thanks for your reply, but I already tried manual splitgrade, even in coincidence with pre-flash - the print still went wrong, itīs not enough..

I just didnīt want to mention how desperate I am with these negatives... splitgrade is always my last resort. ,-)

I donīt know what was on my mind then - unknown lens, new film, untested procedures and an excursion to London... young and stupid. <g>
