Daniel, I'm sure you'll be receiving explicit answers to your question, but let me offer this in the meantime. I don't have access to that particular camera and I'm only guessing, but check the mode selector for a "B". This is the retro symbol for "timed exposure" when the air "bulb" was the commonly used remote shutter release. Still available if you shop a bit. You are, of course, right to acquire a substantial tripod and a remote shutter release. The water fall ribbon effect may not require the exposure time are perhaps assuming. I've used 100ISO film (and slower) almost exclusively, which lends itself to such work. I have stacked 2 polarizing filters a couple times and used an AE camera setting. Work with the polarizing angle of each filter until the scene is substantially darkened. Check meter for its reaction and if the meter has no objection, bracket a few frames and plan on some interesting images. Enjoy! Jack __________________________________________________ Do You Yahoo!?
