1.Lens yakakura-ekona yakakodzera mifananidzo here?

Mhinduro kazhinji ndeyekuti kwete,wide-angle lenzikazhinji haakodzeri kupfura mifananidzo. Iyo yakafara-ekona lenzi, sekureva kunoita zita, ine yakakura ndima yekuona uye inogona kusanganisira yakawanda nzvimbo mupfuti, asi zvakare inokonzeresa kukanganisa uye deformation yevatambi vari pamufananidzo.

Kureva kuti, kushandisa wide-angle lens kupfura mifananidzo inogona kukanganisa zviso zvevatambi. Semuenzaniso, zviyero zvemusoro nemuviri zvinotaridzika zvakakura, uye mitsetse yechiso icharebeswa uye yakakanganiswa. Iyi haisi sarudzo yakanaka yekutora mifananidzo.

Kana iwe uchida kutora mifananidzo, zvinokurudzirwa kushandisa yepakati yakatarisa kureba kana telephoto lens kuti uwane inogoneka uye yakasikwa matatu-dimensional portrait effect. Saka, chii chinonzi wide-angle lens chakakodzera kupfura?

A wide-angle lensine hurefu hwefocal hupfupi, kazhinji pakati pe10mm ne35mm. Munda waro wekuona wakakura kudarika izvo ziso remunhu rinogona kuona. Yakakodzera kupfura mamwe maratidziro akazara, nzvimbo dzakafara, uye mafoto anoda kusimbisa kudzika kwemunda uye maonero maitiro.

Wide-angle lens kupfura mufananidzo

Nekuda kwenzvimbo yakafara yekuona, yakafara-ekona lens inogona kutora zvimwe zvinhu, zvichiita kuti mufananidzo upfume uye uwedzere kurongeka. A wide-angle lens anogonawo kuunza zvinhu zviri kure nepedyo mumufananidzo, zvichipa pfungwa yekuvhurika. Naizvozvo, marenzi akafara-ekona anowanzo shandiswa kupfura zvivakwa, zviratidziro zvemumigwagwa yemuguta, nzvimbo dzemukati, mapikicha emapoka, uye mafoto emuchadenga.

2.Iyo yekufungidzira musimboti uye maitiro ewide-angle lenzi

Kufungidzira kwelenzi yakakura-ekona kunoita kuti pave neyakakura-ekona mhedzisiro kuburikidza nekugadzirwa kweiyo lens system uye fungidziro yekona yechiedza (nekupfuura mwenje kuburikidza neiyo chaiyo lens system, chiitiko chiri kure nepakati axis inoratidzwa pa. kamera yemufananidzo kana firimu), zvichiita kuti kamera itore kune yakafara maonero. Iyi nheyo inoshandiswa zvakanyanya mukutora mifananidzo, kushambadza uye mamwe minda.

Isu tinogona kunzwisisa iyo yekufungidzira musimboti weyakafara-ekona lenses kubva kune anotevera maficha:

Lens system:

Wide-angle lenzikazhinji shandisa musanganiswa weupfupi wakatarisa kureba uye hombe dhayamita lenzi. Iyi dhizaini inobvumira iyo yakafara-ekona lens kuunganidza yakawedzera mwenje uye nekuifambisa zvakanaka kune kamera sensor yemufananidzo.

Aberration control:

Nekuda kweiyo yakakosha dhizaini, yakafara-ekona lenses anowanzo kutarisana nedambudziko rekupokana, senge kukanganisa, kupararira, nezvimwe. Kuti vagadzirise nyaya idzi, vagadziri vanoshandisa zvakasiyana-siyana optical components uye coating tekinoroji kuderedza kana kubvisa izvi zvakaipa mhedzisiro.

Projection angle:

Iyo yakafara-ekona lens inowana yakafara-ekona maitiro nekuwedzera kona pakati pechiitiko uye yepakati axis yelens. Nenzira iyi, mamwe maratidziro achaverengerwa mumufananidzo uri chinhambwe chakafanana, kuratidza nzvimbo yakafara yekuona.

Iyo yakafara-ekona lenzi

Mumashandisirwo anoshanda, isu tinofanirwa kusarudza yakakodzera-yakafara-ekona lens zvichibva pane chaiyo yekutora mafoto zvinodiwa uye zviratidziro. Kazhinji kutaura, maitiro ekufungidzira e-wide-angle lenses ndeaya anotevera:

Kukanganiswa kwemaonero:

Pakupfura vhara zvinhu newide-angle lens, kukanganisa kwemaonero kunoitika, izvo zvinoreva kuti mumufananidzo wakatorwa, zvinhu zviri pedyo zvichaonekwa zvakakura, asi zvinhu zviri kure zvichaonekwa zviduku. Mhedzisiro yekukanganiswa kwemaonero inogona kushandiswa kugadzira yakasarudzika yekuona maitiro, sekuwedzeredza maonero uye kusimbisa zvinhu zvemberi.

Broad maonero:

Iyo yakafara-ekona lens inogona kutora nzvimbo yakafara yekuona uye inogona kutora mamwe mamiriro kana zviratidziro. Naizvozvo, ma-lens akafara-makona anowanzo shandiswa kupfura zvimiro zvakaita senzvimbo, zvivakwa, mukati, uye mhomho dzinoda kuratidza pfungwa yenzvimbo yakafara.

Micheto yakakombama:

Wide-angle lenses anojaira kumucheto kukanganisa kana curved mhedzisiro, kunyanya pamipendero yakachinjika uye yakatwasuka. Izvi zvinokonzerwa nekusakwana kwechimiro chekugadzira lens uye dzimwe nguva inogona kushandiswa kugadzira nemaune chimiro chakakosha kana mutauro wekuona.

Kuwedzera kudzika kwemunda:

Iyo yakafara-ekona lens ine diki yekutarisa kureba, saka inogona kuburitsa yakakura kudzika kwemunda, kureva kuti, zvese kumberi nekumashure zvinotaridzika zvinogona kuchengetedza mufananidzo wakajeka. Iyi pfuma inoitawide-angle lenziinobatsira zvikuru mumapfuti apo hudzamu hwese hwechiitiko hunoda kusimbiswa.
