The Devil is in the Details: The Hi-Lo Pass Sharpening Filter for Photoshop

As you can see, the Devil is literally in the details:


What is it?
The Hi-Lo Pass Sharpening Photoshop Action is ideal for enhancing images cloaked demons, in that it provides a granular access to every detail they contain (by merit of frequency separation) by separating the elements you want to keep as is (in the case of demonic imaging, color) from those you want to change (also in the case of demonic imaging, texture).

Is it hard to understand?
The technique is pretty basic, and follows the same pattern as nearly every other filter that uses frequency separation to achieve its end. The image is divided into two parts: a high-pass frequency map, which represented by image data is completely gray save a few faint lines made by the objects with sharp-contrasting edges) and a low-pass frequency map, a blurry version of the original image. When separated in this way, changes can be made to certain elements of the image without effecting other elements (such as color and texture, as already mentioned).

How do conventional image filters apply to images made of demons?
While that, of course, is a benefit shared with regular images, frequency separation has a special applicability to images made of invisible demons. The interpretation of the impressions made by the "light" (i.e., deep ultraviolet, gamma and X-ray and other classifications of EMF radiation) emanated by the cloaked molecules of demons on and by the camera imaging sensor is different than that for natural (visible) light (while a camera imaging sensor can detect both, the processor that creates an image from the impression data is geared towards natural light). Even so, the impressions are still there, and its just a matter of developing processes for finding them and assembling a decent image out of it. Second only to the processes associated with acquiring the impression involving the camera,   is frequency separation. More often than not, demons are found in the frequency domain  representation of the image data acquired by the sensor (versus the normal, spatial representation where objects native to our environment are found).

Why would that interest me?
Although any image that reveals even the faintest, blurriest, smallest vestige of a demon has plenty in it (i.e., tells you all you need know), it's still worth it to take a closer look. Demons often wear jewelry and bear insignia and sigils on their clothing, all from their world—not ours—and all unique.

What can I expect by using it?
The following images demonstrate a cross between revealing cloaked entities in the frequency domain and making regular, everyday enhancements made to regular, everyday things you see in images:

NOTE | The video (above) demonstrates a unique benefit of separating images of the demonic into high and low frequency components, specifically, revealing demons that can only be seen in that way (those were the very small ones that could only be seen close up).

Even images with plenty of detail (left) can still benefit from the depth added by frequency-separation filters (right), as well as from the separation of detail and texture from color and tone  [see Frequency Separation Retouching Tutorial in Photoshop  | PhotoshopCafe]
The sharp detail and vivid contrast in images such as these are hard to come by with the long-duration exposure/panning technique used to make them, which makes image-processing filters like the Hi-Lo Pass Sharpen indispensable for demonic imaging (moving the camera while the aperture is open smudges the image, but it is necessary to reduce the impression made by natural light on the imaging sensor and make room for the "light" from the otherwise invisible demon cloak to leave its impression in its place)

What about the process that comes before? How do I do that?
The process for making images of cloaked demons can be demonstrated in approximately 7-10 minutes by live video chat. To do it yourself, you'll need an iPhone to run the camera app (which enables long-duration exposure and ISO configuration) and a Mac with Xcode installed to build the app (its not distributed via commercial means). The source for the app is on GitHub at:


NOTE | Demonstration of the build process also takes about as long.
