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.

It’s called “continuous lighting” because it’s on continuously, much like a light bulb or the sun for that matter, enabling you to use your in-camera meter to measure the light falling on your subject. Continuous lighting lets you see how all of the light—shadows and highlights—is falling on your subject, but continuous sources sometimes use quartz or photoflood bulbs that can be hot, even dangerously so, leading to the use of the term “hot lights” to describe them. An increasing number of continuous lighting tools are now being made using other kinds of light sources, even LED, producing cool “hot” lights. And that brings us to the subject of this review—the Calumet (www.calumetphoto.com) Pro Series LED Panel Light.

Pentax has a long history of innovation as well as a rabid fan base that loves the company’s tradition of optical excellence and originality. In fact, this fan base is the reason I’m writing this review. If you’re not already a Pentaxian you probably didn’t know that Pentax (derived from PENTAprism refleX) built the first camera to incorporate a penta-prism viewfinder and reflex mirror system in 1957 and went on to introduce the first TTL metering system in 1964. While late to the digital SLR game, when they finally arrived it was with a series of entry-level cameras that delivered impressive image quality at affordable prices. Over time they’ve dipped their toes into the semipro market and the K-5 is the latest model with professional aspirations yet it retains all the quirky uniqueness that all Pentax cameras have and that endears them to so many photographers.
