Hauv Photoshop, nws yog ib qho tseem ceeb kom nkag siab txog lub tswv yim ntawm cov qauv vim tias cov qauv xim txiav txim siab cov qauv xim (tsuas yog, xim qauv yog lej lej siv los sawv cev xim) uas qhia thiab luam cov duab hluav taws xob, uas yog, yuav ua li cas cov duab hluav taws xob. tso tawm los yog luam tawm hauv lub computer. Hom xim muaj xws li hom bitmap, grey hom, ob-tone hom, HSB (rau xim, saturation, thiab brightness) hom, RGB (rau liab, ntsuab, thiab xiav) hom, CMYK (rau cyan, magenta, daj, thiab dub ) hom, Lab hom, index xim hom, multi-channel hom, thiab 8-ntsis / 16- ntsis hom. Txhua hom duab piav qhia thiab tsim cov xim sib txawv, nrog rau cov xim uas nws tuaj yeem tso tawm.

Thaum peb kawm PS digital inkjet luam ntawv xim sib xyaw, thawj qhov uas peb yuav tsum paub yog kev paub txog cov kev xav no. Tsuas yog los ntawm cov kev xav no tuaj yeem paub tias yuav ua li cas thiab tsis ua dab tsi hauv txhua kauj ruam ntawm kev ua haujlwm. Tom qab ntawd paub txog kev sib xyaw xim ntawm cov ntawv luam tawm digital, xws li siv ntau yam cuab yeej hauv PHOTOSHOP los hloov cov duab kos. Hauv qab no kos duab teeb Fang nrog koj los txheeb xyuas ntau yam xim qauv hauv PS, ua ntej nkag siab txog lawv cov muaj pes tsawg leeg.

Ntxiv rau qhov kev txiav txim siab ntawm cov xim uas tuaj yeem pom hauv cov duab, hom xim kuj cuam tshuam rau cov duab raws thiab cov ntaub ntawv loj. Cov channel uas tau hais ntawm no kuj yog lub tswv yim tseem ceeb hauv Photoshop. Txhua daim duab Photoshop muaj ib lossis ntau txoj hauv kev, txhua tus khaws cov ntaub ntawv hais txog xim xim hauv daim duab. Lub neej ntawd tus naj npawb ntawm cov xim raws hauv ib daim duab nyob ntawm nws hom xim. Piv txwv li, CMYK cov duab muaj tsawg kawg yog plaub txoj kab uas paub qhov txawv cov ntaub ntawv uas sawv cev rau cyan, magenta, daj, thiab dub. Ntxiv nrog rau cov kab xim qub no, cov channel ntxiv hu ua Alpha channels tuaj yeem ntxiv rau cov duab khaws cia thiab kho cov kev xaiv raws li daim npog ntsej muag, thiab cov xim xim tuaj yeem ntxiv. Ib daim duab qee zaum muaj li 24 channels. Los ntawm lub neej ntawd, hom bitmap, greyscale ob-xim thiab index xim dluab tseem muaj ib channel. RGB thiab Lab dluab muaj peb raws; CMYK cov duab muaj plaub kab.

I. HSB mode

HSB hom yog txhais raws li tib neeg lub qhov muag saib ntawm cov xim. Hauv hom no, txhua yam xim tau piav qhia los ntawm xim lossis lub suab, saturation, thiab ci ntsa iab.

1. Hwj chim (H)

Xim yog lub cev thiab lub siab lub ntsws tus yam ntxwv ntawm cov xim muaj feem xyuam rau lub ntsiab wavelength ntawm cov xim. Nws paub los ntawm kev sim uas txawv wavelengths ntawm pom lub teeb muaj xim sib txawv. Ntau wavelengths ntawm lub teeb sib tov nyob rau hauv sib txawv proportions yuav ua tau ntau yam xim, tab sis ntev li ntev raws li muaj pes tsawg leeg ntawm wavelengths yog ib yam, ces xim yog tej yam. Tsis muaj xim (dub, 100, grey) tsis muaj xim xim; Tag nrho cov xim (liab, txiv kab ntxwv, daj, ntsuab, cyan, xiav, violet, thiab lwm yam) yog cov cwj pwm uas qhia cov tsos ntawm cov xim. Lawv yog cov hues, qee zaum hues.

