Girasiyo vs. Mzere wa Art

Kujambula, zithunzi zakuda ndi zoyera kwenikweni zimakhala zofiira. Mujambula chithunzichi zithunzi za B & W zimatchedwa grayscale kuti ziwasiyanitse ndizojambula zakuda ndi zoyera.

Zithunzi zojambulidwa zimasungira zamtengo wapatali kuti zikhale zowala mosiyana ndi zamtundu. Chithunzi chojambulidwa ndi masentimita 256 of gray kuchokera ku 0 (chakuda) kufika 255 (choyera).

Black & White Line Zojambulazo zimakhala zobiriwira (kawirikawiri zakuda ndi zoyera) zojambulajambula, zolembera ndi zojambula, kapena zojambula za pensulo. Kutembenuza chithunzi chojambula zithunzi (monga momwe tawonera mu fanizo) kukhoza kupangidwira zotsatira zapadera koma ndi pixelisi zakuda kapena zoyera, tsatanetsatane wa zithunzi zatayika.

Pamene mutembenuza chithunzi cha mtundu wa B & W, chithunzithunzi cha galasi ndilo cholinga.

Zithunzi za RGB

Ngakhale kuti n'zotheka kuwonetsa fano lajambula pamoto kapena kutenga B & W kujambula chithunzi (ndi makamera ena) motero kudumpha masitepe, zithunzi zambiri zomwe timagwira ndi kuyamba kwa mtundu.

Zithunzi zojambulajambula ndi zithunzi za kamera zam'jambula zimakhala mu mtundu wa RGB. Ngati sichoncho, kawirikawiri ndi mwambo kuti mutembenuzire ku RGB ndikugwira ntchito ndi chithunzi (kusintha mu pulogalamu ya mapulogalamu a zithunzi) mumtundu umenewo. Zithunzi za RGB zamasitolo zosungira zofiira, zobiriwira, ndi buluu zomwe nthawi zambiri zimapanga fano la mtundu. Mtundu uliwonse umapangidwa ndi zofiira, zobiriwira, ndi zamtundu wosiyanasiyana.

Nthawi zina ndizofunika kapena zofunikira kusindikiza kapena kusonyeza zithunzi za Black & White (grayscale). Ngati chithunzi choyambirira chiri ndi mtundu, pulogalamu yamakono yojambula zithunzi monga Adobe Photoshop kapena Corel Photo-Paint ingagwiritsidwe ntchito kusinthira fano la mtundu wina mwa mtundu wina wakuda ndi woyera.

Pali njira zingapo zopezera chithunzi cha B & W kuchokera ku chithunzi cha mtundu uliwonse. Zonse zili ndi ubwino ndi zowonongeka zomwe zimagwiritsidwa ntchito. Njira ndi zolakwika ndizo njira yabwino kwambiri. Njira zomwe amagwiritsa ntchito kwambiri zimagwiritsa ntchito "kutembenuza ku" greycale "kapena" deaturation "(kapena" chotsani mtundu ") muzithunzi zojambulajambula.

Sinthani ku Grayscale

Imodzi mwa njira zosavuta komanso zowoneka bwino zopezera mtundu wa chithunzi ndikutembenuza ku Grayscale - njira yowonongeka pulogalamu yokonza zithunzi. Pamene mutembenuza chithunzi cha RGB kuti muwone mtundu wonse umasinthidwa ndi mithunzi ya imvi. Chithunzicho sichithanso ku RGB.

Makina osindikizira a Inkjet ngati RGB kotero kuti nthawi zina mukhoza kukwaniritsa zotsatira zowonjezera ngati mutatembenuza fanolo kubwerera ku RGB mutatha kupita kumsika - idzakhala yamithunzi yofiira.

Kusambitsidwa (Chotsani Colours)

Njira ina yopitilira kuchoka ku mtundu kupita kumthunzi wa imvi ndiyo kutayika. Mu mapulogalamu ena okonzekera mafano pali kusankha kosasintha. Ena amachitcha kuti kuchotsa mtundu kapena amafuna kuti mugwiritse ntchito mphamvu zowonjezera kuti mukwaniritse izi.

Ngati chiwerengero cha RGB cha fano ndi desaturated (mtundu wachotsedwa) zikhalidwe za aliyense zili zofanana kapena zofanana ndi mtundu uliwonse, zomwe zimapangitsa kuti mthunzi wautsi umalowerera.

