Txawm freelancers khoom siv muaj ke - thiab ua rau kom cov kev ceev thiab zoo tshaj ntawm kev ua hauj lwm.

Yuav ua li cas yog nws?

Zaus decomposition - ib zaus decomposition. Lub sij hawm yog siv tsis tau tsuas yog nyob rau hauv cov kev kho mob ntawm portraits, tab sis nyob rau hauv kev kawm txog zauv, suab paj nruag, thiab lwm tus neeg. Rau retoucher uas txhais tau tias tus yees duab kis ntawm ob peb khaubncaws sab nraud povtseg (pes tsawg zaus), e.g., cov txheej qhov chaw thiab lub suab nrov txheej, txhua tus uas yog edited nyias los ntawm lwm tus.

Vim qhov no tsab xov xwm no muaj nyob rau hauv cov zaj lus qhia ntawm "Photoshop" rau beginners, nws yuav tsom rau yuav ua li cas piav qhia txog lub hauv paus ntsiab lus ntawm ncaj qha zaus decomposition thiab nthuav dav uas cov tub txawg tau ntev lawm paub.

zaj dabneeg

Khoos phib tawj graphics thiab ua raws li nyob rau hauv lej cai, tab sis yog tej zaum cov creators rau tsis muaj ntaub ntawv. Yog li, qhov zaus thiab lub expansion tuaj los ntawm cov Fourier decomposition rau hauv zaus txiav txim: thawj xyuam xim txoj kev borrowed los ntawm xov tooj cua, thiab ces - qhov musicians, thiab thaum kawg retouchers.

"Photoshop" Cov tshooj lus rau Beginners tsis tshua muaj cov ntaub ntawv, thiab nyob rau hauv cov formulas lej yog tiag tiag tsis muaj yuav tsum tau. Txawm li cas los, yog dab tsi tam sim no tus nqi, yuav tseem yuav tau ib tug me ntsis ntxiv.

Yog vim li cas ua tau nws?

Retouching lub frequencies siv nyob rau hauv tus neeg mob ntawm lub teeb liab ua ala Naturel. Nyob rau hauv lwm yam lus, Yog hais tias zaum kawg tshwm sim yuav tsum yuav ib lub ntuj, es ib tug glossy ua. Tsis tas li ntawd, ua raws li tau piav rau hauv qab no yog ntau npaum li cas muaj tseeb thiab high-zoo txhais tau tias lub siab tshaj plaws degree ntawm craftsmanship.

Tsis zoo li cov pa txoj kev ua

Glossy yees duab retouching nyob rau hauv "Photoshop" yog nqa tawm nrog kev pab los ntawm qhov ncauj qhov ntswg thiab ntau hom plooj. Qhov no ua rau ntawm daim tawv nqaij ntawm ib tug portrait heev thiab xub npus, thiab "nws yog tseeb hais tias kho". Rau tej tswv yim, xws li ib tug tshwm sim yog qhov kev kawm, tab sis nyob rau hauv cov ntaub ntawv ntawm tej yam ntuj tso portraits ua yuav tsum tsis txhob yuav pom. Qhov no yog ua los ntawm nkauj nraug lub khaubncaws sab nraud povtseg ntawm txhua lwm yam - retouching ib tug ntawm lawv, peb tsis txhob kov lwm yam.

Yog nws tsuas yog rau cov portraits yuav siv tau?

Ntawm cov hoob kawm, tus taboo "rau kev siv tsuas portrait ntawm" tsis muaj rau cov txheej txheem no. Thiab txawm hais tias rau qhov no, thiab ib tug xov tooj ntawm lwm cov khoom nyob rau hauv Internet, tej zaum koj yuav xav tias nws yog rau lawv nws yog ib qhov zoo tshaj, nws tsis yog. Portraits ua li tus tsov ntxhuav feem ntawm lub lag luam cov duab, thiab retouch yeej los ua ntej, tab sis lub zaus decomposition yog universal thiab zoo tagnrho rau tag nrho cov duab nyob qhov twg muaj ib tug xav los kav qhov chaw nyias los ntawm txhua lwm yam.

