Post Gaussian Blur and the High-Pass Filter - What gives?

As we say in Brazil - they're just the two sides of the same coin.
(PS 7.0 - but applies everywhere) [details]

I guess Brazil has at least one good teacher. Thanks for the lesson. I'm waiting for the next ones.

Positively facinating

Pixel math unleashed. This begs for an action for the layer setup!

Like Ed, I'm looking forward to future installments. Fine work, sir.

Great tutorial Ro, not sure just how much use it will be, but it sure gives you an insight into how these filters work. Looking forward to the next, where my reservations will no doubt be answered.

Sure thing, Gary.
Like I said in the tutorial, this was just the groundwork, the good stuff starts in the next one.

Sorry about that, I haven't yet mastered the fine art of tutorial formatting.
This is the one: Skin tone correction - Unclipping

"Photoshop does not have a direct blending option for subtraction"

Linear Dodge, but it's 'upside-down'.
Just invert.

Linear Burn = Addition

Linear Light = LD/LB
(although, I've noticed some funkiness at the extremes)

I am, of course, open to corrections.

Excellant article on High Pass for some more nitty-gritty:
