Peb pom ib yam dab tsi uas peb xav tias yuav ua kom muaj duab zoo nkauj, nplawm tawm cov koob yees duab thiab tom qab ntawd, tias qhov koob yees duab zoo tshaj plaws yog underexposed? Yog tias koj muaj Photoshop muaj ntau txoj kev kho sai rau koj. Qhov zoo tshaj plaws rau txhua yam koj tsis tas yuav yog ib daim ntawv pov thawj Photoshop Wizard los ua kom pom tseeb. Hauv qhov tseeb, "Photoshop Wizards" tau siv cov tswv yim no ua ntej lawv tau txais cov Photoshop Wizard robes.
Rau qhov nruab nrab neeg saib "txhim kho" uas yog Family BBQ Diam duab heev, nws tag nrho los rau hauv qhov tsis muaj dab tsi ntau tshaj qhov uas paub qhov chaw zoo li cas.
Nyob rau hauv no "Yuav ua li cas ..." peb yuav siv plaub hom kev kawm los mus nrog ib tus duab overexposed. Lawv yog:
- Yog kuaj tau nrog cov Ntawv Tso Cai.
- Siv Brightness thiab Contrast
- Nkag siab txog kev nyeem cov Histogram hauv qib.
- Siv Kev Tawm Ntxhais Layers thiab Blend modes
Cia peb pib.

Txheej Txheem 1: Yuav Ua Li Cas Tso Tseg Cov Ntawv Cuam Tshuam Los Ua Txhaum Cai
Nws yog lub caij nplooj zeeg yav tsaus ntuj thiab sawv ntawm lub pej thuam ntawm Goosepimple Lake Kuv nyuam qhuav tau muab ib daim duab ntawm qhov chaw zoo nkauj tso tawm ua ntej kuv, xav txog kuv txoj kev xav mus pom tus yees duab tsis muaj dab tsi.
Ib qho kev daws teeb meem yog siv cov Khoom Phom Tawm tuaj ntawm Image> Teb> Raug. Txawm hais tias Dialog lub thawv yuav pom ib qho me ntsis tsis meej nws yeej npog tawm ntawm peb lub ntsiab ntawm daim duab kho: White Point, Black Point, Midtones, los yog Gamma. Hauv lub thawv ntawv no lawv yog:
- Raug: Txhim kho cov ntsiab lus (White Point) thiab tsis quav ntsej txhua yam.
- Mhoob : Kho cov duab ntxoov ntxoo (Dub Point) thiab tsis lees paub txhua tsav txhua yam.
- Gamma Correction: Kho cov Midtones thiab ignores txhua tsav txhua yam.
Qhov koj tsis ua yog zawm tus slider. Xwb, koj siv ib lub eyedroppers -Txhua tus, Midtone, Dawb-rau "qauv" xim. Los ntawm qhov kuv txhais tau tias tus eyedropper yuav hloov tag nrho cov highlights, Midtones, los yog ntxoov ntxoo rau lub pixel koj nyem rau.
Hauv daim duab no, kuv tau xaiv tus White eyedropper vim, ua underexposed, daim duab tsaus thiab tsis muaj cov ntsiab lus tseem ceeb. Kuv ces clicked rau ntawm huab huab tom qab ntawm treeline,
Yog li cas tus eyedropper ua haujlwm li cas? Thaum koj nyem rau ntawm pixel dawb, nyob rau hauv cov ntsiab lus dav dav, tus eyedropper zoo li 5 pixels, pom qhov nruab nrab dawb tus nqi ntawm cov pixels, thiab cov teeb meem uas yog lub hauv paus rau dawb nyob hauv daim duab.
Yog tias koj siv cov txheej txheem no, tsis txhob saib pixel dawb pixel. Nrhiav ib yam dab tsi, zoo li qhov huab, uas yog "dawb dawb".
Raug kuj tseem muaj raws li Kev Txheej Txheem uas cia koj "tweak" qhov chaw uas tsis nyiam cov zaub mov.

