Re: [Digital BW] slightly OT: developing expired B&W film

2003-05-06 by Mark Savoia

It will get a base fog over time. If the film has been refrigerated, it 
will be much less. The film will also loose some speed so a lower ISO 
and possibly a little over development may be in order also. Test a roll 
first.
