Snoot

A snoot is a tube-shaped modifier fitted over a flash or studio strobe. It narrows the light to a small circle, so only one part of the scene is lit and the rest stays dark. Photographers use it for hair lights, rim lights, background spots, and small highlights on products. Snoots come as simple metal or fabric tubes, tubes with a honeycomb grid on the front, and optical snoots with a lens for sharp-edged circles.

A snoot is a tube. It blocks light from leaving the flash in any direction except straight ahead, and the length of the tube sets the spread. A grid is a flat honeycomb panel. Light passes through many small cells, which trims the spread while keeping a wider, softer-edged beam. Snoots produce a smaller and harder spot than grids. Many photographers fit a grid on the front of a snoot to get the tightest, cleanest circle.

An optical snoot is a snoot with a lens at the front. The lens focuses the flash into a circle with a sharp edge, and the size and sharpness can be changed by adjusting the lens. Most optical snoots have a slot for a gobo, a metal or glass slide with a cut-out shape, so the light can project window frames, leaves, or letters onto a subject or wall. They cost more than a plain tube but give far more control.

Use a snoot when only a small area should be lit. Hair lights, rim lights, background spots, and detail highlights on products all call for a snoot. Use a softbox when the goal is soft, even light across a face or a whole subject. The two modifiers do opposite jobs and often work together in one setup: a softbox as the main light and a snoot as the accent light behind or above the subject.

Roll a sheet of black card or craft foam into a tube and tape it around the head of a speedlight. A cardboard tube from a roll of paper towels also works when it fits over the flash head. Line the inside with black material so light does not bounce off the walls of the tube. A longer or narrower tube gives a smaller spot. Homemade snoots produce a spot with a soft edge, which is fine for hair lights and background glows.

Light gets softer as the source gets larger relative to the subject. A snoot does the reverse: it hides most of the flash head and leaves only a small opening, so the effective source becomes smaller. Small sources cast shadows with crisp edges and produce bright, tight highlights. This is why a snooted light on hair or a shoulder shows a sharp line between lit and unlit areas, while a softbox in the same position produces a slow fade.

It depends on the size of spot wanted. Closer to the subject the circle is smaller and brighter. Farther away it grows larger and dimmer, and the edge becomes softer. For a hair light, snoots often sit one to two meters behind and above the subject. For a background spot, the light usually sits close behind the subject, aimed at the wall, so the glow stays small. Test shots settle the distance faster than measuring.

Yes. A snoot blocks most of the light leaving the flash head, and a grid on the front blocks more. Expect to lose one to two stops compared with a bare head at the same distance. Raise the flash power, move the light closer, or accept a darker accent. Because snoots are usually accent lights, not main lights, the loss is often useful: a hair light at low power looks natural, while one at full power burns out.

Yes. Speedlight snoots are small fabric or rubber tubes held on with elastic or a strap. They work the same way as studio snoots and are popular for hair lights and background spots in home studios. Because a speedlight has less power than a studio strobe, keep the snoot within a couple of meters of the subject. Set the flash head to its telephoto zoom setting so the beam is already narrow before it enters the tube.

Snoots place a small highlight where the photographer wants attention: the face of a watch, the label on a bottle, or a single flower in a dark arrangement. The rest of the set stays at its normal exposure, so the highlight reads as a deliberate accent. Optical snoots with gobos are also used to project window shapes or patterns onto a tabletop, which suggests a room or a time of day without building a set.
