This is the image that I chose on photoshop experiment on. This is a girl with acne, by using the tools on photoshop i was able to remove her spots and reduce the redness on her face. This helped me to create clear looking skin.

 i did this by using the clone stamp tool to try and make her skin look clear. I pressed ALT and selected on a clear part of her skin and was able to place it over the acne making her skin look clear. i had to be careful and made sure the skin matched and looked even, I was also able to reduce redness on her face.