Raws li deb raws li kis zaus?

Nws muaj ob hom ntawm zaus decomposition nyob rau hauv lub "photoshop":

1. Cov tawv nqaij splits rau hauv ob frequencies - lub suab nrov thiab nthuav dav. Nyob rau hauv thawj daim tawv nqaij txheej yog smoothed, lub thib ob ntxuav tsis xws luag (wrinkles, ntxau, etc.).
2. Lub decomposition yog nqa tawm ntawm peb frequencies - siab, medium thiab tsawg. Siv ib tug los ze zog saib hauv qab no.

thawj kauj ruam

Tsis hais txog ntawm uas txoj kev yog txiav txim siab los siv lub pre-yuav tsum tau qhib cov duab nyob rau hauv "Photoshop" thiab ua ntau yam cov ntawv luam ntawm nws cov khaubncaws sab nraud povtseg - tus nqi nyob rau hauv tus qauv. Nyob rau hauv thawj rooj plaub uas nws tsim ob cov ntawv luam ntawm cov txheej, nyob rau hauv lub thib ob - ob.

Zaus decomposition nyob rau hauv "Photoshop" mus rau hauv ob khaubncaws sab nraud povtseg

Raws li twb hais saum toj no, raws li cov thawj txheej rau cov qauv no cov laus tawv nqaij yog muab raws li lub thib ob - cov khoom.

Tom qab tsim ob cov ntawv luam ntawm cov khaubncaws sab nraud povtseg nws yog pom zoo kom tsim ib tug nyias muaj nyias ib pab pawg neeg ntawm khaubncaws sab nraud povtseg rau lawv. Qhov no yog nyob ntawm yeem, tiam sis nws yog suav tias yog zoo xyaum kom muaj shaders thiab feem ntau uproschyaet ua hauj lwm. Group nyob rau hauv lub "Photoshop" - feature cov tub txawg.

Nws kuj pom zoo kom muab lub npe kom tsim nyog khaubncaws sab nraud povtseg kom yooj yim: "Tone" thiab "Paub meej" thiab "Paub meej" saum toj no ib tug "Tone".

Ntxiv retouching dluab nyob rau hauv "Photoshop" pib nyob rau hauv tej hom: qhib txheej "Tone" thiab thov nws "Gaussian Plooj".

plooj qhov tseem ceeb feem ntau mas nws txawv nyob rau hauv ntau ntawm 7 mus rau 10 (siab tshaj qhov tus xov tooj, tus loj dua cov duab. Nyob rau hauv tej rooj plaub, yuav ncav cuag mus txog 15). Lub caij nyoog tooj ntawm xaiv retoucher tus kheej - zavimosti nrog duab loj thiab ob lub qhov muag. Lw tus plooj - thaum ntawm daim tawv nqaij yog smoothed, tab sis tus duab thiab qhov yooj yim kom paub meej tseem tshwmsim.

Tom qab ntawd mus rau lub thib ob txheej. Nws yuav tsum tau pre-npaj. Rau tag nrho cov ntsiab lus ntawm cov "txiav los ntawm" lub lim yog siv "Xim Zoo". Nyob rau hauv "Photoshop" cov lus Askiv-cov lus suab zoo li lub High Pass. Nyob rau hauv lub lim zaub mov (Flter) - Lwm yam (Lwm yam). Nyob rau hauv Feem ntau, qhov no tsab xov xwm no qhia txog yuav ua li cas zaus decomposition nyob rau hauv "Photoshop" kauj ruam yog kauj ruam nyob rau hauv Lavxias teb sab, tab sis cov neeg uas siv cov software nyob rau hauv lus Askiv, yuav kuj yuav pab tau.

