II have shot late evening shots in the 3-10 minute range ( B+W film with reciprocity). But always wanted to shoot during the day, and get the same effect... thuis the ND filter. I know Ric said we should expect reciprocity failure from film and sensors.... I am not so sure about digital sensor reciprocity.....nor color shift ...... I think I need to do more research.....

The longest exposure I have taken so far is 4 minutes at night, this is with a 30MP medium format data back: http://richardmanphoto.com/PICS/20110410-CF006397-Edit.jpg This is 2 min exposure right at sunset (posted a couple times already but I just printed it out over 3 feet long and it's really sweet). Frank, this one uses the B&W 10 stopper. http://richardmanphoto.com/PICS/20121122-Scanned-20-2.jpg The best 10 stopper I read is the Lee, but you will need to get it at EBay as the wait time from Lee is ~3 months+!!!!
