Thanks.
Originally, I was trying to avoid having the shutter open when the lighthouse light was pointed my way, but that didn't work out. ; I was afraid that the light would trick the exposure meter into taking too short of an exposure. ; So I triggered the shutter just after the lighthouse light passed me.
This was taken with the 7D, Av mode, RAW, ; f/8, 15s, ISO 100, at 28mm, tripod. ; Slightly adjusted in Aperture 3.
Regards,
Boris
PS--One of the things I don't like about SmugMug is that you don't get EXIF data in the linked photos. ; If you go to SmugMug and click on the photo, I think you can get the data, but it's not as simple as I'd like.
