I only had a little time to play around with my camera last week when we were on vacation at the beach in Florida. I had taken my tripod down to the beach so we could take our own family portraits and decided to do some long exposure. Unfortunately I didn't have any of my polarizing or ND filters with me, so I was pretty limited.
I left my ISO at 100 and cranked down my aperture and was only able to get max of 1-2 second exposures, which mostly resulted in overexposed pictures.
Anyway it was just fun doing some experimenting and I think I got some interesting pictures.
