I have a 4x5" negative with a small, but deep scratch on the emulsion side of the negative. It is in the sky portion, in which the sky will probably print as a light grey or maybe even close to white. However the defect on the emulsion will show up as a distracting black.

My ideas for salvaging a nice 11x14" print are as follows:

1) Retouch the negative. I've tried this, and it was a disaster! How on earth do you do it? I have Spotone and #000 brushes

2) Somehow locally diffuse or blur the area? Any ideas here?
