Awesome hi-res thermal panorama - pitch darkness
This is a hand-stitched panorama comprising eleven Therm-App thermal imager shots taken in pitch darkness in Night Vision mode at St Paul's Bay, Malta.
Elsewhere on my Photostream you can see a photo of the phone used to take these images, set up so that you can see just how dark it was. There was street lighting, but that did not cover the bay, the boats, the buildings or the sky. The clouds, for example, were completely invisible to the naked eye.
This just goes to show that what they say about thermal imaging - light is irrelevant - is absolutely true.
Image made with Therm-App themal imager, 19mm lens, Nexus 5 phone, small tripod. Actual overall image resolution estimated at 400x1500 pixels, which was upsampled a bit in the phone using the standard software. The stitching was done in an old copy of Paint Shop Pro, and I also did a bit of contrast enhancement using the Curves tool and applied a bit of sharpening for good measure. I didn't attempt to be subtle with the stitching. Correcting images, stitching, cloning and so on is part of my day job and I have the touch to do it well when I need to - and someone else is paying!
I deliberately left all the 'footer' bits in the image so you can see how it was put together, but it looked awful when I had all the Therm-App logos on the top so I'removed all but one of them.
Comments are warmly welcomed.
