Tom qab thaum computers tshiab thiab graphics tau thawj qhia ntawm cov computer cov ntxaij vab tshaus, cov duab tsis ntsia tsis pom ib yam li crisp cov duab rau hnub no cov computers thiab cov khoom siv. Lawv tended mus nrhiav rather "chunky" vim lawv muaj cov duab bitmap. Txhua pixel hauv daim duab tau mapped rau ib ntawm 256 cov grays ... los yog tsawg dua. Qhov tseeb, nyob rau hauv cov hnub nyoog ntxov- xav tias 1984 txog rau 1988 - cov saib xyuas yuav qhia tau dub thiab dawb xwb. Yog li, txhua yam duab uas tau pom hauv computer screen mas, yeej tseem zoo, dub thiab dawb thiab muaj ib qho kev sib dhos ntawm kev sib tsoo.
Ob peb lub hlis dhau los peb tau qhia koj tias yuav ua li cas los tsim cov khoom plig uas siv los ntawm Phab Ntsa Street Journal . Hauv no "Yuav Ua Li Cas" peb tab tom yuav qhia koj txog lwm txoj hau kev uas tsim los ntawm tsim ib qho duab hauv Photoshop.
Yog hais tias koj tsis paub nrog lub sij hawm "halftone" nws yog ib qho txheej txheem luam ntawv uas siv cov dots ntawm number case ntawm qhov ntau thiab tsawg, cov ces kaum thiab nrawm rau simulate duab dub thiab dawb. Yog tias koj xav pom qhov no hauv qhov kev txiav txim, ua txhaum tawm ntawm lub khob nplaum thiab saib ib daim duab hauv koj cov ntawv xov xwm hauv zos.
Tus yuam sij rau tsim ib nrab hnub hauv Photoshop CC yog los ntawm kev hloov ib qho duab rau lub bitmap thiab mam li thov ib qho screen rau lub bitmap.
Ua ib qho ntxiv lawm, peb tab tom yuav qhia koj li cas kom thev xim rau daim duab hauv Daim Pej Xeem CC uas yog ib txoj kev uas peb tau kawm los ntawm Illustrator Guru Carlos Garro.
Cia peb pib.

Ntxiv Dub thiab Dawb Txheej Txheej
Peb yuav mus ua haujlwm nrog ib daim duab ntawm ib tug nyuj ntawm ib thaj teb hauv Bern, Switzerland. Thawj kauj ruam hauv tus txheej txheem yog ntxiv rau Dub thiab Dawb Txheej Txheem . Thaum lub sijhawm qhib txheej dialog box qhib koj yuav xav yog vim li cas muaj cov xim yawg? Cov xim tua cov xim tswj kev hloov ntawm cov xim raws thiab lawv qhov sib txawv rau cov xim greyscale. Piv txwv li, tus nyuj nyob rau hauv thawj daim duab tau xim av plaub. Yuav kom coj li cov kev nthuav dav hauv cov pluab liab liab slider tau tsiv mus rau sab laug kom tsaus ntuj me ntsis ntxiv. Lub ntuj xiav thiab muab lub sijhawm sib txawv ntawm nws thiab tus nyuj dawb lub ntsej muag, xiav qhov xiav tau txav mus rau sab xis.
Yog tias koj xav ntxiv qhov sib txawv me ntsis ntxiv rau cov duab, ntxiv Cov Kev Txhim Kho Ntxiv thiab, ua qhov muag ntawm qhov kev nthuav dav, tsiv mus rau Black slider rau sab xis thiab Dawb slider mus rau sab laug.

