When I see something on or close to the ground that I want to photograph, more often than not it is small; therefore, I’ll make a close-up or perhaps a macro shot. If I elect to stack images in this scenario, I’ve found that I spend less time repairing the artifacts left by any/all of the stacking programs if I use the most rigid set-up that I’ve found.
The Sachtler DA 100 K (not available in carbon fiber) has proven, for me, a real asset.
It has no click stops that can force you to raise the tripod higher than you want. The legs will spread to a full 90 degrees, the spikes are functional at that angle.
This tripod is rigid. When I’m in a reasonably sheltered spot (out of, or able to effectively shield the set-up from the wind) and tolerably firm earth upon which to place the tripod is available I’ve used a Cambo Actus XL 35 (or Ultima ) with a D850 on the rear standard and a heavy lens on the front standard (6.5 to 8Kg). I’ve obtained high quality images without resort to a pentapod or other form of improved support.
If the tripod has been in the mud, slime or sand cleanup is quick and easy- remove the head (or flat plate) then rinse the bowl and legs clean under running water. In a pinch I’ve swirled the tripod in a pond.
