1- Open the image you wish to “glamorize”. Now duplicate it. Layer, Duplicate Layer
2- On the top layer go to Filter, Blur, Gaussian Blur. Try 25-50 pixels for 6 meg images.
3- Still on the top image go to Image, Adjust, Brightness and Contrast. Try +15% on both for starters.
4- On the Layers Menu select Overlay. In the pull down menu it is at the top left hand side. It will probably say Normal. Scroll down to Overlay.
5- In the Layers menu simply Flatten Image and save.
Here is a before and after. Pretty easy to do, to a larger or lesser degree. Try it.
