Indlela Yokulungisa Umbala We-Cast kusuka ekungalinganisweni Okumhlophe Kwezithombe ku-GIMP

Amakhamera adijithali ahlukahlukeneyo futhi angasethwa ngokuzenzakalelayo ukukhetha izilungiselelo ezingcono kakhulu zezimo eziningi ukuqinisekisa ukuthi izithombe ozithathayo zifana nekhwalithi eliphezulu ngangokunokwenzeka. Kodwa-ke, kwezinye izimo bangase babe nezinkinga ekukhethweni kwesilungiselelo sokulinganisela esimhlophe esimhlophe.

I-GIMP-emfushane ye-GNU Image Manipulation Programme - isofthiwe evulekile yokuhlela isithombe esenza kube lula ukulungisa ibhalansi emhlophe.

Ukulinganisela Kwemhlophe Kuthinta Izithombe

Ukukhanya okuningi kubonakala kumhlophe ngeso lomuntu, kodwa empeleni, izinhlobo ezihlukahlukene zokukhanya, ezifana nokukhanya kwelanga nokukhanya kwe-tungsten, zinemibala ehlukile, futhi amakhamera adijithali azwela lokhu.

Uma ikhamera ibhalansi yayo emhlophe isethelwe ngokungalungile ngohlobo lokukhanya elibamba, isithombe esilandelayo sizoba nombala ongavamile. Ungabona ukuthi endaweni ephuzi ephuzi kwesithombe sokunxele ngakwesokunxele. Isithombe ngakwesokudla silandela ukulungiswa okuchazwe ngezansi.

Ingabe Kufanele Usebenzise Amafomethi We-RAW?

Abathwebuli bezithombe ezinzulu bazomemezela ukuthi kufanele udubule njalo kwifomethi ye-RAW ngoba uyakwazi ukushintsha kalula ibhalansi emhlophe yesithombe ngesikhathi sokucubungula. Uma ufuna izithombe ezinhle kakhulu, khona-ke i- RAW iyindlela yokuhamba.

Kodwa-ke, uma ungumthwebuli wezithombe ezingathí sina, izinyathelo ezengeziwe ekusetshenzisweni kwefomethi ye-RAW zingaba nzima nakakhulu futhi zidla isikhathi. Uma udubula izithombe ze-JPG , ikhamera yakho isebenza ngokuzenzakalelayo eziningi zalezi zinyathelo zokucubungula, njengokunciphisa nokunciphisa umsindo.

Lungisa i-Cast Cast ne-Pick Grey Tool

Uma unesithombe esine-color cast, khona-ke kuyobe iphelele kulolu hlelo.

1. Vula isithombe ku-GIMP.
2. Iya kumbala > Amazinga ukuvula ingxoxo yezinga.
3. Chofoza inkinobho ye- Pick , ebonakala njenge-pipette ene-gray stem.
4. Chofoza esithombeni usebenzisa i-picker yephuzu elimhlophe ukuze uchaze ukuthi iyiphi ithoni ephakathi kwegrey. Ithuluzi leZinga lizokwenza ukulungiswa okuzenzakalelayo esithombeni okusekelwe kulokhu ukuthuthukisa umbala nokuvezwa kwesithombe.
   
   Uma umphumela ungabukeka kahle, chofoza inkinobho yokusetha kabusha bese uzama indawo ehlukile yesithombe.
5. Lapho imibala ibheka imvelo, chofoza inkinobho OK .

Ngenkathi le nqubo ingabangela imibala yemvelo engaphezulu, kungenzeka ukuthi ukuvezwa kungase kuhlupheke kancane, ngakho-ke ulungele ukwenza izilungiso ezengeziwe, njengokusebenzisa i- curves ku-GIMP .

Esithombeni ngakwesobunxele, uzobona ushintsho olukhulu. Kukhona umbala omncane owenzelwe isithombe, noma kunjalo. Singenza izilungiso ezincane ukunciphisa lokhu kuthunyelwa ngokusebenzisa amasu alandelayo.

Lungisa ukulinganisa kombala

Kusasele kancane kancane kwe-tinge ebomvu kuya emibala esithombeni sangaphambilini, futhi lokhu kungashintshwa kusetshenziswa i-Color Balance namathuluzi we-Hue-Saturation.

1. Iya kumbala > Umbala Wokubala ukuvula ingxoxo ye-Color balance. Uzobona izinkinobho ezintathu zomsakazo ngaphansi kohlelo lokukhetha ukulungisa ukuqondisa; lawa akuvumela ukuthi ubheke amathafa we-tonal ahlukene esithombeni. Kuye ngesithombe sakho, kungase kungadingeki wenze izinguquko ku-Shadows, Midtones, nakuPhezukonke.
2. Chofoza inkinobho yomsakazo we- Shadows .
3. Hambisa isilayidi se- Magenta-Green kancane ngakwesokudla. Lokhu kunciphisa inani le-magenta ezindaweni zethunzi zesithombe, ngaleyo ndlela kunciphisa i-tinge ebomvu. Kodwa-ke, qaphela ukuthi inani lohlaza liyanda, ngakho-ke qaphela ukuthi ukulungiswa kwakho akufaki esikhundleni sombala owodwa owenziwe ngomunye.
4. KuMidtones nasePhakamisekeni, hlela isilayidi se-Cyan-Red. Amagugu asetshenziswe kulesi sibonelo sithombe yi:

• Izithunzi: Magenta-Green 10
• Midtones: I-Cyan-Red -5, iMagenta-Green 5
• Amaphuzu avelele: I-Cyan-Red -6, Magenta-Green 6

Ukulungisa ibhalansi yembala kuye kwenze ngcono ukuthuthukiswa kwesithombe. Okulandelayo, sizobe sishintsha i-Hue-Saturation ukuze kulungiswe ukulungiswa kombala.

Lungisa i-Hue-Saturation

Isithombe sinebala elincane obomvu, ngakho-ke sizosebenzisa i-Hue-Saturation ukwenza ukulungisa okuncane. Le nqubo kufanele isetshenziswe ngokucophelela ngoba ingakwazi ukugxilisa amanye ama-anomalies ombala esithombeni, futhi ingase ingasebenzi kahle kuzo zonke izimo.

1. Hamba ku- Colors > Hue-Saturation ukuvula ingxoxo ye-Hue-Saturation. Izilawuli lapha zingasetshenziswa ukuphazamisa yonke imibala esithombeni ngokulinganayo, kodwa kulokhu sifuna ukulungisa imibala ebomvu nelomagenta kuphela.
2. Chofoza inkinobho yomsakazo umakwe M bese uslayida isilayidi sokusondeza ngakwesobunxele ukuze unciphise inani le-magenta esithombeni.
3. Chofoza inkinobho yomsakazo emakwe R ukushintsha ubukhulu obomvu esithombeni.

Kulesi sithombe, ukufakwa kwe-magenta kusethelwe ku -19, futhi ukufaka saturation obomvu kuya -29. Kufanele ukwazi ukubona esithombeni ukuthi umbala omncane obomvu uphonswe kanjani.

Isithombe asiphelelanga, kepha lezi zindlela zingakusiza ukuba ubeke isithombe esihle semfanelo.
