Thanks, Peter - I'm glad you like the pictures.
Midges can be a problem. Where we were last week there was nearly always some breeze, and that keeps them away. But in warm, calm, moist conditions they can be a nightmare. There are various anti-midge sprays and ointments which work to a certain extent. My wife wears an anti-midge jacket, face-mask and hat - all one garment - made of very fine black net. This works totally against midges but has other downsides - hot, stuffy, etc. and not designed with photographers in mind!
