More info

BLW files are mostly used to convert digital photos into a black and white image. With the help of the settings, different presets (blw files) can be used to create completely different black and white images.

The window for the black / white function can be opened via 'Picture-> Adjustments-> Black-white'. Here you can load and save the settings. Photoshop already comes with some presets, including blue filter, maximum black or infrared, but without BLW files.
