Its been a warm, wet and mostly overcast day. Normally I don´t use my external flash for insect photography but with not enough natural light to get decent shutter speeds I decided to add a little light to take this shot.
@hjv thank you Hubregt, you just have to ask them nicely and have a bucketload of patience. It also depends on the species of damselfly, some are easily scared off others are just curious what you are doing
