A Texture is also used for a dark grungy effect.
Links to the work files are provided for practice & effective learning.
There is no voice or text narration. This summary will help explain the process & technique.
On a Duplicate Layer, apply Gaussian Blur of 7.0. Mask this layer to hide the effect on the face & front body – paint on the mask with black Opacity 50%, Flow 63%. This creates a Bokeh effect to isolate the girl from the background.
Add a Black Solid Color layer, Opacity 83%. Mask this layer (similar to step 2) but paint further out to the background as this creates the scene lighting
Add the Texture. Transform & Position. Change Blending Mode to Soft Light, Opacity 83%. Mask this layer to hide the effect on the face & skin of front body – paint on the mask with black Opacity 22%, Flow 63%
Add a Levels adjustment layer & tweak the Black levels as shown
Add a Black & White Gradient Map, Opacity 75%
Add a Warming Photo Filter, Density 19%
Create a Composite layer (Ctrl+Shift+Alt+E) to merge everything into a single layer / copy
Duplicate the Composite layer. Apply High Pass filter, Radius 4.5 (you may omit the Smart Object step). Change Blending Mode to Overlay to see the Image Sharpening effect.
