(Near Ultraviolet to Thermal Infrared)

Archaeological Aerial Thermography and Near Infrared Photography
Here are some examples of my photography from the near ultraviolet to the thermal infrared.
I like handheld night photography for its spontaneity.
Low resolution thermal images emphasize form rather than detail.
(160x120 pixel sensor)
The depth of field provided by ultra wide angle lenses, combined with balanced direct and reflected light, can provide creatives opportunities as here looking into a shop window.
Some thermal cameras include a low resolution visible spectrum outline.
(thermal 160x120 pixels and visible 640x480 pixels)
Aerial photography can be carried out with a cheap action camera hanging from a kite line on a selfie stick. The two images below are from a Sony 12mp sensor.

When it comes to near infrared photography, I like a break from the colour of thermal infrared and prefer monochrome.
Here, I used a converted camera, but normal cameras usually have enough sensitivity to NIR as long as you use a tripod for the longer exposures involved. A 720nm filter will let through more IR light than higher values, whereas lower values let through more red light.
(visible versus near ultraviolet)
Here is an example of how things can look very different in the near ultraviolet.
Colour matching is only performed in the visible spectrum, so NUV can often detect differences in paint and structural materials.
