You've probably seen professional photos and advertisements (especially sports ads) with a gritty, high-contrast look. Assuming you've got a well-lit photo, this effect is very easy to achieve in just a few seconds by blending a colour channel. Here's how.
The video above demonstrates the process for you, but here are the basic steps:
- Go into the Channels palette in Photoshop, select the green layer and copy it.
- Select the RGB composite layer in the Channels palette, then switch back to the layers palette and paste the green layer you just copied into a new layer.
- Set the blending mode of your newly pasted layer to Overlay.
- Dial down the opacity until you get the look you want.
