Photoshop Effect: Cyan tone in photoshop

Cyan is a very nice tone and it gives romantic look for your picture background . In this tutorial i will tell you some basic techniques to get that tone .

We will use this stock:

1. Use RGB Channel:
1a. Duplicate your base. Choose Channel, choose Green, Ctrl+A. Then Ctrl+C to copy it. Choose Blue, then Ctrl+V to paste into. Choose RGB and then come back to layer pallet. We can see the change of color from yellow into light cyan. We need to strengthen the tone.

1b. New selective color. We will see the result of these two ways, and depending on your pic tone you can adjust parameters. I just adjust difference of Cyan channel and let see the different results:
- Red:-45,-18,0,0
Cyan: 100,-36,-100,0
White:-30,-39,-23,0
Neutral:12,0,-26,0.
Black:100,100,100,0.

- Red:-45,-18,0,0
Cyan: 100,100,-64,0
White:-30,-39,-23,0
Neutral:12,0,-26,0.
Black:100,100,100,0.

2. Use Channel mixer:
2a. After duplicating your base, create new channel mixer layer:
Red:139,8,-22,-10
Green:6,105,15,0
Blue:0,146,0,-6

2b. New selective color to strengthen the tone:
Cyan:100,100,0,0
Blue:100,0,0,0
Black:100,100,100,0

Or: Color balance ( to compare the effect)
Midtones:-33,0,10
Shadows:2,-4,12

3. Use Lab color:
3a. Choose Mode-Lab color. Then duplicate your base. Choose channels, choose a channel then Ctrl+A and Ctrl+C. Then choose b channel and Ctrl+V. Choose Lab channel and then choose layer pallet. We have result:

Remember we cant save jpg format in lab color so we have to change color mode to RGB to save as jpg .

We need to brighten up the light on model.
