You should bleach (c-41 bleach will work), and then develop in c-41- don't push process- to get a high contrast, little more grainy color negative. You can redevelop it in B&W developer-after the bleach of course- but you will get a dull B&W negative anyways. If you have used a wetting agent then you have to rinse in heavily for 20 min.(posted 8512 days ago)