2. Saturation (S)

Saturation yog hais txog kev siv zog lossis purity ntawm cov xim, qhia qhov feem ntawm grey tivthaiv nyob rau hauv lub xim, qhia los ntawm 0 feem pua ​​​​rau 100 feem pua ​​(xim xim).

3. Brightness (B)

Brightness yog qhov sib txawv ntawm qhov ci ntawm cov xim thiab feem ntau ntsuas los ntawm 0 feem pua ​​(dub) txog 100 feem pua ​​(dawb).

Thib ob, RGB hom

RGB hom yog raws li kev sib xyaw ntawm peb lub ntsiab xim hauv qhov xwm txheej. Thawj xim ntawm liab (R), ntsuab (G) thiab xiav (B) raug muab tso rau hauv txhua qib xim raws li qhov ci ci ntawm {{0}} (dub) txog 255 (dawb), yog li qhia lawv cov xim. Thaum cov xim thawj ntawm qhov sib txawv ci sib xyaw, muaj 256 los ntawm 256 los ntawm 256 xim, lossis 16.7 lab. Piv txwv li, lub ci liab tuaj yeem muaj tus nqi R ntawm 246, tus nqi G ntawm 20, thiab tus nqi B ntawm 50. Thaum lub luminance qhov tseem ceeb ntawm peb cov xim thawj sib npaug, grey yog tsim. Thaum tag nrho peb qhov ci ci qhov tseem ceeb yog 255, dawb huv yog generated. Thaum tag nrho cov ci ci qhov tseem ceeb yog 0, cov xim dub yog tsim. Thaum peb hom xim sib xyaw, cov xim tsim feem ntau siab dua qhov qub xim ci ci, yog li txoj kev ntawm RGB hom los tsim cov xim kuj hu ua xim lub teeb ntxiv rau xim.

Thib peb, CMYK hom

CMYK xim hom yog hom luam ntawv. Plaub tsab ntawv hais txog Cyan, Magenta, Daj thiab Dub, uas sawv cev rau plaub xim ntawm number case hauv luam ntawv. CMYK hom tsis txawv ntawm RGB hom hauv cov ntsiab lus, tsuas yog lub hauv paus ntsiab lus ntawm xim xim txawv. Hauv hom RGB, cov xim yog tsim los ntawm kev sib xyaw cov xim tawm los ntawm lub teeb ci, thaum nyob rau hauv CMYK hom, xim yog tsim los ntawm lub teeb ci ntsa iab ntawm daim ntawv nrog ntau qhov sib txawv ntawm C, M, Y thiab K inks. Tom qab ib feem ntawm lub spectrum yog absorbed, lub teeb reflected rau tib neeg lub qhov muag generates xim. Raws li C, M, Y thiab K yog sib xyaw rau hauv cov xim, nrog rau kev nce ntawm plaub yam ntawm C, M, Y thiab K, lub teeb pom kev rau tib neeg lub qhov muag yuav tsawg thiab tsawg, thiab qhov ci ntawm lub teeb yuav yog. qis dua thiab qis dua. Txhua CMYK hom xim tsim txoj kev tseem hu ua xim rho tawm txoj kev.

4. Lab hom

Tus qauv ntawm Lab qauv yog tsim los ntawm CIE Society hauv 1931 raws li tus qauv rau kev ntsuas xim, thiab tau rov hais dua thiab hu ua CIELab hauv xyoo 1976. Hom no hais txog qhov sib txawv ntawm kev txhawb xim vim muaj cov khoom sib txawv thiab luam ntawv, uas yog, nws yog ntaus ntawv ywj siab.

