The Complete Guide to Smoke and Atmosphere Effects for Film Production
Atmosphere is one of the most powerful tools in a cinematographer's arsenal. A perfectly lit scene can feel flat and lifeless without it, while even a modest set comes alive with the right haze, fog, or smoke effect filling the frame. Atmosphere adds depth, reveals light beams, creates mood, and sells the visual story in ways that no amount of post-production can replicate.
At SPFX Supply, we are one of Canada's leading distributors of professional atmosphere equipment and fluids. The Viper NT is probably the most-used fog machine in the Canadian film industry right now. We service dozens of them every season through our Toronto shop. This guide covers everything you need to know about smoke, fog, and haze effects for film and television production, from choosing the right machine to selecting the correct fluid and maintaining your equipment for years of reliable service.
Fog vs. Haze vs. Smoke: Understanding the Differences
These three terms are often used interchangeably on set, but they refer to distinct effects that serve different creative purposes. Understanding the differences is essential for communicating with your director of photography and delivering the exact look they want.
Fog
Fog is a thick, opaque cloud that sits low and rolls across surfaces. It is the effect you picture when you think of a graveyard scene, a swamp, or a mysterious alleyway. Fog machines produce dense output that is visible as distinct clouds and tendrils. The output from a fog machine is concentrated and dramatic, making it ideal for scenes that call for an obvious atmospheric presence.
Professional fog machines like the Look Solutions Viper NT produce high-volume fog with precise control over output density and timing. The Viper NT is the industry workhorse for film and television, delivering consistent fog output that can be dialed from a subtle mist to a dense wall of fog. Its powerful heater ensures rapid heat-up times and reliable performance across long shooting days.
Haze
Haze is a thin, even suspension of particles that fills a space without being visible as distinct clouds. Its purpose is to catch and reveal light beams, add depth between foreground and background elements, and create a subtle atmosphere that makes lighting look cinematic. Nearly every professionally shot film and television scene uses some level of haze — even scenes that are not supposed to look atmospheric.
The Look Solutions Unique is a dedicated haze machine that produces an exceptionally fine, even haze that hangs in the air for extended periods. Unlike fog machines that produce visible bursts of output, the Unique delivers a continuous, nearly invisible mist that gradually builds to the desired density. It is the preferred haze machine for cinematographers who want atmospheric depth without visible smoke effects.
Smoke
Smoke refers to the visible output that mimics combustion byproducts. On set, smoke effects range from the output of a standard fog machine used at high density to purpose-built smoke devices like Artem smoke canisters and coloured smoke grenades. Smoke effects are used for fire aftermath scenes, explosions, industrial environments, and any situation where visible combustion is part of the story.
Choosing the Right Machine
The right machine depends on the effect you need, the size of your space, whether you have access to power, and the level of control you require. Here is a breakdown of the professional machines we recommend for film and television production.
Look Solutions Viper NT
The Viper NT is the flagship fog machine from Look Solutions and the standard choice for professional film and television production. It delivers massive output with precise DMX control, fast heat-up, and the reliability that comes from German engineering. The Viper NT excels in large spaces, exterior scenes, and any situation where you need high-volume fog on demand.
Key features include variable output control, DMX compatibility, rapid recovery between bursts, and a robust build that handles the rigors of daily production use. The Viper NT is the machine you want when the script calls for dramatic fog effects and you cannot afford inconsistency or downtime.
Look Solutions Viper S
The Viper S is the compact sibling of the Viper NT, offering the same quality fog output in a smaller, more portable package. It is ideal for smaller sets, practical locations where space is limited, and productions that need professional-grade fog without the bulk and power requirements of the full-size Viper NT.
The Viper S is a favourite for commercial shoots, music videos, and indie productions that need professional results on a tighter budget. It delivers enough output for most interior scenes and medium-sized exterior setups while being easy to transport and quick to set up.
Look Solutions Power Tiny and Tiny CX
The Power Tiny and Tiny CX are battery-powered fog machines that solve one of the biggest challenges in location shooting: access to power. These compact, portable units run on rechargeable batteries, allowing you to place them anywhere on set without running cables or finding outlets.
The Tiny CX is the newer model with improved battery life and output consistency. Both units are perfect for run-and-gun shooting, documentary-style sequences, and tight practical locations where power access is limited. They produce enough output for close-up atmospheric work and small to medium interior spaces.
Look Solutions Unique (Haze)
The Unique is a purpose-built haze machine that produces the finest, most even atmospheric haze available. It uses a different technology than fog machines, creating an oil-based mist that hangs in the air for hours without settling or dissipating. The Unique is the preferred choice for cinematographers who want consistent atmospheric depth across an entire shooting day.
Unlike fog machines that produce visible bursts, the Unique builds haze gradually and maintains a consistent level once established. It is nearly silent during operation, produces no visible output stream, and requires minimal attention once set to the desired level.
Understanding Fog Fluids
Using the correct fluid in your fog machine is not optional. The wrong fluid can damage your machine, produce inconsistent results, and potentially create health and safety issues on set. Each Look Solutions machine is designed to work with specific fluids, and using the correct match ensures optimal performance and machine longevity.
