Lighting your background properly is key especially when it comes to shooting for e-commerce clients who need a pure white background. Saving this for photoshop is time consuming and not ideal. What if you can get a pure white evenly lit background with almost no effort? Sounds too good to be true, but it isn't.
V-Flats can be used in lots of different ways, from adding light to subtracting light and even as a posing table by some photographers. But one of the most practical uses has to be lighting a background. Because they offer such a large white surface area, it makes for a huge light bounce source. It's as simple as pointing a strobe directly into the V-Flat. You can decide how much you want the light to spread by opening up or closing the V-Flat.
