I'm very camera shy, as are both my parents and one of my brothers. It's ingrained in me, but I don't see that as something I should want to fix. I have no need to be more confident in front of the camera.
In spring I joined a women's running group. I did so as I'm embarrassed about running alone due to my weight and I just generally hate being conspicuous; also because I wanted to have company for dark winter running. They have a closed FB group but it's a large one and on a small town, lots of people have links to it.
It really annoys me that there's frequently a photographer taking warm-up and mid-run snaps which then get uploaded to the FB page. Over the summer, a much smaller group of us went running, and while I was really pleased with how well I ran, someone took a pic from behind of me running across a field and again, put it on FB. I look awful thundering along in my Lycra, and although that specifically isn't the reason, it really embarrassed me and I haven't been back since. It's made me feel worse about running alone, and again, I haven't done that since either.
I was going to get back into it this week, life having quietened down a little, but didn't have a Halloween fancy dress outfit I hand 
so didn't bother. Glad I didn't as there was photo after photo of runners and teams. I don't want to be picture sweaty, red-faced and Lycra clad, thanks! I really don't think I'll bother going back now. I'll probably just keep myself to myself in the ladies only gym over winter.
There's also a park run fairly close by. I've been put off joining in that due to the incessant photography. I did raise this with te organisers and they suggested I make myself known and they wouldn't take my picture. However, how is a random photographer going to identify me among hundreds of runners? Another thing is a 10k that I was going to sign up for. But I just bloody know that the camera will be out and it'll be up on FB by the afternoon.
Ok this is a personal moan, but why is it just assumed that everyone wants their photo taken? Of course I could opt out if I wanted to, and ignore the 'come on, get in the photo' demands, but I don't want to mark myself as the awkward one. Why do we private types have to do that? Why can't there be more of an opt in mentality about having pics taken and uploaded to FB?
