Hot and Fiery Effect
In this example I am going to make hot and fiery effect on the photograph,
this effect is just like a person is standing around the fire. Let's star
learning.
Step 1: Take any person picture, I have a beautiful lady picture to modify.

Step 2: Make color effect, go to Image menu > Adjustment >
Hue/Saturation and set values as here.

The picture will look like this.

Step 3: Make duplicate layer and set blending mode as here.

Step 4: Now make again duplicate layer set blending mode "Normal"
to "Soft Light". as given below.


Step 5: Take a new layer and fill any color as you like then go to Layer menu
> layer style > gradient overlay and make color settings.

"Overlay".

This is the final result.
