How to Isolate Specific Color Shades in Photoshop

In this post i'll teach how to isolate specific colors using the Color Range feature in PS. Like the posters below of the movie The Spirit, you notice that shades of red are emphasized on an otherwise black&white photo.

1. Open the image you want to edit.

2. Go to Select>Color Range>Click Reds on the drop down box.

3.It'll automatically highlight the areas which is of the specific color shade you chose.
4. Copy & Paste (Ctrl+C & Ctrl+V), it should create a new layer. Click the base layer (Layer 1) and go to Image>Adjustment>Desaturate (Ctrl+Shft+U).

Just flatten the image, Layer>Flatten Image then adjust the contrast to get the desired effect. And there you have it!
