The UFOs up there must be, and are coming down here to near ground level. I know NASA do a very good job at revealing this aerial phenomena using UV cameras and we know now IR imaging (NIR) works in this capacity as well. I'm unable to say what these things are or where they are from, but they do exist. Research shows there are strange objects buzzing around our skies that use a cloaking system that gives light the ability to bend around themselves which renders them invisible. I am also going to start at the beginning of my investigations and slowly proceed through to the present. Anything potentially normal like a balloon or similar will not be posted unless stated otherwise. On this blog I will only try and post what I think are my significant captures, objects that wouldn't have been recorded if it wasn't for the use of infrared filming. This worsens the larger the sensor becomes, but becomes less apparent the smaller the sensor is. This is because the point of focus in the visible light wavelengths (400nm-700nm) differs from near IR (400nm-1200nm) and it confuses the camera so it sits between the two, producing no perfect focus at all.

With full spectrum or infrared DSLR cameras, the focus has to be re-calibrated to focus on the desired light wavelength. My main concern was obviously just completely wrecking the camera and second, will there be any focusing issues. After doing a whole ton of research and emailing around for quotes, most being around the £250 mark, I decided to do it myself. Getting to know this camera for a was great fun, way different to any video camera that I have previously owned, but I had to think about how I was going to turn it into a full spectrum or infrared camera, I knew before buying it that I would get around to modifying it. After watching countless P900 zoom videos on YouTube and reading no end of rave reviews, I decided to buy one and try it out for myself. In 2015 Nikon released it's new flagship bridge camera, the Coolpix P900 which boasted a whopping 83x optical zoom, it also has a 3" pull out swivel LCD, a highly rated viewfinder and can film in 1080p50FPS. Also, a camcorder producing 0x to 15x zoom also requires moving parts, the higher the optical zoom, the more the focal length has to be increased and that is a lot to get into a consumer camcorder. In short, the optics have to stay relative to the sensor size, if not images become more cropped the larger the sensor becomes.
As most camcorders now are HD (1920x1080p) and even 4K (3840x2160) actual sensor size is also growing within these camcorders and this is having a negative impact on optical zoom. As with most things, camcorders evolve, the largest improvement being image resolution. At one point, most had 40x optical zoom and a simple but functional viewfinder, a must when filming the sky. For many years Sony handycams were a wise choice as they did tick all the boxes, a simple IR pass filter that screwed to the lens, a quick flick to 'nightshot' and off you went.
Over this last few years I have had real trouble trying to find a video camera that ticks all the right boxes, an impressive optical zoom, a decent viewfinder and for me it has to have infrared capabilities.
