To achieve a "high contrast, grainy, almost cool grey-blue look", try following these steps:
- Choose your image. I chose one of my favorite bouldering pics.
- Use a couple of adjustment layers. For this look, I used levels and Hue/saturation.
Here's how I used levels. Really play around with this adjustment (it's my favorite one). You can take an image from flat to almost polarized if you want. It's a really rad feature.
Here's how I used the hue/saturation adjustment. For this look, you probably just want to lower the saturation until it looks roughly like how you want.
- Now create a new layer and color some shade of blue. You probably want something trending towards the navy range so it's not too bright. Now take the opacity of that layer way down. I used 10%.
- Now for that grainy look. For this, I just used the sharpen tool. I like to use a big brush size and do little sections at a time so I can see how it looks. You can go over the same section multiple times to get a grainier look. For this image I passed over the climber about 5 times and the landscape roughly 3.
Hopefully this helps you get the look you're going for. :)
To add those "electronic frequency" lines, you could overlay a photo similar to this one
Desaturate the lines and apply an overlay to achieve this effect
