Creating a "sunlight on face" effect

In this tutorial we'll create sunlight effect ( as if its coming from a window or from a grill ) on an old man face.

Start by opening an image in which you want to add sunlight.

From custom shape tool ( U ) select tile2.

Create tile shape on a new layer to cover the subject. Use some lighter color like white or pale white etc

From the layer pallete change the color mode of the shape layer to overlay.
Right click the shape layer and select rasterize layer.

Fro filter menu select blur>>gaussian blur.

 

Use blur settings as shown.
From the layer pallete reduce the opacity to 70%.
Select the lasso tool and make selection of outer area.
Press Ctrl+Alt +D to apply feathter on the selection.
Press delete to remove the selection area.
 Select the sunlight effect on the upper body of the old man. We'll displace it from its place a little bit to achieve some realism.
Press Ctrl+T to get transform handles.
Right click the transform selection and select warp.
Adjust the nodes of the image to apply a perspective look to our ligh and offset the lines so that they do not match exactly with lines on his face.
Here's the result. Looks like the old man is standing in front of a window from which sunlight is falling on his face.
