Sometimes it's good to bring a large reflector, like plastic
"cardboard", for fill and for wind control. Use straightened
clotheshanger wires to stick into the ground and thru the cardboard.
Or a white photo umbrella.
Loose sticks can prop a stem so it moves less.
An assistant, of any age, can be really useful as you run out of
hands.

You should be moving the camera to focus as the *last* step.
Not the right framing? then adjust the lens focus a bit, and then
move the camera again.

The reasonable man adapts himself to the world;
the unreasonable one persists to adapt the world to himself.
Therefore all progress depends on the unreasonable man.
