And distance calculating flash involves setting the latitude of the film or digital sensor. I mean you hope that the top of the range is complete white. In my experience bouncing light, colour of objects, colour of room, etc etc all influence the amount of light that gets to your subject. Of course digital has made this all much easier, since we can do a test and know it's working the way we want in each lighting condition. That ever elusive point and shoot for perfect flash still isn't possible. But ETTL comes close. I like the way I can turn off auto flash reduction on my 10D, that's a good feature. Now, I can dial in my flash compensation based on the lighting ratios that I know work, without something else changing it automatically. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
