Funda ixesha lokusebenzisa nganye ifayile ifayile yefayile ifayile
I-JPEG, i-TIFF, kunye ne-RAW zifomathi zefayile zeefoto eziphantse zonke iikhamera ze-DSLR zingasebenzisa. Iikhamera zokuqala zivelisa kuphela iifayile zefayile zeJPEG. Ezinye iikhamera ze-DSLR kwaye zidubule kwi-JPEG kunye ne-RAW kanyekanye. Kwaye ngelixa ungafumani ezininzi iikhamera ezinika iifoto ze-TIFF, ezinye iikhamera eziphambili zinikeza le fomathi yesimo esicacileyo. Qhubeka ufunda ukuze ufunde kabanzi malunga nohlobo ngalunye lwefayile yefayile yesithombe.
JPEG
I-JPEG isebenzisa ifomati yokunciphisa ukususa ezinye iipikseli zokuba i-algorithm yoxinzelelo ibona ingabalulekanga, ngaloo ndlela igcina indawo ethile yokugcina. Uxinzelelo luya kwenzeka kwiindawo zesithombe apho imibala yeepikseli iphinda, njengefoto ebonisa isibhakabhaka esininzi. I-firmware okanye isofthiwe ngaphakathi kwekhamera iya kuqulunqa izinga lokuxinwa ngexesha ikhamera ilondoloza umfanekiso, ngoko indawo yokugcina ifumanekile iyenzeka ngokukhawuleza, ukugcina indawo kwimemori khadi.
Uninzi lwabafaki beefoto luza kusebenza kwiJPEG ubuninzi bexesha, njengoko i-JPEG ifomati yesimo esifanayo kwiikhamera zedijithali, ngokukodwa indawo engabizi kwaye uphendule ikhamera. Iikhamera ze-smartphone nazo zirekhoda kwifom ye JPEG ubuninzi bexesha. Iikhamera eziphambili, ezifana neekhamera ze-DSLR, nazo zidubula kwiJPEG ixesha elininzi. Ukuba uceba ukwabelana ngezithombe kumajelo aseburhulumenteni, ukusebenzisa i-JPEG kuhlakaniphile, kuba kulula ukuthumela iifayile ezincinci ngeendaba zoluntu.
RAW
I-RAW isondele kumgangatho wefilimu, efuna indawo enkulu yokugcina. Ikhamera yedijithali ayicinezeli okanye iqhube ifayile ye-RAW nganoma yiphi indlela. Abanye abantu babhekisela kwifomathi ye-RAW njenge "negative digital" kuba ayitshintshi nantoni na ngefayili xa uyigcina. Ngokuxhomekeka kumenzi wakho wekhamera, ifomathi ye-RAW ingabizwa into enye, njenge-NEF okanye i-DNG. Zonke ezi zifomati zifana kakhulu, nangona zisebenzisa izakhiwo ezahlukeneyo.
Amakhamera ambalwa aqalayo avumela ukugcinwa kwefayile yefayile ye-RAW. Abanye abachwephesha abanezakhono kunye nabaphambili abafana ne-RAW kuba banokwenza ukuhlela kwabo kwiifoto zedijithali ngaphandle kokuba bakhathazeke malunga nezinto ezithathwe kwisithombe inkqubo yoxinzelelo iya kususa, njengeJPEG. Umzekelo, unokutshintsha ibhalansi emhlophe yesithombe sokutshulwa kwi-RAW usebenzisa isofthiwe yokuhlela umfanekiso. Ezinye iikhamera ze-smartphone ziqala ukunikela ngefomathi ze-RAW kunye ne-JPEG.
Enye into engeyiyo yokudubula kwi-RAW yindawo enkulu yokugcina indawo efunekayo, eya kugcwalisa imemori khadi ngokukhawuleza. Enye into onokujamelana nayo ne-RAW kukuba awukwazi ukuyivula ngeentlobo ezithile zokuhlela umfanekiso okanye ukujonga isoftware. Umzekelo, iMicrosoft Paint ayikwazi ukuvula iifayile ze-RAW. Ininzi imele iiprogram zokuhlela umfanekiso yodwa ivule iifayile ze RAW.
TIFF
I-TIFF ifomatic compress which does not lose any information about data photo, okanye. Iifayile ze-TIFF zikhulu kakhulu kumlinganiselo wedatha kuneefayile ze-JPEG okanye ze-RAW. I-TIFF ifomati eqhelekileyo kwimifanekiso yokupapasha okanye ukucinga kwezonyango kunokuba i-digital photography, nangona kukho iziganeko apho abafaki beefoto abaqeqeshiweyo banokuba neprojekthi apho ifomati yefayile ye-TIFF iyadingeka. Iikhamera ezimbalwa zikwazi ukurekhoda kwi-TIFF.
Indlela yokusebenzisa i-JPEG, RAW, ne-TIFF
Ngaphandle kokuba ungumfoto wezakhono oza kwenza iziprintshi ezinkulu, ukulungiswa kwe-JPEG ephezulu kukuza kuhlangabezana neemfuno zakho zedatha yezithombe. I-TIFF kunye ne-RAW zithwele abantu abaninzi beefoto, ngaphandle kokuba unesizathu esithile sokudubula kwi-TIFF okanye i-RAW, njengokuba kufuneka ukulungiswa komfanekiso ochanekileyo .
