Fog In A Can? Quick Answer

We are often asked what is the difference between these three special effects machines. So we thought we’d put this quick guide together to explain what the main differences are and what machine you should use to get the effect you want.

SMOKING MACHINE

Smoke machines, also known as smoke machines, use a special liquid to produce thick white smoke to create an impressive visual effect. They often come with a remote control to control the amount of smoke produced as well as the duration. Fog machines produce a similar effect to low fog machines, however, the heated smoke produced by fog machines rises and disperses throughout the room, while low fog machines produce cold liquid particles and the fog stays close to the ground.

Input: smoke liquid

Exit: smoke

Particles: smoke

Use smoke machines for: shows, concerts, parties, scary effects. Use it when you want the whole room to be smoky and not just the floor (low smoke machine).

LOW FOG MACHINE

A low-level fog machine (similar to dry ice machines) creates a dense, opaque fog that stays close to the ground to create a “walking-on-air” effect. Fog machines create this effect by cooling liquid onto liquid particles. A low fog machine will typically produce an intense burst of fog rather than a more subtle diffusion like a hazer. The effect of a low fogger is similar to that of a fog machine – both are designed to create a visual effect/impression, while a haze machine is designed to emphasize other effects such as beams of light or lasers.

There are two main types of low fog machines:

A dry ice machine – this uses solid dry ice and water. It’s a simpler method but doesn’t have the runtime of the cryogenic machine.

A cryogenic machine – this uses a liquid such as liquid CO2 gas and has a longer lasting effect.

Input: dry ice or liquid CO2 gas (depending on machine type)

Exit: low-lying fog

Particles: liquid droplets

Use low level smoke machine for: Weddings (especially for the first dance), shows, theaters, Halloween parties.

HAZE MACHINE

Haze machines, also known as “hazers”, can be oil or water based and are used to complement lighting effects. Haze machines produce a fine and subtle haze with long ‘hang time’ – the particles remain in the air for a long time before dissipating, making them ideal for use at shows and concerts. They produce a much more subtle and less noticeable effect than smoke or fog machines because they are designed to emphasize the lighting effects, allowing you to see rays and patterns that you would not normally see.

Input: fog liquid

Output: fine mist/haze

Particles: liquid droplets

Use haze machines for: shows, concerts, festivals and anywhere you want to emphasize lighting effects or create a foggy atmosphere. Perfect if you don’t want the thick, opaque effect of a smoke machine or smoke machine.

With each of these machines, there is a big difference between the cheaper versions and the professional machines. If you want quality, reliable performance at your event, go for the latter. This doesn’t necessarily mean you have to pay more, but you definitely get better value for your money. Professional machines usually have a continuous automatic cycle, which means they can work continuously without having to stop.

Dear Tom,

What is the difference between haze and fog?

Art glasses, Midlothian

love art,

This difference between haze and fog is their composition. Fog consists of tiny water droplets suspended in the air near the ground. Above ground, the same phenomenon is called clouds. Fog only occurs when the air is saturated or nearly so, meaning the relative humidity is at or near 100 percent. Haze consists of tiny particles of smoke, dust, salt, or other particles that may be airborne and not necessarily near the ground.

Fog is easily distinguished from haze. Fog is gray in color and noticeably moist. Haze produces a faint yellowish or brownish color when viewed against a bright background, or a faint bluish color when viewed against a distant dark background such as a mountain range.

Atmosphere Aerosol is a new aerosol spray for photographers and filmmakers that essentially serves as a fog machine that you can easily carry in your camera bag.

Do you need to add some haze or fog to your shoot to create a certain atmosphere or to capture sunbeams? Just shake the can, spray around and shoot.

The 8 oz. Cans are similar in volume to a can of hairspray and smaller than a typical 70-200mm lens, making them a portable alternative to heavy and expensive smoke machines.

It’s safe, non-toxic, and clear: ingredients include propane (45%), butane (45%), and mineral oil (10%).

“Hairspray cans, aerosol shaving cream cans, and other pressurized canned products like PAM cooking spray use propane and butane as propellants,” says Atmosphere Aerosol. “When Atmosphere Aerosol is sprayed, a small, non-harmful amount of gas drives the spray and quickly dissipates, leaving the mineral oil in the air.”

The spray stays in the air for minutes. A single can will spray continuously for about 5 minutes and 30 seconds. Since it is recommended to spray for at least 20 seconds, you can get around 15 uses from a single can before it’s gone.

Here’s a short video showing how to use the mist spray for a wedding portrait:

Here are a few sample photos created with Atmosphere Aerosol:

You can purchase Atmosphere Aerosol for $12 per can on the product’s website. There are also wholesale pricing if your studio needs more than 12 cans at a time.

With Atmosphere Aerosol, photographers and filmmakers can create fog or haze for photos and film quickly, easily and safely.

Shake can well before use. Spray in room or resting area for 20 seconds or more. Atmosphere Aerosol lingers in the air for photos and films for minutes.

VERY IMPORTANT! Backlighting is required to see haze or fog. The position and amount of light determine the appearance of the fog or haze. Spray again if necessary.

Shooting tips

Below are examples of using Atmosphere Aerosol for indoor and outdoor shots with natural and artificial light for photography and film.

shooting outdoors

For the shot below, it was a sunny day with very little wind, and it was morning. The trees and leaves helped Atmosphere Aerosol linger in the air. Spray Atmosphere Aerosol into the air behind the subject to disperse it evenly throughout the scene. When there’s a breeze, spray Atmosphere into the wind to disperse the haze as it moves upwind.

