Ochwepheshe bathi kungenzeka ukuthi uthole izithombe ezisezingeni eliphezulu nge-smartphone, inqobo nje uma wazi ukuthi ungayithola kanjani. Kungakho sizoqala ngalolu chungechunge oluncane lwezihloko ezintathu lapho sizochaza khona izici ezintathu ezibalulekile kulokho esikubiza ngokuthi ukuchayeka ezithombeni, futhi ezinquma cishe yonke into uma kuziwa ekutholeni isithombe esihle. Ake siqale ngokukhuluma ngeShutter Speed.
1.- Izilawuli ezenziwe ngezandla
Into yokuqala nebalulekile ukuthi i-smartphone yethu isinika ukufinyelela kulezi zilungiselelo, ezintathu eziyinhloko, lezo zesivinini sokuvala, i-ISO, ne-Aperture. Uma kunjalo, kungenzeka ukuthi uhlelo lokusebenza olufaka i-smartphone njengezinga elijwayelekile selivele lisivumela ukuthi siguqule lezi zilungiselelo. Ukwenza lokhu, yebo, kungenzeka kakhulu ukuthi kufanele sisebenze imodi yekhamera yezandla.
2.- Siyini isivinini se-shutter?
Uma uthatha isithombe, kune-shutter evulekayo, ivumele ukukhanya kudlulele kwinzwa, bese ivala. Kukhona isivinini se-shutter esinquma ukuthi isivalo sizovuleka isikhathi esingakanani, ngakho-ke, ukuthi inzwa izothatha ukukhanya isikhathi esingakanani, noma izothwebula isithombe esiphambi kwethu. Ngokusobala, ngesikhathi se-shutter eside, sithola nesithombe esicacile, noma esinokukhanya okwengeziwe.
3.- Isivinini se-shutter silinganiswa kanjani?
Kodwa-ke, ukuze wazi kahle ukuthi yisiphi isivinini se-shutter ozosisebenzisa, udinga ukwazi ukuthi lesi silungiselelo sivezwa kanjani. Ngokuvamile kuba ingxenye yesekhondi. Kwesinye isikhathi kungaba umzuzwana, noma kube yinde, kepha sizoyibona njengengxenyana yomzuzwana. Lokho kusenza sihlale sibona into yalolu hlobo: «1/125», «1/250», okungeyona into engaphezu kwe-«umzuzwana owodwa, ihlukaniswe ngama-250». Uma inombolo yesibili inkulu, isikhathi sokuvala siba sifushane.
4.- Ungayisebenzisa kanjani isivinini se-shutter ezithombeni zakho?
Vele, manje kuza into ebalulekile, futhi lokho kuwukwazi ukuthi lesi sivinini se-shutter kanye namanani aso ahlukene senzelweni.
Isivinini se-shutter esinensayo, noma side kakhulu: Ake sithi sizosetha ileveli yesivinini se-shutter ende kakhulu, njengokuthi "1/20". Lokhu kusho ukuthi i-shutter izovuleka isikhathi eside. Izobamba ukukhanya okukhulu. Lokhu kuhle kakhulu ezimweni zokukhanya okuphansi, noma ebusuku, lapho iselula ingasathwebuli ukukhanya okwanele. Kodwa futhi kunenkinga ngalokhu. Uma okuthile kuhamba phambi kwethu, noma sihambisa iselula, ukunyakaza kuzothathwa, futhi kuzovela isithombe "esinyakazayo" noma esinyakazayo. Lokho kusho ukuthi ngesivinini esiphansi kakhulu, sizodinga i-tripod. Singadubula ngokushesha kangakanani ngaphandle kokudinga i-tripod? Linga ngeselula yakho ukuze uthole.
Isivinini se-shutter esheshayo, noma esifushane kakhulu: Kodwa kungase futhi kube usizo ukusebenzisa isivinini sokuvala esisheshayo, noma esifushane kakhulu. Isibonelo, "1/1000". Yini esingafuna ukuyisebenzisela lolu hlobo lwesivinini se-shutter? Sesishilo ukuthi inkinga ngalokhu okungenhla ukuthi izakhi zesithombe ziyanyakaziswa. Uma esikufunayo kuwukumisa izakhi esithombeni esinyakazayo, njengesilwane esifuywayo, noma njengezingane ezincane ezigijimayo, sidinga ukudubula ngokushesha okukhulu. Futhi, ukuzama ngekhamera yakho ukuthola ukuthi yimaphi amaleveli afanelekile kuzoba ngcono kakhulu.
Konke lokhu kwenzelwa ini?
Ukuvezwa esithombeni yikho konke. Kungashiwo ukuthi yikho okunquma izinga lokukhanya esithwebula ngalo isithombe. Futhi ukuchayeka kuthonywa isivinini se-shutter, i-ISO ne-aperture. Sesike sakhuluma ngesici sokuqala, futhi kulo lonke leli sonto sizokhuluma ngezinye ezimbili. Ziyizakhi ezaziwa kakhulu ezithombeni. Noma iyiphi ikhamera isinika inketho yokusebenzisa lezi zilungiselelo ezihlukene, kodwa bekungenjalo ngamaselula kuze kube yizikhathi zakamuva. Manje njengoba sesinazo lezi zinketho, kuhle ukwazi ukuthi iyiphi yalezi zakhi, nokuthi zisetshenziswa kanjani, kanye nokubona ukuthi zithinta kanjani izithombe zethu esimweni ngasinye.
