I have found you need to be between a -10 to -15 ND filter for mid day long exposures. I sometime will stack my polarizing filter to extend the exposure time.

excellent work John! directly put into my favs ++

seems as if a simple ND8 is not enough,,,, definitely not enough ;-)

cheers from Bernd

Ken,
These two photographs were taken during mid day. The crossing was taken just before a storm blew in. It is actual the full moon rising behind the storm. This was my first attempt at long exposure with a digital camera. I have made many long exposures using film and knew the reciprocity factor I needed to apply to my exposure calculation for film. Example: A 2 minute meter reading with Tmax film required a 5 minute exposure to record the image properly. I mistakenly overexposed the image of The Crossing thinking I would need to adjust for reciprocity failure. I actually had a meter calculation of around 2 1/2 minutes but gave to exposure 5 minutes. The image was overexposed and I later had to deal with that in PS. The important thing to remember with long exposures, is that my mistake was only equivalent to one f-stp of light over exposed. The RAW image looked bad but it was still in the ballpark. The best way to make successful long exposures is to have consistent work habits. I always use a tripod, lock up the mirror, use a cable release, turn off image stabilizer, ect. I meter in manual mode and set my f-stop to the smallest aperture. Always use the lowest ISO setting on your camera when you can (mine is ISO 50). Once I meter the scene with my camera and then calculate down the -10 to -13 stops of to determine the correct exposure. Then I set the camera to Bulb mode for long exposure. I use a cheat sheet with a few different exposure time calculations on it and carry it with me. I hope this helps. John

I really like this technique and would be interested in hearing more about how to get these results. I assume you are shooting at sunrise with the -13 ND filter and just set a long shutter exposure, but how do you determine how long? The image of the bridge in Bahia Honda Key was at 3 minutes and this one at 5 minutes.
