Umgodi omkhuluilensi yeso lenhlanziinezici zokuvula okukhulu kanye ne-engeli yokubuka ebanzi kakhulu, engathwebula izigcawu ezibanzi kakhulu. Inezinzuzo eziyingqayizivele kanye nezinhlelo zokusebenza zokudala ezithombeni zangaphakathi futhi ingaletha umthelela omkhulu obonakalayo esithombeni.
1.Izimo zokusetshenziswa kwelensi ye-fisheye enkulu evulekile ezithombeni zangaphakathi
Amalensi amakhulu e-fisheye avulekayo afanelekela izindawo zangaphakathi ezinesikhala esilinganiselwe. Izici zawo ze-engeli ebanzi kakhulu kanye ne-aperture enkulu kungathuthukisa ikhono lokudubula ezindaweni ezinokukhanya okuphansi futhi kube nezinhlelo zokusebenza ezihlukile ekuthwebuleni izithombe zangaphakathi. Okulandelayo, ake sibheke izimo ezivamile zokusetshenziswa kwamalensi amakhulu e-fisheye avulekayo ekuthwebuleni izithombe zangaphakathi.
A.Ukwakhiwa kwezakhiwo kanyesijubanepi-hotography
Amalensi amakhulu e-fisheye avulekayo ngokuvamile ane-engeli yokubuka engu-180° noma ebanzi kakhulu, engathwebula indawo ebanzi endaweni encane kakhulu yokudubula, kuyilapho ithuthukisa umuzwa wendawo nowe-dynamic wesithombe ngomphumela onamandla wokuhlanekezela. Lesi sici sifaneleka kakhulu ezigcawini zokudubula ezifana nezakhiwo zesakhiwo zangaphakathi, ukwakheka kwesikhala sangaphakathi, kanye nemininingwane yokuhlobisa.
Isibonelo, lapho kudutshulwa imihubhe yangaphakathi noma amakamelo, amalensi e-fisheye angalula imiphetho futhi awahlanganise aye phakathi nendawo, adale umphumela wokubuka okweqile, okwenza isithombe sibonakale sivulekile futhi sinezinhlangothi ezintathu.
B.Ukudubula okubanzi ngaphakathi endlini
I-engeli yokubuka ebanzi kakhulu yembobo enkuluilensi yeso lenhlanziifaneleka kakhulu ekuthatheni izithombe ze-panoramic zangaphakathi, ikakhulukazi uma udinga ukuthwebula ingaphakathi legumbi lonke noma isakhiwo.
Isibonelo, ilensi ye-fisheye ingamboza igumbi lonke ngesikhathi esisodwa, futhi ungathola umbono ophelele ngaphandle kokuhambisa ikhamera. Lo msebenzi usetshenziswe kabanzi ekuthwebuleni izithombe ze-VR panoramic, amakhaya ahlakaniphile, kanye nokuzulazula kwamarobhothi.

C.Ukusebenza kwezithombe ezindaweni ezinokukhanya okuphansi
Amalensi amakhulu e-fisheye avulekayo ngokuvamile anenani elikhulu le-f-stop, eliwavumela ukuthi alondoloze ikhwalithi yesithombe enhle ezimweni zokukhanya okuphansi, okubaluleke kakhulu ekuthwebuleni izithombe zangaphakathi. Lesi sici sifaneleka kakhulu ezigcawini ezivamile zokukhanya okuphansi ngaphakathi, njengamakamelo okuhlala afiphele, ingaphakathi lezindawo zokudlela ebusuku, noma imihubhe ekhanyayo ephansi. Ngaphezu kwalokho, ukwakheka okukhulu kwe-fisheye lens kusiza futhi ukuthuthukisa ukukhanya nokucaca kwesithombe.
D.Izithombe zemicimbi kanye namadokhumentari
Amalensi amakhulu e-fisheye avulekayo nawo avame ukusetshenziswa ezithombeni zemicimbi kanye nezithombe ezibhaliwe. Afaneleka ukuthatha izithombe zeqembu noma izigcawu ezidinga amarekhodi aphelele emvelo (njengokuhlelwa kwehholo ledili). Amalensi amakhulu e-fisheye avulekayo asetshenziswa emishadweni, emaphathini, emakhonsathini nakweminye imicimbi.
Ukuvulwa kwazo okukhulu kungaqinisekisa isivinini se-shutter ekukhanyeni okuphansi, kanyeiso lenhlanziumbono ungabamba umoya kanye nokusebenzisana kwabantu ngesikhathi esisodwa. Isibonelo, lapho kuthwetshulwa izithombe zemicimbi yangaphakathi, umbono we-fisheye + ukudubula okuqhubekayo okusheshayo kungamisa isikhathi sokuphonsa amacembe namaribhoni, kuthuthukise umuzwa oguquguqukayo wesithombe.

