Indlela yokuguqula isithombe ku-Black and White ku-GIMP
Kukhona indlela engaphezu kweyodwa yokuguqula isithombe kumnyama nomhlophe ku- GIMP futhi okukhethayo kuyoba yindaba yokuzikhethela kanye nokuthanda kwakho. Kungase kubonakale kuyamangaza ukuzwa ukuthi amasu ahlukahlukene akhiqiza imiphumela ehlukene, noma kunjalo, kunjalo. Ngalokhu engqondweni, ngizokubonisa ukuthi ungasebenzisa kanjani isici se- Channel Mixer ukuze ukhiqize izithombe eziningi ezimnyama nezamhlophe ku-GIMP.
Ngaphambi kokucubungula i- Channel Mixer , ake sibheke indlela elula yokuguqula isithombe sedijithali kumnyama nomhlophe ku-GIMP. Ngokuvamile uma umsebenzisi we-GIMP efuna ukuguqula isithombe sedijithali kumnyama nomhlophe, bazoya kwimenyu ye- Colours bese ukhetha Desaturate . Ngenkathi ingxoxo yeDesaturate inikeza izinketho ezintathu zendlela ukuguqulwa kuzokwenziwa ngayo, okuwukuthi ukukhanya , ukukhanya nokukhanya kwalababili, ngokwenza umehluko ngokuvamile uvame kakhulu.
Ukukhanya kukhiwa ngemibala ehlukene futhi ukulinganisa kwemibala ehlukene kuzovame ukuhluka endaweni kuya endaweni engaphakathi kwesithombe se-digital. Uma usebenzisa ithuluzi le- Desaturate , imibala ehlukene eyenza ukukhanya iphathwa ngokulinganayo.
I- Channel Mixer , noma kunjalo, ikuvumela ukuba uphathe ukukhanya okubomvu, okuluhlaza okwesibhakabhaka nokuhlaza okwesibhakabhaka ngokuhlukile kwesithombe okusho ukuthi ukuguqulwa kokugcina okumnyama nokumhlophe kungabonakala kuhluke kakhulu kuncike kumzila wesigcawu.
Kubasebenzisi abaningi, imiphumela yeThuluzi le- Desaturate iyamukeleka ngokuphelele, kodwa uma ufuna ukuthatha ukulawula okuningi kokudala phezu kwezithombe zakho zedijithali, khona-ke funda.

Isixhumanisi se-Channel Mixer
Ingxoxo ye- Channel Mixer ibonakala ifihliwe ngaphakathi kwemenyu ye- Colors , kodwa uma uqala ukuyisebenzisa Ngiyaqiniseka ukuthi uzohlala njalo lapho uguqula isithombe sedijithali kumnyama nomhlophe ku-GIMP.
Okokuqala, kuzodingeka uvule isithombe ongathanda ukuguqula ku-mono, ngakho iya kufayela > Vula bese uhamba uye esithombeni sakho esikhethiwe bese uvula.
Manje ungaya ku- Colors > Components > Isiteshi se-Channel ukuvula ingxoxo ye- Channel Mixer . Ngaphambi kokusebenzisa ithuluzi le- Channel Mixer , ake simane futhi sibheke ngokushesha izilawuli. Ngenxa yokuthi sisebenzisa leli thuluzi ukuguqula isithombe sedijithali sibe mnyama nomhlophe, singasinaki imenyu yokudonsa isiteshi sokukhipha njengoba lokhu kungenayo impumelelo kokuguqulwa kwe-mono.
I-box ye- Monochrome ibhokisi izoguqula isithombe sibe mnyama nomhlophe futhi uma lokhu kukhethiwe, izikhwama ezintathu zesiteshi sombala zikuvumela ukuba uhlakulele ukukhanya nobumnyama bombala ngamunye ngaphakathi kwesithombe sakho. I-slider Luminosity izovame ukubonakala ingenasici noma ayikho umphumela, kodwa kwezinye izimo, ingasiza ukwenza isithombe esimnyama nesimhlophe sibonakale siyiqiniso nakakhulu esihlokweni sokuqala.
Okulandelayo, ngizokukhombisa ukuthi izilungiselelo ezihlukene kanjani ngaphakathi kwe- Channel Mixer zingakhipha imiphumela ehluke kakhulu emnyama nomhlophe kusuka esithombeni sokuqala se-digital. Ekhasini elilandelayo ngizokukhombisa indlela engikhiqize ukuguqulwa kwe-mono ngesibhakabhaka esibumnyama bese ikhasi elilandelayo lizobonisa isithombe esifanayo nesibhakabhaka esibonisiwe.

