Chris Hodapp 94310f0f9d Migrate *all* photos to the cavelab setup. Header/footer still broken.
Completely remove the other image gallery themes.

I now have: image galleries, with lightboxes, and captions, with links
in them (and to Hugo pages), with full images lazy-loaded, with all
thumbnails auto-generated, and the ability to do this on both
individual images *and* with globbing, from page resources, from this
page or any specified one.  See cavelab_notes.txt.

It also has the ability to use Exif data of the photo - if I
preprocess it into a JSON file.

Known issues:
- The theme header/footer are now being overridden.  I am working to
  fix this first.
- I am missing some kind of fonts/images needed for the lightbox to
  show up properly.

Lack of some amount of sunshine is rarely a problem here, it seems. I did this next cyanotype outdoors in very overcast light while it was snowing lightly. The snow was minor since a sheet of glass covered everything, and overcast light possibly was perfect because of how even and omnidirectional it was. The contrast that I achieved in this print surprised me; the dark areas just turned out so much darker than the last print.

I still had sensitizer left, so I decided to try some prints on fabric as well. These I exposed for almost 2 hours, maybe longer, under a 200 watt bulb. They didn't turn out as even as I'd like, but I was rushing things a bit and some spots of the towel weren't fully dry when I started exposing. However, I'm still impressed with how it turned out.

Rob next door to the Hive loaned me a halftone negative he had (since I had nothing else on hand in the way of transparencies) and I made a few exposures of this, but had some problems with the highlights. I really should find some negatives that aren't monochrome (as this was, being a halftone image) so I can figure out how to get the tones right.
