There is so much to learn when it comes to photography that you can concentrate so hard on one thing, you completely miss everything else. But one thing's for certain, there's nothing more frustrating than being in the heat of the moment and not being able to work out what's going wrong.
That will come about through constant practice. Event photography scares me as I don't like mingling at the best of times. So if it's something you're going to pursue, then you need to be good with people. I seem to remember
@Phil V (I think) saying that he had two personas - Phil the photographer, confident, take charge kind of guy, and Phil the non-photographer, who probably wouldn't go up to complete strangers and boss them about.
I think as others have said, when photographing people, you're not likely to go wrong if you focus on their eyes. And when there's more than one person, constantly shooting at f/1.8 means you'll more than likely only get one person in focus. We've all been guilty of it - me especially when I got an f/1.4 lens. I shot everything at 1.4 and came on here thinking I knew it all and that something was wrong with my kit because a lot of my shots weren't as sharp as wanted.
A few pointers (most considerably less harsh than some on here) and I was at least heading in the right direction. I'm lucky in that most of the photos I take are really just for me, so if I'm happy then all well and good. But as soon as you start taking them for other people, I'd argue that the stakes aren't just a little bit higher, they go up exponentially.
Friends of ours knew I was a keen snapper (I won't use the term photographer) and asked me if I wouldn't mind taking pictures of their wedding. This was before I even had a DSLR. They didn't have a lot of cash, and I explained I only had a point and shoot, but at that point I realised just how important some events are to people and how much pressure there is on you. They were happy with the results (it's hard not to believe you're getting value for money when something's free).
ETA: I've just looked back over the images and while they may have been happy, i wouldn't say they were good. Snapshots, but nothing more.
Certainly now I have 8 more years' knowledge, some better equipment and a little more confidence, I would approach things very differently.
You're not really paying for people's time as such when you hire a photographer, you're paying for their expertise and their results. It may be that you're choosing them for a particular style or look, it may be that you're choosing them because you can guarantee you'll get what you asked for. But in my humble opinion, if you're going to accept any of these jobs, you should explain to them that you're learning and not seek to get paid for time or shots, but accept that the knowledge you gain is more valuable than any money you'd get.
All IMVHOOC.
