I would not consider discussing shoot concepts to be “creepy” as long as the shots you are setting up are not “creepy”… :)
I believe the photographer has the control, in the end, to execute his vision… but the team must be on board. While its important to get team feedback and shoot what they’re interested in getting for their books, you have to be the one who brings it to life so it must be your vision.
The better you get, the less you will want other people to tell you what to shoot. Its not rolling yet because it only comes with time, exposure to inspiration, practice from testing, and then criticism.
Personally, I don’t like being asked to meet before hand to discuss the shoot (sounds like a date), I don’t like long calls (we are not friends, at least not yet). The best thing you can do when communicating ideas to the model is send example images and an email explaining what you want to do at your shoots.
Well, seeing how I’m a model and not a photographer I cant say I have any technical answers for you…LOL
