Duab ua si ib qho tseem ceeb hauv cov ntawv xov xwm. Yog tias siv kom zoo, tsis yog tuaj yeem tsim kom zoo nkauj rau qhov tsim, nce neeg txoj kev nyiam nyeem ntawv, tab sis kuj ua tiav kev sib tw. Cov duab ntawm cov duab ua ntej luam tau ncaj qha rau cov nyhuv tom qab luam ntawv. Yog li ntawd, los ntawm kev xyaum ua xyoo, peb tau tsim ib co kev tshawb nrhiav txog kev ua duab.
Ua ntej luam daim duab, koj yuav tsum xub saib nws. Rau qhov zoo ntawm daim duab, nws yuav tsum tau ua nyob rau hauv lub hlwb, uas yog, seb qhov tau kis ntawm daim duab yog ntau heev los yog tsis txaus, thiab nws tsis tas yuav mus rau network, yog li ntawd daim duab yuav tsum tau ua tiav thaum lub sij hawm kev luam txheej txheem, vim hais tias daim duab tiav thaum lub sijhawm sojntsuam. Cov theem ntawm kev poob yog qhov tsawg kawg nkaus.
Daim duab no yog luam tawm xim. Yog tias nws yog ib qho duab grayscale, nws yuav zoo dua los siv lub xim liab. Grayscale duab tom ntawm xim yog ntau dua li tus grayscale duab scanned ncaj qha, tshwj xeeb tshaj yog rau cov xim nrog saturation ntawm 70% los yog ntau tshaj. Muaj ib qho kev xaiv "dash" nyob rau ntawm qhov chaw tiav qhov chaw nres tsheb ntawm linocolorelite. Yog tias nws yog ib daim luam, koj yuav tsum xaiv qhov nqi ntawm no. Ntau dua qhov kev luam ntawv, qhov loj dua cov duab yuav tsum tau xaiv. Ntxiv mus, 6 kev xaiv xws li "xim calibration" tuaj yeem raug xaiv ua lub neej ua ke, thiab xaiv tau raws li koj tus kheej. Qhov "Colour Assistant" nyob rau hauv "Calibration" yog lub cuab tam siv tau. Xaiv ib txoj kev sib txawv ntawm daim duab, lossis txiav txim siab xaiv tus nqi. Kho cov ntaub ntawv thaum lub sij hawm cov duab kev soj ntsuam yuav khaws cov txheej ntau thiab cov ntsiab lus.
Nyob rau hauv cov duab photoshop, peb yuav tsum xub txiav txim seb qhov dub thiab dawb teb thiab grey tshuav ntawm daim duab. Ob yam no tseem ceeb heev thiab tsim nyog. Kev txiav txim siab ntawm qhov dub thiab dawb teb tsis yog tib yam raws li kev xav tau luam tawm ntau. Tab sis tus txheej txheem yog hais tias dub teb tsis tau puas. Txawm li cas los xij, yuav kom paub meej cov duab hauv daim duab tom qab luam ntawv, nws yog ib qhov ua tau los xav txog ib qho chaw me me ntawm net los yog paste, tab sis nws yuav tsum tsis yog thaj tsam loj. Yog hais tias daim duab yog distorted, peb tuaj yeem kho nws cov xim los ntawm grey tshuav, tab sis qhov txho grey cuam tshuam xim ntawm tag nrho cov duab, yog li nws yuav tsum yog thaum siv. Kev pom ntawm grey tshuav nyiaj li cas tau muaj li nram qab no, uas yog, qis tshaj 20% los yog tshaj saud 80%, tus nqi ntawm tus cmy yeej sib npaug; nyob rau hauv nruab nrab tus nqi, tus nqi ntawm kuv yeej yog tib yam, tab sis tus nqi ntawm c yog 10% mus rau 15% ntau dua li tus nqi ntawm kuv.
Nyob hauv cov sijhawm ua haujlwm, cov dluab ntawm grayscale yuav tsum yoojyim. Muaj ob txoj hauv kev hloov xim duab rau hauv cov duab grayscale: ncaj qha mus hloov lawv nrog cov "hom" ua haujlwm; los yog hloov cov duab tha xim ua hom (lab) ua ntej, ces rho tawm "ib qho" thiab "b channel", thiab thaum kawg hloov cov duab rau hauv thiab "Grayscale". Hauv chroma (lab) hom kev hloov ua ke, lub luminance l channel khaws ntau txheej kev hloov, yog li cov nyhuv yuav zoo dua. Tom qab daim duab grayscale tas rau hauv daim dub thiab dawb, nws yuav tsum tau them nyiaj rau cov duab hauv. Lub suab nrov yuav tsum tau qhib. Txwv tsis pub, daim duab yuav muaj qhov xav tsis zoo, tsis meej thiab tsis meej, thiab qhov sib txawv hauv nruab nrab cov laus yuav nce, uas yuav ua kom zoo dua. Qhov teeb meem no.
