If you have a proven portfolio of good photos showing a keen eye for a shot, some interesting observational skills, and great PP too - then maybe
For me though - for a 2nd shooter's images to be of any use at all they must sit well with my own, that means shooting what I tell you & how I tell you
For example - I don't like images shot on a tilt, so if you handed me 100 FAB shots all tilted I'd probably bin the lot of them. I rarely shoot anything above f5.6 and mostly f4 or below, so if you showed me some FAB images all shot at f16 I'd probably bin them all. I shoot speeches with OCF via a TTL cable, if you shot them in any other way... well you can see where that's going
So no - having the use of some photos that may be great but will look totally out of place in my albums is of no use whatsoever - and if you can't prove to me that you're a very good technically competent photographer I'm not ever going to entertain you
I hope that doesn't just sound harsh, but it is reality
If you offered to merely assist carrying stuff and being a VALS then that'd be much more useful, and if you did that right and we got on well too, then you could bring a camera as well probably. If I still didn't like your photos for MY use (they could be FAB photos) then I may well still not use them, you shouldn't get upset about that as all it'd mean is that we don't have the same style
IMHO you would learn far more and more quickly assisting than trying to take your own shots - oh, and you NEED to work with several togs too ideally and just pick whatever suits you best from them all
