Koj puas tau txiav txim siab pleev xim lossis pleev xim rooj tog? Tab sis tsis paub yuav ua li cas kom tau txais cov ntxoov ntxoo sib txawv? Xim sib xyaw cov kab kos thiab cov lus qhia yuav pab koj ua qhov ntawd.

Basic concepts

Ua ntej koj pib kawm cov xim sib xyaw cov ntxhuav, koj yuav tsum paub koj tus kheej nrog qee cov ntsiab lus uas yuav ua rau nws yooj yim to taub cov khoom tshiab rau koj tus kheej. Cov lus siv nyob rau hauv txoj kev xav thiab kev xyaum ntawm kev sib xyaw xim yog piav qhia hauv qab no. Cov no tsis yog scientific encyclopedic txhais, tab sis transcripts nyob rau hauv ib hom lus to taub rau ib tug dog dig beginner, tsis muaj lub xub ntiag ntawm complex terminology.

Achromatic xim yog txhua qhov nruab nrab ntxoov ntxoo ntawm dub thiab dawb, uas yog, grey. Nyob rau hauv cov xim no tsuas muaj ib tug tonal tivthaiv (tsaus - lub teeb), tab sis tsis muaj "xim" li ntawd. Cov uas nws hu ua chromatic.

Cov xim tseem ceeb yog liab, xiav, daj. Lawv tsis tuaj yeem tau los ntawm kev sib xyaw lwm yam xim. Cov uas tuaj yeem ua ke.

Saturation - tus yam ntxwv uas paub qhov txawv ntawm cov xim chromatic los ntawm qhov pom kev zoo ib yamachromatic xim. Tom ntej no, xav txog dab tsi lub rooj sib xyaw xim rau kev kos duab yog.

Spectrum

Cov kab kos xim sib xyaw feem ntau yog nthuav tawm raws li cov duab plaub lossis cov squares, lossis ua cov duab ntxoov ntxoo sib xyaw nrog cov lej lossis feem pua ntawm txhua qhov xim.

Cov lus hauv qab yog cov spectrum. Nws tuaj yeem piav qhia raws li kab txaij lossis lub voj voog. Qhov kev xaiv thib ob yog qhov yooj yim dua, pom thiab nkag siab. Qhov tseeb, lub spectrum yog ib tug schematic sawv cev ntawm ib tug beam ntawm lub teeb decomposed rau hauv cov xim, nyob rau hauv lwm yam lus, ib tug zaj sawv.

lub rooj no muaj ob qho tib si thawj thiab theem ob. Qhov ntau sectors nyob rau hauv lub voj voog no, ntau dua tus naj npawb ntawm nruab nrab ntxoov. Nyob rau hauv daim duab saum toj no, kuj muaj gradations ntawm lightness. Txhua lub nplhaib sib raug rau ib lub suab nrov.

Txoj xim ntawm txhua ntu yog tau los ntawm kev sib xyaw xim nyob sib ze hauv lub nplhaib.

Yuav ua li cas sib tov achromatic xim

Muaj cov txheej txheem pleev xim zoo li grisaille. Nws koom nrog kev tsim cov duab uas siv gradations ntawm cov xim achromatic nkaus xwb. Qee zaum xim av lossis lwm qhov ntxoov ntxoo ntxiv. Hauv qab no yog lub rooj sib xyaw xim rau cov xim thaum ua haujlwm li no.

Thov nco ntsoov tias thaum ua haujlwm nrog gouache, roj, acrylic, ib qho ntxoov ntxoo grey yog tsim tsis tsuas yog los ntawm kev txo cov xim dub, tab sis kuj los ntawm kev ntxiv dawb. Hauv dej ximCov kws tshaj lij tsis siv cov xim no, tab sis dilute cov xim nrog dej.

Yuav ua li cas nrog dawb thiab dub

Yuav kom tau txais qhov tsaus ntuj lossis sib zog ntxoov ntxoo ntawm cov xim uas koj muaj hauv cov khoom siv, koj yuav tsum sib tov nrog cov xim achromatic. Qhov no yog li cas gouache ua haujlwm, sib xyaw cov xim acrylic. Cov lus hauv qab no haum rau txhua yam khoom siv.

Cov khoom siv los ntawm cov lej sib txawv ntawm cov xim npaj txhij, yog li sib piv qhov koj muaj nrog ntxoov ntxoo koj xav tau. Los ntawm kev ntxiv dawb, koj yuav tau txais cov xim pastel.

Cov hauv qab no qhia tau hais tias ob peb xim nyuaj npaum li cas los ntawm lub teeb heev, yuav luag dawb, mus rau tsaus heev.

Cov lus hauv qab no tuaj yeem siv tau rau ob qho tib si glazing thiab ib txheej txheej pleev xim. Qhov txawv yog hais tias nyob rau hauv thawj version, qhov kawg ntxoov ntxoo yog tau los ntawm visually txuas txawv tones superimposed ib tug nyob rau sab saum toj ntawm lwm yam. Qhov thib ob txoj kev koom nrog cov neeg kho tshuab tsim cov xim uas xav tau los ntawm kev sib txuas cov xim ntawm cov palette.