Nyob hauv tus txheej txheem ntawm kev siv Photoshop los tsim cov duab, tsis txhob cia cov duab tig ib ncig ntawm ob hom. Vim hais tias txhua zaus ib qho kev hloov dua siab tshiab, ib feem ntawm daim duab yuavtsum tau poob. Thaum hloov cov rgb hom dluab hauv cmyk hom dluab, cov xim tsis sib cais yuav ua si lub luag haujlwm tseem ceeb hauv cov nyhuv ntawm cov duab hloov dua siab tshiab. Qhov kev hloov ntawm cov xim tsis sib cais yuav zoo heev rau qhov kev hloov ntawm daim duab. Cov duab photoshop duab ua software muaj peev xwm los tswj cov xim tsis sib cais. Uas yog hais tias, thaum nws yog tsim nyog yuav hloov cov duab ua nyob rau hauv rgb hom rau hauv lub hom cmyk rau cov zis, qhov kev hloov ntawm cov xim sib cais muaj peev xwm muab tau yeem hauv daim duab thaum hloov txheej txheem. Cov xim poob thaum lub hom hloov.
Yog hais tias rgb hom duab hloov dua siab tshiab rau cmyk hom, ib theem nrab yog ntxiv rau cov kauj ruam ua haujlwm, uas yog, thawj zaug hloov mus rau hom kev ua lag luam. Qhov kev tshawb fawb no muaj peb txoj kev, qhov l yog lub teeb ci, uas tswj cov ci ci thiab qhov sib txawv ntawm daim duab, thiab cov channel muaj xim los ntawm ntsuab ntsuab (tsis tshua pom ci ntsa iab) los txho (nruab nrab ci ntsa iab) high brightness tus nqi). Cov channel b muaj cov xim xws li xim ntsuab xiav (luminance tus nqi qis) los grey rau focal daj (siab luminance tus nqi).
Lub cim (lab) zoo ib yam li rgb hom, thiab cov xim ntawm cov xim ua kom muaj xim zoo nkauj. Tsuas yog tus nqi ntawm lub luminance channel cuam tshuam rau lub teeb thiab tsaus nti variations ntawm cov xim. Qhov kev ua hom (lab) tau xav txog ntawm kev ua ob hom ntawm rgb hom ntxiv rau ib qho kev sib txuas ntawm txoj kab. Lub cim (lab) hom yog kev ywj pheej thiab yuav siv los kho cov duab (nrog rau cov dluab grayscale) thiab ceev ceev raws li hom rgb, ob peb lub sij hawm sai tshaj qhov ntsuas cmyk. Qhov kev tshawb nrhiav (lab) yuav ua kom paub tseeb tias tsis muaj qhov xim poob hauv cov xim cmxij thaum ua xim hom hloov dua siab tshiab.
Zauv cov dluab hauv ntau hom yuav muaj teebmeem txawv. Zoo li kev ua hom (lab), nws yuav pab tau kom qhov sib txawv ntawm qhov duab, tab sis qhov tsis txaus siab tsis loj heev, txwv tsis pub cov duab yuav raug distorted. Rgb yog qhov zoo tshaj plaws rau kev ua cov duab, muab cov duab nrog saturation thiab ci ntsa iab, cov qib kev kawm thiab lwm yam kev ua haujlwm zoo heev, tshwj xeeb tshaj yog zoo ntawm kev kho neeg lub ntsej muag xim, tsis ua teeb meem los yog poob qib. Tsuas yog tag nrho cov duab yog hloov dua siab tshiab rau cmyk hom ua ntej luam ntawv, yog li muaj qhov kom zoo dua hauv kev kho cov duab hauv cmyk hom. Nyob rau hauv hom no, kho cov xim los ntawm cov channel yuav tiv thaiv tau cov duab los ntawm muab xim nrum, uas yog tseem yooj yim rau kev txiav txim siab dub thiab dawb teb.
Cov duab sib txawv yuav tsum tau ua cov txuj ci sib txawv. Cov duab xws li Suav cov duab yuav tsum ua ncaj ncees rau thawj zaj duab xis, thiab cov xim tsis tuaj yeem hloov vim cov nyhuv yog qhov zoo. Cov duab xws li comics thiab calligraphy yuav muab suav nrog cov bitmaps kom paub tseeb tias cov ntsiab lus tsis poob. Qhov no yog qhov tseeb thiab daim duab muaj peev xwm me, uas yuav ua rau kom ceev ceev ntawm cov plaub hau.
Tsis tas li ntawd, muaj ntau yam tseem ceeb hauv cov duab hauv Photoshop "Image One One adjustment", xws li "Brightness / Contrast", "Hawj txawm / Saturation", "Yeem Xim", thiab lwm yam Nyob hauv cov haujlwm tseeb, yuav tau zoo heev. nyhuv.
