I have read a number of articles and seen a few YouTube videos about going out taking photographs with non-photographer friends or family members. They all talk about getting these people to pose for you or getting them to scout for shots to give you a helping hand to make the outing fun for all.
Here's my personal experience
Everyone around me knows about my passion for photography and how I almost always have my camera with me. Unfortunately, apart from my teenage daughter, none of these people are into photography. Now this leads to a couple of problems.
Firstly, the only kind of portrait photography that I do is candid, and so the idea of getting others to pose for me is pretty much out of the question. That said, it doesn't mean that I won't take any photographs of others, I just do it when they don't expect it. This works outs quite well on most occasions because almost all the people I go out with don't like posing for photos. And I'm pleased to say that when I take candid shots of these people, they have liked the results. So, maybe it isn't such a negative aspect.
Secondly, and for me this is the big sticking point, is time. I think that those of us who are serious about taking photographs like to spend some time finding the right composition and making sure our settings are right. In my opinion, this problem exists in all situations, from street photography to landscapes. The reason being is that you have to break away from the non-photographer people you are with to compose and shoot your scene. During that time your companions carry on walking, or whatever they are doing, and you have to play catch-up. Even if they are sitting in a coffee shop while you go off on your own, in the back of your mind there is that time pressure that you have to get all your shots done quickly and get back to them. And if you keep them waiting they'll soon let you know about it. While rushing may not lead to terrible photography, it certainly isn't conducive to great photography.
A like-minded person
My daughter has had a DSLR camera for a couple of years, and spending time with her is a completely different experience. We bounce ideas off each other, help each other when we can and most importantly, give each other time to take the photos we want to take. The whole experience is fun, relaxing and creative.
I love my non-photographer friends and family very much, but I've come to learn that it's just best to leave my camera at home when I go out with them.
