It is difficult to imagine that in a day when all photographers are pushing the manufacturers for higher and higher ISO that at the same time there is a need for lower and lower ISO. The truth is I enjoy shooting 30 sec and longer exposures during the daylight hours. There is no way to reduce the ISO low enough to create such long exposures while the sun is up.
The only way to create this long shutter speed is with the use of neutral density filters. If you’re like me and want to attempt this very cool look, I recommend the new Lee ND filter called “The Big Stopper”. This filter requires their holder but offers 10 stops of density to help you create those long exposures.
Life is short, take pictures!
