Answer:
The salsa genre took form in the United States, and it may feature elements from all sorts of Latin American styles. In addition to Cuban son, salsa draws from Cuban danzón, rumba, guaracha, cha-cha-chá, mambo, and son montuno, as well as cumbia to Latin jazz.
Upping the contrast produces lighter lights, darker darks, and a wider range of tones in between—making your image look just a little better than what you’d see in real life. On the other hand, reducing contrast can give an image a more flat, even tone. As with saturation, too much contrast is usually not a good thing.
