The last few days I trying to classify my old digital images and those which are poor quality I will try to fix again using the Photoshop CS3 software. Some of the pictures have bad lighting, some of them have too much light from the flash but main problem that I found is faces of the people with lot of scars, acnes and different colors on them since this photos date even back in my teeneger days (which can be funny but sometime it is just to annoying). To remove scars and clean faces in Photoshop CS3 (or any newer version) you need only couple of moments so follow the next instructions that I wrote in my blog :
