Does photography posing coaching exist for adults?

If so please, please, please help me find it 😭

I photograph appallingly. It’s a running joke in my house. I look absolutely awful. Everyone calls me Chandler (friends reference, iykyk). The frustrating thing is I don’t think I look quite this bad in real life so I think it’s a technique problem rather than just a my face and body problem?

I’m at a stage in my career where I’m attending a lot of industry events and every single tagged photo of me is mortifying. I look like a very old, fat (often) shiny thumb that has just emerged from under a bridge and scuttled into the event to interact with real humans. I am at the point of wanting to dive under the nearest table whenever a photographer approaches.

I’ve tried practising poses at home in the mirror and I cannot get it right. I look alright in about 20% of them. Then when there’s a camera on me for real I turn into this: 😬👍🏽

Does photography posing coaching actually exist for adults? Not modelling, or for influencers, just “how to stand like a normal human woman when a camera points at you” coaching. Ideally in person rather than a YouTube rabbit hole. I’m in London, UK.

If it matters: it’s mostly standing receptions and networking events, so group and candid shots rather than formal portraits. Though a LinkedIn headshot that doesn’t make me look like I’ve recently wrestled a badger and scared it off with my face would also be a bonus.

I’m desperate for help. Tbh it would also be nice for my personal life. Both my kids are agency signed models, my husband was signed in his 20s… and then there’s me. I hide away whenever anyone tries to take a photo of us all or when they do, I have a little cry in secret afterwards because I’ve ruined a lovely photo of my family by being in it. I’d love to have one or two photos from my kids’ childhood where it doesn’t look like a crazed thumb lady who has infiltrated a nice, normal family.

Any recommendations or advice genuinely appreciated. I am desperate and can’t quite describe how down this is getting me.

Thank you so much.
