In IR or infrared photography, the wavelength range of infrared light is used for image acquisition. This has wavelengths from 700 to 900 Nm (nanometers). For comparison: The human eye perceives light between a wavelength of 380 and 780 Nm.
With the help of an infrared filter, which blocks the visible part of the light and only allows light in the infrared range to pass through, current digital cameras can be used for infrared photography.
For me, I discovered this type of photography in 2019. The galleries shown here will therefore continue to grow.
