UFiliphu Novotny Ku-WWDC yalo nyaka, i-Apple yethule izindaba eziningi ukuthi ilungiselela inguqulo entsha yesistimu yeselula ye-iOS 8. sasingasekho isikhathi futhi uma kunjalo, uCraig Federighi ubalule kafushane nje. Nokho, onjiniyela bayaqaphela lezi zici, futhi kuleli sonto bathole eyodwa. Inenketho yokulawula ikhamera ngesandla.
Kusukela ku-iPhone yokuqala kuya kweyakamuva kakhulu, abasebenzisi bebejwayele ukuthi yonke into yenzeke ngokuzenzakalelayo kuhlelo lokusebenza lwekhamera. Yebo, kungenzeka ukushintshela kumodi ye-HDR futhi manje nakumodi ye-panoramic noma yokunyakaza kancane. Kodwa-ke, uma kuziwa ekulawuleni ukuchayeka, izinketho bezilinganiselwe kakhulu okwamanje - ngokuyisisekelo, besingakwazi ukukhiya i-autofocus kanye nemitha yokuchayeka endaweni eyodwa.
Nokho, lokhu kuzoshintsha ngesistimu elandelayo yeselula. Hhayi-ke, okungenani ingashintshwa kusetshenziswa izinhlelo zokusebenza zezinkampani zangaphandle. Nakuba imisebenzi yeKhamera eyakhelwe ngaphakathi, ngokohlobo lwamanje lwe-iOS 8, izokhula kuphela ngokuba nokwenzeka kokulungiswa kokuchayeka (+/- EV), i-Apple izovumela izinhlelo zokusebenza zezinkampani zangaphandle ukulawula okwengeziwe.
I-API entsha ebizwa I-AVCaptureDevice izonikeza onjiniyela amandla okufaka izilungiselelo ezilandelayo ezinhlelweni zabo zokusebenza: ukuzwela (ISO), isikhathi sokuchayeka, ibhalansi emhlophe, ukugxila, nesinxephezelo sokuchayeka. Ngenxa yezizathu zokuklama, imbobo ayikwazi ukulungiswa, njengoba igxilile ku-iPhone - njengakuningi lamanye amafoni.
Ukuzwela (okubuye kwaziwe ngokuthi yi-ISO) kubhekisela ekutheni inzwa yekhamera izoyibona ngokuzwela kangakanani imisebe yokukhanya yesigameko. Ngenxa ye-ISO ephakeme, singakwazi ukuthatha izithombe ezimeni ezingezinhle zokukhanya, kodwa ngakolunye uhlangothi, kufanele sicabangele ngomsindo okhulayo wesithombe. Okunye kwalokhu kulungiselelwa ukukhulisa isikhathi sokuchayeka, okuvumela ukukhanya okwengeziwe ukuthi kushaye inzwa. Okubi kwalokhu kulungiselelwa ingozi yokufiphala (isikhathi esiphezulu kunzima "ukusigcina"). Ibhalansi emhlophe ikhombisa izinga lokushisa lombala, okungukuthi ukuthi isithombe sonke sithambekele kanjani kokuluhlaza okwesibhakabhaka noma okuphuzi nokuluhlaza noma okubomvu). Ngokulungisa ukuchayeka, idivayisi ingakwazisa ukuthi ibala ngokungalungile ukukhanya kwesigcawu, futhi izobhekana nakho ngokuzenzakalela.
Imibhalo ye-API entsha iphinde ikhulume ngokuthi kungenzeka yini lokho okubizwa ngokuthi kubakaki, okuwukuthwebula okuzenzakalelayo kwezithombe ezimbalwa ngesikhathi esisodwa ngezilungiselelo zokuchayeka ezihlukene. Lokhu kusetshenziswa ezimweni ezinzima zokukhanyisa, lapho kunethuba eliphezulu lokuchayeka okubi, ngakho-ke kungcono ukuthatha, isibonelo, izithombe ezintathu bese ukhetha okungcono kakhulu. Isebenzisa futhi ubakaki ezithombeni ze-HDR, abasebenzisi be-iPhone asebeyazi kakade kuhlelo lokusebenza olwakhelwe ngaphakathi.
Ukusetha ukuchayeka sekuvele kungenzeka - ezinhlelweni zezinkampani zangaphandle - kodwa inketho yokusetha isikhathi sokuchayeka ekugcineni izokwenza kube nokwenzeka ukuthatha izithombe zesibhakabhaka sasebusuku noma izigcawu zasebusuku ngokujwayelekile nge-iPhone ku-tripod. Kuhle kakhulu! :-)
