2.Chii chinoshandiswa ne-wide-angle lens?

Wide-angle lenses anonyanya kushandisa zvinotevera:

Simbisa mhedzisiro yepedyo-up

Nekuti iyo yakafara-ekona lens ine yakakura kudzika kwemunda, inogona kuwana yakasimba yepedyo-kumusoro maitiro.Kushandisa lens yakakura-ekona kupfura kunogona kuita kuti zvinhu zvemberi zvive zvakajeka sezvinhu zviri kure, kukudza zvinhu zvemberi, uye kuburitsa hudzamu huri pachena hwekuita kwemunda, zvichiwedzera pfungwa yekuisa uye matatu-dimensionality kumufananidzo wose.

Iyo yakafara-ekona lenzi

Wedzera maonero maitiro

Paunenge uchishandisa awide-angle lens, pachava nepedo-yakakura uye kure-duku, iyo inowanzonzi "fisheye effect".Maonero aya anogona kuita kuti chinhu chakatorwa mifananidzo chionekwe chiri pedyo nemucherechedzi, zvichipa vanhu pfungwa yakasimba yenzvimbo uye matatu-dimensionality.Naizvozvo, marenzi-makona marefu anowanzo shandiswa mumifananidzo yekuvaka kuratidza hukuru uye kukurumidza kwechivako.

Bata zvimiro zvakakura

Lens yakakura-angle inokwanisa kuratidza kona yakafara yekuona, ichibvumira vatori vemifananidzo kutora mifananidzo yakawanda, yakadai semakomo ari kure, makungwa, panoramas eguta, nezvimwewo. Inogona kuita kuti mufananidzo wacho uwedzere-dimensional uye uvhure, uye wakakodzera kupfura. zviitiko zvinoda kuratidza pfungwa yenzvimbo yakakura.

Special mafoto applications

Wide-angle lenses inogona zvakare kushandiswa kune yakakosha kutora mafoto, senge kupfura-padhuze mapikicha kana hunhu zvinyorwa, izvo zvinogona kugadzira yakajeka uye yechokwadi zviitiko.

3.Musiyano uripo pakati pehupamhi-ekona lens uyenormallenzi

Wide-angle lens uye akajairwa lenzi ndiwo akajairika lens mhando mukutora mifananidzo.Vanosiyana muzvikamu zvinotevera:

Mifananidzo yakatorwa ne-wide-angle lens vs. mapikicha akatorwa neakajairika lens

Viewable range

A wide-angle lensine nzvimbo yakakura yekuona uye inogona kutora mamwe nharaunda uye ruzivo.Izvi zvinobatsira kupfura nzvimbo, nzvimbo dzemukati, kana zviratidziro uko kumashure kunoda kusimbiswa.

Mukuenzanisa, iyo ndima yekuona lens akajairwa idiki uye yakanyatsokodzera kupfura ruzivo rwenzvimbo, senge mapikicha kana zviratidziro zvinoda kusimbisa nyaya.

Firimu angle

Lens yakakura-ekona inopfura kubva pakona yakafara pane yenguva dzose.Iyo yakafara-ekona lens inogona kutora yakakura siyana yezviratidziro uye inobatanidza zvizere chiitiko chakafara mufuremu.Mukuenzanisa, malenzi akajairwa ane kona yakatetepa yekupfura uye akakodzera kutora zviratidziro zviri pakati nepakati.

Pmaonero maitiro

Sezvo kupfura kwelenzi yakakura-ekona yakakura, zvinhu zviri pedyo-pedyo zvinoonekwa zvakakura nepo kuseri kuchiita kunge kudiki.Maonero aya anonzi "wide-angle distortion" uye anokonzeresa kuti zvinhu zviri padhuze zviite kukanganisa uye kuita sezvine mukurumbira.

Kusiyana neizvi, maitiro ekuona kwema lenzi akajairika anonyanya kuitika, uye chiyero chepedyo-kumusoro uye kumashure chiri padyo neiyo chaiyo yekutarisa mamiriro.

4.Musiyano uripo pakati pehupamhi-ekona lens uye fisheye lens

Musiyano uripo pakati pe-wide-angle lens uye fisheye lens kunyanya uri mumunda wekuona uye kukanganisa maitiro:

Viewable range

A wide-angle lenskazhinji ine nzvimbo yakafara yekuona pane yenguva dzose lens, ichiibvumira kutora yakawanda yechiitiko.Makona ayo ekuona anowanzo pakati pe50 madhigirii uye 85 madhigirii pane 35mm yakazara-frame kamera.

Iyo fisheye lens ine nzvimbo yakafara kwazvo yekuona uye inogona kutora zvimiro zvinodarika 180 madhigirii, kana kunyange panoramic mifananidzo.Naizvozvo, kona yaro yekuona inogona kunge yakakura kwazvo kupfuura yelenzi yakakura-ekona, iyo inowanzoita 180 madhigirii pane yakazara-frame kamera.

Mifananidzo yakatorwa nefisheye lens

Distortion effect

Wide-angle lenses inogadzira kushomeka kushoma uye inogona kuratidza echokwadi chiyero chezviitiko uye maumbirwo emitsetse.Inowedzera zvishoma zvinhu zviri pedyo, asi kukanganisa kwese kwese kudiki.

Iyo fisheye lens ine mhedzisiro yekukanganisa iri pachena, iyo inoratidzirwa nekuwedzera kuri pachena kwezvinhu zviri pedyo, nepo zvinhu zviri kure zvichidzika, zvichikonzera chiitiko chakakombama kana chakatenderera, chinoratidza chakasiyana chehove.

Chinangwa uye anoshanda mamiriro

Iyo yakafara-ekona lens inokodzera kupfura mifananidzo inoda nzvimbo yakakura yekuona, senge nyika, zvivakwa zvemudhorobha, kupfura kwemukati, nezvimwewo. Inowanzoshandiswa kutora nzvimbo dzakakura dzenzvimbo uchichengeta pfungwa yekuona uye realism.

Kusiyana neizvi, malenzi ehove akakodzera kugadzira akasiyana ekuona maitiro uye anogona kuburitsa zvinokanganisa zvinokanganisa munzvimbo dzakatarwa, senge nzvimbo diki dzemukati, nzvimbo dzemitambo, kana zvisikwa zvehunyanzvi.
