One of the things I really wanted to see were the sunset's. I didn't know I would also be up to see the sunrise's. I thought it would be pretty neat to see a whole open sky and get shot's of it. I live in the suburbs, all I see are houses and trees. I wanted to see all the pretty colors that are associated with sunset's. But as I discovered, to get a real pretty sunset, you need pollution. Hawaii is nice, as they have volcanic ash in the air. As ocean were clean (above the ocean anyway), the sunset's were orange and yellow.
I have many shots, most taken with a Cokin Resin .6 graduated neutral density filter. I found this filter worked well for sunset's and the like, mostly because it takes so long to put on. I could only do it in my room. With the filter, I was able to expose the sky properly, without losing too much information on the ground. For the record, these pictures are my first real attempts in sunset photography.
