Thanks everyone, I will check out the link you guys recommended.
I'm going to purchase some GND filters for landscaping lesson in about 2 weeks. B&H (
http://www.bhphotovideo.com/) is the north american based online shop that carries lots of filter brands. Could anyone give me some suggestions on choosing the brand since I don't want to replace them when I get a little advanced.
Right now my purchasing list is:
1. kokin filter holder P (+ 77mm ring adapter)
2. 1 GND 2-stop soft edge
3. 1 GND 3-stop hard edge
4. 1 bag holding the filters
For the filters, the brands are: Lee, B+W, Cokin, Hitech, Singh-Ray, Schneider, Tiffen, Hoya
There are just too many of them and I really have no experience of what is good and bad. Any suggestions?
Thank you all in advance!
