Ukuze lokhu akwenze ngokunemba okukhulu, shot phambili ngenhloso ngaphandle ezinzile: ngakho uyokwazi ukuqeda umsindo nezingahlobene nendaba vibration.

Inselele ebalulekile indlela ukuhlola SLR ikhamera ngokuthenga, kuyoba ngokudubula ezimweni ukukhanya ongaphakeme futhi Macro.

In the mode yokugcina, ikhamera kumele nakanjani kusikisela into isuswe ngu 10-20 cm. Uma kungaqali, futhi uyazi ukuthi kule modi izosetshenziswa njalo ngokwanele, kufanele abheke kwenye indawo. ukuqinisekisa Njalo ukuthi ikhamera kahle kusikisela focus egumbini ovuthayo ngumuntu izibani ezivamile incandescent.

Ngithemba lesi sihloko eye yakusiza ukuba ufinyelele ufunde kabanzi mayelana nendlela ukuhlola SLR ikhamera uma uthenga.
