Do I need just the eh-5a (EH-5A AC Adapter from Nikon) or do I also need the EP-5 ? (EP-5 Power Supply Connector from Nikon ) It seems like you need both, but it's a little unclear on the nikon website.
Here's what I tried out yesterday: http://nikonites.com/general-photography-forum/1082-timelapse-sunset-created-lightroom.htmlThat would be interesting. What specifically are you going to shoot all night? I would like to see some of those shots when you get them done. Very curious.
