Kodi mungakonze bwanji banding mu GIMP?

Mdziko lapansi Muzojambula zojambula, imodzi mwazovuta zomwe timakumana nazo ndizotchedwa "Banding". Mawuwa amatanthauza mizere kapena magulu omwe amaganiziridwa mu chithunzi chimodzi pamene ma gradients amtundu sali osalala mokwanira. Izi zitha kukhala zokwiyitsa makamaka tikamagwira ntchito yosindikiza, chifukwa zitha kukhudza kwambiri zotsatira zomaliza. Ngati mugwiritsa ntchito GIMP Monga pulogalamu yosinthira zithunzi, mudzakhala okondwa kudziwa kuti pali njira zosiyanasiyana zowongolera vuto ili. Ndikoyenera kutchula kuti ichi chikhala chiwongolero chaukadaulo cholunjika kwa iwo omwe akudziwa kale pulogalamu iyi.

Nkhaniyi ifotokoza kwambiri Momwe mungakonzere Banding mu GIMP?, vuto loyenera makamaka kwa opanga digito ndi ojambula. Tisanthula vutoli, ndikukuwonetsani momwe mungalizindikirire, ndipo koposa zonse, momwe mungalikonzere mu GIMP. Ngati mwakhala mukukumana ndi vutoli kwakanthawi, kapena mukungofuna kuphunzira zambiri za kasamalidwe kazithunzi mu pulogalamuyi, nkhaniyi ndi yanu. Komanso, ngati mukufuna kulowa mozama momwe mungapindulire ndi GIMP, mutha kufunsa njira zathu zabwino zogwiritsira ntchito GIMP moyenera.

Kumvetsetsa Vuto la Banding mu GIMP

Vuto la banding Ndizovuta kwambiri mu GIMP zomwe zimakhala ndi mawonekedwe a magulu kapena mikwingwirima pakusintha kwamtundu wosalala pazithunzi zathu. Kubwereraku kumayamba chifukwa cha kuchepa kwakuya pang'ono kwa zithunzi, zomwe zimachepetsa kuchuluka kwa mitundu yomwe ilipo kuti iwonetse chithunzicho. Kumanga kumawonekera mowoneka bwino mumitundu yosalala kuchokera kumtundu umodzi kupita ku umzake, ndikupanga "masitepe" osati kusintha kosalala.

Pali njira zingapo zothetsera vutoli, njira yabwino yothetsera vutoli kuchepetsa banding pogwiritsa ntchito njira ya dithering. Njirayi imaphatikizapo kuwonjezera phokoso lachisawawa pachithunzichi, zomwe zingathandize kubisala banding. Dithering ingawoneke ngati yosagwirizana chifukwa nthawi zambiri imagwirizana ndi kuchepetsa mtundu wazithunzi. Komabe, mu nkhaniyi, zimathandiza kupititsa patsogolo chinyengo cha kusintha kwamtundu wosalala. Kuti mugwiritse ntchito njirayi mu GIMP tsatirani izi:

• Tsegulani chithunzi chojambulidwa mu GIMP.
• Pitani ku Zosefera menyu ndikusankha Noise njira.
• Sankhani "Blur" njira ndikusintha mulingo wa zotsatira kuti mupeze zotsatira zomwe mukufuna.

Pomaliza, ndikofunikira kuti mugwire ntchito mozama kwambiri momwe mungathere. Izi zikutanthauza kuti muyenera kuyesa kugwiritsa ntchito zithunzi za 16-bit kapena ngakhale Ma bits 32 m'malo mogwira ntchito ndi zithunzi za 8-bit. Cholinga apa ndi kukhala ndi mitundu yambiri yogwiritsira ntchito komanso kuchepetsa maonekedwe a banding. Buku lathu la kufunikira kwa kuya kwa utoto mu GIMP imapereka kusanthula mozama momwe muyenera kuchitira komanso chifukwa chake. Kumbukirani zimenezo kumtunda kwakuya kwa chithunzicho, kumachepetsa mwayi wokumana ndi banding.

Njira Zodziwira Magulu Azithunzi Anu

Gawo loyamba kuzindikira banding mu zithunzi zanu ndiko kumvetsa kwenikweni chimene icho chiri. Banding ndi mawu zomwe zimagwiritsidwa ntchito kufotokoza ndondomeko ya mizere yowonekera kapena magulu omwe angawonekere pachithunzi. Nthawi zambiri zimachitika chifukwa cha kuchepa kwa mitundu pa kamera kapena polojekiti. Mwa kuyankhula kwina, zimachitika pamene pali kusintha kosalala kwa mtundu mu fano, koma chipangizocho sichingathe kuimira molondola. Mwakuchita, mutha kuwona izi pomwe chithunzi chili ndi madera osalala, monga thambo losawoneka kapena maziko.

Gawo lachiwiri ndikuwunika ma banding muzithunzi zanu. Mukamvetsetsa zomwe banding ikuchitika, muyenera kuyang'ana zithunzi zanu. Yang'anirani madera a chithunzicho ndi kusintha kwamtundu wosalala ndikuyang'ana mawonekedwe owoneka a mabanki akupanga. Mungathe kuchita tsegulani kuti muwone zambiri. Njira iyi Zingakhale zovuta pang'ono, makamaka ngati chithunzicho chili ndi mitundu yambiri kapena matani. Komabe, phunzirani kuzindikira banding adzakulolani kuti mukonze moyenera mu pulogalamu yosinthira zithunzi ngati GIMP.

Pomaliza, Ndikofunika kumvetsetsa kuti kuwongolera kwa banding sikutheka nthawi zonse. Nthawi zina mtundu wamtundu wa kamera kapena wowunikira umakhala wocheperako ndipo sungathe kuyimira mithunzi ina. Pazifukwa izi, kupatsirana kungakhale kosapeŵeka. Nthawi zina, bandeji imatha kukhala chifukwa cha mawonekedwe osawoneka bwino kapena mawonekedwe a kamera. Pazifukwa izi, pangafunike kuwongolera mawonekedwe azithunzi kapena kusintha makonda. Mwachidule, kutha kuzindikira ndi kukonza bandeji kumadalira kwambiri mtundu wa zithunzi komanso kumvetsetsa kwaukadaulo.

Njira Yogwira Ntchito Yowongolera Banding mu GIMP

Kukonza banding mu GIMP kungakhale njira yovuta ngati simukudziwa njira yoyenera. Izi nthawi zambiri zimawonekera mu gradients ndipo zimasokoneza kusalala kwa kusintha kwa mtundu. Nkhani yabwino ndiyakuti pali mayankho ogwira mtima omwe mungagwiritse ntchito pogwiritsa ntchito GIMP. Choyamba, mutha kugwiritsa ntchito chida cha "Decomposition" chomwe chili mumenyu ya "Colours".

Chotsani chithunzicho kukhala zigawo zake zamtundu amalola mwatsatanetsatane bandi kukonza. Mukasankha "Kuwola," sankhani "RGB" kapena "HSV," kutengera chithunzi chomwe mukugwira nacho. Kenako zenera latsopano lidzatsegulidwa ndi zigawo zitatu zamitundu. Maguluwa nthawi zambiri amawonekera kwambiri pagawo lowala, koma mungafunike kugwiranso ntchito zina ziwirizo. Gwiritsani ntchito chida cha "Levels" kapena "Curves" kuti muzitha kusintha.

Pomaliza, ndikofunikira kuwunikira kuti iyi si njira yokhayo yokha, koma Nthawi zonse kumbukirani kugwira ntchito ndi mtundu wamtundu womwe ungatheke kuti mupewe zotsatira za banding. Mawonekedwe a 8-bit nthawi zambiri ndi omwe amayambitsa vutoli, kotero ngati mutha kugwira ntchito ndi zithunzi za 16-bit, mutha kuchepetsa mwayi womanga. Ngati mukufuna zambiri zamomwe mungakonzere ena zolakwika zofala mu GIMP, mutha kuwona nkhani yathu momwe mungakonzere zolakwika zomwe wamba mu GIMP. Ndi kuleza mtima komanso kuchita, mutha kukonza bwino ma bandeji pazithunzi zanu ndi GIMP.

Zochita Zabwino ndi Malangizo mukamagwira ntchito ndi Banding mu GIMP

Kuti muthane ndi vuto la ma banding mu GIMP, ndikofunikira kudziwa kusintha kwa mulingo, njira zotsutsana ndi alias, ndi kuya pang'ono. Mwa kusintha miyeso ya kuwala mu fano lanu, mukhoza kuchepetsa "cutoff" yovuta pakati pa kuwala ndi mthunzi, motero kuchepetsa maonekedwe a banding. Kuti muchite izi, pitani ku Colours> Milingo ndikusintha zolowetsa ndi zotulutsa mpaka kusintha kwa ma toni kumakhala kosalala. N'zothekanso kugwiritsa ntchito kusanjikiza kosalala kuti mubise banding yoonekera kwambiri. Ngakhale sizimathetsa vuto, zimatha kukhala zothandiza nthawi zina, makamaka ngati nthawi ndiyomwe imatsimikizira. Kuti mugwiritse ntchito, ingopangani gawo latsopano ndikusankha Zosefera> Blur> Smooth.

Gwiritsani ntchito mozama pang'ono Zimathandizira kusintha pakati pa ma toni ochulukirapo, potero kumachepetsa banding. Nthawi zambiri, kugwira ntchito ndi kuya kwa 16 bits m'malo mwa 8 kumatha kupititsa patsogolo khalidwe la gradient. Kuti mugwiritse ntchito zosinthazi, pitani ku Image> Mode> Convert to Spot Color (16-bit), ndikusankha Lolani kusintha kwamitundu kuti mutsegule zosintha.

Kumvetsetsa ndi kugwiritsa ntchito njirazi moyenera kumafuna kuchita ndi kuyesa. Kumbukirani, ndikofunikira kuti muwunikenso zithunzi zanu pafupipafupi kuti muwone zovuta zomwe zitha kuwoneka. Kuti mudziwe zambiri za njira zapamwamba zosinthira zithunzi mu GIMP, tikukupemphani kuti muwone malangizo athu. momwe mungasinthire zithunzi mu GIMP. Palibe yankho lofanana ndi limodzi, kotero tikukulimbikitsani kuti mufufuze njira zosiyanasiyana mpaka mutapeza zomwe zikugwirizana ndi kalembedwe ndi zosowa zanu.
