Concept: The is the simple most type of image enhancement using layer blending mode of Adobe Photoshop. We have used overlay mode to turn simple pale looking photograph into a vibrant enhanced image. You can experiment with different layer blending modes. You need to control the degree of blending to control the enhancement because it may look too fancy and unnatural if there is a lot of glow and light into it.
1. Open Photoshop. Open an image to
try retouching commands.
2. Drag the background layer on the red marked icon
of the layer palette, which says "Create a New Layer"
3. Background layer is duplicated.
4. Change the properties of background copy layer.
Change the blend mode to Overlay and opacity 63%
5. The image is retouched. It is clear and sharp.
