Design Polarizing Effects

Understanding how this polarizing effect works
Step 1
Download and save the following JPG file to your computer then open it inside Adobe
Design Polarizing Effects
vancouver.jpg 204.46 Kb (Right mouse click> Save As)
Step 2
Once you have the photo opened inside Adobe Photoshop, look inside the Channels pallet
Design Polarizing Effects
(Window> Channels). Inside the Channels pallet, click on the each of the channels and

notice the differences between the channels.

So the red channel’s characteristics are similar to those characteristics of a polarizing

filter (reduced reflections and darker blue skies & green vegetation), but how do we apply

those characteristics to the image? In the next page, we’ll teach you a fast and effective

way of simulating a polarizing filter.
Applying the Polarizing Effect
To apply the characteristics of the red channel into the entire image, we need to replace

the luminance of the entire image with the image from the red  channel.
Step 3
Open an image you would like to work with or use the vancouver.jpg file we still have

opened in Photoshop.
