Picture to people now has a new category of photo effects.
Now you can improve the color distribution of your photos.
In some cases, the quality enhancement is amazing.
Beware if you improve the color distribution of some kinds of bad quality and/or noised photos, the result can be even worse, since you will "increase the bad". Anyway, it works very well for a large group of images.
Above you see a photo and the color enhanced result.
