High Pass Effect in Photoshop

August 5, 2008

In this High Pass Effect in Photoshop Tutorial I hope to explain how you can create the similar effect.

With the below image I wanted to create a dream like, in the past effect, and in this tutorial I will attempt to explain what I did and how you can also do it. This technique is very simple and can be used and manipulated for lots of other things.

Below you’ll see I used a motion blur - although this tutorial is on blurring, you can adapt it to change the background colour but keep the girl the same. All you have to do is think outside of the box and play.

Feel free to request something similar to this High Pass Effect in Photoshop Tutorial.

High Pass Effect in Photoshop Tutorial - The Steps

  • Firstly open up the image you want to use for this tutorial (you can use the image above to try this out), if you don’t know how check this tutorial out.

  • Firstly you need to make sure you have your layers palette open. To do that go -> Window -> Layers - “Layers” should be ticked - Once you have done that, locate your layers… look at mine!
  • Now go to your layers palette If you look at it closely you’ll see three small tabs; Layers, Channels, Paths - Select Channels you’ll see four channel layers, just like mine here - now you can select one of the layers; I selected red but this was just because it suited the image best.
  • Once you select red you’ll notice a change in your image… so then go to your image and use these shortcuts: CTRL (win) / Command (mac) + A (selects the image) - CTRL (win) / Command (mac) + C (copies the image) - then click the RGB layer, and then click the layers tab (before you selected “channels”)…
  • When you see your normal layers and your image in colour, use this shortcut CTRL (win) / Command (mac) + V (this then pastes the red, grayscale layer onto your colour one).
    • Now, still in your layers palette, change the mode to screen
    • Now merge your layers together. Layer -> Flatten Image.
    • You should now only have one layer - now duplicate it. I always use the shortcut: CTRL (wind) / Command (mac) + J
    • Now go -> Filter -> Other -> High Pass - High pass is basically a sharpening tool - I changed my Radius to 4.0 but you can do more or less. Your image should now look very odd… now go to your layer and set it to Softlight - with high pass I sometimes set the layer to Overlay, Screen, Hard light or like I have done this time, Soft light… whatever works for you.
    • Aaandddd you’re done. It’s simple but useful, I find. I hope this High Pass Effect in Photoshop Tutorial was helpful - however if you have any questions regarding this tutorial then please leave a comment below and I’ll happily reply. :blink:
