This actually “near infrared”. What it means is that I use a camera where the normal filter in front of all digital camera sensors has been modified or removed. The filter prevents not visible light or light at the edge of the visible range interfering with the camera’s interpretation of the image. With near infrared photography we replace that filter which only allows the longer wavelengths of light in the red end of the spectrum (>750nm> to get to the sensor.
The captured image is monochrome and looks pink on the camera review screen. Grass looks almost white, blue sky almost black. After some simple processing interesting images can be produced. All the following are infrared images. Some look like it and others look normal while the black and white versions show interesting detail.
What do you think?