Sharpness "xim zoo ib" yuav configured nyob rau hauv tib txoj kev raws li cov "Gaussian Plooj." Tus nqi zoo xws li cov - yog hais tias lub txheej "Tuj" yog xaiv tau lub xov tooj 12, rau lub "Paub meej" nws yog sib npaug zos rau 12 lub tib yam. Cov tshwm sim ntawm thov ib lim - grey nyem duab.

thib ob txhais ceg

Rau ib txheej ntawm "Paub meej", "blending hom" yog hloov mus rau "Tawm teeb". Yog hais tias cov duab zoo yuav dhau lawm - yuav tsum tau mus rau lub tab Curves thiab txo tus zoo ib. Xwb: txo zoo "cov laus txoj kev" los ntawm zuj zus lawm cov parameter "zoo".

Nws tus kheej pes tsawg zaus decomposition twb tau ua li cas - yog tsuas mus tshem tawm cov tsis xws luag los ntawm qhov chaw txhuam. Nws yog yooj yim, tab sis zog ua hauj lwm. Txhuam pom zoo kom coj ib tug me ntsis flattened daim ntawv (nyob rau hauv ustanalivaetsya tsis). Nws yuav tsum tau mus los ntawm lub duab tag nrho thiab tshem tawm cov tsis xws luag.

Ceeb toom! Tshem me me ntxau thiab wrinkles, koj yuav tsum tau tawm cov kab uas ua rau lub duab anatomically tseeb thiab muaj feem xyuam rau cov kev zoo sib thooj ntawm cov ntsej muag nyob rau hauv lub portrait.

lus hais

Peb piav qhia txog ib tug yooj yim txheej txheem, tab sis muaj lwm version ntawm no txoj kev. Raws li tau piav rau hauv qab no yuav nqa tawm nyob rau hauv lub zaus decomposition "Photoshop CS6" thiab saum toj no.

Thaum ua hauj lwm nrog fiber "Paub meej" es tsis txhob lim "xim zoo ib" mus rau "Sab nraud Channel" (Duab tab), tsis los ntawm hlauv daim ntawv teev rau xaiv txheej "Tone" (nws tsis yog ib tug typing kev ua yuam kev, xaiv lub tiag tiag "laus") thiab nias OK.

Blending hom thiab ces hloov mus rau "Tawm teeb". Tag nrho cov kev ua yog ua nyob rau hauv lub saum toj no kev txiav txim.

Tseem Ceeb! Yog hais tias lub "Gaussian Plooj" tau muab tawm sis tsis ncaj thiab ua cov nqi heev "razmylivaet" cov ntsiab lus, koj yuav plooj lub thib ob lub sij hawm sis tsis ncaj chaw siv lub "lasso" cuab tam. Nws yog tau faib qhov tsim nyog qhov chaw ntawm daim duab plooj tom qab uas yog thov tsuas mus xaiv feem.

Decomposition rau peb frequencies

Zaus decomposition rau hauv peb khaubncaws sab nraud povtseg nyob rau hauv lub "Photoshop" yog ua los ntawm cov cai xws li cov ob tug. Nyob rau lwm cov tes, ib tug peb-txheej decomposition los ze zog mus rau lawv pog koob yawg koob - lub Fourier decomposition, thiab siv nws yog yooj yim los mus piav qhia txog lub hauv paus ntsiab lus ntawm expansion.

Yog li, coj raws li ib lub hauv paus rau hauv lub, nruab nrab thiab sab zaus. Lub retouching cheeb tsam nyob rau hauv lub siab frequencies yog cov kev yam ntxwv ntawm daim ntawv no, nyob rau hauv nruab nrab - kev ntxhib los mos ntawm tus nto, raws li zoo raws li tag nrho cov tsis xws luag thiab me ntsis nyob rau hauv lub qis - Ntaub ntawv hais txog lub teeb thiab zaus. Tom qab no piav qhia txog nws yog ib qho yooj yim mus xaus hais tias cov khaubncaws sab nraud povtseg ntawm "laus" thiab "Paub meej" - tsis yog hais tias lwm yam, raws li lub Upper thiab qis frequencies.

