I recently purchased a small shoot through umbrella softbox.
I love the light it produces, but you can’t tip it to shoot down on the subject
from above. It set’s too close to the light stand (photo-01). If you try to tip
it down it’s hits the light stand. I user two Phottix umbrella mounts to form
two adjustable “L” brackets (photo-02). The brackets are connected with a short
piece of half inch hard copper tubing (photo-03). By adjusting the “L” attached
to the light stand you can make the umbrella softbox point up. By adjusting the
“L” attached to the speed light you can make the umbrella softbox point down.