Yuav ua li cas qhov no yog qhov yooj yim to taub los ntawm saib thawj kab nrog cov xim liab hauv daim duab saum toj no. Laying yog ua li no:

  1. Sau tag nrho cov squares nrog lub suab nrov uas koj tau txais nrog cov xim me me thiab dej ntau.
  2. Tom qab ziab, tib yamsiv xim rau cov khoom thib ob thiab thib peb.
  3. Rov ua cov kauj ruam ntau zaus raws li xav tau. Hauv cov ntawv no, tsuas muaj peb lub hlwb hloov xim, tab sis yuav muaj ntau dua.

Thaum ua haujlwm hauv cov txheej txheem ntawm kev pleev xim rau glazing, nws tsim nyog nco ntsoov tias nws yog qhov zoo dua los sib xyaw cov xim sib txawv tsis pub ntau tshaj tsib txheej. Yav dhau los yuav tsum tau qhuav kom zoo.

Yog tias koj npaj cov xim uas yuav tsum tau ua tam sim ntawd ntawm lub palette, qhov sib lawv liag ntawm kev ua haujlwm nrog tib xim ntshav gradation yuav ua raws li hauv qab no:

  1. Npog cov xim los ntawm kev siv txhuam ntub nrog qee cov xim. Siv rau thawj daim duab plaub.
  2. Ntxiv cov xim, sau cov khoom thib ob.
  3. Muab txhuam rov qab rau hauv cov xim thiab ua ib lub xov tooj thib peb.

Thaum ua haujlwm hauv ib txheej, koj yuav tsum xub sib tov tag nrho cov xim ntawm lub palette. Qhov no txhais tau hais tias nyob rau hauv thawj txoj kev, qhov kawg ntxoov ntxoo yog tau los ntawm optical mixing, thiab nyob rau hauv lub thib ob - mechanical.

Gouache thiab roj

Techniques rau kev ua hauj lwm nrog cov ntaub ntawv no zoo sib xws, vim cov pigments yeej ib txwm nthuav tawm nyob rau hauv daim ntawv ntawm ib tug creamy loj. Yog hais tias gouache qhuav, nws yog pre-diluted nrog dej mus rau qhov xav tau sib xws. Dawb yog ib txwm muaj nyob rau hauv txhua lub teeb. Lawv feem ntau khiav tawm sai dua li lwm tus, yog li lawv muag hauv ib lub hub lossis cov raj.

Kev sib xyaw cov xim roj (cov lus hauv qab), zoo li gouache, yog ib txoj haujlwm yooj yim. Qhov kom zoo dua ntawm cov txheej txheem no yog tias txheej tom ntej no sib tshooj tag nrho cov yav dhau los. Yog tias koj ua yuam kev thiab tom qab ziab koj tsis nyiam qhov ntxoov ntxoo, ua ib qho tshiab thiab siv nwssaum toj no. Cov yav dhau los yuav tsis qhia los ntawm yog tias koj ua hauj lwm nrog cov xim tuab, tsis diluting lawv nrog kua (dej rau gouache, hnyav rau roj).

Paintings nyob rau hauv no painting txheej txheem txawm yuav textured, thaum ib tug tuab tuab yog thov pasty, uas yog, nyob rau hauv ib tug tuab txheej. Feem ntau, cov cuab yeej tshwj xeeb yog siv rau qhov no - riam palette, uas yog hlau spatula ntawm tus kov.

Qhov feem ntawm cov xim yuav tsum sib xyaw thiab cov xim tsim nyog kom tau txais qhov ntxoov ntxoo uas xav tau yog pom nyob rau hauv daim ntawv teev dhau los. Nws yog tsim nyog hais tias nws yog txaus kom muaj tsuas yog peb thawj xim nyob rau hauv lub teeb (liab, daj thiab xiav), raws li zoo raws li dub thiab dawb. Los ntawm lawv, nyob rau hauv sib txawv ua ke, tag nrho lwm cov ntxoov yog tau. Qhov tseem ceeb tshaj plaws yog cov xim nyob rau hauv lub thawv yuav tsum yog raws nraim lub ntsiab spectral tones, uas yog, piv txwv li, tsis liab los yog raspberry, tab sis liab.

Ua haujlwm nrog acrylics

Feem ntau cov xim no ua haujlwm ntawm ntoo, duab los qhia, iav, pob zeb, ua cov khoom siv dai kom zoo nkauj. Hauv qhov no, kev sib xyaw ntawm cov xim tshwm sim tib yam li thaum siv gouache lossis roj. Yog hais tias qhov saum npoo tau pre-primed thiab cov xim yog haum rau nws, tau txais qhov xav tau ntxoov ntxoo tsis yog qhov nyuaj. Hauv qab no yog cov piv txwv ntawm kev sib xyaw ntxoov ntxoo nrog acrylic.
