I remembered to bring my polarizer filter to Hawaii. I think it made a difference in capturing the ocean blues/greens. I went through my 600 shots and have saved 258 of them!! Tomorrow I will try to post something new and begin the process of viewing and commenting on all your work.
I went on a windjammer cruise and I can say a polarizer is a must for sun and ocean. (this was back in the day of film). Have loved you vacation pictures.
