TECHNOLOGY | Photoshop action for revealing demons in the dark (or not)

12 Nov

This is a draft of an upcoming post on processing photos and videos showing demonic possession. Check back often for updates.


A Photoshop action is currently in development that automates the procedure for revealing a possessing demon in a video or photo of the subject sitting in near total darkness; it is intended to expedite the application of a procedure comprised of a significant number of steps, and is particularly useful for processing videos of demonic possession, as it can be quickly and easily applied to still frames, which often number in the hundreds or thousands:

The first few steps of many in the Reveal Demon-in-the-Dark Photoshop Action

To work properly, the photo (or video) should be made with an first-generation iSight camera while the subject is sitting in front of a Mac so equipped in a completely dark room, with only the screen providing illumination. The brightness must be set to full, and the screen saver must be dark enough in color to conceal the persons face almost completely.

It is the relatively monotone coloring of the demon and the separation of color channels in a digital image that enables Photoshop to isolate only the parts of an image that comprise the demon:
The demonic cloak usually projects red color, but is sometimes green, as shown in the color channel separation image, above; regardless of its color, the image of the demon can be enhanced by applying the requisite adjustments to only the channel in which it is visible
When applying the tone and contrast adjustments to all channels (red, green and blue), the processed image would look like this:

Without first isolating the demon by color, adjustments made to the image will mix the face of the human with that of the demon

It is the contrast in brightness between the polarized light from the cloak of the demon and the reflected light from the surface of the human’s face enables Photoshop to exclude the human by narrowing the tonal range of colors in the image to that of the demon:

When adjustments are made to the color channel that contains the parts of the image that comprise only the demon, the underlying human face is revealed

Without the distinction made polarized light and reflected light, and absent the capabilities of Photoshop, the image of the demon is concealed, as it is in the original image:

The original image, without any adjustments applied

In addition to increasing the visibility of the demon while excluding that of the human via adjustments to the tone and contrast of the color channel in which the image of the demon is naturally isolated, the action performs—or will perform—the following steps, in general:

  • smooths the texture of the demon’s skin (blending and blurring the visible areas of the demon’s skin until they overlap the dark spaces between)
  • adds realistic texture to the skin (superimposing the original texture of the skin over the smoothed areas, minus the dark spaces between):
  • sharpens the edges of the face and facial features:

    The Reveal Demon-in-the-Dark (green channel) action was applied to this video:

    These are the (messy) notes I’m working from right now, as I complete and refine the action:

    Adjusting Brightness and Contrast

    1. Duplicate the original layer.
    2. Adjust levels to 0, .47, 31.
    3. Create a Channel Mixer adjustment layer.
    4. Set the blending mode of the adjustment layer to Color Dodge.
    5. Select the duplicate of the original layer, and then apply Auto Contrast.
    6. Fade it by 50 %.
    7. Select the adjustment layer, and then merge down.
    Reduce Noise layer
    1. Duplicate the merged layer.
    2. Apply the Median filter (1) to the duplicate layer.
    3. Apply the Dust & Scratches filter (1 and 1) to the duplicate layer.
    4. Set the blending mode of the duplicate layer to Luminosity.
    5. Merge the layers (Merge Down).
    6. Duplicate the new merged layer twice.
    7. Apply a posterize adjustment layer (30).
    8. Select the topmost merged (or posterize-adjusted) layer.
    9. Apply a posterize adjustment layer (32).
    10. Select the topmost merged (or posterize-adjusted) layer (again).
    11. Apply a threshold adjustment layer (2).
    12. Merge the adjustment layers with the new merged layer.
    13. Apply the Gaussian Blur filter (3.0)
    14. Set the blending mode to Exclusion.
    Reduce Noise channel mask
    1. Merge Visible, and then duplicate the merged layer.
    2. Copy the original merged layer, and then save it to an alpha channel.
    3. Load the alpha channel as a selection, and then select a duplicate of the original layer.
    4. Select the white color range, while subtracting black (Select | Color Range).
    5. Invert the selection, and then clear it; deselect it.
    6. Duplicate merged layer.
    7. Apply a Gaussian Blur (3) to the duplicate merged layer.
    8. Duplicate the blurred duplicate merged layer, and then invert it, and then set the blending mode to Difference.
    9. Set the blending mode of the original blurred duplicate merged layer to Luminosity.
    10. Merge these three layers, and then copy it to a new alpha channel. This layer will be used to sharpen/smooth edges. (When automating the use of an alpha channel, delete the channel after each use.)
    Sharpen Edges layer (using a channel mask)
    1. Create two transparent layers.
    2. Create a channel mask using the Reduce Noise layer,
    3. Load the channel mask as a selection, and fill the top transparent layer with white; invert the selection and then fill the layer with black.
    4. Select the bottom transparent layer, and then fill it with black; then, invert the selection, and fill it with white.
    5. Set the blending mode of the top transparent layer to Exclusion.
    Sharpen Edges channel mask
    1. Stack the Reduce Noise layer over the Sharpen Edges to simultaneously smooth texture and sharpen edges using the Median filter.
    2. Set the blending mode of the Reduce Noise layer to Exclusion.
    3. Merge the two layers.
    4. Copy the merged layer to an alpha channel, and then load the channel as a selection.
    5. Select the duplicate of the original (or is it the original) layer, and then apply the median filter…

    To run this action for each frame in your video file, create this Photoshop script (using ExtendScript Toolkit), but substitute the name of my action and action set with that of yours (in bold):

    var docRef = app.activeDocument;
    function recurseLayers(currLayers)

    {

         for(var i = 0; i < currLayers.layers.length; i++)

         {

              docRef.activeLayer = currLayers.layers[i];

              if(isLayerSet(currLayers.layers[i]))

                   {
                       recurseLayers(currLayers.layers[i]);                   
                   }
             app.doAction (“[action]“, “[action set]“)
         }

    }

    function isLayerSet(layer)

    {

         try{

              if(layer.layers.length > 0)

                   return true;}

         catch(err)

              {return false;}

    }

    recurseLayers(docRef)
