This represents a new venture into portraiture that I thought I would not like, but had to try. It turns out that it's a lot of fun and you can get some great shots at the same time.
The trick is getting the individual to allow you to use their image - after you've taken the shot. Sometimes they outright refuse but most people are flattered by your attentions, especially if the image makes them look good.
And you certainly meet some of the most interesting people imaginable.
