Kolari IR 4×5.65″ Kit

Kolari IR 4x5.65" Kit contains:
-IR 590nm
-IR 665nm
-IR 720nm
-IR 850nm

Description:
-The 590nm infrared filter can produce vibrant false colors while allowing for flexibility in post-processing.
When to use this filter: Typically used to produce golden-yellow foliage and bright blue skies. This filter requires post-processing and is compatible with a full spectrum camera or a lower cutoff IR converted camera.
-665nm is the sweet spot between 590nm and 720nm, producing vibrant false colors with good black and white contrast.
When to use this filter: Typically used to produce light yellow leaves or the classic white IR look with blue skies. This filter requires post-processing and is compatible with a full spectrum or a lower cutoff IR converted camera.
-720nm is the tried-and-true classic IR filter. It allows for some great blue sky false color and provides great contrast and dynamic range for black and white. This is equivalent to the Hoya R72 and Wratten 89b.
When to use this filter: This filter is good if you are interested in shooting some mild color and black and white. This filter produces the traditional dark blue skies and can also be processed for color.

While not as high contrast as the 850nm, people prefer this filter over the 850nm for B&W work, as it allows a little more color for B&W processing. This filter requires post-processing and is compatible with a full spectrum camera or a lower cutoff IR converted camera. This filter can also be used with stock cameras with a long exposure.
-The 850nm filter is suitable for a dedicated black and white infrared camera. It will produce bright whites and pronounced darks. With a custom white balance in camera, the picture is close to pure B&W without any processing. Equivalent to the Wratten 87c.
When to use this filter: This filter is the best for the highest contrast B&W, resembling traditional B&W IR film. Also good for forensics and other applications where the deep IR wavelengths are helpful. This filter is compatible with a full spectrum camera or a lower cutoff IR converted camera. This filter can also be used with some stock cameras with a long exposure.
