Practical Application
Areas of application for the ND 3.6:
- Daylight Exterior Shots: Wide-aperture shots in strong sunlight
- Long Exposures: Motion blur in bright lighting conditions
- Depth of Field Control: Wide apertures despite high light intensity
- Overexposure Protection: Avoiding clipping in bright image areas
