If you do flowers or palm fronds like I did for a hotel, you get an artsy, painterly texture. Quite nice really. Just got new FPG catalogue in mail yesterday and it has one of the images from that set in it. Maybe it will sell. The more movement in the camera or object the more fluid the image. But absolutely need a motordrive. God with the F3 motor at 32 frames sequential you have to clear it with the noise abatement commitees. donal - -- Donal Philby San Diego http://www.donalphilby.com
