Very useful, especially for portraits to lead the shadows. Easy to store and takes up little space, which is especially useful when traveling. Side silver or white for the interior near a window for example, gold or face outside when there is sunlight. The translucent veil can serve as a window to get a soft diffused light. I do not see the point of the dark? The only thing I regret is not having bought earlier. Note: To store the reflector in his bag, one must twist by making a 8, then fold it in half to put the two loops one in front of the other (explanation video on YouTube).
