lordy, andy- you've invented the new
streaking for 70mm. copyright it before
everyone knows how you've done it.
ever pre-wet film before the fast
working developer is applied? you
concealed the overall developing time.
ever hear of nitrogen burst? all of these
factors relate to each other.you didn't
say diameter of 70mm reel or total
developing time.    simon nathan

  Thanks!!!

I would try more gentle inversions or a slightly different style. Keep it
at 3 but maybe slow down. Jamie
