A few months ago there was a post on this forum with a link to a procedure for producing smooth bandpass masks (high mid tones, mid mid tone, low mid tones, etc).  I thought I had bookmarked it but apparently not.  Nor have I found the magic search terms to turn it up here.  Ring any bells to anyone?

Tony sells his. They are OK, but nothing special.

Here's how to make your own (write an action):

There is also a link to my actions on that page, which you can download for free, which includes luminosity masks

Thanks.  Tony's was the link I was thinking of.
