Cheers. I went out on Friday night to give it a try...but:
- Before I went out, I gave things a try - Idiot....the mirror is always reset by the winding action, not the photo taking, so when the bulb is released all you get is the click....face palm...
- It was too windy when I got to my location (about 50 metres walk)...so there was no point.
As mentioned elsewhere, I have plans to make an electronic remote release....but I have spent a bit too much over the last month or so.
Cheers for everyones advice!