Regular Fog Fluid
Regular Fog is the standard fluid for the Viper series and most general-purpose fog applications. It produces a medium-density fog with good hang time and natural dissipation. Regular fog is the starting point for most production scenarios and delivers reliable, consistent results.
Slow Fog Fluid
Slow Fog produces a denser fog that dissipates more slowly, staying low and lingering in the scene. It is ideal for low-lying fog effects, graveyard scenes, and any situation where you want the fog to build up and maintain density. Slow fog is thicker than regular and creates a more dramatic visual impact.
Quick Fog Fluid
Quick Fog dissipates rapidly, making it perfect for scenes where you need a burst of fog that clears quickly. It is useful for action sequences, transitions, and any scenario where you need atmospheric effect without persistent fog lingering in subsequent shots.
Cryo Fog Fluid
Cryo Fog is formulated for use with cryo cooling systems that chill the fog output, causing it to stay very low to the ground. This creates the classic low-lying fog effect seen in concert stages, horror films, and dream sequences. Cryo fog combined with a cooling system produces thick, ground-hugging fog that does not rise or fill the room.
Unique Haze Fluid
The Unique haze machine requires its own dedicated fluid formulated for its specific heating and dispersal system. Using fog fluid in a haze machine or vice versa will damage the equipment and produce poor results. Always use manufacturer-specified fluid for each machine type.
Tiny Fluid
The Power Tiny and Tiny CX battery-powered units use their own fluid formulation optimized for the smaller heating elements and lower power consumption of portable machines. Using standard fog fluid in a Tiny unit can clog the system and reduce battery life.
Smoke Distribution and Control
Smoke Distribution Tubes
Smoke distribution tubes are flexible ducting that attaches to the output of your fog machine, allowing you to direct fog to specific areas on set. They are essential for controlling where the fog goes, especially in tight spaces or when you need fog to enter the scene from a specific direction.
Distribution tubes are invaluable for pumping fog through doorways, windows, or vents to create the illusion of smoke entering from another room or outside. They also allow you to position your noisy fog machine farther from the set while delivering fog exactly where the camera needs it.
Artem Smoke Canisters
Artem smoke canisters are self-contained smoke devices that produce thick, realistic smoke without needing a fog machine or power source. They are ignited and produce a sustained plume of smoke for a specific duration, making them ideal for fire aftermath scenes, explosion effects, and any situation where you need localized smoke from a specific source point.
Artem canisters come in various sizes and durations, allowing you to match the smoke output to the needs of your scene. They are favoured by stunt coordinators and special effects teams for their reliability and consistent performance.
Coloured Smoke Effects
For scenes requiring coloured smoke, EG18 smoke grenades and EG25 smoke grenades produce vivid, dense coloured smoke in a wide range of colours. These professional-grade smoke devices are used in film, music videos, photography, and events where coloured atmosphere adds visual impact.
The EG18 is the standard size, producing approximately 90 seconds of dense coloured smoke. The EG25 is the larger format, delivering more output over a longer burn time. Both are available in colours including red, blue, green, yellow, orange, purple, pink, and white.
Fog Machine Maintenance and Repair
Professional fog machines are precision instruments that require proper maintenance to deliver consistent results. Neglecting maintenance leads to clogged heaters, inconsistent output, and ultimately costly repairs.
Use the right fluid. This is the single most important maintenance step. Using the manufacturer-specified fluid prevents buildup and clogging in the heating system. Never mix fluid brands or types.
Clean after every use. Run a cleaning solution through your machine after each production day. This prevents fluid residue from hardening in the heating element and pump system.
Store properly. Drain excess fluid before storing, keep the machine in a dry environment, and protect it from temperature extremes. Proper storage between productions dramatically extends machine life.
Regular service. Even with proper care, fog machines need periodic professional service. Heating elements, pumps, and seals wear over time and need replacement before they fail on set.
When your fog machine needs professional attention, SPFX Supply offers fog machine repair services as an authorized Look Solutions distributor. Our Toronto service centre uses OEM parts and has the expertise to diagnose and repair any Look Solutions machine.
Residue and Safety Considerations
All fog and haze products produce some degree of residue, and managing this is an important part of working with atmosphere effects on set. Water-based fog fluids produce a light moisture that can make floors slippery, so non-slip mats and warning signs should be placed around fog machine positions. Oil-based haze from the Unique can leave a light film on surfaces over extended use, so protect sensitive equipment and surfaces.
On the health and safety side, modern professional fog and haze fluids from manufacturers like Look Solutions are formulated to be safe for breathing in normal use concentrations. However, extended exposure to heavy fog can cause throat irritation in some individuals, so provide ventilation between takes when using heavy fog effects and keep fog density to the minimum needed for the desired visual result.
Always inform the cast and crew when fog or haze effects will be used, as some individuals may have respiratory sensitivities. Keep Safety Data Sheets for all fluids on set and follow any local regulations regarding atmospheric effects in enclosed spaces.
