a bunch of years ago, not sure how many, maybe 5 or 6 ?
frank petronio was posting a lot of his nudes and was asked questions
about photographing nude models. he spoke about the logistics
and equipment a little bit but he also talked about state of mind.
before he even picked up a camera to photograph them,
he put himself out there in the same vulnerable position models were in.

i wish i could find the thread to post a quote from the conversation,
(if someone knows were it is, please post a link )
because i might get some of it wrong, but he pretty much said he
went to an art school and volunteered as a nude model in life drawing
and (?) photography classes. he did this so he knew what his subjects
were dealing with. so he could have some sort of understanding about what
it was like to be totally vulnerable ...

i don't shoot nudes, i have plenty of other things to keep me occupied
but for those who do shoot ( have shot, might shoot ) nudes have you
and modeled yourself, amongst strangers or do you just photograph models
and not worry about how vulnerable &c they may be. i'm not talking about edgy
photography, things that may turn heads or get called out as being one thing or another
i mean pretty much any work.
