The Manfrotto Joe McNally Uplite Kit is similar to the standard cool tone Uplite but with an important addition: a 2 stop diffuser panel.
Like the cooltone Uplite, two 3 x 4’ lightweight frames clamshell together with a joint at one end. The reversible Sunlite/Soft Silver and Silver/White reflective materials stretch over the frames. Of course, since you’re bouncing fill light up onto your subject, the topmost fabric will determine the quality and color of the fill. Directing the fill is easy thanks to the 30 – 80° adjustable bracket. There’s a waterproof cover for the base for wet environments.
Joe likes to replace the reflective fabric with the included 2 stop diffuser and shoot through it with his choice of strobe or small flash. This effectively turns the Uplite into an “active” fill source rather than a reflective one. Color balance of the fill is determined by how imaginatively you gel the flash
