Greg Benz is a cityscape and landscape photographer located in Minneapolis, Minnesota, USA. Greg’s photos focus on dramatic lines and light, to convey a sense of mood and place. While he has called Minneapolis home for over 10 years, his work includes a broad range of destinations around the world, having traveled to over 70 countries. His goal is not just to create art, but to connect with other photographers to share the vision, tools, and technique behind his work. Greg uses luminosity masking techniques extensively, and has created the Lumenzia extension panel to help simplify the process of creating subtle and natural masks to empower photographers to create amazing images with Photoshop.

      • ND filters, I think a lot of people don’t use them or even own them.  Tell us why and when we should use them?

        • A ND Filter is like sunglasses for a camera lenses…reduces the amount of light for a longer exposure. 

        • Two reasons to use for Greg:

          • Ability to take a 5-10 minute exposure

          • Lens maximum sharpness is around f8…use ND filter to get to sweet spot of lens

        • Recommend 6 stop and 10 stop…stacked together to 16 stops
