Step 1: Exposure

Exposure is simply the time while light is falling on the sensor. The longer is it, the more light will get to sensor. In Raw conversion the exposure should be changed maximally to +1,5-2,0. Using higher values is not recommended. You can see that the image was brightened after this adjustment.

Step 2: Recovery

Step 6: Vibrance and Saturation

This options work with the color balance of photo. There is an essential difference between them. Saturation saturates or desaturates all colors in the whole photo. Null saturation means black and white photo and in case of increasing saturation you risk overexposed colors (you will see clipping and colors will look strangely). Vibrance only saturates colors which are not saturated yet. Not saturated colors are saturated more than the saturated ones so you cannot get overexposed colors so easily. This is very often tool for adjusting the color of face.

Step 7: White Balance

One of the essential advantages of RAW format is to change the white balance in computer. You can choose from predefined options or you can manually set temperature and hue of colors. The automatic option tries to balance the white color according to the real temperature and hue of light.
