    Is this a college assignment? Try printing to BW paper with a filter to boost contrast. It's a case of suck it & see.

    Of course, you could just scan them and convert to monochrome in memory...

    I once made a mono print from Fuji Reala. IIRC I used about a grade 3 paper. It needed more exposure than a mono neg but came out ok, in fact I still have it on the wall.

    It kind of depends on the subject - B&W paper isn't panchromatic - that's why safelights don't fog it! It responds a lot to blue, hardly at all to red, and not so much to green.

    Your colour neg is using complementary dyes (CMY) so blue things are (er I think) kind of yellowy-green, and green things like leaves are kind of blue... so the land in a landscapes might print well ut the sky probably won't.

    Best to experiment since that'll be a lot of fun !

    I think you need to use graded paper?

    I did this many years ago, it was fun, not at all difficult.

    If you're using VC papers, you may find you need to filter to a high value - 4-5 on the ilford scales. Otherwise use a high contrast paper to start with.

    Exposure values will be longer I found, but after that normal developing times seem to apply.

    Hope my two pennorth helps!
