Digital BW, The Print

Thanks for the tip but I guess you are doing something with channel mixer
rather than split channels and then altering the opacity (0-100% values
only) of each layer.

Try pushing red past 100%, setting green to zero, and making blue negative
by the same amount (e.g., 130% and -30%). That's something you can't even
approximate with filters.
