GIMP imapereka njira zingapo zosinthira zithunzi kukhala zakuda ndi zoyera. Chisankho chilichonse chimasiyanasiyana ndi magawo osiyanasiyana osinthika komanso zotsatira zosiyanasiyana. Nazi njira zonse zomwe mungagwiritse ntchito kutembenuza zithunzi ndi kusiyana pakati pawo. Kusankha chimodzi pa chimzake ndi nkhani yongokonda malinga ndi zosowa zanu.
Sinthani zithunzi kukhala zakuda ndi zoyera pa GIMP
Tiyeni tiyambe ndi zosavuta za gululo.
1. Yambitsani mawonekedwe a grayscale
Mwachikhazikitso, chithunzicho chidzatsegulidwa mu RGB mode, koma kusintha mawonekedwe kukhala grayscale kudzasintha chithunzicho kukhala chakuda ndi choyera. Ndi grayscale, monga momwe dzinalo likusonyezera, mulibe mphamvu zowonjezera pa chithunzicho chifukwa chimasintha mtundu wa chithunzichi mwachindunji. Simungathe kulamulira mphamvu kapena njira zamitundu. Komanso, palibe mwayi woyika izi kukhala wosanjikiza umodzi wokha. Mukayatsa, idzagwiritsidwa ntchito pa chithunzi chonse pamodzi ndi zigawo zonse.
Kuti musinthe chithunzicho kukhala chakuda ndi choyera pogwiritsa ntchito grayscale, dinani Chithunzi> Mode ndi kusankha Radio Grayscale.
Izi zisintha chithunzicho kukhala chakuda ndi choyera nthawi yomweyo.
Ndi grayscale yosankhidwa, zolowa zonse zotsatila ndi zosintha zidzakhalanso zotuwa. Kusintha izi, kachiwiri, tsegulani Chithunzi> Mode ndi kusankha RGB . Izi zidzatulutsanso mitunduyo popanda kusintha chithunzi chomwe mwasintha kukhala grayscale.
2. Gwiritsani ntchito desaturation
Mosiyana ndi njira ya grayscale, ndi desaturation, mutha kusankha kukula kwa chithunzi chakuda ndi choyera chomwe mukufuna. Izi zikutanthauza kuti muli ndi mwayi wosasintha chithunzicho kukhala chakuda ndi choyera ngati mukufuna.
Kuti musinthe chithunzicho kukhala chakuda ndi choyera pogwiritsa ntchito Desaturation, sankhani wosanjikiza womwe mukufuna kusintha kukhala wakuda ndi woyera. Mulinso ndi mwayi kusankha angapo zigawo ndi kukanikiza ctrl batani.
Mukasankha, dinani Option mtundu mu kapamwamba menyu ndiyeno kusankha kuchuluka .
Izi zidzatsegula popup momwe mungasinthire kukula kwa mithunzi yakuda ndi yoyera pogwiritsa ntchito . Scale .
Chida ichi chidzapulumutsa machulukitsidwe mlingo monga preset kutanthauza kuti ntchito zoikamo chimodzimodzi zithunzi zina pambuyo pake. Kupatula apo, pali njira zina za desaturation monga Luminance, Luma, Lightness, Average و mtengo . Mtundu uliwonse umagwiritsa ntchito mthunzi wosiyana wakuda ndi woyera ku chithunzi chomwe chingasinthidwe mowonjezereka mwa kusintha kuwala ndi njira zamtundu. Mutha kupeza mitundu iyi potsegula Colours> zowononga ndiye sankhani Kutaya kenanso .
Izi zidzatsegula mphukira pomwe mungagwiritse ntchito mitundu iyi pazithunzi.
M'malo modalira chida chopereka mitundu yosiyanasiyana ya grayscale, mutha kusintha pamanja njira za RGB kuti mupeze zakuda ndi zoyera zomwe mukufuna.
3. Kusintha kudzera pa Channel Mixer
Ndi njira ya Channel Mixer, mutha kusintha gawo lililonse lachithunzicho. Mutha kusankha milingo yofiira, yobiriwira, ndi yabuluu pachithunzichi kuti mupeze mtundu wakuda ndi woyera womwe mukuyang'ana.
Kuti musinthe mitundu kukhala yakuda ndi yoyera ndi chosakanizira chanjira, tsegulani Mitundu> Zigawo> Mono Mixer. Izi zisintha chithunzicho kukhala chakuda ndi choyera ndikutsegula zenera la popup kuti musinthe makonda a RGB.
Tsopano mutha kusewera ndi ma RGB awa kuti musinthe kamvekedwe kazithunzi zakuda ndi zoyera. Kuti musunge mulingo womwewo wa kuwala, muyenera kuwonjezera zomwe zili mpaka 100%. Mwachitsanzo, ngati muyika zofiira ku 31%, zobiriwira mpaka 58%, ndi buluu mpaka 11%, mudzapeza chithunzi chofanana chakuda ndi choyera monga munjira ya grayscale. Kuti mupewe vuto lowalali, mutha kuloleza batani la Keep Bright. Idzasintha zigawo za RGB popanda kukhudza milingo yowala.
Nachi chitsanzo. Ngati mukuyang'ana thambo lakuda, tsitsani njira ya buluu yomwe ingapangitse thambo kuoneka lakuda. Mutha kugwiritsa ntchito njirayi kuti musinthe mitundu yamakanema kuti mutulutse zinthu zina.
Ubwino wa Channel Mixer ndikusinthasintha. Kwa ine, zonse zimangowonjezera kusiyanitsa ndi kutulutsa mawonekedwe abwino ndi mizere muzithunzi popanda phokoso.
Convolution: Sinthani zithunzi zakuda ndi zoyera ndi GIMP
Njira ya grayscale ndiyabwino kutembenuza zithunzi kukhala zakuda ndi zoyera koma ilibe mphamvu kuti mphamvu ndi zosankha zanjira zimapereka posintha chithunzicho. Kuchepetsa machulukitsidwe kumathandiza kusintha kukula kwake, koma chithunzi chomaliza chakuda ndi choyera chimakhala ndi phokoso lochulukirapo poyerekeza ndi greyscale kamodzi mukalowetsamo. Njira yosakanikirana ndi njira imalola kusintha chithunzicho kuti chigwirizane ndi zosowa zanu. Mutha kuwongolera mtundu wamunthu, kotero mutha kuchita zinthu monga kutembenuza thambo kukhala lakuda, kapena kutulutsa china chake chokhala ndi mthunzi wowoneka bwino, ndi zina zambiri.
