Full Dynamic Range Photography
How to capture the range of tones, from dark shadows to bright highlights, with traditional filters and HDR software
Also resembling on-lens grad ND filters, you can determine where you start and stop the line of ND delineation by dragging the start-stop lines in ACR. However, in ACR, you also can expand or compact the length of the ND gradation and that, too, offers the precise control a physical filter can't provide.
In HDR Efex Pro 2, in a section entitled "Finishing," the Graduated Neutral Density sliders offer Upper Tonality (the upper areas of the composition), Lower Tonality (the lower section in the image), plus Blend, Vertical Shift and Rotation, once again giving you ultimate grad ND tweak control of your photograph.

Some new to outdoor photography falsely assume techniques like grad ND filters or HDR imagery can be used virtually anytime. That's just not true. The goal is to choose the appropriate tool for the given situation. Light and contrast play critical roles in the decision to add a filter or create an HDR; so does exposure. Without the proper knowledge of utilizing the right light or metering the scene well, you can blow both processes.
