el ensayo (510nm IR mono)

This thing was more of a rushed experiment one could say, due to popular demand and opportunity.

Since the hotspot issue resolved itself with the fullspec D3300, I find myself doing a lot of single row panoramas with the Tamron, which now appears more versatile than ever. Not just the focal range (24mm-13mm), but also ease of focus (different wavelength and focal length) and cooperation with the pano head. 13mm is wide!, but being the greedy bastard I am, I caught myself wanting even more on occasion, so I started to experiment with the 10mm end (I used to refrain from due the distortion) and how it might perform doing panoramas with.

 

So I was taking pictures in the opposite direction, as I noticed that this mega cloud attempted to reach for the sun, literally (and it did eventually!). I turned around, could not fit it all in and said, f*** it, I'm going 10mm and tilt it up as well, straight into the blazing sun, not giving a hoot.

As you can see at the many 'pearl strings' (ghosting), the overlap was huge, on purpose, way more than necessary so I can work it on the computer. I only had time to do 510nm, so I performed my 'digital Aerochrome' development, it was ok, but well.., so I played around with b&w conversions (for the record: I did brighten up the red, magenta, purple, to fake a light Wood Effect that's not really there at that wavelength, the image would not have worked other-wise) and I happen to like this gritty dark version. Why not?

 

Conclusion: 10mm kinda works, panoramically, the center is not too bad (even with half the images taken / used), the rim has some fuzz going but not a deal-breaker without too much crop. Still amazed how controlled the flare is, ..like what? And it was pretty in the color version (same as the foliage mostly) and I could beautify it due to the huge overlap.

It's not bad at all, yet the full extent, how freakin' high this pano reaches into the sky is a bit lost nonetheless I feel. Will I do this setup (10mm) again if it's indicated? Yes, I think so. Would have been interesting to be able to compare it to a 24mm 3 row layout in this situation though.
