IMO, there isn't really a way to tell. But I only know 2 types of photographers, those that makes good/great pictures or those that take snapshots.
Those that shot great pictures may not necessary mean that they are pro but maybe because (*please dun flame me for this*)
1) Luck, Just happen to click the shutter when it happens
2) Lots of considerations about lighting, composition etc
If you are shooting most great photos because of reason 2, you probably have reach a certain pro/master stage.
btw, if you are really checking Kei's camera's menu for the option, you shdnt be worrying about this question. (you shouldn't even be concern about this question in the no matter which stage of learning you are at. What matter most is knowing how to take Great shots!)
@____@ i dun even know if i'm a beginner or intermediate level now. i started learning photography 3years ago. that time i dun have enough money to get a dslr. so i stopped learning photography. only recently i saved enough to get a entry level dslr. now i'm thinking if i got the wrong dslr or not....
I don't know how well you make photographs, but from your statements and apparent obsession with equipment and 'status', you sound very much like a beginner.
Then again, we're all beginners in some ways. Skill-wise, ability-wise, you are where you are. Move on and grow from there.