Txheej Txheem 2: Yuav Siv Cov Kev Cuam Tshuam thiab Kev Teeb Meem ntawm Contrast
Yog hais tias tus duab tsaus tsaus tej zaum nws tsuas xav tau ci ntsa iab. Qhov no yog qhov tsuas yog qhov yuav tsum tau ua thiab, raws li koj yuav pom, uas tej zaum yuav yog qhov yuam kev. Kom pib rau kuv qhib Image> Teb> Brightness / Contrast .
Lub thawv ntawv qhib uas qhib muaj ob txoj kab lus: ib qho rau Brightness thiab lwm yam kev Contrast . Muaj kuj yog pib lub pob. Nws yuav tsum raug zam rau vim qhov tshwm sim yog inconsistent. Xwb, siv koj ob lub qhov muag los txiav txim seb qhov txiaj ntsig zoo li cas.
Yuav kom ci tau ib qho duab txav cov Brightness slider rau sab xis. Kom nws tsaus ntuj nti, txav mus rau ntawm tus swb. Nyob rau hauv cov ntaub ntawv ntawm cov duab no, Kuv tsiv lub ci ntsa iab mus rau sab xis.
Thaum koj nce qhov ci ntsa iab, kuj ua tib zoo saib ntawm Contrast. Cov ob mus ua ke. Yog hais tias koj nce lub ci ci, sim txo qhov sib txawv rau coj tawm ib me ntsis ntau yam nyob rau hauv daim duab.
Brightness / Contrast kuj tseem muaj raws li Kev Txhim Kho Txheej Txhawb uas yuav ua rau koj "tweak" cov chaw tsis zoo rau cov ntawv qhia zaub mov.

Txheej Txheem 3: Yuav Siv Qhov Ntaus Li Cas
Qhov txheej txheem thib peb tau txais koj cia rau hauv cov nroj tsuag nrog pixels thiab txhais tes koj ob txoj kev ntawm ci ntsa iab txog tus duab.
Yuav pib tau rub tawm cov Theem Menyuam. Thaum lub thawv qhib qhov rooj koj yuav pom ib lub teeb, uas hu ua Histogram, thiab peb lub eyedroppers.
Ib cov histogram qhia koj tonal tis hauv daim duab. Ib qho zoo kawg nkaus histogram tsoo ib lub voj voos tsaj ntsej muag.Thaum cov duab no, daim duab yog shoved mus rau sab laug-lub Dub - thiab muaj zoo li tsis muaj dab tsi nyob nruab nrab ntawm qhov nruab nrab ntawm qhov nruab nrab ntawm tus zauv ntawm Sab Saum Nruab Nruag thiab Dawb rau ntawm txoj cai. Qhov no yog ib qho piv txwv ntawm ib daim duab keebkwm (Underexposure histogram).
Muaj ob txoj kev ci ci rau cov duab.
Thawj yog kom luag cov Dawb slider mus rau sab laug qhov muaj zoo li ib co tones ntawm cov histogram. Thaum koj txav lub dawb slider lub midtone slider kuj tsiv mus rau sab laug. Yog li cas mus rau? Ntxiv dua thiab, nyob hauv cov ntsiab lus yooj yim, koj tab tom qhia Photoshop tias tag nrho cov pixels ntawm cov dawb thiab nruab nrab-126 txog 255-tam sim no muaj nqi ntawm 255 uas tam sim no lightens cov teeb meem pixels. Qhov tshwm sim yog ib qho duab zoo zog.
Lwm txoj kev yog nias qhov khawm Xaiv nyob rau hauv lub Thawv Phaj Siab. Qhov no yuav pib qhib xim xim kho lus dialog box. Cov kev xaiv plaub cuam tshuam rau cov duab sib txawv thiab, thaum koj xaiv ib qho kev xaiv, cov histogram tseem yuav hloov. Hauv qhov no, Kuv xaiv Nrhiav Dark & Light Colours uas tau tawm ntawm qhov tseeb hauv daim duab.
Qib no kuj muaj raws li Kev Kho Txheej Txhawb uas qhib cia koj "tweak" qhov chaw tsis zoo rau cov ntawv qhia zaub mov. Cov Kev Txhim Kho Dua Qub tsis muaj Xim Kho Cov Xaiv.

