I would do the same too to gain experiences. I try applied to several famous magazine for the photographer assistant or helper. So I can learn to be the professional. But no one reply, I guess many people want to do it.
Well would it be a good idea to look for not so famous places ?
Like asking at photo studios... or wedding photographers...
it might be possible to just go to places where people photograph for weddings and have a look at what the photographer does...
there are also tutorials on the internet.
Well important may be to know the own equipment... so settings can be changed reliably...
and knowing where the limits are... concerning light, movement etc...
having a good eye for spots and moments...
