu ishusho intera imwe, byerekana umurongo mugari wo kureba.

Inzira ngari

Mubikorwa bifatika, dukeneye guhitamo lens yagutse ikwiye dushingiye kumafoto akenewe hamwe nifoto.Muri rusange, amashusho yerekana ibiranga ubugari bwagutse ni ibi bikurikira:

Kugoreka ibintu:

Iyo urasa ibintu byegeranye hamwe naubugari, kugoreka ibintu bibaho, bivuze ko mumashusho yafashwe, ibintu byegeranye bizagaragara binini, mugihe ibintu bya kure bizagaragara ko ari bito.Ingaruka zo kugoreka ibintu zirashobora gukoreshwa kugirango habeho ingaruka zidasanzwe zigaragara, nko gukabya kureba no gushimangira ibintu byimbere.

Umwanya mugari wo kureba:

Intebe yagutse irashobora gufata umurongo mugari wo kureba kandi irashobora gufata ibintu byinshi cyangwa amashusho.Kubwibyo, ubugari bugari bukoreshwa kenshi mu gufata amashusho nkahantu nyaburanga, inyubako, mu ngo, n'imbaga y'abantu bakeneye kwerekana imyumvire yagutse.

Impande zigoramye:

Ingirabuzimafatizo ngari ikunda kugoreka cyangwa ingaruka zigoramye, cyane cyane ku mpande zitambitse kandi zihagaritse.Ibi biterwa nubushobozi bugaragara bwibishushanyo mbonera kandi birashobora gukoreshwa rimwe na rimwe gukora nkana ingaruka zidasanzwe cyangwa imvugo igaragara.

Ubujyakuzimu bwagutse:

Ikirangantego kigari gifite uburebure buto bwo kwibandaho, bityo gishobora gutanga ubujyakuzimu bunini bwumurima, ni ukuvuga, imbere ninyuma bishobora gukomeza ishusho isobanutse.Uyu mutungo ukoraubugariingirakamaro cyane mumafuti aho ubujyakuzimu rusange bwibintu bigomba gushimangirwa.
