No thanks. Just the thought of it makes me cringe.Opal search in Australia, the mine was 30 m (100 ft) deep. We crawled through 60 cm (2 ft) wide tunnels with a pickaxe and cheap 9 volt headlamps.
I still shudder when I think back on it.
I had forgotten about the beginning photography class I took at a community college decades ago. Trying to load the film into the film reel correctly without getting fingerprints all over the film, without being able to see anything, could be frustrating.Mammoth Cave and a film loading closet in the darkroom at school.
