And to answer your question on process, from a photographer.
Firstly, a discussion on what sort of shoot the client wants, including time, location, vibe. Then, a contract! There seems to be a lot of fear here about images being shared online without consent and that absolutely 100% SHOULD NOT happen, and a good photographer should give you the choice of whether you wish images to be shared on the photographers portfolio, and no absolutely means no and should be respected. And consent to share images can be withdrawn at any time and should also be respected. But it is important to remember that once an image is online, you lose control of that image even as the subject or the original creator.
personally, I always send a guide to my clients giving an outline of how many outfits, what sort of outfits will work well depending on the location chosen, what ‘preparation’ you can do (and that absolutely does not include dieting or avoiding certain food groups, or not eating on the day) amongst other things.
on the day of the shoot, the client just turns up and has an absolute blast! I will help choose outfits from the selection based on what the client feels amazing in, and based on my experience as a photographer. You should never have to worry about how to pose, most of my sessions are spend rolling around on the floor, leaning up against walls, just demonstrating poses, and if something doesn’t feel good for the client, or they aren’t comfortable, we just move on to something else instead!
so from my opinion, as a photographer AND as someone who has done many a photoshoot myself as a client, do the photoshoot!
