Infrared - the world of invisible light
The wavelengths of the visible light spectrum, i.e. what we can see with the naked eye, range from 380 nm to around 740 nm, with ultraviolet light immediately before it and infrared light immediately after it, which we cannot see.
However, the fact that we cannot see this light with our eyes does not mean that it does not exist. With the HOYA R72 infrared filter, the photographer can see things through the infrared spectrum, which opens up completely new possibilities for playing with colors and leads to very interesting, sometimes amazing and definitely really creative results.
How the R72 infrared filter works
The R72 infrared filter does not allow any wavelengths before 740 nm to pass through, so that only light in the high-red range and in the infrared spectrum can enter the Lens. From 760 nm to 860 nm, the light transmission is 95%.
Since infrared light is exclusively in the red color spectrum, all areas in images appear in different shades of red. To achieve the black and white style typical of infrared photography, it is crucial to set the correct white balance before the image is converted to black and white in post-processing. A key difference is that the black and white contrast differs from the typical black and white settings in the camera or in post-processing when shooting without filters.
Advanced photographers go one step further and work with a color post-processing technique called "false color" to achieve very special results that are only possible with an infrared filter.
Shooting tips
Works well with digital cameras, especially mirrorless cameras or DSLRS without an IR cut filter in front of the sensor.
Due to the nature of infrared light, the filter factor and exposure compensation are very different from visible light, and the result depends largely on the lighting conditions.
Can be combined with colored black and white contrast filters such as the R1 Pro (red), Y2 Pro (yellow), YA3 Pro (orange) or other color filters to change color rendition or contrast effects.
