Gorge panorama (b&w 720nm IR)

This is another slightly odd panorama, it's a 360° multi-row thing: 3 rows with 14 photos each, makes 42 in total.

It was already afternoon, mid October, so the light and season were way past the prime for infrared. Which, together with the dark 720nm filter and the shadowy location, meant me ending up with a shutter speed of 30 seconds.

Including a couple of test shots and including a 30 second in-camera long exposure noise reduction per image, the result was an active recording time of 45min!

And I had to constantly dance around the tripod on sloping wet rock covered with leaves, because the D90's only remote sensor is on its front side but I also had to get myself out of the frame too. A single bump into the tripod and the pano would have been ruined, one slip, me and the whole rig would have landed in the stream. It was quite an interesting experience to say the least.

 

So what you see here is a monochrome development of the initial trimmed mercator projection with a resolution of 21828 x 12226px (~266,9MP).

 

I feel like sharing some context and technical background (for all you infrared and panorama aficionados out there):

 

Here is a "crystal-ball"-like projection, where one can see what's missing to a full spherical panorama:

Here is a display of the stitching work, and the two main crops I decided to make that look nice:

Here is a snapshot of the fullspectrum D90 at work in front of the waterfall:
