I always have this problem whenever I use my pop up flash (I cant afford to own an external flash yet) as fill light, the skintone color turns out to have a gray cast and get really muddy looking. Particularly the shadow, it looks a bit greenish and noisy which I hate a lot.
Is this caused by direct flash or improper exposure?
Here is some example you can refer to
The left photo is straight from raw , right photo is pp-ed
These photos were taken during anime asia festival recently.
Someone posted a series which I think the skintone is great.
Please let me know what should I do so that I can get this kind of skintone (or avoid bad skintone).
