Adam Kos Txawm tias niaj hnub no, cov neeg siv tseem xav paub ntau ntxiv txog tus naj npawb ntawm megapixels uas muaj nyob hauv lub koob yees duab smartphone thaum tso tawm lub cim tshiab ntawm cov chaw tsim khoom muab ntau dua li nws cov txiaj ntsig. Tom qab tag nrho, nws tseem yog ib qho kev lag luam tawm los ntawm lawv, vim tias tus lej ntau dua tsuas yog zoo dua. Txawm li cas los xij, hmoov zoo, hauv cov khoom tshwj xeeb, lawv kuj feem ntau hais txog ib qho tseem ceeb ntxiv rau qhov zoo ntawm cov duab tshwm sim, thiab qhov ntawd yog qhov aperture.
Nws tuaj yeem hais tias tus naj npawb ntawm megapixels yog qhov kawg uas yuav tsum txaus siab rau koj ntawm cov yam ntxwv ntawm lub koob yees duab smartphone. Tab sis cov lej zoo li zoo, thiab nthuav tawm zoo heev, uas nws nyuaj rau mus tom qab lwm cov ntsiab lus. Qhov loj tshaj plaws yog qhov loj ntawm lub sensor thiab tus kheej pixels nyob rau hauv kev twb kev txuas nrog lub aperture. Tus naj npawb ntawm MPx tsuas yog ua rau kev txiav txim siab nyob rau hauv cov ntaub ntawv ntawm kev luam ntawv loj lossis ntse zooming. Qhov no yog vim hais tias lub koob yees duab smartphone aperture tswj ntau qhov ntse, raug, ci ntsa iab thiab ua kom pom tseeb.

Dab tsi yog aperture?
Qhov me me f-number, qhov dav qhov aperture. Qhov dav ntawm qhov aperture, lub teeb tuaj ntau dua. Yog tias koj lub smartphone tsis muaj qhov dav txaus aperture, koj yuav xaus nrog cov duab tsis pom thiab / lossis nrov nrov. Qhov no tuaj yeem pab tau los ntawm kev siv lub kaw lus qeeb qeeb lossis teeb tsa ISO siab dua, tab sis cov chaw no feem ntau yog siv rau ntawm DSLRs, thiab piv txwv li lub koob yees duab hauv iOS no tsis tso cai rau cov chaw no, txawm hais tias koj tuaj yeem rub tawm cov npe muaj tseeb ntawm cov npe. App Store ua li ntawd.
Yog li qhov kom zoo dua ntawm qhov dav apertures yog tias koj tsis tas yuav kho qhov ceev ceev lossis ISO qhov twg lub teeb qis dua, uas txhais tau tias koj lub koob yees duab yuav hloov tau yooj yim dua hauv cov teeb pom kev sib txawv. Nws yog qhov tseeb, txawm li cas los xij, qhov no yog raws nraim li cas ntau hom hmo ntuj tab tom sim daws. Nws yog ib qho nyuaj rau kev thaij duab ntawm tib neeg thiab kev txav mus los rau lub sijhawm ntev, tsis tas li ntawd, koj tuaj yeem co thiab ua kom pom qhov muag tsis pom. Ib qho ISO siab dua, ntawm qhov tod tes, tuaj yeem ua rau lub suab nrov vim tias koj tab tom ua kom lub sensor ntau dua rau lub teeb uas koj tsis tau txais, ua rau muaj kev cuam tshuam digital.
Qhov loj ntawm qhov aperture kuj yog lub luag haujlwm rau qhov tob ntawm qhov chaw, uas ua rau ntau dua lossis tsawg dua bokeh, piv txwv li kev cais ntawm qhov kev kawm los ntawm keeb kwm yav dhau. Qhov me me ntawm qhov aperture, qhov ntau cov ntsiab lus raug cais tawm ntawm keeb kwm yav dhau. Nws yog qhov zoo kom pom nrog iPhone 13 Pro thiab nws lub kaum sab xis dav thaum koj sim thaij duab ze ze thiab tua macro. Bokeh thiab aperture nws tus kheej feem ntau cuam tshuam nrog Portrait hom hauv qhov no. Txawm li cas los xij, nws ua haujlwm hauv software thiab tuaj yeem pom qhov yuam kev. Txawm li cas los xij, yog tias koj kho nws, koj yuav pom qhov sib txawv.

