Color-Grad can transform an average sunrise or sunset into something spectacular or convert a dull, washed-out sky to a breathtaking blue.  No other filter has done so much to improve landscape photography as the graduated filter.  Add color selectively while leaving the rest of the scene unaffected by using a graduated transition for a smooth color blend between the colored portion and the original image.  Presets for your favorite Color-Grad filters are provided as well as the ability to create custom colors.
