Still more infrared panos

2 Comments

Here are some panos I’ve done with the IR-modified a7 and the 28mm f/1.4 Nikkor-D. I’m getting a little looser with my framing.

I ‘ve been playing with combining handheld HDR with stitching. AutoPano Giga will do the exposure blending and the stitching at the same time. It works well if there’s no wind. The picture below is what AutoPano did when presented with 13 three-exposure sets:

I also experimented yesterday morning with the Zeiss 15mm f/2.8 ZF.2. It’s quite a lens, and does well with IR.

  1. Hi Jim,

    I wasn’t sure of the best page to ask, as the question falls into a large Venn intersection of topics.

    I am in the process of choosing a main lens for stitched infrared images for a Fuji X-T2 which is being converted for 850nm.

    Assuming the candidate pool is free from hot spots, what are the key attributes for success?

    I was thinking that the narrow bandwidth would mean that it wouldn’t require broadband apochromaticism.

    I have been focusing on corner sharpness, but wondered if there were other important selection criteria?

    Also, what sort of total angles of vertical and horizontal fields of view are the median stitched oak images?

    Thanks so much.

      Correct.

      I think the main issue is finding a lens with no hot spots.

      Also, what sort of total angles of vertical and horizontal fields of view are the median stitched oak images?

      That’s an interesting question. I would guess around 90 degrees vertical and 120 horizontal, but that’s just a guess. I do remember at least one that seemed like it was nearly 180 degrees in both directions.
