Lighting basics: types of light, modifiers and reflectors

By Jos James, A.P.E.L

Every studio session comes down to the same question: where is the light coming from, and what's shaping it before it reaches your subject? Once you can name the gear and know roughly what it does, reading any lighting setup — yours or someone else's — gets much easier. Here's a practical rundown of what you'll actually find in a studio, starting with the two families of light itself.

Continuous light vs flash

This is the first split every photographer needs to understand. Continuous lights stay on the whole time, like a very powerful lamp — what you see is what you get, which makes them easy to learn on and essential for video. Flash (or "strobe") fires a single, very bright burst timed to your shutter, giving you far more power for far less heat and energy than continuous light of the same brightness. Studios usually lean on flash for stills and continuous light for video, or for photographers who want to see the exact shadow before they shoot.

Types of continuous light

LED panels are the modern standard — cool to run, colour-adjustable, and available in everything from small on-camera panels to large studio banks. Tungsten ("hot") lights give a warm, traditional look but run hot and draw serious power, so you'll see them less often now. Ring lights circle the lens itself, producing flat, even light with a distinctive circular catchlight in the eyes — popular for beauty and social content. Fluorescent banks sit between the two: cooler than tungsten, less adjustable than LED, but still common in older studio kit.

Types of flash

Speedlights (flashguns) are the small, portable flash units that sit on or off your camera — flexible and battery-powered, good for location work. Studio strobes (monolights) are self-contained flash heads with their own power and controls, the workhorse of most studio setups. Pack-and-head systems separate the power pack from the flash head on a cable, giving more power and faster recycling for busy commercial studios, though you'll see them less at workshop level.

Shaping the light: modifiers

A bare bulb throws hard, contrasty light with sharp shadows. Everything that follows exists to change that.

Softbox — a fabric box that fits over the light, softening it into a broad, even source with gentle shadow edges. The bigger the softbox relative to your subject, the softer the light. The standard tool for flattering portrait light.

Umbrella — cheaper and quicker to set up than a softbox. A shoot-through umbrella is translucent white; the light fires through it toward the subject, spreading and softening as it passes. A reflective (bounce) umbrella, usually silver or white-lined, fires the light backward into the umbrella first, which bounces it forward — punchier and more directional than shoot-through.

Beauty dish — a shallow metal dish that gives light with more contrast and "shape" than a softbox, but still flattering — a favourite for fashion and beauty portraits.

Octabox — an octagonal softbox, prized for the round, natural-looking catchlight it puts in the eyes.

Snoot — a narrow tube that restricts light to a tight, focused circle, used for hair light or picking out a single detail.

Grid — a honeycomb attachment that narrows a light's spread without changing its softness, useful for controlling exactly where light does and doesn't fall.

Barn doors — hinged flaps on a light that fold in to block spill and shape a hard edge, common on continuous lights.

Reflectors

A reflector doesn't produce light of its own — it bounces existing light (from a flash, a continuous light, or the sun) back onto your subject to fill in shadows. Most photographers carry a "5-in-1" reflector: a collapsible disc with a removable zip-off cover, giving five surfaces in one piece of kit.

White — soft, neutral fill; the gentlest option, good for close-up portrait fill without overpowering the main light.

Silver — a stronger, more directional bounce with a slightly cooler, punchier look than white.

Gold — warms the light it bounces, useful for golden-hour outdoor portraits or adding warmth to skin tones.

Black — the one that surprises beginners: it doesn't reflect light, it removes it, creating extra shadow and contrast on one side of a subject when you need to carve shape back into a face that's getting light from everywhere.

Diffuser (the translucent centre panel) — held between a hard light source (often the sun) and the subject, softening it exactly like a shoot-through umbrella does with flash.

Putting it together

In practice, a typical A.P.E.L studio session might combine one strobe through a softbox as the main ("key") light, a reflector to fill in the shadow side, and a second, smaller light with a grid or snoot to pick out the hair or background. None of it needs to be complicated — knowing what each piece is for is most of the battle, and the rest comes from seeing it set up in the room and adjusting by eye, which is exactly what a hands-on studio workshop is for.
