Nquag Nug Cov Lus Nug Txog Cov Duab Cov Ntaub Ntawv

Kuv puas yuav tsum tau tua txhua yam hauv RAW?

Thaum RAW muaj qhov zoo tshaj plaws thiab kev hloov kho yooj yim, nws tsis tas yuav tsim nyog rau txhua qhov xwm txheej. RAW yog qhov zoo tagnrho rau kev ua haujlwm, teeb pom kev zoo, lossis thaum xav tau kev tswj xyuas ntau tshaj plaws. JPEG tej zaum yuav txaus rau kev yees duab xws li yees duab, cov xwm txheej uas koj xav tau nrawm nrawm nrawm, muaj qhov txwv cia, lossis xav tau kev sib koom tam sim. Ntau tus kws tshaj lij siv RAW + JPEG kom muaj ob qho kev xaiv muaj.

Vim li cas kuv cov xim txawv thaum kuv muab cov duab hauv online?

Cov xim sib txawv hauv online tuaj yeem tshwm sim rau ntau qhov laj thawj: kev hloov xim tsis zoo (tsis hloov mus rau sRGB rau kev siv lub vev xaib), uas ploj lawm cov xim sib txawv, kev tswj hwm xim sib txawv ntawm qhov browser, sib txawv cov duab calibrations, thiab social media platforms ‘compression thiab ua. Txhawm rau txo cov teeb meem no, ib txwm hloov mus rau sRGB xim qhov chaw, embed xim profiles, siv software nrog kev tswj xim kom zoo, thiab saib koj cov duab ntawm ntau yam khoom ua ntej sib koom.

Dab tsi yog qhov txawv ntawm lossy thiab lossless compression?

Lossless compression txo cov ntaub ntawv loj yam tsis tau muab pov tseg cov duab cov ntaub ntawv, tso cai rau kev tsim kho zoo ntawm cov duab qub (piv txwv: PNG, TIFF nrog ZIP compression). Lossy compression tas li tso tseg qee cov duab cov ntaub ntawv kom ua tiav cov ntaub ntawv me me (piv txwv: JPEG, WebP hauv hom poob). Lossless yog qhov zoo tagnrho rau kev ua haujlwm cov ntaub ntawv thiab khaws cia, thaum poob yog tsim nyog rau kev xa khoom zaum kawg thaum cov ntaub ntawv loj. Qhov sib txawv tseem ceeb yog tias lossy compression tsis tuaj yeem thim rov qab kom rov qab tau cov ntaub ntawv qub.

Kuv puas yuav hloov kuv cov ntaub ntawv RAW rau DNG hom?

Hloov mus rau DNG muaj ntau yam txiaj ntsig: txhim kho kev sib raug zoo ntev ntev raws li tus qauv qhib, cov ntaub ntawv me me nrog kev poob qis, kos cov metadata uas tsis xav tau cov ntaub ntawv sidecar, thiab kev ua tau zoo hauv Adobe software. Txawm li cas los xij, muaj kev xav txog: kev hloov pauv yuav siv sij hawm, qee cov ntaub ntawv lub koob yees duab tshwj xeeb yuav ploj, thiab tsis yog txhua tus software txhawb nqa DNG. Ntau tus kws yees duab hloov mus rau DNG rau lub hom phiaj archival thaum khaws cov ntaub ntawv RAW qub li thaub qab.

Hom ntawv zoo tshaj plaws rau luam tawm kuv cov duab yog dab tsi?

Rau kev luam ntawv, TIFF feem ntau suav hais tias yog hom ntawv zoo tshaj plaws vim nws khaws tag nrho cov khoom zoo thiab txhawb nqa 16-ntsis xim qhov tob thiab ntau qhov chaw xim. Rau cov neeg siv khoom yees duab labs, JPEG zoo (90-100% zoo) feem ntau yog txaus thiab txais ntau dua. Thaum npaj cov ntaub ntawv luam tawm, siv Adobe RGB xim qhov chaw kom dav gamut, xyuas kom tsim nyog daws teeb meem (300 PPI yog tus qauv), thiab xyuas cov kev cai tshwj xeeb ntawm koj qhov kev pabcuam luam tawm raws li lawv yuav muaj hom kev nyiam lossis kev txwv.

Kuv yuav ua li cas optimize dluab rau kuv lub website yam tsis poob zoo?

Txhawm rau txhim kho cov duab hauv lub vev xaib thaum tswj xyuas qhov zoo: hloov cov duab mus rau qhov loj me uas xav tau (tsis txhob cia siab rau qhov browser scaling), siv JPEG ntawm 70-80% zoo rau cov duab, xav txog WebP hom rau cov browsers niaj hnub, siv PNG rau cov duab nrog cov ntawv lossis pob tshab, siv cov duab teb nrog ntau qhov ntau thiab tsawg, siv cov duab niaj hnub CDNs uas ua kom zoo dua rau cov duab hauv qab no. Cov cuab yeej zoo li ImageOptim, Squoosh, lossis ShortPixel tuaj yeem pab nrhiav qhov pom kev sib npaug ntawm qhov zoo thiab cov ntaub ntawv loj.

Dab tsi yog qhov txawv ntawm 8-ntsis thiab 16-ntsis duab?

Qhov tob me ntsis yog hais txog tus nqi ntawm cov ntaub ntawv xim khaws cia ib channel hauv ib daim duab. 8-ntsis cov duab khaws 256 qib ib channel (16.7 lab xim tau), thaum 16-ntsis dluab khaws 65,536 qib ib channel (trillions ntawm cov xim tau). Cov txiaj ntsig zoo ntawm 16-ntsis yog smoother gradients thiab ntau dua kho kom haum ua ntej pom banding lossis posterization tshwm sim. Siv 16-ntsis thaum hloov kho thiab rau cov ntaub ntawv tswv, tshwj xeeb tshaj yog thaum ua kev hloov pauv tseem ceeb rau kev nthuav tawm, xim, lossis lub suab. Rau kev xa khoom zaum kawg, 8-ntsis feem ntau yog txaus vim tias cov khoom siv feem ntau tsuas tuaj yeem pom 8-ntsis xim.

Kuv tuaj yeem khaws kuv cov duab zoo li cas rau ntau xyoo?

Rau kev khaws cia ntev ntev: khaws cov ntaub ntawv qub RAW / DNG thiab kho cov tswv (TIFF / PSD), siv ntau hom kev khaws cia (sab nraud drives, huab cia, archival optical media), siv lub tswv yim 3-2-1 thaub qab, khaws cov tsav tsheb hauv huab cua tswj ib puag ncig, tsis tu ncua tshawb xyuas cov ntaub ntawv kev ncaj ncees nrog checksums, txhua txhua xyoo siv 5D, qhib cov ntaub ntawv tshiab TIFF), embed cov ntaub ntawv metadata (txoj cai, cov ntsiab lus, cov lus piav qhia), tuav cov kab ke teev tseg, thiab sau koj lub koom haum cia rau yav tom ntej siv. Kev txheeb xyuas tsis tu ncua thiab kev tsiv teb tsaws yog qhov tseem ceeb vim tias txhua qhov chaw khaws cia cov xov xwm degrade dhau sijhawm.
