this screen shot is off whose computer ? ask that person would be more productive. personally the skin from what is shown here look too much brighten - it is almost at point of losing color and detail - what some call the taiwanese bridal studio treatment.
There are presets that is similar to the editted pics.. i am using Seim Effects.. u can download some free samples from his website.. alternatively, just play around with the settings to get what u want and set it as ur presets..
The girl in one. Just some curves adjustment for the (yawn) tiresome-done-too-often "Taiwan wedding studio" luminous effect.
Overused to the extent that it becomes cheapskate.
The rest in another. The two swimmers removed from the sea. Exposure adjusted to reveal the sand texture.
Adjustment is basic. No fantastic secrets.
