I would like to take long exposure shots in the day, but I just can't imagine how to do it because even fireworks (night shot) exposed for more than five seconds are too bright.
I did some research, and I guess it's because I have no filter. What do you recommend to me for night and for day for long exposure shots?
Answer
You're looking for ND (as in Neutral Density) filter. They're usually marked as ND2, ND4, ND8, ..., each step indicating 1-stop change in your exposure settings. For example if you were shooting at f/2,8, 1/100, ISO100 then adding ND2 filter will give you options to shoot either at f/2,0, 1/100, ISO100 or f/2,8, 1/50, ISO100.
Most of recognized filter manufacturers have ND filters in their lineup, including Hoya, B+W, Singh Ray, Lee, Cokin.
Should you already own a polarizing filter you might use it to get rid of 1-2 steps of light or even combine it with the second polarizer to create a variable density ND filter.
