Kev tshuaj ntsuam chaw rau grayscale keeb kwm
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Niaj hnub no, thaum cov xim thawj coj tau siv, nws yog ib qho uas tsimnyog tias tib neeg yuav hais txog kev luam cov grayscale keebkwm. Qhov tseeb, hauv cov phau ntawv tam sim no, cov ntawv xov xwm, cov ntawv xov xwm thiab tej tseem npau suav luam ntawv, grayscale luam tawm tseem muaj chaw.
Ntau tus neeg xav tias cov luam ntawm grayscale keeb kwm yog yooj yim dua li ntawm cov xim dawb. Qhov tseeb, nyob rau hauv tus txheej txheem ntawm kev luam, nws tsis yog ib qho yooj yim ua haujlwm kom muaj kev cuam tshuam cov artistic nyhuv ntawm grayscale phau ntawv thiab ua siab ntev restore cov ntawv sau.
Thaum luam cov grayscale keeb kwm, them nyiaj tshwj xeeb mloog rau cov style thiab sib piv ntawm photography. Ua ntej tshaj plaws, peb yuav tsum tuav lub teeb thiab tsaus sib txawv thiab qhov sib txawv ntawm cov duab ua ib qho zoo, thiab tom qab ntawd mam li nrog lub suab nrov ntawm lub ntsej muag, lub ntsej muag ntawm nruab nrab cov laus, thiab cov xim dub.
Cia wb mus saib ntawm qee qhov chaw rau kev sojntsuam ib daim duab grayscale.
1. Teem rau cov tiaj dawb
Qhov tseem ceeb yuav tsum yog qhov tseem ceeb, thiab cov nqi ntawm qhov siab tshaj plaws hauv qhov siab tshaj plaws hauv qhov xub thawj yuav raug teem rau 0, tiam sis qhov cheeb tsam ntawm qhov ntsuas 0 yuav tsum tsis yog loj heev. Qeb sub-highlight yuav raug teem ntawm 3% mus rau 5% ntawm qhov point. Nyob rau hauv no txoj kev, lub whiteness ntawm daim ntawv yuav tsum tau siv los txhim khu lub ci ci siab ntawm cov ntawv luam tawm, thiab cov nyhuv ntawm kev ci ntsa iab thiab brilliance yog tiav.
Qhov chaw ntawm lub tshav pob yog qhov tseem ceeb heev rau kev luam ntawm thawj. Yog hais tias cov dots loj dhau, qhov feem ntau siab ntawm cov ntawv luam tawm yuav yog grey thiab tsis kaj, ua rau tsis zoo txaus; Yog hais tias qhov chaw siab tsis tshua muaj siab loj heev (Mesh cheeb tsam yog loj dhau), Ua rau siab poob, coarse hais thiab lwm yam. Thaum koj pom lub tshav dav dawb, raws li tus yam ntxwv ntawm tus tseem ceeb, koj tuaj yeem xa mus rau cov ntsiab lus hauv qab no: (1) Rau qhov qub uas muaj qhov raug thiab qhov sib txawv ntawm qhov sib txawv, lub teeb siab tsis tshua muaj peev xwm muab teeb tsa ua ib qho meej meej. (2) Rau ntau tus neeg, qhov tseem ceeb heev, qhov tseem ceeb ntawm qhov tseem ceeb ntawm qhov ntsuas ntawm qhov yuav tsum tau teem rau ntawm 3% -5% thaum lub tshav pob dawb tau teeb tsa lub suab qis ntawm qhov kaj. (3) Rau hauv-kis, tuab-density keeb kwm, thaum lub teeb ci tsis tshua muaj siab ua raws li lub meej net, nws yuav tsum brighten lub nruab nrab thiab kaj lug rau kev txhawb lub ntsiab thiab nruab nrab-lub teeb theem.
2. Kev teeb tsa rau dub dub
Tsom siab rau theem tsaus nti. Feem ntau, qhov chaw dub yog qhov tsawg me thiab tsis tuaj yeem teem loj heev. Tsawg me me yuav ua rau cov duab grayed, thiab loj loj yuav ua rau theem tsaus. Feem ntau, cov nqi teev yog teev rau 95%. Thaum teem caij dub, nws yog ib qho tseem ceeb heev uas yuav tau xaiv qhov point. Sim xaiv qhov nruab nrab dub nruab nrab ntawm cov khoom dub thiab xyuas kom meej ntawm qhov chaw ntawm qhov teev nqis.
