Nikon D90 remote shooting?
I have a remote that I use on my friends Nikon D90, but I have no idea how to sync with work. Generally use a D60, so I do not have the manual for the D90. Any help would be awesome, thank you very much! Please be specific if possible:)
on the menu you will find 4 different types of shooting mode (single, continuous, remote control, remote control 2 seconds). choose "remote" or "2 distance "s there.
