[QUOTE="Scott Murray, post: 237024, member: 9753"] [COLOR=#333333][FONT=Helvetica]Here is a list of settings you would need to use at several common apertures to get a 30 second exposure: [/FONT][/COLOR] [COLOR=#333333][FONT=Helvetica]f/1.4 and ISO400 = 30s f/2.8 and ISO1600 = 30s f/4.0 and ISO3200 = 30s f/5.6 and ISO6400 = 30s [/FONT][/COLOR] [COLOR=#333333][FONT=Helvetica]It goes without saying (but I’m going to say it anyways) you really want to try to get your hands on the fastest lens you can (largest aperture, smallest “F” number). These are just a good base to start with, once you frame your shot and take a few test shots, you will probably need to play around with the ISO to get the proper exposure.
