Grayscale vs. Line Art

Mukupikisa, Mifananidzo yeGlack & White iri mumvuri we gray. Mukufungidzira kwemajeri idzi mifananidzo yeB & W inonzi grayscale kuti iviparadzanise kubva kune mutsvuku uye mutsvuku wemifananidzo.

Mifananidzo yeGrayscale inochengetedza mararamiro ehupamhi hwechiedza kupesana nemashoko ekuraira. Chimiro chechimiro chemajinga ndeye 256 shades ye grey kubva ku 0 (yakasviba) kusvika ku 255 (chichena).

Black & White Line Art inowanzo-2-ruvara (kazhinji yakasviba nemuchena) chikwangwani chepikicha, peni uye inki mifananidzo, kana mifananidzo yepencil. Kugadzirisa mifananidzo kuenderera mberi kwehupirwo (sezvinoratidzwa mumufananidzo) kunogona kuitwa nemigumisiro inokosha asi ine mapekisi esviki kana machena chete, tsanangudzo yemifananidzo yakarasika.

Paunenge uchichinja chinyorwa chemavara ku B & W, chifananidzo chemavara chinangwa.

RGB Images

Kunyange zvazvo zvichikwanisika kuongorora mufananidzo wemifananidzo mu grayscale kana kutora B & W digital photograph (pamwe nemamwe makamera) nokudaro kutamba chikamu chemuvara, nguva yakawanda yemifananidzo yatinoshanda nekutanga muvara.

Mavara akaiswa uye mifananidzo yemamera yekamera inowanikwa muRGB format. Kana zvisingaiti, inowanzowanzo tsika yekushandura kuRGB uye kushanda nemufananidzo (kugadziridza mune purogiramu yemapurogiramu software) mumutauro iwoyo. RGB mifananidzo mabhidhiyo ezvitsvuku, zvitsvuku, uye bhuruu zvinowanzoita mufananidzo wemuvara. Muvara woga woga wakagadzirwa nemhando dzakasiyana dzvuku, zvitubu, uye bhuruu.

Dzimwe nguva zvakakosha kana zvinodikanwa kudhinda kana kuratidza mifananidzo yeBlack & White (grayscale). Kana mufananidzo wepakutanga uri muvara, purogiramu yepurogiramu yepurogiramu yakadai seAdobe Photoshop kana Corel Photo-Paint inogona kushandiswa kushandura mufananidzo wechivara kune rumwe rudzi rwemuchena nemuchena.

Kune nzira dzakawanda dzekuwana B & W mifananidzo kubva mufananidzo wemuvara. Zvose zvine zvayo uye zvinoshandiswa uye zvinoshandiswa zvakanaka. Mhosva uye kukanganisa ndiyo ndiyo nzira yakanakisisa inoshandiswa. Nzira dzinoshandiswa kupfuura dzose dzinoshandisa "shandura ku grayscale" sarudzo kana kuti "deaturation" (kana kuti "bvisa mavara") sarudzo mumufananidzo wekugadzira software.

Shandura kuGreyyscale

Imwe yenzira dzakajeka uye dzinowanzobudirira zvikuru dzekuwana ruvara kubva mufananidzo wemuvara kuitenderera kuGreyys - chinhu chinowanzosangana mumifananidzo yekugadzira software. Kana uchinja RGB ruvara rwemuvara kuti uone girasi yacho yose inoshandurwa ne shades ye gray. Mufananidzo wacho haachiri muRGB.

Vanyori veInkjet vakaita saRGB kuitira kuti dzimwe nguva mugone kuwana zvinyorwa zvinyorwa zvinyorwa zvakanaka kana mukashandura chifananidzo kudzokera kuRGB mushure mokuenda kune greycale - ichichave chiri shades ye gray.

Desaturation (Bvisa Colors)

Imwe nzira yekuenda kubva mumarara kusvika mumvuri ye gray ndiyo kushatisa. Mune mamwe mapurogiramu ekugadzirisa zvifananidzo kune chekutsvaga kusarudzwa. Vamwe vanoidana kuti kubviswa kwemavara kana kuti zvinoda kuti iwe ushandise kutengesa kutora kuti uite izvi.

Kana iRGB inokosha yechifananidzo isati yakarongedzwa (marara akabviswa) maitiro ega ega akafanana kana kuti akadaro akafanana kune rumwe ruvara, zvichiita kuti tisapindira mumvuri mutema.