Qhov chaw frequencies nyob rau hauv lub saum toj no txoj kev uas muaj thiab merged ntawm nws tus kheej edited vim hais tias cov qauv ntawm cov zaus decomposition rau peb txheej uas muaj tseeb thiab zoo dua. Xav txog nws.

Zaus decomposition rau hauv peb khaubncaws sab nraud povtseg nyob rau hauv theem

Ua ntej koj yuav nqa tawm lub expansion, nws yog tsim nyog los ua ib yam ua ntej ua cov duab. Nws yog pom zoo kom ib tug daim ntawv ntawm no txheej.

Nthuav! Ib daim ntawv ntawm cov txheej, koj muaj peev xwm tsim nias cov yam khoom los ntawm lub ntsiab lus teb ntawv qhia zaub mov los yog los ntawm txhaj rau cov coj icon nyob rau hauv qab ntawm lub qhov rais khaubncaws sab nraud povtseg. Tsis tas li ntawd, qhov kev txiav txim yog ua los ntawm ib tug ua ke ntawm lub lag luam Ctrl + J. Ntsiab ob peb ua ke yog ib qho tseem ceeb nyob rau hauv "Photoshop", lawv leeb nws thiab ua rau nws swm. Ntawm cov hoob kawm, tus thawj thaum lawv tseem yog tsis nco qab txog, thiab yuav tsis muab siv rau lub tshuab, tab sis nyiaj mus dhau txoj kev hloov lub sij hawm, nco ntsoov, ua ib tug tswv - nws yog tsim nyog nws.

Nyob rau ib tug tshiab txheej tsis xws luag raug muab tshem tawm los ntawm txhais tes point. Nws yog tsawg zog ua hauj lwm tshaj lub xeem point, vim hais tias muaj yog tsis muaj yuav tsum tau tshem tawm cov me ntsis tej yam uas - nyob rau hauv cov ntaub ntawv no, qhov luaj li cas ntawm tus txhuam yog coj ntau thiab cia li daws ib yam dab tsi uas yeej catches lub qhov muag thiab yuav cuam tshuam nrog rau-up kev ua hauj lwm.

Tom ntej no, tsim peb cov ntawv luam ntawm cov ua txheej. Hu ua tus "High" (High), "Zuaj dav hlau" (Middle) thiab "tsis tshua muaj" (Low). Qhov no yog ua li cas, raws li tau hais ua ntej, kom yooj yim. Pib retouching yuav tau ob leeg siab zaus thiab tsawg - yog tsis muaj qhov sib txawv.

Nyob rau hauv no tsab xov xwm, wb mus los ntawm lub sab saum toj cia, uas yog, pib nrog cov "Tsawg".

Nyob rau hauv txheej "Tsawg" superimposed "Gaussian Plooj". Tsis zoo li cov qauv ntawm cov decomposition rau hauv ob khaubncaws sab nraud povtseg, lub plooj parameter tej zaum yuav mus txog 30. Qhov loj tshaj plaws - xaiv tus xov tooj uas tus laus tawv nqaij yuav tsum niaj hnub zoo li.

Rau ib txheej ntawm "High" lim xaiv "xim zoo ib". Tus nqi "xim zoo ib" yuav tsum ua tau peb lub sij hawm tsawg "Gaussian plooj".

Layfak: teev tsis muaj khaubncaws sab nraud povtseg nyob rau hauv lawv lub npe. Yog hais tias cov xov tooj ntawm 30-10, lawv yog ib qho yooj yim uas yuav tau nco, tab sis ua hauj lwm nrog cov 12.7, nws yog zoo dua mus hlawv.

