One of the powerful - and unique - features of the Sigma Photo Pro software included free with Sigma digital cameras is Fill Light. This adjustment tool allows users to shift the light balance in both the highlights and shadow areas at the same time. The result is outstanding recoveries or unusual effects. Positive Fill Light tends to brighten shadows and darken highlights. Negative Fill Light does the opposite.
