Nakuba usayizi wefayela ngokwengxenye uncike ekutheni uthathani, izithombe Eziluhlaza zivame ukuba zinkulu kakhulu ngosayizi kunamafayela e-JPEG. Lokhu kungase kube okuphindwe kabili noma kathathu ubukhulu, noma mhlawumbe ngisho nayisithupha noma kasikhombisa - futhi lokhu kunezihibe eziningi.
Makhulu kangakanani amafayela aluhlaza uma kuqhathaniswa ne-JPEG?
Amafayela RAW makhulu kunama-JPEG njengoba agcina idatha eningi kakhulu. Ikhamera engu-16-megapixel izoletha ifayela elicishe libe ngu-16 MB RAW. Amafayela angu-RAW angamafayela okufunda kuphela. Konke ukuhlelwa kwesithombe kwenziwa kufayela le-sidecar futhi ekugcineni kulondolozwe njenge-TIFF, JPEG, noma olunye uhlobo lwefayela lesithombe.
Lingakanani ifayela lesithombe se-RAW?
Usayizi wefayela elingu-RAW uncike kusayizi wenzwa, nokuthi ikhamera yakho iyikhamera ye-MFT, APS-C, enohlaka olugcwele noma yefomethi emaphakathi. Amafayela amaningi angu-RAW anosayizi ophakathi kuka-20 – 40 MB ngefayela ngalinye.
Ingabe i-Raw ingcono ngempela kune-JPEG?
Isithombe esingu-RAW siqukethe ububanzi obuguqukayo obubanzi kanye ne-gamut yombala uma kuqhathaniswa nesithombe se-JPEG. Ukuze uthole ukugqama nokuthola ithunzi lapho isithombe noma izingxenye zesithombe zivezwe kancane noma zivezwe ngokweqile, isithombe esingu-RAW sinikeza amandla angcono kakhulu okutakula uma kuqhathaniswa ne-JPEG. Ukulawula okuhle namandla okulungisa.
Ingabe kufanele ngidubule nge-RAW noma i-JPEG noma kokubili?
Ngakho kungani cishe wonke umuntu encoma ukudubula i-RAW ke? Ngoba angamafayela aphakeme nje. Nakuba ama-JPEG elahla idatha ukuze akhe usayizi wefayela omncane, amafayela e-RAW agcina yonke leyo datha. Lokho kusho ukuthi ugcina yonke idatha yombala, futhi ugcina yonke into ongayenza ngendlela yokugqamisa nemininingwane yesithunzi.
Ingabe ukuguqula i-RAW iye ku-JPEG kulahlekelwa ikhwalithi?
Ingabe ukuguqula i-RAW iye ku-JPEG kulahlekelwa ikhwalithi? Ngesikhathi sokuqala ukhiqiza ifayela le-JPEG efayeleni elithi RAW, ungase ungawuboni umehluko omkhulu kwikhwalithi yesithombe. Nokho, uma ulondoloza izikhathi eziningi isithombe se-JPEG esikhiqiziwe, uzoqaphela nakakhulu ukwehla kwekhwalithi yesithombe esikhiqiziwe.
Kungani amafayela ami aluhlaza evela njenge-JPEG?
Okuthile kusistimu yakho okuphazamisa ingqondo yakho ngokufihla isandiso se-RAW (CR2 IIRC) futhi usibonise njengenye i-JPEG. Uma ufaka okuthile ukuze utolike amafayela akho e-RAW, ngingayikhipha bese ngithola i-Adobe Camera RAW noma i-Lightroom (uma nawe ufuna ukuphatha izithombe zakho).
Iyini i-JPEG vs RAW?
Ukucutshungulwa kwe-JPEG okusetshenziswa yikhamera kuklanyelwe ukukhiqiza isithombe esibukeka kahle ngaphandle kwekhamera, futhi lokhu kucubungula akukwazi ukuhlehliswa. Ifayela elingahluziwe, ngakolunye uhlangothi, licutshungulwa nguwe; ngakho unganquma ukuthi isithombe sizobukeka kanjani.
Imele ini ifayela le-RAW?
