Nigute wahitamo lens ifite inguni nini ikwiye mugihe ufata amashusho y'ikirere cyuzuye inyenyeri?

Indorerwamo z'ijisho zifite inguni ninibitanga ahantu hagari ho kureba, bigufasha gufata ikirere kinini cyane nijoro hamwe n'ibisobanuro birambuye bya Milky Way mugihe ufotora inyenyeri. None se, nigute wahitamo lenzi ifite inguni nini ikwiye mugihe ufotora ikirere cyuzuye inyenyeri?

Guhitamo lenzi ifite inguni nini ikwiye bisaba gutekereza ku bintu byinshi. Reka turebere hamwe ibintu by'ingenzi bigira ingaruka kuri iyo lenzi:

1.Guhitamo uburebure bw'ifatizo

Uburebure bwa mm 14-24 ni bwo burebure bwiza bwo gufata amalenzi afite inguni nini kugira ngo afate ikirere cyuzuye inyenyeri. Ashobora gufata Milky Way yose mu gihe agenzura neza ubwiza bw'ishusho ku nkengero, bigatuma akoreshwa mu gufata amashusho areba Milky Way n'ahantu hahurira inyenyeri n'ahantu nyaburanga.

Urugero, gukoresha uburebure bwa mm 14 bigufasha gufotora ikirere kinini no gufata ishusho yuzuye ya Milky Way, mu gihe gukoresha uburebure bwa mm 24 bigufasha gufata byinshi mu gice cy’ishusho.

2.Guhitamo aho umuntu ahagarara

Mu gihe ufotora ikirere cyuzuye inyenyeri, ni byiza guhitamo lenzi ifite inguni nini ifite umwobo munini ushoboka, kuko umwobo munini ufite inyungu nini mu duce tudakoresha urumuri rwinshi. Umwobo munini utuma urumuri rugera ku bantu ruhagije, bikarinda inzira z'inyenyeri mu gihe icyarimwe bitanga imiterere ya ISO nke—bigagabanya urusaku kandi bigatanga amashusho asobanutse neza kandi afite ubuziranenge.

Mu gihe ufata amashusho mu kirere cyuzuye inyenyeri, ni byiza guhitamo umwanya ntarengwa wa F2.8 cyangwa urenga. F2.8 ni urwego rw'ibanze rukwiriye ahantu henshi hagaragara amashusho, mu gihe F1.4-1.8 ari yo nziza kandi ikwiriye ahantu hadakoresha urumuri rwinshi.

Mu gihe ufata ikirere cyuzuye inyenyeri ukoresheje lensi y'inguni nini, ugomba gutekereza ku mwenge

3.Kugenzura ubuziranenge bw'ishusho

Indorerwamo z'ijisho zifite inguni niniZikunze kugira ibibazo byo guhinduka kw'amashusho no guhindagurika kw'amashusho; lensi nziza igomba kuba ishobora kugenzura guhinduka kw'amashusho no guhindagurika neza. Mu gihe ureba ikirere cyuzuye inyenyeri, iyo lensi idagenzura guhinduka kw'amashusho neza, imirasire y'umuhengeri ishobora kugaragara hirya no hino ku nyenyeri, mu gihe guhinduka kw'amashusho bizatuma ishusho ihinduka, bigira ingaruka ku ngaruka rusange.

Kubwibyo, ni ngombwa guhitamo lens igaragaza ubushobozi bwo kugenzura neza imiterere y'urumuri no kugoreka. Byongeye kandi, ni ngombwa guhitamo lens ifite ubushobozi bwo hejuru kugira ngo inyenyeri zigaragare nk'aho zigaragara neza kandi zisobanutse neza, hirindwa ko zigaragara nabi.

4.Kwibanda ku buryo bunoze ku manywa

Mu bidukikije byijimye, imikorere ya kamera yo kwibandaho (autofocus) ikunze kuba idakora neza, bigasaba ko habaho guhindura uburyo bwo kwibandaho n'intoki—cyane cyane, gushyira impeta yo kwibandaho ku kimenyetso cy'ubudashira (∞). Ariko, ni ngombwa kumenya ko ikimenyetso cy'ubudashira ku gipimo cy'intera ya lens gikunze kugaragaza amakosa make mu bikorwa kandi ntigishobora kwiringirwa gusa.

Kubwibyo, ni ngombwa guhitamo lenzi ifite ubushobozi bwo gupima impeta y’inyuma kandi ikora urugendo rurerure kugira ngo yorohereze guhindura neza imiterere y’inyuma no kwemeza ko inyenyeri zigaragara neza kandi zityaye.

Gufata amashusho y'ikirere cyuzuye inyenyeri ukoresheje lenzi ifite imiterere yagutse akenshi bisaba kwibanda ku intoki

5.Uburemere n'ingano

Niba ukeneye gutwaralentileIyo uri hanze igihe kirekire, ugomba gutekereza ku buremere n'ingano ya lenti. Urugero, iyo utwaye ibikoresho byo gukora ibikorwa byo hanze bisaba igihe kirekire, nko kuzamuka imisozi cyangwa gutembera, ni ngombwa guhitamo lenti ifite imiterere yoroheje kugira ngo ubashe kugenda woroshye kandi ugabanye umutwaro wawe.

Byongeye kandi, ni ngombwa guhitamo lenti ikubereye ukurikije ingengo y'imari yawe. Niba ufite ingengo y'imari nyinshi, ushobora guhitamo lenti igezweho; icyakora, niba ingengo y'imari yawe ari nke, muri rusange ni byiza guhitamo lenti ijyanye n'ibyo ukeneye by'ibanze byo gufata amashusho.

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.
