Yingakho ukugreda kombala kuyindlela ephelele ngokwakho. Ukuvezwa kwenhloso noma inhloso ehlobene ngokuqondile nezifiso zengcweti kungathatha ithuba lokuhlelwa kombala ukuze kufinyelelwe umphakathi ngendlela ephathekayo neqondile. Kodwa kulabo abangazi kahle le nqubo, kungcono ukuqonda ngezibonelo nezincazelo zokusetshenziswa kwayo.
Okokuqala nje, eyodwa isithombe esifanayo Ingabonwa ngezindlela ezahlukene ngokuya ngokwakheka kwendawo (izakhi nokuhlelwa kwazo), noma ngemibala egqanyisiwe. Isithombe senyoni yokuzingela emnyama nemhlophe ayifani nokuthi imibala icacile futhi ikhanya. Umqondo wemvelo yabazingeli kanye nempango, isici esingenangqondo. Yonke into idlala indima yayo ngokwendlela umthwebuli wezithombe anquma ngayo ukubonisa ukuthwebula kwakhe. Yingakho uma usebenzisa ukugreda kombala ukhiye uwukuqonda ububanzi bawo nokwazi izinhloso esinazo ngezithombe zethu.
