One of the most useful photographic location accessories is some form of rain and dust protection for the camera. The best solution I have found which cost nothing are the free shower caps that you get from hotels!
Firstly they are free, secondly the elasticated band holds it over the camera and lens when it’s windy, almost a perfect fit for all but the longest lens. I can get two shower caps compacted down into an old 35mm film canister and they have saved my gear on many occasions. If the camera is sitting on a tripod locked down for any period of time it’s great to cover it from the elements and not a big deal if you loose one or if they get trashed… plenty more hotel bathrooms to raid!
Here’s the camera sporting the shower cap solution last week…
… bearing in mind that the camera in the shot has been outside in gale force winds and rain for two days and the shower cap is looking about as battered as I was. (No…. I wasn’t wearing the other one!)