Txheej "Tsawg" yuav muaj plooj (plooj), thiab sib piv. Plooj nqi sib npaug zos rau cov nqi "xim zoo ib" nyob rau hauv txheej "High" (nyob rau hauv qhov kev piv txwv, 30) thiab tus zoo tus nqi ntawm cov plooj nyob rau hauv lub "Tsawg" (10).

Rau tag nrho peb khaubncaws sab nraud povtseg tsim ib pab pawg neeg. Decomposition yog npaj txhij, koj muaj peev xwm pib editing.

Yuav ua li cas yog txhua yam ntawm lub frequencies?

Txheej "nruab nrab" xws li muaj tag nrho cov tsis xws luag. Tshem nws kiag li undesirable. Yuav kom tshem tawm cov pob, koj yuav tsum tsim ib daim npog qhov ncauj (Alt + Daim npog qhov ncauj icon nyob rau hauv qab ntawm lub qhov rais khaubncaws sab nraud povtseg), thiab ces ib tug dub txhuam los tuav lub portrait nyob rau hauv qhov chaw nyob qhov twg muaj irregularities.

Nyob rau hauv tib txoj kev uas nws muaj peev xwm yuav kho tau nrog ib tug txheej ntawm "High" nyob rau hauv thiaj li yuav txhim kho lub uniformity ntawm daim tawv nqaij laus. Nyob rau tib lub txheej, ua hauj lwm nrog rau xim - obscure thiab tinting qhov tsim nyog qhov chaw, evens.

tau daim ntawv sau npe

Nyob rau hauv tas li ntawd mus studio portraits, nyob rau hauv uas koj xav kom tshem tau ib tug ob peb ntxau, ua ntej retouching txoj kev zaus decomposition nyob rau hauv "Photoshop" yuav tsum muab tso rau txawv cov hom phiaj. Yog li, nws yuav tsum muaj ntaub ntawv nyob rau hauv xws li mob:

1. Thov txhim kho lub clumsy ua hauj lwm ntawm pleev - nyob rau hauv lwm yam lus, kom hloov tus pleev. Nws yog tseem tau mus thov ib tug ua-up ntawm kos. Nyob rau hauv lub caij nyoog kawg no rooj plaub no nws yog pom zoo kom muaj nyob rau hauv cov kev yees duab ntawm lub tib lub qauv uas muaj make-up rau lwm yam daim ntawv thov kev ntseeg.
2. Mos muted daim tawv nqaij ntxhib los mos - yooj yim thiab yog kov-up, tsis muaj tus cuam tshuam rau tus txhais tes thiab taw tes "zamylenny" Bloor.
3. Chais plaub tug txiv neej - yuav tsum tau ib tug ua ke ntawm zaus decomposition txoj kev, thaum lub zog ua hauj lwm yog tau ib tug zoo tshwm sim.

Cov kev ceev ntawm

Txawm tias muaj tseeb hais tias cov txheej txheem mas, yooj yim, tom qab lub expansion ntawm lub txaus siab heev, ua hauj lwm rau tag nrho peb khaubncaws sab nraud povtseg zaus tseem yuav laborious. Txawj retoucher ua hauj lwm rau tej "trifles" raws li tus duab ntxoov ntxoo thiab highlights, lub volume duab. Zaus decomposition - tsis yog lub txoj kev nyob rau hauv ib tug nias mus txia ib tug yees duab, tab sis, nyob rau hauv tsis tooj, nws cov txheej txheem ntawm sib sib zog nqus txoj kev tshawb no.

Cuaj kaum, zauv txoj kev moj khaum qhia yuav ua li cas nws yuav tsum caw kaw lus.

programmatically

Rau "Photoshop" (rau "Gimp", nws "Linuksovskogo" tus kwv tij, los ntawm txoj kev, ib yam nkaus thiab), muaj tshwj xeeb plug-ins, raws li zoo raws li qhov kev txiav txim ua si. Tag nrho cov ntawm lawv yog tsis qoos automate retouching duab (thaum kawg, nws tseem yog cov muaj tswv yim txoj kev), tab sis programmatically ua tej yam ua yuav tsim tau lub tsim nyog khaubncaws sab nraud povtseg thiab lawv tej chaw. Qhov no zoo heev simplifies zaus decomposition nyob rau hauv "Photoshop".

