GIMP inopa nzira dzakawanda dzekushandura mifananidzo kuita dema nechena. Imwe neimwe sarudzo inosiyana nematanho akasiyana ekuchinja uye mhedzisiro dzakasiyana zvakare. Hedzino nzira dzese dzaungashandisa kushandura mifananidzo uye mutsauko pakati pavo. Kusarudza imwe pane imwe ingori nyaya yekuda sekuda kwako.
Shandura mafoto kuita dema uye chena paGIMP
Ngatitangei nezviri nyore zveboka.
1. Gonesa greyscale mode
Nekumisikidza, chifananidzo chinovhura muRGB modhi, asi kushandura iyo modhi kuita greyscale inongochinja mufananidzo kuita dema uye chena. Iine greyscale, sekureva kunoita zita, iwe hauna humwe hutongi hwechifananidzo nekuti inoshandura color scheme yemufananidzo zvakananga. Iwe haugone kudzora kusimba kana matani emavara zvakare. Zvakare, hapana sarudzo yekuseta iyi kune imwe chete layer. Kana yangogoneswa, ichaiswa kumufananidzo wese pamwe chete nematanho ese.
Kuti uchinje mufananidzo kuti uve dema nechena uchishandisa greyscale, tinya Mufananidzo > Modhi uye sarudza Radio Grayscale.
Izvi zvinoshandura mufananidzo kuti uve dema uye chena ipapo ipapo.
Ne grayscale yakasarudzwa, zvese zvinotevera zvinopinza uye edits zvichave zvakare greyscale. Kuti uchinje izvi, zvakare, vhura Mufananidzo > Modhi uye sarudza RGB . Izvi zvinoburitsa mavara pasina kushandura mufananidzo wawakashandura kuita greyscale.
2. Shandisa desaturation
Kusiyana neiyo greyscale nzira, ine desaturation, unogona kusarudza kusimba kweiyo nhema uye chena mufananidzo waunoda. Izvi zvinoreva kuti iwe une sarudzo yekusashandura chifananidzo kuita dema uye chena kana uchida.
Kuti uchinje mufananidzo kuita dema uye chena uchishandisa Desaturation, sarudza iyo layer yaunoda kushandura kuita nhema nechena. Iwe zvakare une sarudzo yekusarudza akawanda akaturikidzana nekudzvanya ctrl bhatani.
Kana yangosarudzwa, tinya Option ruvara mune menyu bar uye wobva wasarudza saturation .
Izvi zvinovhura popup kwaunogona kushandura kusimba kwemavara matema uye machena mimvuri uchishandisa iyo . Scale .
Ichi chishandiso chinochengetedza iyo saturation level seyakagadzirirwa izvo zvinoreva kuti ichashandisa zvimiro zvakafanana zvemimwe mifananidzo gare gare. Kunze kweizvozvo, kune mamwe ma desaturation modes senge Luminance, Luma, Lightness, Avhareji و ukoshi . Imwe neimwe nzira inoshandisa mumvuri wakasiyana wemutema uye chena kumufananidzo unogona kugadziridzwa zvakare nekuchinja kupenya uye mavara machane. Iwe unogona kuwana idzi modes nekuvhura Colors> desaturate wobva wasarudza desaturate zvakare .
Izvi zvinovhura popup kwaunogona kushandisa aya modhi kumufananidzo.
Panzvimbo pekuvimba nechishandiso chekupa akasiyana modhi yegreyscale, iwe unogona kugadzirisa nemaoko maRGB chiteshi kuti uwane chaiyo dema nechena yaunoda.
3. Kugadzirisa kuburikidza neChannel Mixer
NeChannel Mixer sarudzo, unogona kugadzirisa chikamu chese chemufananidzo. Iwe unogona kusarudza iwo dzvuku, girinhi, uye bhuruu mazinga emufananidzo kuti uwane yakakwana dema uye chena ruvara rwauri kutsvaga.
Kuti uchinje mavara kuita dema nechena nemusanganisi wechiteshi, vhura Colors> Zvikamu> Mono Mixer. Izvi zvinoshandura mufananidzo kuita dema uye chena uye kuvhura hwindo repopup rekugadzirisa RGB chiteshi.
Iwe unogona ikozvino kutamba neaya maRGB chiteshi kushandura toni yeruvara rwemufananidzo wakasviba nechena. Kuti uchengetedze mwero wakafanana wekupenya, unofanirwa kuwedzera kukosha kusvika ku100%. Semuenzaniso, kana iwe ukaisa tsvuku kusvika 31%, yegirini kusvika 58%, uye yebhuruu kusvika 11%, iwe unowana imwecheteyo nhema uye chena mufananidzo sepagreyscale sarudzo. Kuti udzivise nyaya yekupenya iyi, unogona kugonesa bhatani reKeep Bright. Iyo inogadzirisa iyo RGB maseru pasina kukanganisa mazinga ekupenya.
Heino muenzaniso. Kana uchitsvaga denga rakasviba, dzikisa mwero wegwara reblue zvinoita kuti denga riratidzike kusviba. Unogona kushandisa nzira iyi kushandura mavara echiteshi kuburitsa zvimwe zvinhu.
Iyo mukana weChannel Mixer ndeyekuchinjika. Kwandiri, ndezvekuwedzera mamwe mutsauko uye kuburitsa iyo yakakwana dhizaini uye mitsara mumifananidzo pasina kuwedzera ruzha.

Iyo greyscale sarudzo yakanakira kushandura mifananidzo kuita nhema uye chena asi inoshaya kudzora iyo kusimba uye sarudzo dzechiteshi zvinopa paunenge uchigadzirisa mufananidzo. Kudzikisa mazinga ekuzara kunobatsira kugadzirisa kusimba, asi yekupedzisira nhema uye chena mufananidzo une ruzha rwakati wandei kana uchienzaniswa negreyscale kamwe kana yaswededzwa mukati. Iyo nzira yekusanganisa chiteshi inobvumira kugadzirisa mufananidzo kuti uenderane nezvido zvako. Iwe unogona kudzora ruvara rwemunhu, uye saka iwe unogona kuita zvinhu sekushandura denga kuve rakasviba ruvara, kana kuburitsa chimwe chinhu chine mumvuri wakajeka, nezvimwe.
