I've had a Canon SL1 for about a month now and I'm obsessed with it. As will become very clear, I am a total newbie with this type of camera and understand very little, but this hasn't stopped me playing around, mostly in the automatic setting. I am sure it's easy and I'm being a little dumb, but how do I set my camera up for long exposures? I am going to Joshua tree this weekend and really want to play around with some night long exposures. I have no idea what setting to use and how to set a time period. Any help with this and simple clear dumb person proof steps would be very much appreciated.
