Thank you...yes, I use the "NDTimer" app on my iPhone to help with the calculation. I try not to guess too much, because I only get a couple of chances at getting it right when the exposure exceeds 10 minutes.
Thanks! Certainly...this picture was taken about 15 minutes after sunset. It's amazing how much color that the sensor can reveal (that my eyes can't see) after the sun has set. By the end of the exposure, it was so dark out there that I couldn't see the dials on my camera without a flashlight. I enjoy shooting before sunrise and after sunset because I like how the light becomes so soft.
Unfortunately, the Nikon 14-24 will not accept typical filters. It requires a special set up. I used the Fotodiox Wonderpana system with its 10 stop filter for this shot. So, the strength of the ND filter is the same as the Big Stopper.
I use the same approach for sunrises--often shooting about 30 minutes before the sun rises. Sometimes, I'll shoot both sunrise and sunset on the same day, and that becomes challenging in the summer months when the sun rises at 5:45 AM and sets at 9:15 PM!
Thanks Gary...I very much appreciate the feedback. I'm very much hoping that participating in these forums will get me thinking more about how to improve my pictures--and comments like your's help a great deal.
