The PROMASTER SPEEDLIGHT SOFTBOX creates pleasing portraits by softening your speedlight’s illumination. Its internal baffle can be adjusted for softer light. The special bounce feature works by directing a main light towards the ceiling (for a large, soft fill) while the open bounce panel directs some light forward to open shadows and make your subject stand out.This softbox has a universal fit which works with most speedlights. It is fast and easy to set up. After use it folds flat and stores in an included pouch.
