Ok, when I was in Photography many years ago, we were given a project. We had to take a picture at night of lights controling how long the shutter was open to get enough light exposure. I forget how long we did it, something like 10 sec or something (don't remember). To do this with my old Pentax I had a bulb attachment, that when squesed would trigger the shutter until released. My problem right now is I can't find my book for my Rebel 35mm, so I don't really know all of the features and buttons to get what i want. How can I set the shutter to stay open until I release the button? change the shutter speed etc? or maybe know where I can find this info. Thx for all of your help btw.
