Iilensi yeso lenhlanziilensi ene-engeli ebanzi enomklamo okhethekile wokukhanya, engabonisa i-engeli enkulu yokubuka kanye nomphumela wokuhlanekezela, futhi ingabamba insimu yokubuka ebanzi kakhulu. Kulesi sihloko, sizofunda ngezici, izinhlelo zokusebenza kanye namathiphu okusebenzisa amalensi e-fisheye.

1.Izici zamalensi e-fisheye

(1)Insimu ebanzi yombono

I-engeli yokubuka yelensi ye-fisheye ivame ukuba phakathi kwama-degrees angu-120 nama-degrees angu-180. Uma kuqhathaniswa namanye amalensi e-wide-angle, amalensi e-fisheye angathwebula indawo ebanzi.

Ilensi yeso lenhlanzi

(2)Umphumela oqinile wokuhlanekezela

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

(3)Ukudlulisa ukukhanya okuphezulu

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

2.Aukuphindasamalensi e-fisheye

(1)Dala imiphumela ebonakalayo ehlukile

Umphumela wokuhlanekezela weilensi yeso lenhlanziingadala imiphumela ebonakalayo ehlukile futhi isetshenziswa kabanzi ekuthwebuleni izithombe zobuciko kanye nezithombe zokudala. Isibonelo, ukuthwebula izakhiwo, izindawo, abantu, njll. kunganikeza izithombe zakho ukubukeka okuhlukile.

(2)Izithombe zezemidlalo nezemidlalo

Ilensi ye-fisheye ifanelekela ukuthwebula izigcawu zemidlalo, ikhombisa umuzwa wokuguquguquka nokuthuthukisa umthelela wokunyakaza. Ivame ukusetshenziswa kwezemidlalo eziyingozi, umjaho wezimoto kanye neminye imikhakha.

(3)Ukuthwebula izithombe zezindawo ezincane

Ngenxa yokuthi ingathwebula indawo ebanzi kakhulu yokubuka, amalensi e-fisheye avame ukusetshenziselwa ukuthwebula izikhala ezincane, njengangaphakathi endlini, ezimotweni, emihumeni, nakwezinye izigcawu.

(4)Umphumela obonakalayo obonakalayo

Ilensi ye-fisheye ingagqamisa umphumela wokubuka oseduze nakude, idale umphumela obonakalayo wokukhulisa ingaphambili nokunciphisa ingemuva, futhi ithuthukise umphumela onezinhlangothi ezintathu wesithombe.

Ukusetshenziswa kwelensi ye-fisheye

(5)Ukukhangisa kanye nezithombe zezentengiselwano

Amalensi e-Fisheye asetshenziswa kabanzi ekukhangiseni nasekuthatheni izithombe zezentengiselwano, okungangeza ukubonakaliswa okuhlukile kanye nomthelela obonakalayo emikhiqizweni noma ezigcawini.

3.Amathiphu okusebenzisa ilensi ye-Fisheye

Imiphumela ekhethekile yeilensi yeso lenhlanzibanezindlela ezahlukene zokusebenzisa ezindikimbeni ezahlukene zokudubula, okudingeka zizanywe futhi zisetshenziswe ngokwesimo sangempela. Ngokuvamile, udinga ukunaka amathiphu alandelayo uma usebenzisa amalensi e-fisheye:

(1)Dala ngemiphumela yokuhlanekezela

Umphumela wokuhlanekezela welensi ye-fisheye ungasetshenziswa ukudala umuzwa wokugoba noma ukuhlanekezela okweqile kwendawo, okuthuthukisa umphumela wobuciko wesithombe. Ungazama ukusisebenzisa ukuthwebula izakhiwo, izindawo, abantu, njll. ukugqamisa izimo zabo ezihlukile.

(2)Zama ukugwema izingqikithi eziyinhloko

Njengoba umphumela wokuhlanekezela ngelensi ye-fisheye usobala kakhulu, isihloko esiyinhloko silula ukwelulwa noma ukuhlanekezelwa, ngakho-ke lapho ubhala isithombe, ungagxila emaphethelweni noma ezintweni ezingajwayelekile ukuze udale umphumela obonakalayo oyingqayizivele.

Izindlela zokusebenzisa ilensi ye-fisheye

(3)Naka ukulawulwa okunengqondo kokukhanya

Ngenxa yezici ezibanzi zelensi ye-fisheye, kulula ukudalula ukukhanya ngokweqile noma ukudalula izithunzi ngokweqile. Ukuze ugweme lesi simo, ungalinganisa umphumela wokudalula ngokulungisa ngokufanele amapharamitha okudalula noma ukusebenzisa izihlungi.

(4)Ukusetshenziswa okufanele kwemiphumela yokubuka

Iilensi yeso lenhlanziingagqamisa umphumela wokubuka oseduze nokude, futhi ingadala umphumela obonakalayo wokukhulisa ingaphambili nokunciphisa ingemuva. Ungakhetha i-engeli nebanga elifanele ukugqamisa umphumela wokubuka lapho uthwebula.

(5)Naka ukuphambuka emaphethelweni ngelensi

Imiphumela yokuhlanekezela enkabeni nasemaphethelweni elensi ihlukile. Uma uthwebula, udinga ukunaka ukuthi isithombe esisemaphethelweni elensi sinjengoba kulindelekile, bese usebenzisa ngokufanele ukuhlanekezela komphetho ukuthuthukisa umphumela ophelele wesithombe.
