I do not know what to say, except that I was wrong to do without it for so long. I experimented with a baby positioned sitting in the shade of his stroller with a rear sunny plane, using the gold reflector side directed at him. His face also looks sunny, and when I rule to expose properly, the background is not (or at least much less) overexposed. I intend to set up a small studio at home, where will this purchase its place too. Once folded, it is not very compact (40cm in diameter), not very heavy and very easy to use, this is a "must have".
