Creating Light in Photoshop
(This tip was submitted by a user.)
Here is a tip that will help you to create light in Photoshop -- without flash, etc.
In Photoshop, process your image the way you normally do (levels, etc.).
Now you are ready to create light:
You've now created light -- exactly where you wanted it!
Duplicate the image, so you're not working on the original.
If you have more than one layer, flatten the layers.
Duplicate the background layer.
Set the foreground color to white and the background color to light gray.
Select the gradient tool in your toolbox, and from the options just under the main
Photoshop menu, select "Radial Gradient."
Choose an opacity of about 30, and check appropriate options for reverse, dither, and transparency.
Now, with radial gradient selected, draw a line on the face to create the over-used amount of flash effect desired.
Decrease the effect in the Layers menu with the opacity slider intensity and try different blending modes (normal, luminosity, etc.).
For my example below, I chose "Luminosity," and an opacity of about 79%.
Flatten your image.
Repeat the effect as needed.
