RAW files capture what the sensor sees, yes. The advantage here is mainly that
you can then adjust certain things later without losing detail (such as small
exposure changes, white balance, etc). This is because the RAW files are
captured at greater bit-depth than the JPEG files are stored at.
(ie. Nikon's sensor is 12 bit; JPEG files only store 8bits of colour, and
compress info too. The raw stores about 10 bits of colour info apparently.)
