Digital BW, The Print

Hi Todd,

Well, I don't care for halos at all, and try to do everything I can to
eliminate the obvious ones, such as you'd find between a rock and a sky,
or a building and a sky. They're ok in weathered wood or grass, if they
are barely perceptible.  Or are you speaking of incredible tiny ones? 

Anyway, this sharpen filter, similar but a little better than Katrin
Eisemann's sharpen filter in her Retouching book. (both are great, as is
Johnny Deadman's).

On the image of my cat, there is no halo on a 13x19 inch print that i
can see. This filter removes most of the halo effect.

In film, it used to be called a Mackie line. Never did like it, except
in a solarized print, where it just "fit in."
