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.

This page at GeekTechnique discusses how most digital cameras are easily turned into infrared cameras by removing the IR blocking filter in front of the CCD, and replacing it with a filter that blocks visible light but passes IR. As luck would have it, exposed film negatives work very well as such a filter.

So I attempted this on my Kodak EasyShare CX6200, my first camera, which somehow still works after 6 years of abuse. It was surprisingly easy, minus the part where I had to manually resolder the coil which controls the shutter on the lens because it was attached by single hair-thin strands of uninsulated wire. But I digress...

I think it's working well. It very clearly passes IR light because the IR pens for the Wii whiteboard showed up quite brightly; it blocks light from LCD monitors and passes sunlight, but red LEDs seem to show up a bit. Trying it on another camera with more manual controls, and perhaps with a sharper filter, might prove interesting.
