Ice Bloom on Acros 100

Back on December 5th I processed a batch of Acros 100 film.  These were large format 4" x 5" negatives, processed in Rodinal developer.  I previously posted some scans from the north rim of the Grand Canyon that were part of this batch.  These three more recent negatives were all exposed back in November, when the ice bloom was underway on the North Saskatchewan River.  That ice is moving deceptively quickly and you either have to use a relatively fast shutter speed to stop it, or a long one that allows it to blur out and become streaks.  I tried both methods during this outing.  This was the day that little Helena came along with me, and was running around like crazy despite having recently split open her knee for ten stitches...
