Black-and-White Infrared Film

Just follow these steps.
1. First, select the sky area of the image. Press Q to enter Quick Mask mode, and paint around the
sky area with a soft brush


2. Press Q again to exit Quick Mask mode, then press Ctrl/Command
+ J to copy the sky into a new layer. Double-click the layer to activate Photoshop’s renaming
mode, and name the layer Sky.

3. Press Ctrl/Command + S and save the file as infrared.psd to preserve your work so far.

4. Double-click the background layer and name it Castle.

5. Choose Layer > New Adjustment Layer > Channel Mixer, and click on OK
when the New Layer dialog box appears. The Channel Mixer dialog box should pop up.


6. To mimic the infrared effect, we want everything that appears as green in the
image to appear much lighter than normal (because living foliage reflects a lot
of infrared light), but in black and white. Click on the Monochrome button
to apply the changes we’re going to make to a grayscale version of the layer.

7. Lighten the green portion of the image by boosting the Green channel to 200
percent (the maximum allowed by Photoshop). Move the Green slider all the
way to the right.

8. Reduce the amount of red by moving the Red slider to the left, to about
–80%. Click on OK to apply the change


9. Click on the Sky layer and Choose Layer > New Adjustment Layer > Channel
Mixer to create an adjustment layer for the sky.

10. Move the Red slider to the right, to about 90%, and then click on OK to
apply the change.

11. Save the image with the adjustment layers intact. You can reload the image at
any time and make further modifications with the adjustment layers.

12. Flatten the image and save it under a new name.
