Saturation - Controls color saturation with a higher concentration on light and shadows, higher values more saturation. Does not reset color from primary color photos.
Saturation 2 - It has a greater impact on the overall color of the image, even increasing the vibrancy of colors. Ideal to use in conjunction with Saturation 1.
Contrast 1/2/3/4/5:
Contrast 1 Higher values make photos lighter, but excessive values cause light blur in dark areas. Lower values decrease photo clarity.
Contrast 2 It works on the vibrancy of colors, higher values result in a higher color contrast. More vibrant colors, lower values, more washed colors
Contrast 3 Controls lighting contrast, lower values lighten the photo and flatter, higher values cause stronger black levels.
Contrast 4 Changes the lights at the structural level in the photo, high values force a strange structure in the image. It is not a commonly used tool.
Contrast 5 Controls color, vibration, high values cause extremely vibrant colors, in general it should be a saturation control, not a contrast.
