I am seldom bothered by mosquitoes. I never use bug dope (DEET or otherwise), and I hardly react to their bites (and I have fed millions of mosquitoes). I don't like them inside my LF camera or sitting on my sheet film. To be honest with you, I don't even remember if there were mosquitoes around while I took that picture, though I know there were mosquitoes on that trip.
Thanks for the link to your photo. I always find it interesting to see another photo simular to one I have taken - knowing that they are 100% independant creations.
