Ngaphantsi kwamanzi izixhobo zokufota ezisetyenziswa yingcali

Umfoti uMarcelo Krause uhambahamba aye kubamba izilwanyana zasendle eziphantsi kwamanzi, ezinje ngeepiranhas kunye nee-caimans. Iphothifoliyo yakhe ibandakanya iifoto eziphantsi kwamanzi ezivela kwiindawo ezinjengePantanal, iKomodo, iMaldives kunye noLwandle oluBomvu.

Izifundo ezihamba ngokukhawuleza, amanzi amdaka kunye nokubonakala okufipheleyo zezona zithintelo ziphambili phakathi komfoti kunye nokwenziwa okucacileyo. Ukuhamba ngaphantsi kwamanzi ngumzabalazo wokufumana izixhobo ezifanelekileyo zezindlu, iilensi ezibanzi kakhulu, kunye nezona zicwangciso zilungileyo ngokwesantya se-shutter, i-ISO, kunye nobude obugxile kuyo.

Iipanorama zangaphantsi kwamanzi kunye neTokina DX 10-17mm f / 3.5-4.5 lens fisheye

I-Canon kunye ne-Nikon APS-C DSLRs zinokudityaniswa nale lens ikhankanywe ngasentla yeTokina, yiyo loo nto izisa phambili ithuba lokuthimba icandelo lokujonga ikona yeedigri ezili-180 kwikona ye-10mm.
Iilensi ze-Fisheye zivumela ubugqwetha obungakholelekiyo, ukuba lukhetho olufanelekileyo kwii-panorama ezingama-360 ze-VR. Ukongeza, amandla okusondeza nawo adityanisiwe kule Tokina AT-X 107 AF DX 10-17mm f / 3.5-4.5 fisheye lens.

Ukuphathwa kwamanzi kulula ngokwaneleyo, nangona umzimba wenziwe ngentsimbi. Nangona kunjalo, iilensi azinzima kangako kwaye ubungakanani bazo obudibeneyo banceda abasebenzisi ukuba bacinge ngemiceli mngeni yabo engaphantsi kwamanzi, hayi abo banokubanjiswa zizityalo ezijijekileyo.

Ubunzulu bentsimi abunakuthelekiswa nanto, ngenxa yeemeko apho kufuneka isebenze khona ikhamera. Ngapha koko, ubude obufutshane obugxile kwenza i-autofocus yangaphakathi ivuthe ngokukhawuleza, egqibeleleyo ukufota phantsi kwamanzi.

Ukusebenza kukaTokina fisheye uthe ukuphucula ubuchule

Ukuhanjiswa kombala nangona kunjalo kuphezulu, kodwa kunokulungiswa kunye nezisombululo ezinikezelweyo zasemva kokuqhubekeka. Ezi zixhobo zesoftware zinokujika iifoto ezigwenxa ezibanzi zibe yimifanekiso ye-rectilinear.

Imekobume engaphantsi kwamanzi ifuna umbono obanzi, kuba akukho lula kakhulu ukuthatha iifoto zezilwanyana zasendle. Ngaphaya koko, ukuvutha kunye nolawulo lwesiporho kule lens kucima imithombo yokukhanya eqinileyo ehlangatyezwe ziimeko ezinamanzi.

Useto lokufota ngaphantsi kwamanzi luvela kuMarcelo Krause

NgokukaMarcelo Krause, ikhamera yakhe yeNikon D2X yayisetelwe kwi-ISO 400 yezi foto. Ukwacebisa ukuba isantya se-shutter kufuneka sikhawuleze njengemvume yokuvumelanisa i-flash, kule khamera ingu-1 / 250th.

Iilensi zeTokina ziza ziluncedo ngenxa yokubonakala kwamanzi anzulu. Umbono kukuba kufutshane kangangoko kunokwenzeka kwisifundo kwaye iilensi ezibanzi zeekona zibonelela ngokuchanekileyo.

Ikhamera yeNikon D2X inee-megapixels eziyi-12.4 ezifanelekileyo, ezinemowudi yokubeka phambili, iifreyimu ezintlanu ngomzuzwana ukudubula okuqhubekayo kwisisombululo esipheleleyo, kunye nolawulo olupheleleyo lwekhamera, ezilungele ukuthatha iifoto ezingalindelwanga kwiindawo eziyingozi.

Ngaphantsi kwamanzi strobe kunye nezixhobo zezindlu ziyafuneka

I-Aquatica D2X izindlu ezingaphantsi kwamanzi sisisombululo esikhethwe nguMarcelo Krause ngokuthatha ifoto yakhe. Ngokucacileyo, ibonelela ngokufikelela ngokupheleleyo kwimisebenzi yolawulo lwekhamera.

Ifaka ialam yomswakama, amandla eelensi ezininzi, kunye neelensi ezikhawulezayo kunye nokutshintsha kwezibuko, esi sixhobo sezindlu sisebenzisa isibonisi sokubonelela ngombono omkhulu kunye oqaqambileyo.

I-Inon Z-240 Underwater Strobe iyafumaneka backscatter.com

Ngokubhekisele kwi-strobe, umfoti wayisebenzisa i-Inon Z-240. Iyakwazi ukuhambisa ukukhanya nangaphandle kwesisasazi, esi strobe sinesetyhula ebanzi yokugubungela umqadi we-100, ubuncinci bexesha lokuphinda usebenzise imizuzwana eyi-1.6, isilawuli se-EV, kunye nezinye izinto ezenzelwe ukufota ngaphantsi kwamanzi.
Izixhobo zobungcali ngokuqinisekileyo ziya kugubungela iziseko zokufota ngaphantsi kwamanzi. Kwelinye icala, iifoto ezinomdla zihlala zicela inkalipho, umonde kunye nobuchule beendlela zokufota.
