AFSHHEYE LONES? Maliseche a fisheye ndi mtundu wa mandala a kamera omwe amapangidwa kuti apange mawonekedwe apamwamba a chochitika, ndi kuwonongeka kwamphamvu kwambiri komanso kosiyana. Mitundu ya fisheye imatha kugwira gawo lalikulu kwambiri, nthawi zambiri mpaka madigiri 180 kapena kupitilira apo, zomwe zimalola wojambulayo kuti agwire malo akuluakulu omwe akuwombera kamodzi.

Mandala a fisheye

Madandaulo a Fisheye amatchedwa kuti atachotsa mawonekedwe awo, omwe amapanga chithunzi chozungulira kapena chowoneka ngati mbiya chomwe chitha kukokomeza. Zotsatira zake zimayambitsidwa ndi momwe mandala amathandizira kuwala pomwe kumadutsa m'magalasi opindika a mandala. Izi zitha kugwiritsidwa ntchito modekha ndi ojambula kuti apange zithunzi zapadera komanso zolimbitsa thupi, komanso zitha kukhala malire ngati chithunzi chowoneka bwino kwambiri chomwe chingafunike.

Magawo a Fisheye amabwera m'mitundu ingapo, kuphatikizapo magalasi ozungulira a fushoni, zozungulira zozungulira zozungulira za fisheye, ndi magalasi a fisheyey. Lililonse la mitundu iyi ya fisheye ye ali ndi mawonekedwe ake apadera ndipo ndioyenera mitundu yosiyanasiyana yojambula.

Mitundu yogwiritsa ntchito mtundu

Magawo ozungulira a fushoni

Mtundu woyamba wa magalasi a fisheyeye anali "magalasi ozungulira" omwe angapangitse chithunzi chozungulira ndi gawo la mademita 180. Ali ndi kutalika kwakanthawi kochepa, kumayambira 7mm mpaka 10mm, omwe amawathandiza kugwira mawonekedwe owoneka bwino kwambiri.