Kushatiswa kunokonzera Rudzi rweRweru, Rweru, uye rwebhuruu kusvika kune grey. Mufananidzo wacho uchiri muRGB colorspace asi mavara anochinja musoro. Kana kusvibiswa kwechigumisiro mufananidzo unoratidzika kuva girazi, hausi.

Grayscale vs. Kushatiswa uye Dzimwe Nzira dzokushandura

Panofungidzira, mifananidzo yakafanana yemufananidzo inoshandurwa ku grayscale uye yakarongedzwa kusvika mumvuri we grey ingangove yakaenzana. Mukuita, kusiyana kwepfungwa kunogona kuve pachena. Chimiro chemavara chinogona kunge chine rima uye chinogona kurasikirwa nezvimwe zvinyorwa zvichienzaniswa nemufananidzo mumwechete muzvinyorwa zvechokwadi.

Inogona kusiyana kubva pane imwe mufananidzo kuenda kune inotevera uye zvimwe zvingasiyana zvingasave pachena kusvikira mufananidzo wacho uchinyorwa. Chiedzo uye kukanganisa kungave ndiyo nzira yakanakisisa yekushandisa.

Zvimwe nzira dzekugadzira mufananidzo wechinhu chinobva pamufananidzo weruvara dzinosanganisira:

• Tendeuka kuLAB mamiriro uye ubudise chete chiteshi cheLuminance chekuda kwako nemuchena wako. Chigumisiro chakanaka zvakanyanya kufanana nemafungiro emagetsi.
• Bvisa imwe yemigwagwa yeRGB kana CMYK, uchishandisa imwe kana kubatanidza michina miviri kuti uwane zvaunoda.
• Panzvimbo pokubvisa zvose zvinyorwa zvakafanana nekushatisa, shandisa Hue / Saturation controls kuti dziratidze cheji imwe neimwe nekuda kwetsika.
• Gadzira monotone (rine rumwe ruvara kunze kweusiya) kana duotone yekuti-kwete-mavara, kwete-chaizvo madema uye machena.

Dhinda Mifananidzo yeGrayscale seGlack uye White Halftones

Kana yakadhindwa neinki yakasviba, chifananidzo chemavara chinotendeukira kune chimiro chemavara madema anokonzera toni dzinopfuurira dzechifananidzo chepakutanga. Mvura yakadzika ye grey inosanganisira maduku mashoma kana maduku madema akaiswa kure. Mdima wakajeka we grey unowedzera kana kuti mahwendefa madema madota ane pedyo.

Saka, pakudhinda mufananidzo we grayscale neinki inopinza iwe unonyanya kudhinda B & W mifananidzo nekuti halftone inongova madota madota einki.

Iwe unogona kubudisa halftones yedijitori inotungamira kubva pane software kusvika kune printer. Izvozvo zvinogadziriswa zvinoshandiswa zvingave zvichitsanangurwa muma printers yako PPD (PostScript Printer Driver) kana kuiswa zvakananga mune software yako program.

Paunenge uchidhinda mapikicha eB & W kune inkjet printer, mhinduro inogona kuve yakasiyana nekudhindwa neinki yega kana kuti kubvumira kuti printer ishandise mavara inks kudhinda shades ye gray. Mirazi inoshanduka - kubva pane zvisingakwanisi kuoneka - inogona kuitika kana uchishandisa mavara inks. Zvisinei, inki yakasviba inogona kurasikirwa mamwe emashoko akaisvonaka uye inoita kuti zviratidzo zvakajeka zveinki-imwe gare inotaridzika.

Nezvokudhinda mabhizimusi, siya mavara emagetsi mumagetsi ekutenda kunze kwekunge mupi wepurogiramu wenyu anopa mazano. Zvichienderana netsika yekudhinda, dema uye nyeupe halftone zvikwangwani zvinotonhora kupfuura izvo mamwe ma printer printer angakwanisa kuita. Zvisinei, iwe unokwanisa kutsanangura yako zvidzidzo muofaira yako kana iwe uchida (kana kuti ugadzirise zvakanakira).

Ona " Zvinyorwa zvemuvara nemashizha emachena nemachena " pane zvakawanda pakushanda ne halftones.
