Indlela yokulungisa umbala we-Cast Cast kwi-Balance White Balance kwi-Photos kunye ne-GIMP

Iikhamera zedijithali zichanekile kwaye zinokusetyelwa ukuba zikhethe ngokuzenzekelayo izicwangciso ezifanelekileyo kwiimeko ezininzi ukuqinisekisa ukuba iifoto ozithathayo ziphezulu njengomgangatho ophezulu. Nangona kunjalo, kwezinye iimeko bangenokuba neengxaki ekukhetheni ukulungelelaniswa kokulungelelaniswa kwemhlophe.

I-GIMP-mfutshane kwi-GNU Image Manipulation Programme-isofthiwe evulekileyo yokuhlela umfanekiso owenza ukuba kube lula ukulungisa ibhalansi emhlophe.

Ukulinganiswa koMgca oMhlophe kuchaphazela njani iifoto

Ukukhanya kakhulu kubonakala kumhlophe kwiso lomntu, kodwa ngokwenene, iintlobo ezahlukeneyo zokukhanya, ezifana nokukhanya kwelanga kunye nokukhanya kwe-tungsten, zinemibala eyahlukileyo, kwaye iikhamera zedijithali ziyaziqonda.

Ukuba ikhamera inomgca wayo omhlophe isetyenziswe ngokungalunganga ukuba uhlobo lokukhanya luyifake, ifoto ifuthe iya kuba nombala ongaqhelekanga. Uyabona ukuba kwiphantshi ephuzi elifudumele kwicala lasekhohlo elingasentla. Isithunzi ngakwesokudla emva kokulungiswa okuchazwe ngezantsi.

Ngaba kufuneka usebenzise i-RAW Ifomathi yeefoto?

Abafakeli beefoto abalukhuni baya kuvakalisa ukuba kufuneka uhlale udubula kwifom ye-RAW kuba unako ukutshintsha ngokulula umgca omhlophe wesithombe ngexesha lokucubungula. Ukuba ufuna iifoto ezingcono kakhulu, i- RAW iyindlela yokuhamba.

Nangona kunjalo, ukuba ungumfoto-mfanekiso ongathandabuzekiyo, amanyathelo alongezelelweyo ekuqwalaseleni ifomathi ye-RAW ingaba nzima nakakhulu kunye nokuchitha ixesha. Xa udubula imifanekiso ye-JPG , ikhamera yakho ilandelelanisa ezininzi zezi zicwangciso zokucubungela, njengokunciphisa nokunciphisa ingxolo.

Ukulungisa umbala we-Cast nge-Pick Grey Tool

Ukuba ufumene isithunzi kunye nombala ojiweyo, ngoko uya kuba uphelele kule tutorial.

1. Vula isithombe kwi-GIMP.
2. Yiya kuMbala > Iinqanaba zokuvula incoko yenqanaba.
3. Cofa iqhosha le- Pick , elibukeka njengepipette elinomthi obomvu.
4. Cofa kwisithombe usebenzisa i-gray picker ukuze uchaze ukuba yintoni ithoni ephakathi kwegrey. Isixhobo seNqanaba siya kwenza ukulungiswa okuzenzekelayo kwisithombe esisekelwe kulokhu ukuphucula umbala kunye nokuvezwa kwesithombe.
   
   Ukuba isiphumo asibukeka kakuhle, cofa iqhosha lokuHlaziya uze uzame indawo eyahlukileyo yomfanekiso.
5. Xa imibala ibonakala yendalo, cofa iqhosha le- OK .

Nangona le nkqubo ingakhokelela kwimbala engaphezulu yemvelo, kunokwenzeka ukuba ukuvezwa kungabangela ubuncinane, ngoko ulungele ukwenza izilungiso ezongezelelweyo, ezifana nokusebenzisa ii-curves kwi-GIMP .

Kulo mfanekiso ngakwesobunxele, uza kubona utshintsho olukhulu. Kukho umbala omncinci owenziwe kwisithombe, nangona kunjalo. Singazenza izilungiso ezincinci ukunciphisa oku kuthunyelwa ngokusebenzisa izicwangciso ezilandelayo.

Lungisa ibhalansi yemibala

Kukho ncinane encinci ye-tinge ebomvu ukuya kwimifanekiso kwisithombe esedlule, kwaye oku kungatshintshwa usebenzisa i-Color Balance kunye ne-Hue-Saturation tools.

1. Yiya kuMbala > Umbala Wemibala ukuvula incoko yababini bhokisi. Uza kubona amaqhosha amathathu oonomathotho phantsi kweCandelo loKhetho ukulungiswa kwesihloko; ezi zivumela ukuba ujolise iintlobo ezahlukeneyo zeetoni kwisithombe. Ngokuxhomekeka kwisithombe sakho, usenokungafuneki ukwenza utshintsho kwiShadows, Midtones, kunye neePhambili.
2. Cofa kwiqhosha le- Shadows iqhosha.
3. Hambisa i- Magenta-Green slider encinci kunene. Oku kunciphisa umthamo we-magenta kwimimandla yezithunzi zesithombe, ngaloo ndlela ukunciphisa i-tinge ebomvu. Nangona kunjalo, qaphela ukuba inani lokuluhlaza linyuka, ngoko jonga ukuba utshintsho lwakho aluyi kutshintsha omnye umbala owenziwe ngomnye.
4. Kwi-Midtones kunye neengqamaniso, guqula umgca we-Cyan-Red. Iimpawu ezisetyenziswe kulo mzekelo wesithombe zi:

• Izithunzi: I-Magenta-Green 10
• I-Midtones: I-Cyan-Red -5, iMagenta-Green 5
• Amaphukula ephambili: I-Cyan-Red -6, Magenta-Green 6

Ukulungiswa komgca wemibala kuye kwenza ukuphuculwa komncinci kumfanekiso. Emva koko, siya kulungelelanisa i-Hue-Saturation yokulungiswa kombala.

Lungisa i-Hue-Saturation

Isithombeni sisenombala omncinci obomvu, ngoko siza kusebenzisa i-Hue-Saturation ukwenza ukulungiswa okuncinci. Le ndlela ifanele isetyenziswe ngononophelo njengoko inokuthi iqhubekisele phambili eminye imibala ebomvu kwisithombe, kwaye ingenakusebenza kakuhle kwiimeko zonke.

1. Yiya kuMbala > I- Hue-Saturation ukuze uvule incoko ye-Hue-Saturation dialog. Iilawuli apha zingasetyenziswa ukuphazamisa yonke imibala kwisithombe ngokulinganayo, kodwa kule ngxaki sifuna ukulungelelanisa imibala ebomvu neyemigenta.
2. Cofa kwiqhosha lerediyo elimatshintshi M kwaye ulayishe isilayidi sokucwangcisa ngakwesobunxele ukuze unciphise inani le-magenta kwisithombe.
3. Cofa iqhosha lerediyo elimatshintshiweyo R ukuze utshintshe ubungqongqo obomvu kwisithombe.

Kulo mfa nekiso, i-magenta saturation isetyenziswe kwi -19, kwaye i-saturation ebomvu iya -29. Kufuneka ukwazi ukubona emfanekisweni indlela umbala obomvu obuncitshisiweyo oye wanciphisa ngayo.

Ifoto ayilungelekanga, kodwa ezi zinto zingakunceda ufumane isithombe esilungileyo.
