Rain - possibly a daft question
I was at Bramham Horse Trials yesterday and it pretty much rained all day which is a shame since I've had some good pictures in the past. This is possibly a daft question but as you'll see in this picture (which I'm not putting up as a good one but it is a good example of the problem), my camera caught the rain and it looks like noise (especially on the tree in the background). Is there any way to avoid/lessen the effect either when shooting or in post processing.
