Built in light meters are calibrated to meter reflective light. So when light sources are in the image frame you normally get useless readouts. In my understanding auroras are actually light sources. In my experience the LX light meter works remarkably well when light sources are in the image frame. I don't exactly know why this is. But I have recently made some night cityscape slides with exposure times up to 18 minutes. They came out astonishingly fine (but you will need CC filters to compensate the color shift at such long exposure times). Alexander __________________________________ Do you Yahoo!? Yahoo!
