When weather physically impacts your photos

On my blog today I'm featuring Jan Geisen's Stormy Pinholes photos. He got some interesting results by photographing in the middle of some huge storms, which leaked rainwater into his pinhole cameras. http://fslashd.com/2015/05/jan-geisen-stormy-pinholes/

I think the impact of the rainwater directly on the paper negatives added to the aesthetic of the photos. How do you folks feel about it?
