Oddly, I have a situation that is the diametrically opposite of yours: in 1995 I went on solo bicycle trip across vast areas of China in 3 months. I carried two Nikon FM-2 bodies, one was always loaded with slide film, the other with b/w. I also did lots of sound recordings there. While I created a carefully curated slide show for private audiences, all I did with the dozens of b/w rolls was to develop & archive them. I didn't even produce contact sheets of them for a cursory examination. I just have that hidden treasure. I can't explain.
