Imvamisa ngesikhathi sokudutshulwa kwesithombe, umthwebuli zithombe angathola izithombe eziveziwe noma zibe mnyama kakhulu.
Kulesi sifundo uzothola ulwazi ngezindlela zokukhanya noma ukufiphala kwendawo kwezithombe.
Umbuzo onengqondo ungavela: kungani lokhu kudingekile uma uhlelo luqukethe amathuluzi anjenge I-Dodge (Clarifier) futhi Shisa (Dimmer)?
Konke ukushaya ukuthi amathuluzi akhona ohlelweni kungenzeka angasebenzi kahle, ngakho-ke emsebenzini lapho kudingeka kakhulu ikhwalithi ephezulu, ukusetshenziswa kwawo kukhawulelwe, lokhu kungabonakala ngekhwalithi esabekayo yezithombe ezibuye zatholakala.
Kuyelulekwa ukusebenzisa ezinye izindlela zokulawula i-chiaroscuro, sizokwazi enye yezindlela ezikhona.
1. Vula isithombe. Izithandani ezimbalwa ezisanda kushada esithombeni somshado kufanele zibukeke kahle kakhulu futhi zidonse ukunakwa.
Hlola isithombe ngokucophelela. Ebusweni bale mbhangqwana osemusha, izithunzi ezibukhali nesizinda esikhanyayo esiseduze siyabonakala. Lo mphumela utholakala lapho ukudubula ngaphansi kokukhanya okukhanyayo, bezithombe abanolwazi kakhulu basebenzisa i-flash, ekuvumela ukuthi uthambise imigqa. Ngokwezimo ezithile, sizokwenza lokhu ukuzikhohlisa.
Ake siqale, okubaluleke kakhulu kuqala ukwengeza enye ungqimba wesithombe. Inkinobho yokuqinisa ALT, chofoza isithonjana sidala esinye isendlalelo, esisendaweni engezansi kwephalethi.
Ewindini elivulayo, faka igama lesendlalelo. Khumbula ukukhetha okukhethwa kukho. Imbondela.
Kungenzeka ukusebenzisa inketho Ukukhanya Kokuthambile, lokhu kuyadingeka uma uphinda ubuke imidwebo lapho kusondele khona.
Beka uphawu "Gcwalisa" izinketho zombala ongathathi hlangothi Qoqana.
Kuvela 50% grey.
Konke kulungiselelwe izinyathelo ezilandelayo.
2. Setha kabusha yonke imibala lapho uthinta inkinobho D. Khetha uBhulashi (Ibhulashi). I-Opacity ayisethiwe 10%.
Khetha umbala omhlophe, imodi yokukhanyisa ivuliwe.
Lapho usebenza ngokufiphaza noma ukukhanyisa, kufanele wenze izenzo ngokulandelana. Sithambisa izithunzi ezikhona zabasanda kushada.
Uma weqa, kufanele ukhethe 50% grey, ungachofoza umbala ongaphambili, otholakala kubha yamathuluzi. Faka inani ewindini 128 ngemibala eluhlaza okwesibhakabhaka, ebomvu nokuluhlaza.
3. Yenza mnyama ingemuva. Sisetha umbala ube mnyama, futhi sisebenza ngemodi yokufiphala. Setha opacity low. Kulesi sinketho, kunconywa ukukhetha ibhulashi enkulu.
Isendlalelo okwenzeka ngaso maniplication sibukeka sifana nalezi:
4. Nawu umphumela.
Izinzuzo zendlela zilele ekuphathweni nasekuphatheni kwenqubo. Uma ukunciphisa kancane komphumela kuyadingeka, kungenzeka ukufaka ukufiphala okuncane noma ukuguqula isilinganiso se-opacity.
Kukhona amathuba okususa okuphelele kwezinguquko ezingxenyeni ezidingekayo, ugcwalise izindawo ezidingeka ngamaphesenti angama-50 grey.
