Iwan, Just thinking out loud here: Where you using a remote release (as you should for long time exposures ;-)? and when you changed the subject, was there any light shining behind you? Light falling into the viewfinder will affect the TTL readings and that might explain the situation: while composing, your eye on the viewfinder blocks any light and the reading is 30'' f/2.8. Then you back up, light comes into the viewfinder, affecting your exposure reading and you press the remote release, resulting on a underexposed image. When working with a remote release I use mainly (M)anual mode to avoid this problem. -greetz, Gerard. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
