I'll have to check, but if memory serves me correctly it was a 50mm prime at f/16 *EDIT* sadly it would seem this shot predates my current log book, witch meens my memory likely is serving me correctly, as I lost the old log book prior to accuiring any new lenses *end EDIT*It seems like its got a nice amount of noise and little bit of blur. What settings did you use? Did you use a heavy tripod or a light one and was there strong gusts of wind. It seems the trees in the foreground have been moving.
Also was this zoomed up?
What was your film?
And normal daylight film (such as ISO 100 or 200) ... someone will have to tell me how that behaves when it get's exposed for 2 and a half minutes!? Does long exposure cause grain also with slow film?
