Here are two shots, taken from the same spot at Radipole Lake. I was experimenting with two techniques, the first is long exposures using a ND8 Filter and the second is creating a small panorama.

This shot was the first time i used my ND8 Filter. For some reason these shots came out very grainy. I was shooting on an iso of 400, so wasn't expecting them to be particularly grainy, so i am unsure if the filter could cause it, as it was a cheap one from ebay.
