I was working on the bicentennial image last weekend and came a cross yet another use for the High Pass filter.  Have you ever layered an image on top of another, changed the blending mode to say Hard Light, and watched all of your contrast and detail from the image below disappear?  Try making a High Pass from the layer below and place it on top of the middle layer, thus creating a High Pass Sandwich.  Check it out:

Check out the before and after.  Look closely, the details are popped out slightly, not blaring, but just enough to make the underlying layer more prominent.  These very minute details are extremely important when compositing images.  You can always tone down the effect by bringing the Opacity and Fill down on the High Passed layer.

Most people think I am passionate about Photography, but in reality I am not.

WHAT!?!

Wait, before you freak out, you are on a photo site, I am addicted to post processing. To be more specific, I am addicted to workflow efficiency and cracking the codes to complex systems. That's what I do here, crack the code to photo post processing and present it in a concise way, for you :)