Lab xim yog sawv cev los ntawm ib qho luminance tivthaiv L thiab ob xim yam a thiab b. Tus nqi ntau ntawm L yog 0-100, ib feem sawv cev rau qhov spectral hloov ntawm ntsuab mus rau liab, thiab b tivthaiv sawv cev rau spectral hloov ntawm xiav mus rau daj, thiab tus nqi ntau ntawm a thiab b yog {{1} }.

Lab hom muaj ntau yam xim, suav nrog txhua hom RGB thiab CMYK. CMYK hom muaj cov xim tsawg kawg nkaus, thiab qee cov xim uas nyob rau ntawm qhov screen tsis muaj nyob rau hauv luam.

5. Lwm hom xim

Ntxiv rau qhov yooj yim RGB, CMYK, thiab Lab hom, Photoshop txhawb (lossis txheej txheem) lwm hom xim, suav nrog hom bitmap, hom greyscale, hom ob-tone, hom xim xim, thiab hom multichannel. Thiab cov qauv xim no ua haujlwm tshwj xeeb. Piv txwv li, cov duab ntawm hom grey tsuas muaj cov nqi grey tab sis tsis muaj cov ntaub ntawv xim; Index Xim Hom Txawm hais tias koj tuaj yeem siv xim, piv rau RGB hom thiab CMYK hom, koj tuaj yeem siv xim tsawg heev. Cov qauv xim no tau piav qhia hauv qab no.

1. Bitmap hom

Bitmap hom siv ob xim (dub thiab dawb) los sawv cev pixels hauv ib daim duab. Bitmap-hom dluab kuj hu ua cov duab dub thiab dawb. Vim nws muaj qhov tob ntawm ib qho, nws tseem hu ua me ntsis duab. Txij li thaum hom bitmap tsuas yog sawv cev rau cov pixels ntawm cov duab hauv xim dub thiab dawb, ntau qhov kev nthuav dav ploj thaum hloov cov duab rau hom bitmap, yog li Photoshop muab ntau lub algorithms los simulate cov ntsiab lus uas ploj lawm hauv ib daim duab.

Nyob rau hauv cov ntaub ntawv ntawm tib qhov dav, qhov siab thiab kev daws teeb meem, hom bitmap muaj cov duab me me, uas yog li 1/7 ntawm hom grey thiab 1/22 ntawm RGB hom.

2. Greyscale hom

Grayscale hom tuaj yeem siv txog li 256 qib ntawm grey los sawv cev rau cov duab, ua rau cov duab hloov mus smoother thiab muag heev. Txhua pixel ntawm cov duab grayscale muaj qhov ci ci ntawm 0 (dub) thiab 255 (dawb). Tus nqi grey kuj tuaj yeem qhia tau los ntawm feem pua ​​​​ntawm cov xim dub (0 feem pua ​​​​yog sib npaug rau dawb, 100 feem pua ​​​​ntawm cov xim dub). Cov duab uas ua los ntawm cov xim dub los yog grey scale scanner feem ntau pom hauv cov nplai grey.

3. Duotone hom

Ob-tone hom siv 2-4 xim inks los tsim cov duab uas muaj ob-tone (2 xim), peb-tone (3 xim), thiab plaub-tone (4 xim) uas muab lawv qib. Nyob rau hauv tus txheej txheem ntawm hloov cov duab grayscale mus rau ib tug ob-tone hom, lub suab yuav raug kho los tsim tshwj xeeb los. Qhov tseem ceeb ntawm kev siv ob lub suab nrov yog siv ob peb xim raws li qhov ua tau kom pom cov xim ntau npaum li sai tau, uas yog qhov tseem ceeb kom txo cov nqi luam ntawv, vim tias hauv kev luam ntawv, txhua lub suab ntxiv yuav tsum tau them nqi ntau dua.

4. Indexed Xim hom

Index xim hom yog hom duab ntau hauv Is Taws Nem thiab cov animation. Thaum cov duab xim hloov mus rau cov duab xim xim, nws muaj ze li ntawm 256 xim. Daim duab index xim muaj lub rooj xim. Yog tias cov xim hauv cov duab qub tsis tuaj yeem sawv cev hauv 256 xim, Photoshop yuav xaiv cov xim uas muaj nyob ze tshaj plaws los simulate cov xim, yog li txo qhov loj ntawm cov ntaub ntawv duab. Siv los khaws cov xim hauv daim duab thiab tsim cov xim ntsuas rau cov xim. Lub rooj xim tuaj yeem txhais tau thaum lub sijhawm hloov dua siab tshiab lossis hloov kho tom qab thov kom ntsuas cov duab.

5. Multichannel hom

Multichannel hom yog pab tau rau cov duab nrog tshwj xeeb luam ntawv yuav tsum tau. Piv txwv li, yog tias tsuas yog ib lossis ob lossis peb xim tsuas yog siv rau hauv daim duab, kev siv ntau hom channel tuaj yeem txo tus nqi luam ntawv thiab xyuas kom meej qhov tseeb ntawm cov duab xim.

6. 8 ntsis / 16 ntsis channel hom

Hauv greyscale RGB lossis CMYK hom, 16-ntsis channel tuaj yeem siv los hloov lub neej ntawd 8- ntsis channels. Los ntawm lub neej ntawd, 8-ntsis channel muaj 256 qib. Yog hais tias tus naj npawb ntawm cov qib nce mus rau 16 cov khoom, cov qib ntawm txhua qhov channel yog 65,536, uas tuaj yeem tau txais cov xim ntau ntxiv. Photoshop tuaj yeem paub thiab nkag siab 16-ntsis channel duab, tab sis rau hom duab no muaj ntau qhov kev txwv, txhua cov ntxaij lim dej tsis tuaj yeem siv, thiab 16-ntsis channel hom duab tsis tuaj yeem luam tawm.

Rau, xim hom conversion

Yuav kom tso tawm cov duab kom raug nyob rau hauv ntau lub sijhawm, nws yog ib qho tsim nyog los hloov cov duab ntawm ib hom mus rau lwm qhov. Photoshop hloov pauv hom xim xav tau los ntawm kev ua tiav cov lus txib hauv "Image / Hom" submenu. Qhov kev hloov xim hom xim no tuaj yeem hloov pauv cov xim qhov tseem ceeb hauv daim duab mus tas li. Piv txwv li, thaum hloov RGB hom duab rau CMYK hom duab, RGB xim qhov tseem ceeb sab nraum CMYK gamut raug kho sab nraum CMYK gamut, yog li txo cov xim ntau yam.

Txij li qee cov xim poob qee cov ntaub ntawv xim tom qab hloov dua siab tshiab, nws yog ib lub tswv yim zoo kom khaws cov ntaub ntawv thaub qab rau lawv ua ntej hloov dua siab tshiab kom cov duab tuaj yeem rov qab yog tias tsim nyog.

1. Hloov cov duab xim rau hauv hom grey

Thaum hloov cov duab xim rau hom greyscale, Photoshop pov tseg tag nrho cov ntaub ntawv xim hauv cov duab qub, khaws tsuas yog qib greyscale ntawm cov pixels.

Grayscale hom tuaj yeem siv los ua hom nruab nrab rau kev hloov pauv ntawm hom bitmap thiab xim hom.

2. Hloov cov duab ntawm lwm hom rau hom bitmap

Hloov cov duab rau hom bitmap txo cov duab rau ob xim, uas ua kom yooj yim rau cov ntaub ntawv xim hauv daim duab thiab txo cov ntaub ntawv loj. Txhawm rau hloov cov duab rau hom bitmap, nws yuav tsum xub hloov mus rau hom greyscale. Qhov no tshem tawm cov xim thiab saturation cov ntaub ntawv los ntawm pixels, tawm tsuas yog tus nqi brightness. Txawm li cas los xij, txij li muaj qee qhov kev hloov kho tsawg heev muaj rau cov duab bitmap hom, nws yog qhov zoo tshaj plaws los kho cov duab hauv greyscale hom thiab tom qab ntawd hloov nws.