Txheej Txheem 4: Siv Kev Txheej Txheem Thiab Cov Qauv Uas Hloov
Koj tuaj yeem pom cov kev cob qhia peb zaug uas tau hais los ntawm kev siv Kev Txhim Kho. Xav txog qhov Txheej Txheej li kev muab koj lub peev xwm los "tweak" koj qhov chaw yog tias tej yam tsis zoo.
Yuav kom qhov point no nyob rau hauv no "Yuav ua li cas" txhua yam uas koj tau ua yog yeej tseem raug cawm dim. Muaj tsis muaj rov qab yog tias koj tsis tau npaj siab rov qab rau daim duab rau nws lub xeev qub. Peb hom kev kawm dhau los no suav tias yog "kev puas tsuaj" rau txhua qhov kev hloov uas koj ua yog qhov ruaj khov.
Nco ntsoov tias Histogram los ntawm cov txheej txheem dhau los? Daim ntawv histogram zoo yog xim tawv nqaij. Siv ib qho ntawm peb hom kev kawm nthuav tawm, rov qhib dua thiab koj yuav pom ib qho histogram ntau heev. Nws zoo li muaj qhov nyob rau hauv nws los yog raws li kuv nyiam hais tias, "Nws zoo li ib lub laj kab tsib."
Cov qhov sawv cev duab cov duab uas tau muab pov tseg tawm thiab yeej tsis raug muab rov qab. Txhim kho cov duab thiab cov histogram yuav kab hauv kab txawm tias cov duab yuav pom zoo. Ntawd yog ib rooj plaub ntawm kev teeb tsa kev puas tsuaj.
Ib qho Kev Txheej Txheej Txheem raug hu ua "Non Destructive" vim hais tias qhov kev hloov yog siv los ntawm ib txheej tsis ncaj nraim rau daim duab. Yog hais tias koj tsis xav tau lub lwv tawm nws thiab nws cov nyhuv ntawm cov duab pib yog muab tshem tawm. Xav hloov chaw? Nias lub hau lus thiab hloov qhov kev hloov. Nws yog qhov yooj yim.
Hauv qhov no, kuv nias lub hau lus khawm rau hauv qab ntawm cov khaubncaws sab nraud povtseg thiab xaiv ntau ntau ntawm qhov tshwm sim popup tuaj. Ib qho Txheej Txheem tshiab tshwm saum toj kawg nkaus. Zoo li cov Histogram tshwm nyob rau hauv cov khoom vaj huam sib luag thiab kuv tuaj yeem kho Qhov Dawb taw los ntawm txav cov slider los yog txhaj rau ntawm ib qho dawb pixel hauv daim duab los teeb lub tshav dawb. Hauv qhov no, kuv yuav ua tsis tau. Xwb, Kuv xaiv qhov Screen Blend Mode thiab, thaum kuv tso tus nas, cov duab ci tuaj thiab ntau nthuav dav. Dab tsi tshwm sim?
Blend Modes yeej zoo siv qee cov kev ua lej ntau rau cov pixels hauv ib daim duab. Nrog Screen, txhua yam ntawm txheej uas dub ntshiab yuav ploj los ntawm saib. Yuav ua li cas uas ua haujlwm, nyob rau hauv ntau broad lus, yog tag nrho cov "ci ntsa iab" qhov tseem ceeb hauv daim duab thiab cov txiaj ntsig siv rau tag nrho cov duab pixels hauv daim duab. Txhua yam uas ntshiab dawb yuav nyob twj ywm tsis hloov, thiab txhua yam ntxoov ntxoo ntawm grey ntawm dawb huv thiab dawb huv dawb yuav dhau los ua ke.
Rau cov ntsiab lus lawm, koj tuaj yeem txhim kho cov duab ntau dua.
Duplicate tus txheej txheem ntawm kev hloov thiab tsis hloov hloov Hom, txo qhov txheej txheem ntawm Opacity tus nqi. Qhov no tsis yog "hu rov qab" qhov ci ntsa iab thiab coj mus nthuav dav ntxiv hauv daim duab.
