I went back to South of France to see my family and friends, and I took a stroll to the beach to take pictures.
It was almost sunset but still bright. Cloudy sky, rocks and interesting waves, I gave a try to long exposure shots to capture the waves motion to get a smooth and blurry effect, and also, try to capture the colored sky.
The fact is, even with ISO 100, F22 or more, the photo was to bright. I gave a chance to a dark transparent plastic sheet that I have in my backpack (I sometime use it on my flash), but it wasn’t really great.
So I was wondering how seascape photographers are able to accomplish those kind of shot, and it comes to filters.
I was almost able to accomplish the expected effect on post-production with HDR image, but… it’s still not exactly what I wanted.
That’s why I was looking to learn more info about lens filters (UV filters, ND filters etc.) and decided to do some search about them.
I found interesting photography books at the library, and also some good videos on Youtube.
Here are my results, I hope that it will help you to get a better knowledge on the topic and get better photos if you are using them.
Books that I have quickly checked so far, and books are still a great way to learn techniques etc, in our digital era.
– How to Use Filters  Modern Photo Guide
– Pratique des Filtres  J. Lamouret / Edition Paul Montel
– Filtres Optiques et Numériques pour la Photo  Chris Weston / Dunod
A nice video from The Art Of Photography with Ted Forbes.

Update: I have ordered few filters on Amazon that I post here. They were cheaper than in store and work quite well.
Maybe more expensive ones are better under certain conditions, but so far they work well for me.
