Yog li, thaum lub sijhawm, nws yuav tsum raug sau tseg tias qhov feem pua ntawm cov feem ntawm txhua cov xim version yuav nce raws li, qhov tshwj xeeb tshaj yog nce ntawm ntsuab version thiab dub version. Nws yuav loj zog, tiam sis tus qauv ntsuab yuav tsum raug tswj hauv qab 30%. Cov dub version yuav tsum tsuas pom hauv nruab nrab thiab tsaus nti, thiab nws yuav tsum tsis txhob siab dhau.
Thaum cov ntawv sau tiav, muaj qee qhov sib txawv rau cov neeg ntawm cov tawv nqaij txawv. Peb yuav qhia lawv tawm hauv qab no.
Cov haiv neeg daj

Cov lus hauv qab no qhia qhov feem pua ntawm qhov chaw nyob ntawm txhua pawg ntawm pawg neeg:
C M Y A
Cov haiv neeg daj 15 45 50 0
Dawb haiv neeg 15 45 45 0
Dub haiv neeg 45 50 50 35
Nyob hauv tus txheej txheem ntawm kev ua tus ua cim tseem ceeb, tus tseem ntsiab raws li lub teeb pom kev zoo, qhov chaw uas qhov feem pua ntawm magenta dot siab tshaj 50% yuav tsum tsis txhob loj heev, txwv tsis pub lub cim yuav liab los yog tsaus, thiab qhov no yuav tsum raug txo kom tsawg tag nrho ntawm daim tawv nqaij ntawm thaj tsam ib nrab. Tsawg dua 1/3 tsim nyog, yog tias nws muaj tshaj, nws yuav tsum tau ci, tshwj rau cov duab nrog rau kev kho tshwj xeeb lub teeb.
Qhov kev ua tiav ntawm qhov ua cim tseem yog qhov tseem ceeb. Txawv ntawm txoj kev ua txawv yog txawv. Feem ntau, yuav tsum ua raws li cov hauv paus ntsiab lus thiaj li yuav ua rau daim tawv nqaij zoo thiab du du, qhov tawv nqaij tsis zoo thiab qhov zoo li tsis muaj zog; thiaj li ua rau tus xeeb ceem muaj kev cuam tshuam nrog peb sab, nws yog qhov tsim nyog yuav tsum hla qhov contour thiab qhov tseem ceeb. Yog li, yog tias tus cwj pwm tau ua tiav hauv PHOTOSHOP, qhov ntaus nqi yuav muab tau loj dua thaum tsim USM ntse. Thaum twg cov tawv nqaij ntawm tus neeg yog flawed, nws yog ib qho ua tau los ua ib co softening kho rau daim tawv nqaij. Thaum lub sij hawm kho txoj kev kho, nws tseem ceeb yuav tsum tau them nqi rau qhov hloov ntawm daim tawv nqaij txhua lub sij hawm kom tsis txhob muaj kev dhia ntawm lub suab lus. Nyob rau hauv tus txheej txheem ntawm kev xa thiab duab ua, qhov kev daws teeb meem thiab cov ntsiab lus ntawm cov xim sib txawv hauv daim ntawv yuav tsum raug ua tiav, uas yuav ua tiav cov txiaj ntsig zoo. Qhov sib txawv yog qhov tseeb, qhov qhib yog qhib, uas muaj ib lub cwj pwm ntawm qhov ntse ntawm daim duab.
Muaj ntau hom ntawv cob qhia. Peb tsuas yog sau ib phau ntawv me me rau cov ntaub ntawv luam tawm xwb.
