Funda ukuthi ungayisebenzisa nini ifomethi yohlobo lwefayili yocingo
I-JPEG, i-TIFF, ne-RAW yizakhiwo zefayili yezithombe ezicishe zonke izingcingo ze-DSLR zingasebenzisa. Ukuqala kwamakhamera kuvame ukunikeza amafomethi wefayela le-JPEG kuphela. Amanye amakhamera we-DSLR futhi adubula ku-JPEG naku-RAW ngesikhathi esisodwa. Futhi ngenkathi ungatholi eziningi zamakhamera ezinikezela nge-TIFF izithombe, amanye amakhamera athuthukile anika le fomethi yesithombe esiqondile. Qhubeka ukufunda ukuze ufunde kabanzi mayelana nohlobo ngalunye lwefomethi yefayela lesithombe.
I-JPEG
I-JPEG isebenzisa ifomethi yokucindezela ukususa amanye amaphikseli ukuthi i-algorithm yokucindezela ibona ingabalulekile, ngaleyo ndlela igcina isikhala esithile sokugcina. Ukucindezela kuzokwenzeka ezindaweni zesithombe lapho imibala yamaphikseli ephinda, njengokufana nesithombe esibonisa isibhakabhaka esiningi. I-firmware noma isofthiwe ngaphakathi kwekhamera izobala izinga lokucindezela ngesikhathi ikhamera isindisa isithombe, ngakho isikhala esilondoloziwe sikhala senzeka ngokushesha, sikhala isikhala kwimemori khadi.
Abaningi bezithombe bazosebenza ku-JPEG iningi lesikhathi, njengoba i-JPEG ifomethi yesithombe ejwayelekile kumakhamera wedijithali, iphuzu ikakhulukazi elingabizi futhi ukudubula amakhamera. Amakhamera we-Smartphone nawo aqopha kufomethi ye-JPEG iningi lesikhathi. Ikhamera ezithuthukisiwe, ezifana namakhamera we-DSLR, nazo zidubula ku-JPEG isikhathi esiningi. Uma uhlela ukwabelana ngezithombe kumanethiwekhi omphakathi, ukusebenzisa i-JPEG kuhlakaniphile, njengoba kulula ukuthumela amafayela amancane ngokusebenzisa imidiya yomphakathi.
RAW
I-RAW iseduze nekhwalithi yefilimu, idinga isikhala esiningi sokugcina. Ikhamera ye-digital ayicindezeli noma inqubo yefayela RAW nganoma iyiphi indlela. Abanye abantu babhekisela kwifomethi ye-RAW njenge "negative digital" ngoba ayishintshi lutho mayelana nefayela lapho igcina. Kuye kumakhi wekhamera yakho, ifomethi ye-RAW ingabizwa ngokuthi enye into, njenge-NEF noma i-DNG. Zonke lezi zakhiwo zifana kakhulu, yize zisebenzisa amafomethi wezithombe ezahlukene.
Ambalwa amakhamera wezinga lokuqala avumela isitoreji sefomethi yefomethi ye-RAW. Abanye abathwebuli bezithombe abaqeqeshiwe nabaphambili njengo-RAW ngoba bangakwazi ukuhlela ngokwabo isithombe sedijithali ngaphandle kokuba bakhathazeke ngokuthi yiziphi izakhi zesithombe uhlelo lokucindezela oluzosusa, njenge-JPEG. Isibonelo, ungashintsha ibhalansi emhlophe yokudubula kwesithombe ku-RAW usebenzisa isofthiwe yokuhlela isithombe. Amanye amakhamera we-smartphone aqala ukunikeza amafomethi we-RAW kanye ne-JPEG.
Okungalungile ukudubula ku-RAW kungumthamo omkhulu wesitoreji esidingekayo, okuzogcwalisa imemori khadi yakho ngokushesha. Enye inkinga ongayithola ne-RAW yukuthi awukwazi ukuyivula ngezinhlobo ezithile zokuhlela isithombe noma ukubuka isofthiwe. Isibonelo, i-Microsoft Paint ayikwazi ukuvula amafayela we-RAW. Iningi lime izinhlelo zokuhlela izithombe zodwa zingavula amafayela we-RAW.
I-TIFF
I-TIFF iyifomethi yokucindezela engalahlekelwa yimuphi ulwazi mayelana nedatha yesithombe, noma. Amafayela we-TIFF angaphezulu kakhulu ngobukhulu besedatha kunamafayela we-JPEG noma ama-RAW. I-TIFF ifomethi evamile kakhulu ekushicileleni kwehluzo noma ukucabangela kwezokwelapha kunezithombe zedijithali, nakuba kunezimo lapho abathwebuli bezobuchwepheshe bangase babe khona iphrojekthi lapho kudingeka khona ifomethi yefayela le-TIFF. Amakhamera ambalwa kakhulu anekhono lokurekhoda ku-TIFF.
Indlela yokusebenzisa i-JPEG, RAW, ne-TIFF
Ngaphandle kokuthi ungumthwebuli wezithombe ozokwenza ama-prints amakhulu, ukulungiselelwa kwe-JPEG eliphezulu kuzokuhlangabezana nezidingo zakho zedatha yesithombe. I-TIFF ne-RAW inqwabelene nabathwebuli bezithombe abaningi, ngaphandle uma unesizathu esithile sokudubula ku-TIFF noma i-RAW, njengesidingo sokuhlela isithombe esiqondile .
