Isikhali Esiyimfihlo Sabathwebuli Zithombe: Ukugxila Kwenkinobho Emuva Ngezithombe Ezicijile

Uma ufundile amabhulogi wokuthwebula, ukuhlanganyela kwizithangami zezithombe, noma ukuhlanganyela nabanye abathwebuli bezithombe, kungenzeka ukuthi ulizwile igama “Ukugxila kwenkinobho yangemuva” okukhulunyiwe. Kungenzeka ukuthi awuqiniseki ukuthi imayelana nani, noma mhlawumbe uzwile ukuthi ungathola izithombe ezibukhali ngokugxila kwenkinobho emuva kodwa awunasiqiniseko sokuthi kanjani. Ungaze uzibuze ukuthi ngabe kuyinto okudingeka uyenze noma cha. Lokhu okuthunyelwe kuzokudiliza konke lokho.

Okokuqala, yini ukugxila kwenkinobho yangemuva?

Kalula nje, ukugxila kwenkinobho emuva usebenzisa inkinobho ngemuva kwekhamera yakho ukufeza ukugxila kunokusebenzisa inkinobho yokushutha ukugxila. Kuzoya ngohlobo lwekhamera nemodeli yakho ukuthi iyiphi inkinobho oyisebenzisela lo msebenzi. Ngidubula iCanon. Kuthathwe ngezansi omunye wemizimba yami yeCanon; inkinobho ye-AF-ON ngaphezulu kwesokudla isetshenziselwa inkinobho yokubuyela emuva egxile (i-BBF) kuyo yomibili imizimba yami. Amanye ama-Canon asebenzisa inkinobho ehlukile, kuya ngemodeli. Imikhiqizo ehlukile nayo ine-setups ehluke kancane, ngakho-ke thintana nencwajana yekhamera yakho ukuthola ukuthi iyiphi inkinobho esetshenziselwa ukubheka inkinobho emuva.

Yini ehlukile ngokugxila kwenkinobho yangemuva (i-BBF) futhi inganginikeza kanjani izithombe ezibukhali?

Ngokobuchwepheshe, ukusebenzisa inkinobho yangemuva ukugxila kwenza into efanayo ncamashi nenkinobho yokushutha: iyagxila. Ayisebenzisi noma iyiphi indlela ehlukile ezokunikeza izithombe ezibukhali. Phezulu, zombili izinkinobho zenza into efanayo. Kunezinzuzo ezimbalwa ekugxileni kwenkinobho emuva - futhi zingakusiza ukuthi ubukhali. Inzuzo enkulu ye-BBF ukuthi yehlukanisa inkinobho yokushutha ekugxileni. Uma ugxila kunkinobho yokushutha, nobabili nigxile futhi nidedela i-shutter ngenkinobho efanayo. Nge-BBF, le misebenzi emibili yenzeka ngezinkinobho ezihlukile.

Ungasebenzisa i-BBF ngezindlela ezahlukahlukene zokugxila. Uma usebenzisa imodi eyodwa yokudutshulwa / imodi eyodwa, ungacindezela inkinobho yangemuva kanye ukukhiya ukugxila nokugxila kuzohlala kuleyo ndawo ethile uze ucindezele inkinobho yangemuva futhi ukuze uphinde ucindezele. Lokhu kunenzuzo uma udinga ukuthatha izithombe eziningi (ezinjengama-portraits noma ama-landscapes) ezinokwakheka okufanayo nendawo yokugxila. Akudingeki ukhathazeke ngokubheka kabusha kwelensi isikhathi ngasinye lapho uthinta inkinobho yokushutha; ukugxila kwakho kukhiyiwe uze unqume ukukushintsha ngokucindezela inkinobho emuva futhi.

Uma usebenzisa imodi ye-servo / AF-C, ukugxila kwenkinobho yangemuva kungasiza kakhulu. Uma usebenzisa le modi yokugxila, imoto yakho yokugxila kwelensi isebenza njalo, izama ukugcina ukugxila esihlokweni osilandelayo. Kungenzeka futhi ukuthi udubula isibhamu esithile ngenkathi wenza lokhu kulandelwa kokugxila. Ithi usebenzisa ukugxila kwenkinobho yokushutha futhi ulandelela isihloko, kepha kukhona okuza phakathi kwelensi yakho nesihloko sakho. Ngokugxila kwenkinobho yokushutha, ilensi yakho izozama ukugxila ekuvinjelweni inqobo nje uma umunwe wakho uhlala kunkinobho yokushutha, izithombe zokudubula. Kodwa-ke, uma ugxila kunkinobho engemuva, lokhu akuyona inkinga. Uyakhumbula ukuthi ngishilo kanjani ukuthi i-BBF yehlukanisa inkinobho yokushutha ekugxileni? Yilapho iza kahle kakhulu. Nge-BBF, uma ubona ukuvinjelwa kungena phakathi kwelensi yakho nesihloko sakho, ungamane ususe isithupha sakho kunkinobho yangemuva bese imoto egxila kwilensi izoyeka ukusebenza futhi ingagxili ekuvinjelweni. Usengaqhubeka nokuthwebula uma ufisa. Lapho ukuvinjelwa kuhamba, ungabeka isithupha sakho emuva kunkinobho engemuva uphinde uqalise ukulandela umkhondo kokugxile esihlokweni sakho esihambayo.

Ingabe ukugxila kwenkinobho yangemuva kuyadingeka?

Cha. Kuya ngokuthi kube yinto oyithandayo. Kukhona abanye abathwebuli bezithombe abasizakalayo, njengabathwebuli bezemidlalo nabathwebuli bezithombe zomshado, kepha noma kunjalo akudingeki ukuthi bayisebenzise. Ngiyisebenzisa ngoba ngiyizamile, ngiyayithanda, futhi ngajwayela ukusebenzisa inkinobho yami yangemuva ukugxila. Manje sekuzizwa kungokwemvelo kimi. Yizame ukubona ukuthi uyayithanda nokuthi iyahambisana yini nesitayela sakho sokudubula. Uma ungayithandi, ungahlala ubuyela emuva ekugxileni kwenkinobho yokushutha.

Ngikusetha kanjani ukubheka emuva kwenkinobho yekhamera yami?

Inqubo ngqo yokusetha izohluka ngokuya ngohlobo lwekhamera nemodeli yakho, ngakho-ke kungcono uthintane nencwajana yakho ukuthola ukuthi ungamisa kanjani ukugxila kwenkinobho emuva kwikhamera yakho ethize. Amathiphu ambalwa (ngifunde lokhu ngokuhlangenwe nakho!): Ezinye izinhlobo zekhamera zinenketho yokuba nenkinobho yokubuyela emuva nenkinobho yokushutha igxile ukusebenza ngasikhathi sinye. Qiniseka ukuthi ukhetha imodi ezinikezelwe ngokukhethekile ekugxileni kwenkinobho yokubuyela emuva kuphela. Futhi, uma unerimothi yekhamera engenantambo evumela i-autofocus, kungenzeka ukuthi umzimba wakho wekhamera ngeke u-autofocus usebenzisa i-remove uma une-BBF esethwe kukhamera. Uma udinga ukugxilisa i-autofocus futhi usebenzise irimothi, uzodinga ukushintshela ikhamera emuva ekugxileni kwenkinobho ye-shutter okwesikhashana.

Ukugxila kunkinobho yangemuva akuyona isidingo kepha kuyindlela abaningi bezithombe abayithola ibalulekile. Manje njengoba usuyazi ukuthi iyini nokuthi izuzisa ngani, zama futhi ubone ukuthi ingeyakho yini!