Shintsha isithombe ku-Black and White nge-Sky Sky
Isibonelo sethu sokuqala sokuguqula isithombe sedijithali kumnyama nomhlophe sizokubonisa indlela yokukhiqiza umphumela ngesibhakabhaka esibumnyama esizokwenza ukuthi umhlophe wesakhiwo uphumelele ngempela.
Chofoza okokuqala ebhokisini le- Monochrome ukuze ulikhawule futhi uzobona ukuthi isithonjana sokubuka kuqala siba mnyama nomhlophe. Sizosebenzisa isithonjana sokubuka kuqala ukuze sibone ukuthi izinguquko zethu zishintsha kanjani ukubukeka kwethu kokuguqulwa kwe-mono. Khumbula ukuthi ungachofoza izithombe ezimbili zokukhulisa ingilazi ukuze usondeza futhi uphume uma udinga ukuthola umbono ongcono wendawo yesithombe sakho.
Qaphela ukuthi uma uqala ukuchofoza ebhokisini le- Monochrome , isilayidi esiBomvu sisethelwe ku-100 kanti amanye ama-sliders amabili ombala asethelwe ku-zero. Ukuze uqinisekise ukuthi imiphumela yokuphela ibheka njengokwemvelo ngangokunokwenzeka, amanani aphelele kuwo wonke ama-sliders amathathu kufanele aphelele 100. Uma amanani agcina angaphansi kuka-100, isithombe esiwumphumela sizobonakala sibe mnyama futhi inani eliphakeme kunamaphesenti angu-100 lizokwenza livele licace.
Ngenxa yokuthi ngifuna isibhakabhaka esibumnyama, ngidonsela isilayidi seBluphu ngakwesobunxele kuya kwesilinganiso se -50%. Okubangela inani eliphelele lama-50 lisho ukuthi ukubukwa kuqala kubonakala kunomnyama kunalokho okufanele. Ukuze ngikukhokhele lokho, ngidinga ukuhambisa eyodwa noma zombili ezinye izikhwama ezimbili ngakwesokudla. Ngahlala lapho ngishukumisela i- Green slider ibe ngu-20, ekhanyisa amahlamvu emithi kancane ngaphandle kokuba nomthelela omkhulu esibhakabhakeni, futhi sishicilela i- Red slider ibe ngu-130 esinikeza inani eliphelele lama-100 kuwo wonke ama-sliders amathathu.

Shintsha isithombe ku-Black and White nge-Sky Sky
Lesi sithombe esilandelayo sikhombisa indlela yokuguqula isithombe esifanayo sedijithali kumnyama nomhlophe ngezulu elikhanyayo. Iphuzu eliphathelene nokugcina amanani alinganiselwe kuwo wonke ama-sliders amathathu ombala kuya ku-100 asebenza ngokufana nanjengaphambili.
Ngenxa yokuthi isibhakabhaka sinokukhanya okuluhlaza okwesibhakabhaka, ukukhanyisa isibhakabhaka, sidinga ukukhanyisa isiteshi esibhakabhaka. Izilungiselelo engangizisebenzisile zibonwe ukuthi i- Blue slider iqhubekele ku-150, i- Green yanda ibe ngu-30 futhi isiteshi esibomvu sinciphisa sibe ngu -80.
Uma uqhathanisa lesi sithombe nakweminye ukuguqulwa kokubili okukhonjisiwe kulesi sifundo, uzobona ukuthi le ndlela yokusebenzisa i- Channel Mixer inikeza ikhono lokukhiqiza imiphumela ehluke kakhulu uma uguqula izithombe zakho zedijithali kumnyama nomhlophe ku-GIMP.