E.Ezentengiselwano kanyepumkhiqizopi-hotography
Amalensi amakhulu e-fisheye angasetshenziswa futhi ekuthathweni kwezithombe zezentengiselwano zangaphakathi kanye nemikhiqizo. Umphumela wokuhlanekezela kwamalensi e-fisheye ungaletha umbono oyingqayizivele kanye nomphumela wokuhlanekezela kwesithombe, okwenza izigcawu zangaphakathi zibe nomphumela ohlukile wokubuka. Lo mphumela ungasetshenziswa ukugqamisa izinto ezithile esithombeni noma ukudala umthelela obonakalayo omangalisayo.
Isibonelo, ukuhlanekezelwa kwe-fisheye kungasetshenziswa ukugqamisa inani lezimpahla (njengemikhiqizo emincane kagesi, ubucwebe), noma ukuhlanganisa indawo ukuze kuboniswe ukusetshenziswa kwezimo zomkhiqizo.
F.Izithombe zobuciko zokudala
Umphumela wokuhlanekezela ngelensi enkulu ye-fisheye evulekayo ungaletha imiphumela ebonakalayo egqamile neyingqayizivele ezigcawini zangaphakathi, kufaka umqondo wobuciko kanye nobuciko ezithombeni zangaphakathi, kudale umthelela oqinile wokubuka.
Isibonelo, ngokusebenzisa ukuphambuka kwe-barrel lens ye-fisheye, ungalula imilenze noma isizinda lapho uthwebula izithombe ukuze udale umuzwa ongavamile; endaweni ebushelelezi noma esibukweni, ilensi ye-fisheye ingathwebula izithombe ezihlukile ezibukisiwe ukuze kuthuthukiswe isithakazelo sesithombe.
Ngamafuphi, umbono we-engeli ebanzi kakhulu kanye nomphumela wokuhlanekezela oyingqayizivele we-large apertureilensi yeso lenhlanziikwazi ukuthwebula imininingwane nesimo sezindawo zangaphakathi okunzima ukuziveza ngamalensi endabuko. Kungakhathaliseki ukuthi ukudubula okune-panoramic noma ukudala ngobuciko, ilensi ye-fisheye inganikeza imiphumela ebonakalayo emangalisayo.

2.Izinyathelo zokuphepha zokusebenzisa amalensi e-fisheye avuleke kakhulu
Nakuba amalensi e-fisheye enikeza amathuba amaningi okudala, imiphumela yawo yokuphambuka ingaletha nezinselele ezithile. Ngakho-ke, abathwebuli bezithombe kudingeka babe nolwazi ngamakhono athile kanye nezinyathelo zokuphepha lapho besebenzisa amalensi e-fisheye:
Naka ukulawula ukuhlanekezela: Ukuphambuka kwamalensi e-fisheye kubonakala kakhulu emaphethelweni esithombe. Umthwebuli wezithombe udinga ukulungisa ukwakheka ngaphambi kokuthatha izithombe, aqinisekise ukuthi into ebekwe phakathi nesithombe, agweme ukubeka izinto ezibalulekile eduze kakhulu nomphetho wesithombe, futhi agweme izinto ezisemaphethelweni eziphazamisa ukugxila.
Gwema ukwelula ngokweqile: Uma uthatha izithombe, ubuso bomuntu oseduze nelensi buzobangela ukuguquka okukhulu, ngakho-ke udinga ukubusebenzisa ngokucophelela. Ukuze uthwebule izithombe, ilensi enkulu ye-fisheye evulekile ifaneleka kakhulu ekuthwebuleni izithombe zomzimba wonke noma zemvelo.
Naka ukujula kwensimu kanye nokukhetha ukugxila: Nakuba imbobo enkulu ingafiphaza ingemuva, ubude obuqondile belensi ye-fisheye bufushane kakhulu futhi ukujula kwangempela kwensimu kubanzi, kudinga ukugxila okuqondile kulokho okukhulunywa ngakho (njengamehlo esithombe).
Naka amathiphu endawo enokukhanya okuphansi: Ungasebenzisa imbobo enkulu ukwandisa isivinini se-shutter, kodwa udinga ukunaka umsindo we-ISO ophezulu. Uma kudingeka, ungasebenzisa i-tripod noma wandise ukukhanya kwe-ambient (njengokusebenzisa isibani sokugcwalisa).
Ukusetshenziswa kwelensi ye-fisheye enkulu evulekile endaweni enokukhanya okuphansi
Ngamafuphi, imbobo enkuluamalensi e-fisheyeingaxazulula inkinga yokulinganiselwa kwesikhala futhi idale imiphumela ephawulekayo ekuthwebuleni izithombe zangaphakathi. Zifaneleka kakhulu izigcawu ezidinga umbono oweqile, ukuqoshwa okunamandla noma ukuvezwa kobuciko. Kufanele kuqashelwe ukuthi ukuhlanekezela kanye nokusebenza kahle kudingeka kulinganiswe ngaphambi kokusetshenziswa. Amalensi e-Fisheye afaneleka kakhulu ezintweni ezidala imiphumela ebonakalayo ehlukile, kodwa hhayi ukuqoshwa okungokoqobo.
Imicabango Yokugcina:
UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kwamalensi e-fisheye, asetshenziswa kabanzi emikhakheni eyahlukene. Uma unesithakazelo noma unesidingo samalensi e-fisheye, sicela usithinte ngokushesha okukhulu.
