Photographic umbrellas are the simplest and most inexpensive form of light modifier available and that makes them the most popular, too. Photographic umbrellas look and act just like rain umbrellas except they’re reflective and light is bounced into or shot through them, creating a big, soft light source that’s aimed at the subject. And size does matter. As photographers we live by a few important lighting rules: the closer and larger a light source is to a subject, the softer the lighting effect will be. Conversely, the smaller and further away a light source is from the subject, the harder the lighting becomes. That old lighting rule that “size matters” is important here because a large umbrella is going to produce broader, softer light for your portraits.
