Hello all. I just purchased a 3.0 nd filter by b+w. I did all research and everything. I printed out all the metering and exposure graphs and none of them are adding up when I go to use it. What is the best mode to shoot in while using this filter. I have used the techniques posted here to the T and cannot figure it out. Seems like Bulb mode is the best way to go, but I don't know. I would like to know how it works for the charts as well. Thanks!
