Taking photos in the sun without a fill-light or reflector often result in dark shadows. To fix this issue you can use the adjustment brush in Lightroom and lighten up those areas or… you can use this preset which also gives another great effect. As you can see it brings a nice overall warm “pinkish” (nice word btw) tone to the photo. To me this kind of style looks more fashionable than the original photo. Just look at the nice enhancement of the reflections in the sunglasses.
