This man had a yellow tint to him so I used the white-balance tool to even him out. I played around with basic editing to make the picture look better, like lowing the clarity and contrast and bringing up the exposure and shadows. I healed the few blemishes he had on his face and softened the lines around his eyes. With the pen tool, I whitened his teeth and the whites of his eyes. I burned his pupils and the circle around his irises. I also enhanced his irises and made his eyes brighter.
Abused lady
This woman needed a lot more work. To start, I used the white-balance tool to even out the picture. I didn't do any basic editing and just started healing her skin. I also fixed and shaped her eyebrows with the same tool. With the pen, I softened the skin under her eyes, her nose, and her chin. I brightened the skin under and around her eyes to make her look less tired. I also took the burn pen to darken and further shape her brows and to darken her eyelashes. I whitened the whites of her eyes, darkened her pupils and brightened her irises. Lastly I decided to slightly change her hair colour, I gave her blonde hair more of a red tint to make it look less boring.
Barcelona Landscape
To edit this photo I started by lighting up the shadows of the rocks in the foreground. I also increased the clarity and exposure. Then, I highlighted the sky and edited it to make it more blue. I made the mountains in the background more clear and saturated. Later I lightened all the highlights in the rocks and bushes that you see up front.
