Cloud lensing

DSC_7307

There are times when I’m flying and the clouds are just right to focus the suns light into a bright spot that follows the plane for several minutes. It is clearly some sort of reflection or refraction of the sun. What I like here is that you can see the sun, the sun’s reflection off the wing, the weird cloud effect *and* some lens flare so you can tell that the weird sun thing isn’t just in the lens. I could see it with the unaided eye … and now you can too.

Infrared blue

Two odd things about infrared cameras:

1) Even thought blue is well outside of the IR range, some things that are blue to the human eye get picked up as blue by the converted camera. I did some testing and I’m pretty sure that this is how this particular camera sees deep infrared. I have no idea why visible blue also reflects as deep IR, but it does.

2) Some lenses have hotspots, where the infrared light hits the sensor and bounces off to hit the rear of one of the elements of the lens (somewhere in front of the aperture) and bounces back to get detected again. In the final image, this shows up as a ghostly light, usually in the center of the frame. This effect usually just shows strongly up at certain aperture settings.

In this case, both effects worked to my advantage.

Minnehaha Falls in Infrared

After playing with one camera that had an infrared range that went into the visible (orange -> deep IR) and one that only did deep infrared, I thought I should convert one to a wider range of infrared, but one that was entirely invisible to the human eye.

This is what the Minnehaha Falls look like when you can’t look at them.

Wolf

Some zoos receive gifts of roadkill from their state’s DOT. This allows them to feed their animals at a lower cost while also giving the animals a wider variety of meat and stimulation. I was fortunate enough to see a wolf pack devour a deer this summer.

However, I know that many of you don’t want to be seeing that, so here is a photo of a wolf that needed a drink after eating a bit of deer.
