Ungawutshintsha njani ngokufanelekileyo umbala kwi-GIMP

Xa sasixoxa ngamathuba e GIMP, kumxholo GIMP ... apho ewe nalapho ngamanye amaxesha, njengesixhobo esiluncedo kubugcisa begraphic, into esivumelana ngayo sonke kukuba ukwenza uhlengahlengiso lombala kwimowudi RGB kuhle kakhulu. Ngoko ke, ndiya kuzama ukuphuhlisa esi sihloko ngaphandle kwenjongo enye ngaphandle kokudala isikhokelo esinokuba luncedo kwabo batsha kule mizobo yembala yedijithali.

I.-Kutheni kufuneka silungise umbala?

Ewe, okokuqala kufuneka siqonde ukuba yintoni umbala kwaye, okona kubaluleke kakhulu, ukuba siwubona njani, ukwazi ukuba kutheni uthotho lwembuyekezo kufuneka lwenzelwe isixhobo -Imonitha yePC okanye umshicileli wedijithali- imele ngokusondeleyo kwinyani kangangoko kunokwenzeka.

Yintoni umbala? Umbala luphawu esilubona kwizinto xa kukho ukukhanya. Ukukhanya kuyilwe ngamaza ombane asasazeka malunga neekhilomitha ezingama-300.000 XNUMX ngomzuzwana. Oku kuthetha ukuba amehlo ethu asabela kwisiganeko samandla kwaye kungekhona kumcimbi ngokwawo.

Ithetha ntoni le nto? Ngamazwi alula:

  1. Imibala ayizizo iipropati zangaphakathi zezinto kodwa yokukhanya.
  2. Ngaphandle kokukhanya -ubumnyama obupheleleyo– akukho ukubona umbala
  3. Sibona imibala kuba izinto zinepropathi yokufunxa indawo yokukhanya kunye nokubonakalisa enye indawo.

Ngoku, kufuneka kucaciswe ukuba umntu unokubona kuphela inxenye yala maza okukhanya ombane, siyibiza le ndawo ibonakalayo. "I-Spectrum ebonakalayo" yaye ngabo aba ubude bamaza buphakathi kwama-380 nama-770 eenanometer.

Kutheni i-RGB?  Ixesha elide umntu ukhangele indlela yokubamba kunye nokuvelisa umbala, ezama ukusondela ngokusemandleni kwindlela ayibona ngayo kwindalo, zombini iindlela. "omakhanikhi" okanye eyenziweyo ukwenza njalo ziifowuni Ukongeza y Ukuthabatha. Ilizwi RGB kuvela Ubomvu, uGren y Luhlaza -Buhlaza obuBomvu, kwaye luhlazal- kwaye ihambelana nendlela Ukongeza ukuvelisa umbala.

Inkqubo eyongezelelweyo yoMbala

Uveliswa njani umfanekiso kwakhona kwinkqubo yeRGB

Okwangoku asiyi kuhlalutya, ngenxa yezizathu zexesha kunye nokuphepha ukudala ukudideka, inkqubo Ukuthabatha kwaye siya kugxininisa ngokukodwa RGB (Ezongeziweyo), yile siza kuyisebenzisa kuyo I-GIMP, kuba le yinkqubo esetyenziselwa ukuvelisa umbala kwiimonitha zethu kwaye yindlela iikhamera eziwubamba ngayo.

"Kakuhle kakhulu tina... yonke loo choro ilungile kakhulu, kodwa kutheni kufuneka uhlengahlengise umbala?", abafundi bam ababini baya kuthi.

Ndiza kuzama ukuyichaza ngendlela eqondakalayo kumntu wonke: xa sisiya kwivenkile yezixhobo zasekhaya kuyinto eqhelekileyo ukuba sibone iiseti ezininzi zeTV kwaye, nangona ziguqulelwe kwisitishi esifanayo, imibala ibonakala. ezahlukeneyo. Oku kungenxa yesenzeko somzimba esibizwa ngokuba Uluhlu lweMbala eDynamic engeyonto ngaphandle kokukwazi kwesixhobo ngasinye ukumela indawo yombala obonakalayo.

Ke, umzekelo, iikhamera ezimbini zinokubamba uluhlu lwemibala eyahlukeneyo nokuba sisiphi na isisombululo kwiipikseli nge-intshi nganye.
