Posing tips for senior photos!

So my experience with senior photos haven't been the best! Some of the clients that I have had seem to rely on the camera to make the photo great. I try to get them to loosen up by having them be silly or having them try new things, but it seems like it hasn't been working. Can you guys give me tips on how to get clients to try a variety of poses and how to make them more comfortable. Thank you!

Use Flickr, Instagram, Pinterest etc. Build a library of male/female/couples/gr​oups etc and save them for easy access. I also struggle here because I don't shoot much and have not shot portraits in a while. As I am getting back into it more now, I have a large selection of picture ideas to choose from.
Grab a few books on posing and learn why some pose the way they do...for flattering light, moody light, slimmer, broader, more feminine etc.
That and practice.

Practice recreating poses that you like in front of a mirror - both male and female. I think that helps a bit when guiding someone else into it, and then moulding it to what you want.

There's also a good posing app by Sia Mendo that I would recommend when you're stuck for inspiration.

I find that subject look for confidence. They want to know you are making them look good. If you are nervous/fumbling/unsur​e they can usually tell and they get uneasy.

i try to get them to loosen up and have fun even if i have to look like an idiot to get them to laugh. I also encourage my clients to look at the above mentioned sites for examples so they know what kind of images they want. I even go as far to encourage them to tag me in pins if its something they really like and want to shoot. Then i take it from there. There are staples that i do in every shoot, kinda my thing that i adapt to them. key is to get to know them
