Dear Friends,

I have just finished some C-41 developing and noticed several areas in the background of the image that picked up stray light patches from the flash - and these are now dark areas on the negative. As the backdrop was black, I would like to eliminate these before I print. Is there a procedure for bleaching these out of Portra 160VC? These are 4 x 5 negatives, I hasten to add - there is room to retouch.
