LumiQuest's Softbox LTp (10 x 14") is a very large softbox designed for use off-camera with a portable speedlight. The surface area of the LTp (140 sq. in.) is more than 40x that of the flash itself, which spreads the light further, producing softer shadows than smaller softboxes. The LTp is designed exclusively for off-camera use. Folds to fit a laptop pocket in a camera bag.
