I used to have a Nikon D80 and I could put it in remote mode and set the shutter speed to "bulb." I could use the ML-L3 IR remote to make any length exposure I wanted. I would press and hold the button on the remote, point the remote away from the camera, then do close the shutter I'd press the button again. I gave my D80 to my dad. I bought a D90. My dad upgraded the firmware on the D80. Now there is no "bulb" shutter speed when I put the cameras into remote mode. Longer than 30" just shows "--" and I get no response. What do I have to do to make really long exposures on these cameras without having to hold the button down on the camera? And why did Nikon remove this capability in the 1.11 firmware for the D80?
