Ukuqonda imibala yembala ku-Photography Photography
I-RGB, i-CMYK ... itholakala njenge-sunch of soup alphabet. Eqinisweni, asetshenziselwa ukuchaza umbala ezweni le-digital photography. Kubalulekile ukuthi abathwebuli bezithombe babe nokuqonda la magama amabili ngoba banomthelela omkhulu embala wezithombe zakho, kokubili esikrinini nasekuphrintiwe.
Ukuchazwa okusheshayo yi: i-RGB yilebhu futhi i-CMYK yimiqulu. Kuyinto encane kakhulu kunalokho, ngakho-ke ake sibheke izibuko zemibala.
Iyini i-RGB?
I-RGB imele i- Red, Green, neBluetooth futhi ibhekisela emibala emithathu eyinhloko engavunyelwa ngaso sonke isikhathi ngokuhlukahluka okuhlukile ukukhiqiza imibala ehlukene.
Uma uthatha isithombe ku- DSLR yakho, ikhamera yakho izobhala ibhola lakho usebenzisa i-spectrum ye-RGB. Abaqaphi bekhompyutha nabo basebenza ku- RGB , ngakho kulula kubasebenzisi ukuthi balindele ukuthi lokho abakubona ku-screen yabo ye-LCD kuyoba yilokho abakubonayo ekuqapha kwabo.
I-RGB yaziwa njenge-color spectrum, njengoba ithembela ekungenizeni amanani ahlukene emibala emithathu ukwenza imibala ehlukene.
- Esikhathini sombukiso we-RGB, kunamazinga angu-256 okukhanya okukhiqiza amathuba ombala angu-16,777,216 (256x256x256).
- Ngokubeka umbala ngamunye we-RGB esimisweni se- "0," singenza umnyama.
- Ngokufanayo, ukulungiselelwa kwe "255" kumbala ngamunye kudala mhlophe.
Ngakho-ke, i-RGB yiyona mboni ehlelwe yi-DSLRs kanye nabaqaphi bekhompiyutha, njengoba ivumela ukuthi sibheke imibala yeqiniso kuya ekuphileni esibukweni.
Iyini i-CMYK?
Kodwa-ke, uma sifuna ukuphrinta izithombe zethu besebenzisa i-spectrum yembala efanele, sidinga ukuguqula ku-CMYK. Lokhu kusho i-Cyan, Magenta, Yellow, noMnyama.
I-CMYK iyinhlanganisela yombala wokukhipha, njengama-cyan, magenta no-pigments aphuzi asetshenziswa njengezihlungi. Lokhu kusho ukuthi basusa inani elihlukahlukene lokubomvu, eliluhlaza, neluhlaza okwesibhakabhaka kusuka ekukhanyeni okumhlophe ukukhiqiza imibala ehlukene.
Ngakho-ke, isithombe esiboniswe kumqapha wekhompiyutha angeke sifane nokuphrinta, ngaphandle uma i-spectrum ye-RGB iguqulwa ibe yi-CMYK. Nakuba amaphrinta amaningi manje eshintsha kusuka ku-RGB kuya ku-CMYK ngokuzenzekelayo, inqubo ayikakapheli. Njengoba i-RGB ingenawo umzila omnyama ozinikezele, abamnyama bangabonakala becebile kakhulu.
Ukusebenza nama-Printers
Ubuchwepheshe buguquke ngokushesha eminyakeni yamuva futhi akudingeki ngaso sonke isikhathi ukuguqulwa kusuka ku-RGB kuya ku-CMYK uma udinga ukuphrinta isithombe. Noma kunjalo, kunezinye izimo lapho lokhu kudingekile.
Ukuprinta ekhaya
Amaphrinta amaningi edeskithophu emakhaya namahhovisi asebenzisa ama-inks we-CMYK. Ubuchwepheshe bokuphrinta kokubili izinhlelo zokusebenza zesofthiwe kanye namaphrinta manje enza umsebenzi omuhle kakhulu wokuguqula imibala ye-RGB ibe yi-CMYK.
Ngokuyinhloko, iphrinta ekhaya akudingeki sikhathazeke ngokuguqulwa. Noma kunjalo, uma uthola ukuthi abamnyama bakho abalungile, ungase ufune ukwenza ukuguqulwa nokuphrinta kokuhlola ukuze ubone ukuthi lokho kusiza.
Ukusebenza nabashicileli bezebhizinisi
Kunezinhlobo ezimbili zamaphrinta ezentengiselwano ongasebenza ngazo futhi abanye bangakucela ukuba uguqule isithombe ku-CMYK.
Ezimweni eziningi namuhla, ngeke kudingeke wenze ukuguqulwa. Lokhu kuyiqiniso ngokukhethekile uma usebenzisa i-lab yokunyathelisa isithombe. Isofthiwe yabo kanye nezochwepheshe bazovame ukusingatha izinselele eziningi zombala ukukhiqiza ama-movie angcono kakhulu okuthwebula izithombe. Bafuna ukwenza ikhasimende lijabule futhi bazi ukuthi wonke umuntu akanakho ukuqonda okugcwele ubuchwepheshe.
Uma uthatha umsebenzi wakho kumprinta wehluzo ozinikezele ngezinto ezifana namakhadikhadi, izincwajana, njll, bangase bacele isithombe ku-CMYK. Lokhu kungenxa yokuthi ifomethi abaye basebenze ngaso sonke isikhathi. I-CMYK, eyaziwa nangokunyatheliswa kombala omine, ibuyele ezinsukwini zokunyathelisa umbala nokucubungula ngaphambi kokuba ubuchwepheshe be-digital bucatshangwe.
Iguqula kusuka ku-RGB kuya ku-CMYK
Uma udinga ukuguqula isithombe kusuka ku-CMYK kuya ku-RGB yephrinta, kulula kakhulu futhi cishe yonke isofthiwe yokuhlela isithombe inokukhetha.
Ku-Photoshop, kulula njengokuya ku: Isithombe> Imodi> Umbala we-CMYK.
Uma usithumele ifayela kuphrinta yakho, sebenza nabo futhi wenze ukuphrinta kokuhlola (ubufakazi) ukuqinisekisa ukuthi umbala yilokho okulindele. Futhi, bafuna ikhasimende lijabule futhi lizokujabulela ukukuhamba ngenqubo.
