Portrait photos are not my preferred; I do basically outdoor and landscape photography.
But last Christmas, after a pantagruelic lunch and a lot of wine, I took some indoor shots to my family, without flash (I don’t like it) and with very high ISO settings. Also I tried a couple of B&W shots. Then, at the end of the day, I realized that the camera was set to JPEG only mode…
Lesson learnt: if you plan to take shots early in the afternoon, keep the wine aside at lunch
Anyway, I tried to play with one of them in PP to soften the skin of my niece using the Wavelet Decomposer plug-in in GIMP. Not very user-friendly, but quite effective, I believe.
Here the original JPEG and the result of PP for your C&C.
