Comments about Hensel Hensel Master White Umbrella with Parabol 80cm:
This is brilliant little gadget. Sets up in seconds, and gives you quality of light that is surpassing regular umbrellas.
White internal material isnt your usual satin, so it can be cleaned with cloth.
Ribs supporting rods are a bit too light - so if whole thing falls even when no strobe head attached - they can bent. So watch out for winds if shooting on location.
Overwise - the only thing that comes to quality of light even close - Deep Octa from Elicnhrom. Except you cant use it without speedring and such, so this umbrella is total winner in my opinion, specially if you shoot on location.
Gives gorgeously soft, yet concentrated light with that special "punch" of contrast.