Action (txiav txim - txiav txim lag luam) - ib cov ntaub ntawv nrog rau cov extension lub ntsaum, uas yog ib tug txheej ntawm kev ua hauj lwm nyob rau hauv "Photoshop". Nws muaj peev xwm txawm yuav hu ua ib tug mini-kev pab cuam. txiav txim cov ntaub ntawv twb muaj muaj siv lub tab "Qhov rai" - "hauj lwm."

Kev txiav txim rau zaus decomposition, yog xav, koj muaj peev xwm tsim koj tus kheej - rau manually ua tag nrho cov saum toj no ua thiab mus rau tag nrho cov tib tab "Operations", thiab ces nias rau ntawm lub icon los tsim ib tug tshiab lub lag luam. Rau kom yooj yim, nws yog pom zoo kuj mus tsim ib co kev ua si los ua ib tug nyias muaj nyias ib lub ib, ob thiab thib peb khaubncaws sab nraud povtseg.

Ua ua si uas muaj nyob rau download nyob rau hauv internet pab, tiam sis nws tseem pom zoo kom tsim lawv tus kheej - sim ua ntej zaus decomposition los ntawm txhais tes, thiab ces xam seb yuav siv nws, thiab ces automate txheej txheem no rau yav tom ntej siv. Nyob rau hauv tas li ntawd, daus los ntawm hauv Internet yeej ib txwm implies tau daus ib tus kab mob no. Yog li ntawd nws yog zoo dua rau muaj kev ruaj ntseg.

Zoo li tej kev pab cuam, ua si yog muaj rau editing thiab hloov li cas muaj tau sau los ntawm lwm tus neeg, - yog nyuab dua. Nyob rau hauv tas li ntawd, txhua tus neeg sau ua lub lag luam, ua ntej ntawm tag nrho cov, "los ntawm nws tus kheej", thiab xwb ces nyob rau hauv ib tug haum ntawm generosity kis nyob rau hauv lub Internet rau txhua leej txhua tus mus saib.

tshawb pom

Nyob rau hauv dav dav, lub zaus decomposition - ib tug heev haib cuab tam. Tus thawj txoj kev, nyob rau hauv uas tus txheej txheem yog nqa tawm nyob rau hauv ob khaubncaws sab nraud povtseg ntau ze mus rau li qub retouching thiab tsuas yog me ntsis lawd daim ntaub thaiv ntawm kev siv decomposition. Qhov thib ob, cov sawv cev ib tug hloov zauv lag luam muab loj loj uas duav txhua yam kom muaj tswv yim. Nyob rau hauv tsab xov xwm qhov tsawg kawg nkaus tau siv tau piav raws li nws cov hom phiaj - los tham txog qhov expansion ntawm nws yog dab tsi thiab yuav ua li cas yuav ua rau nws. Thiab absorbed nyob rau hauv lub npe ib tug me ntsis ntau, koj yuav nrhiav tau ib tug ntau ntau "chips".

Thaum kawg kuj muaj nqis mentioning uas yog ib tug muaj zaus decomposition tsis ua leej twg ib tug ntse heev retoucher. Zoo li tej cuab tam, nws yog zoo xwb nyob rau hauv cov kws muaj txuj ob txhais tes. Yog li ntawd, koj pom tus kawg txawm ua ntej thawj kauj ruam, daim ntawv ceeb toom cov tej yam me me thiab xwb ces xaiv lub twj paj nruag los ntawm txoj kev lawv zoo tshaj plaws rau kev txhim kho nws.