Nyob rau ntawm daim teb dub, nws yuav tsum tau muab sau tseg tias qee qhov tsaus nti ntawm qhov tsaus ntuj ntawm qhov tseem ceeb yog nyob rau hauv txoj hauv kev nrog ob sab dub, thiab qib tsis tuaj yeem qhib. Nyob rau lub sij hawm no, qhov tsaus ntuj ntws yog tob, thiab qhov dub yog qhov tob ntxiv. Nws yog ib qho yooj yim uas yuav ua rau kom tsaus ntuj ntawm cov ntawv luam tawm kom tsaus ntuj. Ntawm qhov tod tes, yog hais tias dub teb calibration yuav siv sij hawm mus rau hauv tus txheej txheem ntawm qhov dub-qhov dub, qhov tsaus ua ntawm qhov tsis tshua dub yog tsis txaus, thiab nws yog qhov nyuaj rau sib npaug ntawm ob. Ua li no, peb qhia ib txoj kev rau txhua tus neeg, koj xav sim: qhib lub teeb ci mus rau lub teeb nyob tom qab ntawm daim duab, thiab qee zaus cov duab tsaus nti thiab nruab nrab ntawm daim duab qhia tawm, siab ua tiav.
Tsis tas li ntawd, qhov kev xaiv ntawm qhov qhab nees yuav tsum tau txiav txim siab raws li qhov ntsuas, qhov sib txawv, thiab qhov sib txawv ntawm qhov tseem ceeb, thiab nws yog ib qho tseem ceeb uas yuav tsum xav txog seb lub cev ntawm daim duab ntawm lub cev yog qhov twg. Feem ntau, kom zoo tsim tau cov theem nruab nrab thiab tsaus ntuj, ib 5% nkhaus yuav siv los piav txog 5% thiab lub suab tsaus nti kom kaj 10%.
Nta, qee cov neeg nyob hauv txoj kev lag luam yog hais txog grayscale keebkwm. Thiaj li yuav ua rau cov ntawv luam muag zoo nyob hauv cov khaubncaws sab nraud povtseg thiab hnyav rau hauv plev npoo txheej, lawv xav siv ob lossis plaub xim rau daim ntawv grayscale keebkwm hauv cov phaj thaum pib ua haujlwm (hom qes siab kawg). Qhov tseem ceeb tshaj ntawm cov qauv ntawm txoj cai no yog qhov yuav tsum tau them sai sai rau qhov teeb meem ntawm qhov nruab nrab ntawm qhov nruab nrab ntawm grey. Qhov nruab nrab ntawm qhov nruab nrab grey tsis zoo, nws yuav ua rau txhua qhov xim ntawm daim duab, yog li thaum kho cov duab, koj yuav tsum tau them nyiaj rau qhov hloov ntawm cov xim plaub-xim. Nyob rau hauv tas li ntawd, nyob rau hauv no hom ntawm kev ua, qhov dub version txais lub pob txha laus skeleton. Yog tias C version 50%, cov duab theem nrab tsis txaus, thiab cov nyhuv stereoscopic tsis muaj zog. Nws yog zoo dua mus rau qhov chaw pib ntawm cov dub version rau Cov C version muaj ib qho kev teev me me ntawm 35% -40%, uas tuaj yeem ua rau theem nrab thiab tsaus tone qib thiab stereoscopic nyhuv ntawm daim duab.
Qhov tseeb, los luam tawm cov ntawv zoo, qhov tseem ceeb ntawm qhov tseem ceeb yog qhov tseem ceeb. Hauv qhov saum toj no peb tham txog qee qhov tsis muaj tus grayscale thawj calibration, tab sis, yog tias tsis muaj qhov zoo, yuav tsis muaj kev pov hwm zoo, vim li ntawd peb yuav tsum them nqi rau qhov tseem ceeb. Ua tib zoo soj ntsuam cov khoom xub thawj ua ntej cov khoom siv, thiab tom qab ntawd ces ua tus tswj cov txheej txheem luam ntawv kom ua tau zoo nkauj zoo nkauj.
