I take quite a lot of...

...candid photos and I particularly like to capture shots of people deep in thought, or busy doing something, because it makes pictures more interesting. Also, they are less likely to spot the camera so they behave normally.

Both my shots for my blip subject and today's  extra went unnoticed by the subjects.

I did take another possible shot,  but the lady I snapped spotted the camera. She immediately started to talk to me about cameras and her own photography. 

After our conversation, I decided not to use her photo.
