Hi Diane... These are incredible!!!! I was just able to borrow a filter from a friend. I am going to try some tomorrow, but I have some questions. 1. Is the filter you have opaque to your eye??? 2. What are you setting your exposures to (i.e. ISO rating, time and f-stop)??? 3. Did you white balance for these??? 4. Can I come and swim in your pool??? It has been really hot here :)
