Longer exposure times over 30 seconds?

12 years 10 months ago #103856 by Hawkins
I was just wondering last night when I was playing around with longer exposure times, how can I maintain a exposure that is longer than let's say 30 seconds with out using a stand alone meter as the camera's built in meter is nearly useless at these times?? A gal friend of mine was telling me there are some equations that will help with this?

Anyone have some thoughts to share?
