I switched over to mostly using fluid head video tripods for stills photography about 8 years ago. I still have a couple of Manfrottos with ball heads. I also use ball heads with sliders. But, my go-to is a Libec video tripod with a fluid bowl head. They just make life so much easier, especially on location.
It seems I’m not the only one who prefers to work with video tripods for photography, either. In this video, photographer Hudson Henry talks about why he likes to use fluid heads for photography. The advantages he lists are some of the reasons why I also like to use them. If you’re shooting a lot of video anyway, it definitely makes a lot of sense to make the switch, even for stills.
