Ultraviolet and Infrared Photography - Ferns in partial shade
Ferns in Georgia are quite plentiful, with the dense canopy that the century old trees provide these little plants grow on the forest floor. They are simple flora, and do not produce flowers instead producing spores for reproduction. Their Latin name cryptogram is because of the spores on the underside of the the leaves hidden from view hence crypto-gram.

A mature Autumn fern growing spores on the underside of the the leaves. Since ferns do not produce flowers, they produce spores.
Young Autumn ferns growing out towards the light.
Light is filtered and giving a pattern like appearance on the fern fronds.
A Cinnamon fern, these things grow real big. Almost five feet tall in the right environments. For a fern thats pretty impressive, besides tree ferns which do not grow in the area.
Autumn ferns all growing around each other, making a dense ground canopy of leaves.
Out in the sunlight, their colors are more of a bright white.
Young ferns, only a year or two old. Growing among the mondo grass.

I take pictures with a special camera. Its a Mirrorless DSLR that has been modified by Life Pixel to see light in other wavelengths. This allows my camera to see light in the Infrared [IR] around 1300 NM wavelength, through the visual spectrum and into the Ultraviolet A and B wavelengths roughly into the 300 NM wavelength.
I carry many filters on me to make the photos you see in my blog, these filters screw on my lens and help me isolate certain wavelengths for certain scenes. These filters can be IR / UV pass-through filters to assist me get a natural photo taking out the UV and IR light. Or I may use a Infrared pass-through filter capture just IR light. I can do the same with UV light as well, though I need some better filters which they can cost a few hundred dollars for true Ultraviolet pass through filters. So for right now I have B + W 403 bandpass filters that still allow some IR light in, due to their cheaper material.
There are also exotic glasses made of sapphire and germanium I am open to working with to replace my silica glass hot mirror with a material that allows even longer wavelengths of infrared to enter my cameras sensor. Special sensors, lenses and filters of that material would be needed as well, so it would be a big project but one that may give some even more unique photography results.
