if its a wireless remote try a new battery may be enough for short transmission but when run down causes issues
So, a few weeks ago, i tried one of my first long exposures, in the bulb mode (nikon D90). I used a cheap remote (£2 on offer, hehe), and everything worked fine. One click on the remote to start it, and one to end it.
However, after some time, i had to actually hold the button down, or it would just take a picture of an exposure of 1/2 or something.
After some MORE time, it doesn't even work anymore. When i set the shutter release on "w/ remote", and twist the exposure all the way after 30" (sometimes only lets me 10", no idea why), and after that, instead of giving me BULB, it simply shows " -- ". when i change the shutter release on single (by pressing the button), it does let me use BULB. when back on remote, it doesn't.
Any ideas as to why this is happening?
I presume you are dialling in your exposure time on the remote - I have only used the manual ones where I have to depress and lock in for bulb mode
