Ii-fisheye lensiyilensi ye-engeli ebanzi enomklamo okhethekile wokubona, ongabonisa i-engeli enkulu yokubuka nomthelela wokuhlanekezela, futhi ingathwebula inkambu yokubuka ebanzi kakhulu. Kulesi sihloko, sizofunda mayelana nezici, izinhlelo zokusebenza kanye namathiphu okusetshenziswa kwamalensi e-fisheye.

1.Izici zamalensi e-fisheye

(1)Inkambu yokubuka ebanzi

I-engeli yokubuka yelensi ye-fisheye ivamise ukuba phakathi kuka-120 degrees no-180 degrees. Uma kuqhathaniswa namanye amalensi e-engeli ebanzi, amalensi e-fisheye angathwebula isigcawu esibanzi.

(2)Umphumela onamandla wokuhlanekezela

Uma kuqhathaniswa namanye amalensi, ilensi ye-fisheye inomphumela onamandla wokuhlanekezela, okwenza imigqa eqondile esithombeni ibonakale igobile noma igobile, yethula umphumela wesithombe oyingqayizivele futhi omangalisayo.

(3)Ukudlulisa ukukhanya okuphezulu

Ngokuvamile, amalensi e-fisheye anokudlulisa ukukhanya okuphezulu futhi angathola ikhwalithi yesithombe engcono ezimeni zokukhanya okuphansi.

2.Aisicelosamalensi ezinhlanzi

(1)Dala imiphumela ebonakalayo eyingqayizivele

Umthelela wokuhlanekezela wei-fisheye lensingakha imiphumela ebonakalayo eyingqayizivele futhi isetshenziswa kakhulu ezithombeni zobuciko kanye nezithombe zokudala. Isibonelo, izakhiwo ezidubulayo, izimo zezwe, abantu, njll. kunganikeza izithombe zakho ukubukeka okuhlukile.

(2)Izithombe zezemidlalo nezemidlalo

Ilensi ye-fisheye ifanele ukuthwebula izigcawu zezemidlalo, ekhombisa umuzwa we-dynamics kanye nokuthuthukisa umthelela wokunyakaza. Ivame ukusetshenziswa emidlalweni eyeqisayo, umjaho wezimoto neminye imikhakha.

(3)Ukuthwebula izindawo ezincane

Ngenxa yokuthi ingathwebula indawo yokubuka ebanzi kakhulu, amalensi efisheye avame ukusetshenziselwa ukuthwebula izikhala ezincane, njengasendlini, ezimotweni, emigedeni, nezinye izigcawu.

(4)Umphumela wombono ovelele

Ilensi ye-fisheye ingagqamisa umphumela wokubuka eduze nakude, idale umphumela wokubonwayo wokukhulisa ingaphambili kanye nokuncipha kwengemuva, futhi ithuthukise umphumela wesithombe-ntathu.

(5)Ukukhangisa nezithombe zentengiso

Amalensi e-Fisheye aphinde asetshenziswe kabanzi ekukhangiseni nasekuthwebuleni izithombe zentengiso, okungangeza isisho esiyingqayizivele nomthelela obonakalayo emikhiqizweni noma ezigcawini.

3.Amathiphu okusebenzisa i-Fisheye lens

Imiphumela ekhethekile yei-fisheye lensbabe nezindlela ezihlukene zokusebenzisa ezindikimbeni ezahlukene zokudubula, okudingeka zizanywe futhi zenziwe ngokwesimo sangempela. Ngokuvamile, udinga ukunaka amathiphu alandelayo lapho usebenzisa amalensi e-fisheye:

(1)Dala ngemiphumela yokuhlanekezela

Umthelela wokuhlanekezela welensi ye-fisheye ungasetshenziswa ukudala umuzwa wokugoba noma ukuhlanekezelwa okuyihaba kwesigcawu, kuthuthukise umphumela wobuciko wesithombe. Ungazama ukuyisebenzisela ukudubula izakhiwo, izindawo, abantu, njll. ukuze ugqamise izimo zabo ezihlukile.

(2)Zama ukugwema izingqikithi ezimaphakathi

Njengoba umphumela wokuhlanekezela we-lens ye-fisheye ubonakala ngokucacile, isihloko esimaphakathi sinwebeka kalula noma sihlanekezelwe, ngakho-ke lapho uhlanganisa isithombe, ungagxila emaphethelweni noma ezintweni ezingajwayelekile ukuze udale umphumela wokubuka oyingqayizivele.

(3)Naka ukulawula ukukhanya okunengqondo

Ngenxa yezici ezibanzi ze-lens ye-fisheye, kulula ukuveza ukukhanya noma ukuveza ngokweqile izithunzi. Ukuze ugweme lesi simo, ungakwazi ukulinganisela umphumela wokuchayeka ngokulungisa ngokunengqondo imingcele yokuchayeka noma usebenzisa izihlungi.

(4)Ukusetshenziswa ngendlela efanele kwemiphumela yokubuka

Ii-fisheye lensingagqamisa umphumela wokubuka eduze nakude, futhi ingakha umphumela wokubukwayo wokukhulisa ingaphambili kanye nokunciphisa ingemuva. Ungakhetha i-engeli efanele nebanga ukuze ugqamise umphumela wokubuka lapho udubula.

(5)Naka ukuhlanekezela emaphethelweni amalensi

Imiphumela yokuhlanekezela phakathi nendawo nasekupheleni kwelensi ihlukile. Lapho uthwebula, udinga ukunaka ukuthi isithombe esisemaphethelweni e-lens sinjengoba kulindelekile, futhi usebenzise ngokunengqondo ukuhlanekezela onqenqemeni ukuze uthuthukise umphumela wesithombe.