Bitmap hom dluab kho nyob rau hauv greyscale hom yuav saib txawv thaum hloov rov qab mus rau bitmap hom. Piv txwv li, pixels uas yog dub nyob rau hauv bitmap hom yuav tshwm grey thaum kho nyob rau hauv greyscale hom. Yog tias lub pixel ci txaus, nws yuav dhau los ua dawb thaum hloov rov qab mus rau hom bitmap.

3. Hloov lwm yam schemas rau index schemas

Thaum hloov cov duab xim rau ib qho xim xim, ntau cov xim ntawm cov duab raug tshem tawm thiab tsuas yog 256 ntawm lawv nyob, uas yog tus qauv ntawm cov xim uas txhawb nqa los ntawm ntau cov ntawv sau ua yeeb yaj kiab thiab cov nplooj ntawv web. Tsuas yog cov duab hauv greyscale thiab RGB hom tuaj yeem hloov mus rau indexed xim hom. Txij li thaum hom grey nws tus kheej yog tsim los ntawm 256 qib ntawm grey, tsis muaj qhov txawv txav ntawm cov xim lossis duab loj tom qab hloov mus rau qhov ntsuas xim. Txawm li cas los xij, tom qab RGB hom ntawm cov duab tau hloov mus rau qhov ntsuas xim hom, qhov loj ntawm daim duab yuav raug txo kom tsawg, thiab qhov pom kev zoo ntawm cov duab yuav raug puas tsuaj me ntsis.

4. Hloov cov duab RGB rau hauv hom CMYK

Yog tias hom RGB ntawm cov duab hloov mus rau hom CMYK, cov xim hauv daim duab yuav tsim cov xim sib cais, thiab xim gamut yuav raug txwv. Yog li ntawd, yog tias cov duab nyob hauv RGB hom, nws yog qhov zoo tshaj los hloov nws hauv RGB hom thiab tom qab ntawd hloov mus rau CMYK duab.

5. Siv Lab hom rau kev hloov pauv hom

Ntawm cov xim hom muaj nyob rau hauv Photoshop, Lab hom muaj qhov dav tshaj plaws gamut, suav nrog tag nrho cov xim hauv RGB thiab CMYK gamages. Yog li ntawd, tsis muaj xim poob thaum siv Lab hom rau kev hloov dua siab tshiab. Photoshop siv Lab hom ua hom kev hloov pauv sab hauv los ua kom tiav cov kev hloov pauv ntawm cov xim sib txawv. Piv txwv li, thaum hloov cov duab hauv RGB hom rau hom CMYK, lub khoos phis tawj yuav xub hloov RGB hom rau Lab hom, thiab tom qab ntawd hloov cov duab hauv Lab hom rau CMYK hom.

6. Hloov lwm hom rau ntau hom channel

Multi-channel hom tuaj yeem tau txais los ntawm kev hloov xim hom thiab tshem tawm cov xim qub channel ntawm daim duab.

Hloov CMYK dluab rau hauv ntau hom channel tsim cov xim xim uas muaj cyan, magenta, daj, thiab dub (cov xim xim yog cov xim tshwj xeeb premixed inks siv los hloov lossis ntxiv plaub xim luam ntawv inks; Spot xim channel yog xim tshwj xeeb rau kev ntxiv Saib ua ntej qhov chaw xim rau ib daim duab.

Hloov cov duab RGB rau hom multichannel tsim cov duab uas muaj cyan, magenta, thiab xim daj xim.

RGB, CMYK, lossis Lab duab cia li hloov cov duab mus rau ntau hom channel. Tus thawj channel yog hloov dua siab tshiab rau qhov chaw xim channel.
