Raws li iPhone 12Pro series tshwj xeeb tshwj xeeb, Apple tau qhia txog qhov tshwj xeeb no ua nws qhov muag tseem ceeb ntawm lub caij nplooj zeeg cov khoom lag luam tshiab.

Tom qab ntawd dab tsi yog hom ntawv RAW.

RAW hom ntawv yog "RAW Image Format", uas txhais tau tias "tsis ua tiav".Cov duab kaw hauv RAW hom ntawv yog cov ntaub ntawv nyoos ntawm lub teeb liab teeb liab ntes los ntawm cov duab sensor thiab hloov mus rau hauv cov teeb liab digital.

Yav dhau los, peb coj JPEG hom, ces yuav cia li compressed thiab ua tiav rau hauv cov ntaub ntawv compact rau cia.Nyob rau hauv tus txheej txheem ntawm encoding thiab compression, thawj cov ntaub ntawv ntawm cov duab, xws li dawb tshuav nyiaj li cas, rhiab heev, shutter ceev thiab lwm yam ntaub ntawv, yog tsau rau tej ntaub ntawv.

Yog tias peb tsis txaus siab rau daim duab zoo li tsaus nti lossis ci dhau.

Thaum lub sijhawm hloov kho, daim duab zoo ntawm JPEG hom duab yuav raug degraded.Cov yam ntxwv ib txwm yog nce suab nrov thiab xim gradation.

Hom ntawv RAW tuaj yeem sau cov ntaub ntawv qub ntawm daim duab, tab sis nws tsuas yog sib npaug rau qhov taw tes thauj tog rau nkoj.Piv txwv li, nws zoo li phau ntawv, txhua yam ntawm cov ntaub ntawv nyoos tuaj yeem hloov kho ntawm qhov xav tau nyob rau hauv qee qhov ntawm nplooj ntawv tus lej, thiab cov duab zoo yuav tsis poob.JPEG hom ntawv zoo li ib daim ntawv, uas yog txwv ntawm "ib nplooj ntawv" thaum hloov kho, thiab kev ua haujlwm tsawg.

Qhov txawv ntawm ProRAW thiab RAW duab yog dab tsi?

ProRAW tso cai rau cov neeg nyiam kev yees duab thaij duab hauv RAW hom lossis siv Apple lub khoos phis tawj thev naus laus zis.Nws tuaj yeem muab ntau txoj haujlwm ntawm ntau cov duab ua haujlwm thiab suav nrog kev yees duab, xws li Deep Fusion thiab ntse HDR, ua ke nrog qhov tob thiab latitude ntawm RAW hom.

Txhawm rau ua tiav txoj haujlwm no, Apple tau tsim lub kav dej tshiab los ua ke ntau cov ntaub ntawv ua tiav los ntawm CPU, GPU, ISP thiab NPU rau hauv cov ntaub ntawv duab tob tshiab.Tab sis tej yam xws li sharpening, white balance, thiab tone mapping ua cov duab tsis es tsis txhob raug synthesized ncaj qha rau hauv daim duab.Ua li no, cov neeg siv tuaj yeem tsim kho cov xim, cov ntsiab lus, thiab ntau yam dynamic.

Hauv Cov ntsiab lus: Piv nrog RAW cov ntaub ntawv raug tua los ntawm lwm tus software, ProRAW ntxiv kev suav yees duab thev naus laus zis.Hauv txoj kev xav, nws yuav tau txais txiaj ntsig zoo dua, tawm hauv qhov chaw ua si ntau dua rau cov neeg tsim khoom.