Kusakaniza kumaponyera mazira a Red, Green, ndi Blue kupita ku imvi. Chithunzicho chidalibe mu RGB colorpace koma mitundu imakhala imvi.Pamene kusokoneza zotsatira mu chithunzi chomwe chikuwonekera kukhala chokhazikika, sichoncho.

Zojambulajambula motsutsana ndi Kuyeretsa ndi Njira Zina Zosinthira

Mwachidziwitso, fano lomwelo limatembenuzidwa kuti likhale lachitsulo ndipo limasinthidwa kukhala mithunzi ya imvi lingakhale lofanana. Mwachizoloŵezi, kusiyana kosaonekera kungakhale koonekera. Chithunzi chowonetsedwa chikhoza kukhala chakuda pang'ono ndipo chingathe kutaya tsatanetsatane wina poyerekeza ndi chithunzi chomwecho mu galasi yeniyeni.

Zingasinthe kuchokera pa chithunzi chimodzi kupita kutsogolo ndipo kusiyana kwake sikungakhale koonekera mpaka fanolo lisindikizidwa. Mayesero ndi zolakwika zingakhale njira yabwino kwambiri yogwiritsira ntchito.

Njira zina zopangira chithunzithunzi kuchokera ku fano la zithunzi zikuphatikizapo:

• Sinthani njira ya LAB ndikuchotsani chingwe cha Luminance chanu chakuda ndi zoyera. Zotsatira ndizofanana ndi mafilimu.
• Pezani imodzi mwa njira za RGB kapena CMYK, pogwiritsa ntchito imodzi kapena kuphatikiza njira zingapo kuti mupeze zomwe mukufuna.
• M'malo mochotsa mtundu wogawanika ndi kutayirira, gwiritsani ntchito maulamuliro / Kukhazikitsa kuti asinthe njira iliyonse pamtundu uliwonse.
• Pangani monotone (ndi mtundu wina wosiyana ndi wakuda) kapena duotone ya mtundu wosaoneka, osati-kwenikweni wakuda ndi woyera.

Sindizani Zithunzi Zogulitsa Monga Black ndi White Halftones

Pakasindikizidwa ndi inki yakuda, chithunzi choyipa chimatembenuzidwa ku ndondomeko ya madontho wakuda omwe amafanana ndi maimidwe opitiriza a chithunzi choyambirira. Mithunzi yofiirira imakhala ndi madontho odawa ochepa kapena ochepa omwe amakhala osiyana kwambiri. Mdima wamdima wakuda uli ndi madontho akuluakulu kapena akuluakulu akuda ndi malo ozungulira.

Choncho, mukasindikiza chithunzi chojambulidwa ndi inkino wakuda mumasindikizira chithunzi cha B & W chifukwa chakuti halftone ndi madontho wakuda a inki.

Mungathe kupanga ma-halftones opangidwa kuchokera ku mapulogalamu kupita ku osindikiza. Zotsatira za halftone zomwe zimagwiritsidwa ntchito zingathe kutchulidwa mu makina anu osindikiza PPD (PostScript Printer Driver) kapena kukhazikitsidwa mwadongosolo la pulogalamu yanu.

Pamene mukujambula zithunzi za B & W ku printer inkjet, zotsatira zingakhale zosiyana ndi kusindikiza ndi inkino yakuda kokha kapena kulola wosindikiza kugwiritsa ntchito inks za mtundu kuti asindikize shades of gray. Kusintha kwa maonekedwe - kuchokera ponyalanyaza kuonekera - kungakhalepo pogwiritsa ntchito inks za mtundu. Komabe, inki yakuda imatha kutaya zina mwazomwe zimakhala bwino ndipo zimakhala ndi madontho oonekera kwambiri a inki - nthawi yowonekeratu.

Kuti muzisindikiza zamalonda, chotsani zithunzi zowonongeka muzolowera zamagetsi pokhapokha ngati wothandizira wanu akuwonetsera zina. Malingana ndi njira yosindikizira, zojambula zakuda ndi zoyera zimakhala zosavuta kuposa zomwe ena osindikizira mabuku angathe kuzigwiritsa ntchito. Komabe, mukhoza kufotokozera zojambula zanu mumapulogalamu anu ngati mukufuna (kapena kuti mupange zotsatira zapadera).

Onaninso " Zowonjezera zamitundu ndi zitsamba zamdima ndi zoyera " zambiri pogwira ntchito ndi halftones.