Siab dua MPx thiab aperture nyhuv
Kua tau kho qhov kev daws teeb meem ntawm nws cov koob yees duab ntawm 12 MPx, txawm hais tias nrog iPhone 14 lawv xav tias yuav tuaj nrog nce mus rau 48 MPx, tsawg kawg rau cov qauv Pro thiab lawv lub koob yees duab dav. Txawm li cas los xij, nws yuav tsis mob yog tias nws tuaj yeem ua raws li tus lej f-tus lej zoo tagnrho, uas yog qhov txias tiag tiag ƒ/1,5 ntawm tus qauv Pro tam sim no. Tab sis sai li sai tau thaum nws loj hlob, qhov nce hauv MPx yog qhov tsis muaj txiaj ntsig, yog tias lub tuam txhab tsis tau piav qhia nws cov kauj ruam rau peb, uas nws ua tau zoo dua. Paradoxically, peb tuaj yeem xaus nrog ntau MPx nrog tus lej aperture ntau dua nyob rau hauv lub cim tshiab ntawm iPhone siv cov duab tsis zoo dua li MPx tsawg dua nrog tus lej aperture qis dua hauv cov neeg laus.
Kuv ntxub nws thaum lub keeb kwm yav dhau yog xoob hauv cov duab, nws qias neeg! Tag nrho cov duab yuav tsum zoo nkauj ntse thiab tag nrho cov ntsiab lus. Cia siab tias iPhones yuav los ze rau hnub ntawd. Txog tam sim no, nws tsuas yog lub koob yees duab dummy, uas tseem nyob deb dhau ntawm Android kev sib tw!
Qhov no yog qhov tsis muaj tseeb. Tom qab tag nrho, yog vim li cas muaj, piv txwv li, ib tug tag nrho phau ntawv hom rau DSLRs, qhov twg koj yuav teem lub dawb huv trinity, i.e. aperture, lub sij hawm thiab ISO. Ua tsaug rau qhov no, kuv tuaj yeem tswj tau qhov tob ntawm qhov chaw, suab nrov, qhov ntse ntawm daim duab. Cov duab uas tsis tshua muaj qhov tob ntawm qhov chaw, piv txwv li qhov muag tsis pom tom qab, saib zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv uas keeb kwm yav dhau "luag" los ntawm optics thiab tsis software tom qab ua tiav, ib yam li cov ntaub ntawv nrog pidi lo ntsiab muag ntawm cov xov tooj ntawm tes. Vim tias qhov teeb meem nrog cov lo ntsiab muag me me no yog tias lawv ib txwm muaj qhov tob ntawm qhov chaw thiab nws yog qhov tsim nyog los pab nrog software. Thiab nws tsis muaj teeb meem yog tias nws yog iOS, Android lossis ib zaug nrov compact koob yees duab.
thiab rau qhov tseeb hais tias nws yog hais txog lub brightness ntawm lub lens thiab tsis yog lub aperture, lub xov tooj ntawm tes (raws li kuv paub) tsis muaj ib tug adjustable aperture, uas yog, nws tsuas yog tawm ntawm brightness.
Lub aperture ntawm lub lens yog txiav txim los ntawm tus tsim thiab yog qhov ua tau qis tshaj f-tus lej. Nrog cov xov tooj ntawm tes, tau kawg, lub aperture tuaj yeem hloov pauv, tab sis tsuas yog siv hluav taws xob, tsis yog tshuab, ib yam li cov ntaub ntawv, piv txwv li, nrog SLR lo ntsiab muag. Ntawm chav kawm, qhov zoo dua qhov aperture (piv txwv li qhov qis tshaj qhov qis tshaj tau aperture tus naj npawb), qhov zoo dua thiab kim dua lub lens. Tsuas yog muab rau koj ib lub tswv yim, ntawm Canon, ib qho ruaj 1,8 f / 3000 lo ntsiab muag raug nqi txog 1,4 CZK, 11.000 f / 1,2 lo ntsiab muag raug nqi txog 40 CZK, thiab XNUMX f / XNUMX lens nqi XNUMX. Tsis tas li ntawd, lub lens ci dua, qhov loj dua thiab hnyav dua, qhov ntau "iav" nws muaj
Ib qho kev daws teeb meem siab dua, piv txwv li MPx ntau dua, yog qhov tseem ceeb nyob rau hauv rooj plaub ntawm kev txiav tawm los ntawm daim duab, lossis lub npe hu ua digital zoom, uas yog qhov zoo ib yam. Hmoov tsis zoo, qhov no ua rau muaj teeb meem suab nrov nrog me me sensor chips. 12 MPx yog txaus txaus nyob rau hauv feem ntau.
Iphone yeej tsis rov. Slow down seem thiab tus nqi ntawd. Xiaomi, ntau pheej yig dua, siv cov duab zoo dua thiab qhov kev ua tau zoo yog lwm qhov. Lub iPhone yog overpriced qeeb shunt.
