Ii-lens ye-fisheyeyi-lens ebanzi-engile enoyilo olukhethekileyo lwe-optical, enokubonisa i-engile enkulu yokujonga kunye nesiphumo sokuphazamiseka, kwaye inokubamba intsimi ebanzi kakhulu yokujonga. Kweli nqaku, siza kufunda malunga neempawu, izicelo kunye neengcebiso zokusetyenziswa kweelensi ze-fisheye.

1.Iimpawu zeelensi zamehlo eentlanzi

(1)Indawo ebanzi yokujonga

I-angle yokujonga i-lens ye-fisheye idla ngokuba phakathi kwe-120 kunye ne-180 degrees. Xa kuthelekiswa nezinye iilensi ezibanzi, iilensi zefisheye zinokubamba indawo ebanzi.

(2)Isiphumo esinamandla sokugqwesa

Xa kuthelekiswa nezinye iilensi, i-lens ye-fisheye inefuthe elinamandla lokugqwesa, okwenza imigca ethe tye emfanekisweni ibonakale igobile okanye igobile, ibonisa umphumo oyingqayizivele kunye omangalisayo.

(3)Ukuhanjiswa kokukhanya okuphezulu

Ngokubanzi, iilensi ze-fisheye zinokugqithisela ukukhanya okuphezulu kwaye zinokufumana umgangatho ongcono womfanekiso kwiimeko zokukhanya okuphantsi.

2.Aisicelosiilensi zamehlo

(1)Yenza iziphumo ezibonwayo ezizodwa

Isiphumo sokugqwethwa kwei-lens ye-fisheyeinokudala iziphumo ezibonwayo ezizodwa kwaye isetyenziswa kakhulu kwimifanekiso yobugcisa kunye nokufota ngokuyilayo. Umzekelo, izakhiwo ezidubulayo, iimbonakalo-mhlaba, abantu, njl.njl. zinokunika imifanekiso yakho inkangeleko eyahlukileyo.

(2)Ezemidlalo kunye neefoto zezemidlalo

I-lens ye-fisheye ifanelekile ukubamba imiboniso yezemidlalo, ibonisa ingqiqo ye-dynamics kunye nokuphucula impembelelo yokunyakaza. Ngokuqhelekileyo isetyenziswa kwimidlalo egqithisileyo, umdyarho weemoto kunye namanye amabala.

(3)Ukufota iindawo ezincinci

Ngenxa yokuba inokubamba indawo yokujonga ebanzi kakhulu, iilensi ze-fisheye zihlala zisetyenziselwa ukubamba iindawo ezincinci, ezinje ngaphakathi, iimoto, imiqolomba kunye nezinye iziqendu.

(4)Isiphumo sombono obalaseleyo

Ilensi ye-fisheye inokugqamisa isiphumo sembono yakufutshane nakude, yenze imbonakalo yokwandisa umphambili kunye nokunciphisa imvelaphi, kwaye iphucule isiphumo se-dimensional emithathu yefoto.

(5)Intengiso kunye neefoto zentengiso

Iilensi ze-Fisheye zikwasetyenziswa ngokubanzi kwiintengiso kunye neefoto zentengiso, ezinokongeza intetho ekhethekileyo kunye neempembelelo ezibonakalayo kwiimveliso okanye kwimiboniso.

3.Iingcebiso zokusetyenziswa kwe-Fisheye lens

Iziphumo ezizodwa zei-lens ye-fisheyezineendlela ezahlukeneyo zokusetyenziswa kwimixholo eyahlukeneyo yokudubula, ekufuneka izame kwaye iqheliselwe ngokweyona meko. Ngokubanzi, kufuneka ubeke ingqalelo kwezi ngcebiso zilandelayo xa usebenzisa iilensi ze-fisheye:

(1)Yenza ngeziphumo ezigqwethekileyo

Impembelelo ephazamisayo ye-lens ye-fisheye ingasetyenziselwa ukudala ingqiqo ye-curvature okanye ukuphazamiseka okugqithisiweyo kwendawo, ukuphucula umphumo wobugcisa bomfanekiso. Ungazama ukuyisebenzisa ukudubula izakhiwo, imihlaba, abantu, njalo njalo ukuqaqambisa iimilo zabo ezizodwa.

(2)Zama ukuyiphepha imixholo esembindini

Ekubeni impembelelo ephazamisayo ye-lens ye-fisheye ibonakala ngakumbi, umxholo ophakathi ulula okanye uphazamisekile, ngoko xa uqulunqa umfanekiso, unokugxila kwimida okanye izinto ezingaqhelekanga ukwenza umphumo obonakalayo oyingqayizivele.

(3)Nika ingqalelo kulawulo olufanelekileyo lokukhanya

Ngenxa yeempawu ezibanzi ze-lens ye-fisheye, kulula ukugqithisa ukukhanya okanye ukugqithisa izithunzi. Ukuze ugweme le meko, unokulinganisa isiphumo sokuvezwa ngokuhlenga-hlengisa ngokufanelekileyo iiparamitha zokuvezwa okanye ukusebenzisa izihluzi.

(4)Ukusetyenziswa ngokufanelekileyo kweempembelelo zembono

Ii-lens ye-fisheyeinokuqaqambisa isiphumo sembono yakufutshane nakude, kwaye inokudala isiphumo esibonakalayo sokwandisa umphambili kunye nokunciphisa imvelaphi. Unokukhetha i-engile efanelekileyo kunye nomgama ukugqamisa umphumo wembono xa udubula.

(5)Nikelani ingqalelo ekuphazanyisweni kwimida yelensi

Iimpembelelo eziphazamisayo kwiziko kunye nomda we-lens zihlukile. Xa udubula, kufuneka ubeke ingqalelo ukuba umfanekiso osemaphethelweni welensi ulindeleke, kwaye usebenzise ngokunengqiqo ukugqwetheka komphetho ukuphucula umphumo wesithombe.
