Can anyone send me in the right direction for a tutorial/instructions on how to take a picture while standing on a bridge over the highway and take a long exposure of the cars at night to get their lights streaking. Did it years ago with a full manual Nikon with tripod and a shutter cord. Don't remember my other settings... I'm guessing with the D50 it will all be different anyway.. Do I need the remote and or can I just change the ISO, etc etc...
