Film was not faster than 320 ASA in these days >> at least not quality enough for me to use ...
Now I'm curious when this photo was taken. My remarks were based on an assumption that it was a relatively recent photo taken with a relatively recent DSLR. My bad.
Back in the 70's, I had a Mamiya C33 TLR, and I would have never been able to capture an image like this.
SO this shot :: a 60mm 4.0 lens ( 35mm ) this lens was stopped down to 5.6 @ maybe 15th > and it was a candid > I had no idea he was going to ride into this spot of the forest >> grab the camera and hope for the best. I focused on the rider .. no way to freeze a oncoming horse > at that angle & speed ..
Wow, you are a lot more organized than I ever was ... to have kept reconds on exposure settings that you still have years later.
I do find myself wishing the EXIF info on submitted photos was readily available. Perhaps I don't know how to locate the EXIF?
I think my reaction to the photo, and then comments, would have been rather different if I'd been aware that the image was captured with film.
