550 nm Infrared Filter

Description

Note:

This filter is only suitable for infrared-modified cameras. The effects shown cannot be achieved with a normal, unmodified camera.

The camera must be converted with one of the following filters: 280 nm (full spectrum).

The weakest infrared filter is a 550 nm long-pass filter, which allows the spectrum from 550 nm to the deep IR of 1,200 nm to pass through. This orange piece of glass is of little interest for black and white infrared photography, but offers the possibility of generating an image with a blue sky and red foliage. This comes very close to the analog infrared film "Kodak Aerochrome" and is an image effect that many infrared photographers strive for. Post-processing is somewhat more complex because a double channel swap has to be carried out (red-blue and green-blue). With the channel mixer and a little experimentation, many other image effects are possible. As the weakest infrared filter, it can also be combined with many other filters.
