Coogee Pink
This one of the image that cokin really play it part. Total of 5-6 filters were used. Because of the bright nature of that particular sunrise, two set of ND were used ND4 (153) and ND8 (154), two set of Grad ND8 121M and 121 to bring down the sky. Lastly, 124 Tobacco Grad (with custom white balance) was used to give it the soft pink appearance.
