Ibanga lento lincane kunobude obuqondile besibuko esigobile (s < f)
Ngokusekelwe ekubalweni ku- isithombe sesibuko esigobile Kungaphethwa ngokuthi uma ibanga (ama) lezinto lincane kunebanga eliqondile (f), khona-ke izakhiwo zezithunzi ezibukweni ezigobile ngu:
– UMaya usho ukuthi ukukhanya akudluli emthunzini
- Iqonde noma ingagxilile
– Uma into ikude kakhulu nesibuko esigobile, usayizi wesithombe uba mkhulu.
– Uma into ikude kakhulu nesibuko esigobile, isithombe sikude kakhulu nesibuko esigobile.

Ukuze uqonde isithombe sento eyakhiwe yisibuko esigobile, hlola isibonelo esilandelayo sombuzo kanye nengxoxo. Kulo mbuzo, kucatshangwa ukuthi into ikude kakhulu nesibuko esigobile, bese kuchazwa ukwakheka kwesithombe sento ngesibuko esigobile , ibanga lesithombe esisuka esibukweni esigobile kanye nokukhulisa isithombe esenziwe yisibuko esigobile .

Ake sithi isibuko esigobile sinobude obuqondile obungu-20 cm. Chaza ukwakheka kwesithombe bese unquma ibanga lesithombe kanye nokukhulisa isithombe uma:
a) ibanga lento lincane kunebanga lendawo yokugxila (s < f)
b) into itholakala endaweni egxile esibukweni (s = f)
c) into iphakathi kwephuzu eligxile kanye nesikhungo sokugoba kwesibuko (f < s < R)
d) into itholakala endaweni ephakathi nendawo yokugoba kwesibuko (s = R)