Ifayela elingahluziwe iqoqo ledatha engacutshungulwanga. Lokhu kusho ukuthi ifayela alishintshwanga, licindezelwe, noma lisetshenziswe yikhompuyutha nganoma iyiphi indlela. Amafayela aluhlaza avame ukusetshenziswa njengamafayela edatha izinhlelo zesofthiwe ezilayisha futhi zicubungule idatha. Uhlobo oludumile lwefayela eluhlaza ithi “Ikhamera RAW,” ekhiqizwa ikhamera yedijithali.
Ingabe izithombe ezingavuthiwe zingahlelwa?
Izinto eziyisisekelo zokuhlela izithombe ezingu-RAW
Yebo, ufunda lokho kwesokudla: ifayela le-RAW alikwazi ukuhlelwa noma ukucutshungulwa kunoma yisiphi isihleli sesithombe. Abahleli be-RAW bakuvumela ukuthi ulungise cishe noma yini ongayicabanga: ukuchayeka, ubukhali, umbala, umsindo, nokuningi.
Ingabe kufanele uhlale udubula nge-RAW?
Kufanele njalo uthwebule uluhlaza uma uthatha izithombe esimweni lapho kunzima khona ukulawula ukuvezwa okugqamile. Efayelini elingahluziwe, ungakwazi ukubuyisela imininingwane kokubekwe obala okuvezwe ngokweqile ukuze kuqedelwe okumhlophe nokuhlenga amashothi angenakusebenziseka uma kungenjalo.
Ingabe abathwebuli bezithombe abangochwepheshe bathwebula nge-RAW noma i-JPEG?
Abathwebuli bezithombe abaningi abangochwepheshe bathwebula nge-RAW ngoba umsebenzi wabo udinga ukucubungula okuthunyelwe kwezithombe zekhwalithi ephezulu ukuze ziphrintwe, ezentengiso noma ezishicilelwe. Enye into okufanele uyiqaphele ukuthi i-JPEG ayivamisile ukusetshenziselwa umsebenzi wokuphrinta njengoba ilahleka kakhulu. Amaphrinta akhipha amafomethi wefayela elingalahleki (TIFF, njll.) anemiphumela engcono kakhulu.
Kungani i-JPEG iyimbi kakhulu?
Lokhu kungenxa yokuthi i-JPEG iyifomethi yokucindezela elahlekile, okusho ukuthi eminye imininingwane yesithombe sakho izolahleka uma igcinwa ukuze kugcinwe usayizi wefayela ophansi. Amafomethi okucindezela alahlekile akwenza kungenzeki kuwe ukuthola idatha yoqobo, ngakho-ke akugcini nje ukuguqulwa isithombe, kodwa umphumela awubuyiseleki emuva.
Ingabe okuluhlaza kubukhali kune-JPEG?
Ama-JPEG asuka kukhamera afakwe ukucijiswa kuwo, ngakho-ke azohlala ebonakala ecijile kunesithombe esingacutshunguliwe, esinedemoyisi ye-RAW. Uma ulondoloza isithombe sakho RAW njenge-JPEG, umphumela we-JPEG uzohlala ufana ncamashi nesithombe RAW.
Ingabe kufanele uthwebule i-RAW ne-JPEG?
Ingabe kufanele udubule nge-RAW, JPG, noma kokubili? Konke kukuwe. Umthwebuli wezithombe ohambayo owenza ukuphrinta kobuciko obuhle cishe uzodinga ifayela le-RAW futhi angasebenzisi i-JPEG. Yonke leyo datha ibalulekile ukuze uthole okuningi esithombeni ozosiphrinta ngamafidi amahlanu ububanzi.
Kungani kungafanele udubule eluhlaza?
Lokho kungenxa yokuthi ifomethi ye-RAW iyisethi yedatha, kunesithombe. Ngakho-ke noma ulungisa idatha kusofthiwe yakho yokuhlela, isazokhumbula idatha yoqobo ephume ngokuqondile kunzwa yekhamera yakho. Ngokuphambene nalokho, into eyodwa okufanele uyikhumbule ngama-JPEG - noma yikuphi ukuhlelwa kwesithombe se-JPEG kuyalimaza.
