Ukuqonda imibala yemifanekiso kwi-Digital Photography
I-RGB, i-CMYK ... ivakala ngathi isobho se-alfabhethi. Enyanisweni, zisetyenziselwa ukuchaza umbala kwilizwe lezithombe zedijithali. Kubalulekile ukuba abathwebuli beefoto babe nokuqonda kwezi mibini zibini ngenxa yokuba banefuthe elikhulu kumbala weefoto zenu, zombini kwesikrini kunye nokuprinta.
Ingcaciso ekhawulezayo yile: I-RGB yewebhu kwaye i-CMYK yimiqulu. Kuyinto encinci kunzima kunoko, ngoko masiqwalasele ngokukhawuleza imibala yembala.
Yintoni iRGB?
I-RGB imele i- Red, Green, neBlue kwaye ibhekisela kwimibandela emithathu eyona nto ihlala idibaniswa ndawonye kwiintlobo ezahlukeneyo ukuvelisa imibala eyahlukileyo.
Xa uthatha isithombe kwi- DSLR yakho, ikhamera yakho iya kubhala ibhola lakho usebenzisa i-RGB. Abagadi beekhompyutha basebenza kwi- RGB , ngoko kulula ukuba abasebenzisi balindele ukuba oko bakubonayo kwi-screen yabo ye-LCD baya kuba yiloo nto abayibonayo kwisohlo yabo.
I-RGB yaziwa ngokuba ngumbala wongeziweyo, njengokuba ithembela ekuncediseni inani elithile lemibala emithathu ukwenza imibala eyahlukileyo.
- Kwimbonakalo ye-RGB, kukho amaqondo angama-256 okukhanya okuvelisa amathuba angama-16,777,216 (256x256x256).
- Ngokuseta umbala ngamnye weRGB kwisimo "0," sinokuvelisa abamnyama.
- Ngokufanayo, isilungiselelo "255" kumbala ngamnye udala umhlophe.
Ngako oko, i-RGB yinkampani engagqibekanga kwi-DSLRs kunye nabahloli bekhompyutha, njengoko ivumela ukuba sibuke imibala okwenyaniso kwi-on screen.
Yintoni i-CMYK?
Nangona kunjalo, ukuba sifuna ukushicilela imifanekiso yethu isebenzisa umbala webala ochanekileyo, kufuneka siguqule kwi-CMYK. Oku kumela iMicrosoft, Magenta, Ephuzi, noMnyama.
I-CMYK i-colortraction color, njengama-cyan, magenta kunye ne-yellow pigments asetyenziswa njengezihlunu. Oku kuthetha ukuba bakhupha iimali ezahlukahlukeneyo ezibomvu, eziluhlaza kunye nohlaza okwesibhakabhaka ekukhanyeni okumhlophe ukuvelisa imibala eyahlukileyo.
Ngako oko, umfanekiso oboniswe kumboniso wekhompyutheni awukwazi ukufana nokushicilelwa, ngaphandle kokuba i-RGB ibonakala iguqulelwe kwi-CMYK. Nangona abaninzi abaphrinta ngoku beguqula ukusuka kwi-RGB ukuya kwi-CMYk ngokuzenzekelayo, le nkqubo ayifanelekanga. Njengoko i-RGB ingenawo umzila omnyama ozinikezele, abamnyama bangabonakala bezityebi kakhulu.
Ukusebenza nabaPrinta
I-teknoloji iguqukile ngokukhawuleza kwiminyaka yamuva kwaye akusoloko imfuneko ukwenza ukuguqulwa ukusuka kwi-RGB ukuya kwi-CMYK xa ufuna ukuprinta ifoto. Nangona kunjalo, kukho ezinye iimeko apho oku kuyimfuneko.
Ukuprinta ekhaya
Iiprinta ezininzi zekhompyutha kumakhaya nakwiiofisi zisebenzisa ii-inks ze-CMYK. Ubuchwephesha bokushicilela kuzo zombini izicelo zokusebenza kunye nabaphrinta ngoku benza umsebenzi omhle kakhulu wokuguqula imibala ye-RGB ibe yi-CMYK.
Ngokona nxalenye, umshicileli wekhaya akudingeki akhathazeke ngokuguqulwa. Nangona kunjalo, ukuba ufumanisa ukuba abamnyama bakho abakulungile, unokufuna ukwenza ukuguqulwa nokuprintwa kovavanyo ukuze ubone ukuba oko kunceda.
Ukusebenza nabashicileli bezorhwebo
Kukho iintlobo ezimbini zokushicilela zentengiso onokusebenzisana nazo kwaye abanye banokucela ukuba uguqulwe isithombe kwi-CMYK.
Kwiimeko ezininzi namhlanje, awuyi kuyenza ukuguqulwa. Oku kuyinyaniso xa usebenzisa ibhodi yokushicilela isithombe. Isoftware kunye neengcali zabo ziza kubamba imingeni emininzi yembala ukuvelisa iiflethi ezibonakalayo ezifanelekileyo. Bafuna ukwenza umthengi onwabe kwaye bayazi ukuba wonke umntu akanakho ukuqonda ngokupheleleyo iteknoloji.
Ukuba uthatha umsebenzi wakho kumshicileli wezithombe ezizinikezele ngezinto ezifana neepastadi, iincwadana, njl., Banokucela umfanekiso kwi-CMYK. Oku kungenxa yokuba ifomathi abaye basebenza nabo. I-CMYK, eyaziwa nangokushicilelwa kwemibala emine, ibuyele kwiintsuku zokushicilela umbala kunye nokucwangciswa ngaphambi kokuba ubugcisa bedijithali bucingelwe.
Ukuguqula ukusuka kwi-RGB ukuya kwi-CMYK
Ukuba ufuna ukuguqula umfanekiso ukusuka kwi-CMYK ukuya ku-RGB yoshicilelo, kulula kakhulu kwaye phantse yonke i-software yokwenza isofthiwe ikhetha le ndlela.
Kwi-Photoshop, kulula njengoko uhamba ngayo: Umfanekiso> Imodi> Umbala we-CMYK.
Emva kokuba uthumele ifayile kumshicileli wakho, sebenzisana nabo kwaye wenze uvavanyo lokuhlola (ubungqina) ukuqinisekisa ukuba umbala ulindele. Kwakhona, bafuna ukuba umthengi abe nolonwabo kwaye uya kuvuyela ukuhamba nawe kwinkqubo.
