You don't give details about the process used to generate the image or how you digitized the negative, but I've been able to pull much better color and image quality from an FP-100C negative. It has been quite a few years since I've messed around with this material because the results obtained were not to my liking. Don't get me wrong...prints from these negs have a certain look, for sure, just not to my taste. Therefore, I stopped playing around with this material.
Your example looks like the pack was not pulled evenly and smoothly to begin development and, maybe, it wasn't cleared properly of all the goo. If you still have some of this film, I do a bit of research on various techniques for recovering the negative and keep working at it.
Good luck!
