This may be an easy question but i have just received my t2i about a month ago and have been posting here recently about night photography etc.
First question is since i do not have magic lantern how long would i have to leave my shutter open on bulb to get a full circular star trail.
And secondly leaving my shutter open for about 15 to 30 sec will make my picture super bright during the daytime. Obviously because i am letting so much light in during a time hour...but i have seen pics of water falls or a pinwheel streak...or a game of pool with the ball streaks all during the day time. Basically i am asking how to leave my shutter open and get these kind of pics during the day time.
