then you give them bad shots, this is not a fair exchange.
ts - why must shoot model right away?
are you saying that your mother , your sister, your male friends even, are not humans?
portraits , the logic is the same. the only difference might be poses, etc.. even family members can be used as subjects to learn.
if you are merely using this to socialise, then join the mass photoshoots, that might be more of your flavour, pay money to get people to smile at you.
if not, start from basics, don't pay money first..