Hloov mus rau Bitmap
Peb lub hom phiaj ntawm qhov kawg yog los hloov cov duab rau Bitmap hom ntawv. Hom ntawv no thiaj li tau cov duab rau ob hom xim dub thiab dawb. Yog tias koj xaiv Duab> Hom koj yuav pom tias Bitmap hom tsis txaus. Yog vim li cas, yog tias koj saib ntawm cov ntawv qhia zaub mov, daim duab no tseem tseem pom los ntawm Photoshop raws li nyob hauv RGB xim qhov chaw.
Ua cov duab xaiv> Hom> Grayscale. Qhov no yuav hloov cov duab los ntawm nws cov xim tam sim no thiab hloov cov ntaub ntawv RGB xim nrog greyscale vales. Qhov no yuav ua rau kev ceeb toom qhia koj tias kev hloov cov hom yuav tshem tawm Cov Kev Nkag Nkoj thiab nug koj yog tias koj xav ua qhov no los yog ua kom pom tus duab. Xaiv Flatten .
Koj yuav pom lwm tus Alert nug koj yog tias koj xav kom tshem ntawm Dub thiab Dawb Txheej Txheej thiab cov duab cov duab xim. Tshem pov tseg . Yog tias koj rov qab mus Duab> Hom koj yuav pom Bitmap tam sim no muaj. Xaiv nws.

Txhim Kho Daws Tau
Thaum koj xaiv Bitmap ua hom duab, lub Bitmap Dialog lub thawv qhib thiab nug koj kom txiav txim siab ob peb.
Thawj yog kom txiav txim siab seb cov lus daws teeb meem twg siv. Txawm hais tias Golden Txoj Cai yeej tsis tau nce ib qho duab daws teeb meem, qhov no yog ib qho ntawm cov uas tsis tshua muaj qhov uas nce qhov kev daws teeb meem yuav tsis muaj qhov cuam tshuam zoo li qhov kawg. Nyob rau hauv rooj plaub ntawm cov duab no, qhov kev daws teeb meem tau nce mus rau 200 Pixels / Ntiag.
Cov nqe lus nug tom ntej yog qhov kev siv rau kev hloov dua siab tshiab. Cov pop cia muaj ntau txoj hau kev, tiam sis peb lub tswv yim yog los tsim cov nyhuv Halftone. Dab tsi qhov no yog tig cov duab rau hauv ib phau ntawm cov dots. Xaiv Halftone Screen thiab nias OK.

Qhov muaj nuj nqi pes tsawg zaus, thaum muaj qhov "Yuav ua li cas ..." yuav txiav txim siab qhov loj ntawm cov dots. Peb mus nrog 15 kab ib nti .
Lub pob muaj nuj nqi yog qhov koj yuav tau xav. Qhov no yog lub kaum sab xis cov npav yuav raug teem rau. Piv txwv, tus nqi ntawm 0 yuav ua txhua kab ntawm cov kab hauv txoj kab ncaj nraim horizontally los yog vertically. Lub neej ntawd tus nqi yog 45 .
Cov hom pop cia txiav txim siab seb hom dots siv. Rau qhov no, peb xaiv Round .
Nyem OK thiab tam sim no koj saib ntawm "retro" bitmap duab.
Yog xav paub ntxiv txog Bitmap hom, kos tawm cov ntawv Photoshop.
Txij ntawm no tus taw tes koj tuaj yeem txuag tau cov duab ua tus duab jpg lossis .psd. Vim qhov tseeb cov duab no yog muab los rau Illustrator CC, peb tau txais kev cawmdim cov duab ua cov ntaub ntawv .tiff.

Yuav Ua Li Cas Thiaj Coj Li Tiav .TIFF Nyob Hauv Tsev Adobe Illustrator CC 2017
Ib qho ntawm peb cov Photoshop Tutorials qhia koj tias yuav ua li cas tig ib tug yees duab rau hauv comic phau kos duab nyob rau hauv cov style ntawm Roy Lichtenstein . Cov txheej txheem no yog ib qho kev hloov ntawm qhov uas siv cov khoom bitmap uas tsis yog xim duab.
Ntxiv cov xim, Cow.tif duab tau qhib rau hauv CC Lub Kos. Yog vim li cas rau qhov kev txiav txim siab yog qhov tseeb tias hom ntawv .tif yog ib qho pixel-bitmap hom thiab cov dots tuaj yeem siv Colour Illustrator xim. Ntawm no yog li cas:
