Latent Print Adobe Photoshop Series Part 3:  Working with Adjustment Layers - Channel Mixer
By Steve Everist,
King County Sheriff's Office - Seattle, WA

Adjustment layers provide the functionality of making image adjustments while not working directly on the image itself.  Many of the features available in the Photoshop Image – Adjustments menu are also available as an adjustment layer.  In this example, I will use the Channel Mixer adjustment layer with an inked print on a check with a light blue background.  Before using the Channel Mixer adjustment layer I would simply select the blue channel to see if it will filter out the unwanted background noise in the image.  In this case it works nicely.  But for those colors that share elements of red, green, and blue; there is more control to be had by adjusting all three of the channels within the image.

I’ll start with a scan of the image.  In this case it was scanned at 2400 ppi at 16 bits in RGB color.
 


Next I will go to the “Create new fill or adjustment layer” icon in the Layers palette.  It is a black and white circle in the middle of the bottom of the palette.   


Clicking this icon will bring up the adjustment layer menu with the different layers that can be used.  I’ve selected the Channel Mixer layer.
 

The Channel Mixer box contains sliders for the Red, Green, and Blue channels along with a constant.  Be sure that the Preview box is checked so that you can see the changes as you move the sliders.
 


Next check the box marked Monochrome.  This will allow the image to be visualized in grayscale, although the underlying image is still in RGB.  In this example, the print has almost disappeared on the image.  This is a result of the default setting for this box having Red at 100, while Green and Blue are at 0.

 

 
At this point, I have moved the sliders to a point where much of the background noise has been eliminated. 
 


To compare it to the original image, all I have to do is click the eyeball next to the new adjustment layer, in the layers palette.  This will show the image with and without the adjustment.  All changes happened on a layer above the image. 

If it is decided that further adjustments to the layer are necessary, I can just double click the Channel Mixer adjustment layer icon in the layer adjustment, and the Channel Mixer box will pop back up with the current settings.  At this point I can continue to move the sliders.

Adjustment layers provide the same features for clarifying images that can be found in the Image – Adjustments menu, but with the added features of not working directly on the image itself, being easily changed, and not requiring going back in history if the changes don’t offer any significant improvement and other avenues are desired.
