Went to a homecoming parade for the High School the other day, took this shot...will post some parade pics when I get a chance. Then the second shot was from the park yesterday, I used my IR filter on it and converted in PS.
Lafoto...for IR shots it depends on the camera and filter, the Hoya R72 on a DRebel XT takes longer, but the times could be different using another camera with film...I typically start out with 30 secs and go up from there, the longest one I've done was about 2 mins...
