I saw a previous thread regarding these but I have mose specific questions so thought I'd start a new thread (hope that's okay?).
I am looking to use them for daytime street shots (people and cars etc) so that I can slow down the shutter speed to creae a ghost-like effect while not overexposing the background/buildings etc.
I own a Canon 50mm 1.8 and a Canon 10-22mm and was looking at getting an ND filter for each. Someone here mentioned the Cokin filters so that you didnt have to buy 2 seperate filters to fit each thread size for both lenses. However on their website (http://www.cokin.co.uk/pages/filters.htm
) they only seem to have 'graduated' filters. Does this mean that if I were to take photos of people then only their top half would be ghost-like and the bottom half would be overexposed? Do I need an ND filter that is not graduated?
I can see myself wanting a graduated filter for some nice landscape shots where there is a bright skiy and clouds so the graduated filters would also be useful at some point, but for people, I'm a bit confused.
Any suggestions/tips/product links would be a great help!
