Enye yezinto ezintsha ezifike nge-Android 5.0 Lollipop kwaba ukuhambisana komdabu ku-Android ngefomethi yesithombe engu-RAW. Kancane kancane, abakhiqizi be-smartphone abahlukene bebelokhu behlanganisa ukuhambisana nale fomethi kumakhamera wamaselula abo ahlukene. Kodwa-ke, kungani kufanele udubule izithombe ze-RAW uma iselula yakho ihambisana? Yiziphi izinzuzo eziyinhloko?
RAW vs. JPEG
Ngaphambilini, lokhu bekuyindida eyavela kuphela kumakhamera we-DSLR asezingeni eliphezulu. Kamuva ifomethi ye-RAW yaze yafinyelela kumakhamera ahlangene. Futhi manje kungenzeka ukudubula izithombe ze-RAW ngisho neselula ephezulu. Kodwa-ke, kungani kufanele udubule i-RAW? Kunomehluko eminingana phakathi kwefomethi ye-RAW nefomethi ye-JPEG, kodwa sizomane sithi ifomethi yokugcina yenza uchungechunge lokulungiswa kwesithombe futhi isilondoloze uma sesicutshunguliwe, kuyilapho izithombe ezikufomethi ye-RAW zifika zingacutshungulwanga. ulwazi oluhlobene nesithombe esithwetshiwe. Kuchazwe kanjalo, umuntu angase acabange "i-JPEG engcono, akunjalo?" Nokho, uma ungumsebenzisi we-novice, futhi ungafuni ukuhlela izithombe zakho, mhlawumbe i-JPEG iyisinqumo esingcono kakhulu. Kodwa ifomethi ye-RAW iyona enikeza umthwebuli wezithombe amathuba amaningi.
Ukukuchaza, ngizoboleka isibonelo sokuthi sebenzisa lapha umthwebuli wezithombe uPaco Jiménez. ISITHOMBE ESIHLAZA siqukethe ukudla okuluhlaza kanye neresiphi yokulungisa ukudla, kuyilapho isithombe se-JPEG siwukudla osekuphekiwe. Uyini umehluko? Hhayi-ke, esithombeni se-RAW singenza izinguquko ngaphandle kokulahlekelwa yikhwalithi. Njengoba nje besingakwazi ukushintsha iresiphi yokudla ngaphambi nje kokukupheka, noma siguqule isithako esisodwa sibe esinye, esithombeni RAW singashintsha amanani anjengebhalansi emhlophe, ngokwesibonelo. Ngakho-ke, isithombe ebesicabanga ukuthi asihambanga kahle, singaba esinye sezithombe esizikhonzile ngenxa yokuthi singasihlela ngokuhamba kwesikhathi uma sisithwebula ngefomethi ye-RAW.
Ukungalungi kwe-RAW
Kunjalo, ifomethi ye-RAW inezihibe ezithile uma iqhathaniswa nefomethi ye-JPEG enganquma kumakhalekhukhwini. Njengoba sesishilo, izithombe ngefomethi ye-RAW zinolwazi olwengeziwe, ngakho-ke, zinesisindo esiningi. Lokho kusho ukuthi sidinga imemori yangaphakathi noma imemori khadi yomthamo ophezulu uma sifuna ukudubula ku-RAW, noma kunoma yikuphi, ukuthi singakwazi ukudubula inombolo encane yezithombe kule fomethi kune-JPEG. Ukuthi, kwamanye amaselula anganiki ithuba lokukhulisa inkumbulo ngekhadi le-MicroSD, kuyinto ebalulekile. Iselula enekhamera engu-16 megapixel noma engu-20 izokhiqiza izithombe ezingu-RAW ezizothatha isikhala esiningi. Futhi uma une-32 GB kuphela, ngaphandle kokuthi kungenzeka ukwandisa inkumbulo, ukusebenzisa ifomethi ye-RAW akuyona into engcono kakhulu.
Nokho, akuwenzi umqondo ongako ukuthi ungayisebenzisi uma une-smartphone esezingeni eliphezulu. Phela, uma une-smartphone yalelo zinga, phakathi kwezinye izinto, ngoba inekhamera yekhwalithi ephezulu. Uma unekhamera yale khwalithi, kuvamile ukuthi ufune ukuthola izithombe ezinhle kakhulu ngangokunokwenzeka. Futhi ngaphezu kwalokho, uma nganoma isiphi isikhathi ucabange ukushintsha ikhamera yezinga eliphezulu ngekhamera yeselula, ukudubula izithombe ku-RAW, uma iselula yakho ihambisana, kuzoba ukhiye ukuze izithombe ezikuselula yakho zifane kakhulu. ezithombeni ongazithola ngekhamera ye-DSLR noma ikhamera engenazibuko.
Ngakolunye uhlangothi, kungenzeka ukuthi isithombe RAW eduze kwesithombe se-JPEG singabonakala siyisithombe esibi kakhulu, noma silula. Khumbula ukuthi lokhu kungenxa yokuthi kudinga inqubo yokulungisa. Uma ungazi lutho mayelana nokuthatha izithombe futhi ungafuni ukwenza izinto zibe nzima, mhlawumbe ukuthwebula nge-JPEG kungaba inketho enhle kuwe.
Nakanjani. Kufanele uthwebule i-RAW ukuze uthole ikhwalithi engcono kakhulu ezithombeni ngeselula yakho, nakuba kufanele ucabangele indawo ezikuzo lezi zithombe, okungaba bucayi uma unememori yangaphakathi enomthamo ophansi, futhi awukwazi ukuyikhulisa yememori khadi ye-microSD.
