I've used ND filter in the past, for waterfalls. However, I don't have any ND filters presently and don't want to "buy and try" just anything. Based on the number of stops of light reduction balanced with price, I'm seriously considering this filter.
I am considering buying the B+W 77MM ND 0.9 8X FILTER so I can shoot portraiture with wider apertures under available light augmented with studio flash on location. I have a few questions for those using these filters in the field:
1. How does this filter perform for portraiture?
2. Are there any issues with color cast from the filter itself?
Thanks for any feedback you can give me.