Indoor shots with natural light

The following shots were taken indoors with natural light streaming through the windows. The air was still, the windows were closed and we were nowhere near running fans or air conditioner vents. Something to watch out for when using Atmosphere Aerosol indoors with natural light is direct light hitting the wall or floor as in the image below.

Position your subject or subjects and spray Atmosphere Aerosol into the light. The position of the light and the amount of atmospheric aerosol used determine the appearance of the nebula.

Photographing with artificial light

You can create the illusion of the sun using a light source (such as a flashlight, flashlight, or video light).

Color gels can also add creativity to your photos. A full CTO has been used in the image below. The light was shot into the barn wall to cut and shape the light into rays.

Today we’re talking about an invention that has undoubtedly changed our lives: have you ever thought how many aerosol spray cans we have at home and how we use them on a daily basis?

A new article in the Dispotech Blog is online! Welcome back to our website, where we keep you up to date with interesting news, research and the latest products in the field of medical devices every week.

Today we’re talking about an invention that has undoubtedly changed our lives: have you ever thought how many aerosol spray cans we have at home and how we use them on a daily basis?

At Dispotech, your disposable excellence, we have made an aerosol spray product one of our best-selling and most appreciated items: Dispo Ice Spray is the ready-to-use spray ice perfect for athletes but also for minor bruises and domestic injuries.

But who invented aerosol sprays and how did this innovative product develop and how can we imagine everyday life without it?

The first experiments into the possibility of spraying a canned product were made by Norwegian chemical engineer Erik Rotheim, who designed the first can with a nozzle in the late 1920s. Rotheim called it an aerosol spray can, or a can that can spray products in the form of aerosols. In 1926 the engineer sold the patent to a US company for “only” $17,000 (no less than $520,000 today!) (the invention was approved for the market in 1931); and the rest is history.

Before a Norwegian came up with the idea, people had already thought of something similar no less than two centuries ago: The first rudimentary attempts at spraying technology apparently date back to 1790 in France.

Aerosol spray cans are now in use all over the world and can contain any product – from creams, oils, paints and personal care products to insect repellent and our Dispotech Ice Spray!

How an aerosol spray can works is as simple as it is ingenious: the can (made of aluminium, tin or tinplate) contains a liquid substance together with a pressurized gas (usually propane, butane or isobutane). Squeezing the nozzle cap converts the liquid into a gas which is propelled out of the can ready for use.

Do you know the history of the aerosol spray can? Are you curious or would you like information about our Dispo Ice Spray? Contact Dispotech, your disposable excellence team, we will be happy to answer your questions!

Many false alarms result from activities taking place near fire alarms, particularly smoke alarms. To avoid unwanted false alarms, consider the following common causes and solutions, and do something to prevent them in your premises.

1. Cooking fumes

Ensure cooking is only allowed in designated locations with appropriate recognition (usually heat). Proper use of extractor hoods and closing doors between designated cooking areas and detector heads can further prevent false alarms. Toasters are often a source of false alarms and careful consideration needs to be given to where they are used.

2. Steam (from shower rooms)

Provide adequate ventilation in the shower room and keep doors to outside rooms closed. Sometimes signage can help guests/employees; Understand the need to close doors and take steps to prevent excessive vapor build-up.

3. Steam (from industrial processes)

Ensure that a suitable type of detector is fitted; Consult a qualified alarm technician.

4. Smoking (cigarettes)

Smoking should only be allowed in designated places protected by appropriate detectors designed to be appropriate to the risk but not capable of being triggered by cigarette smoke. Smoking under smoke detectors triggers them!

5. Aerosol Sprays

Wherever possible, avoid using aerosols in the vicinity of fire detector heads, where this is unavoidable consider using alternative products. Products like deodorant and hairspray commonly set off smoke alarms.

6. Hot work/dusty work

Consider installing temporary covers on the detectors while the activity is in progress. Makeshift covers should only be fitted by authorized personnel and removed immediately after the activity is completed. Whilst the detectors are covered in this manner, staff (including contractors) working in the area should be instructed to activate a ‘broken glass’ alarm if they see a fire. Dust can also prevent detectors from working effectively in the future. It is important to plan all hot and dusty work carefully.

7. Accidental and/or malicious damage to a Break Glass point

Consider protecting vulnerable glass break detection points with approved covers or guards to prevent accidental damage. In some cases, the reporting point needs to be moved to a convenient location to reduce the likelihood of damage. CCTV for security purposes can deter malicious actions.

8. Inspection and Maintenance

If your system is monitored, before testing or maintenance begins, you must notify your alarm center that testing and maintenance is taking place and notify them when it is complete.

9. Changes in use or layout of the building

If changes are planned, the fire risk assessment should be reviewed to ensure that the fire detection system is appropriate for the use of the building.

10. Faulty detectors

Detectors can develop errors and this can lead to repeated inexplicable AFA trips. A competent person should check the fire alarm system and take any necessary remedial action, e.g. B. replacing the defective detector head.

11. Incorrect positioning of the detectors

Using the wrong detector can result in false alarms. When a detector is positioned too close to areas where environmental conditions may cause activation, consideration may need to be given to moving the detector. This work should be performed by a competent person. An example is where a smoke detector is fitted in a car garage where a heat detector may be more appropriate.

Some of the above solutions relate to the use of a building and can be solved by management actions alone. Others rely on changes to the fire alarm system.

Modifications to fire alarm systems should only be made by a competent person or contractor. Such changes should only be made after the fire risk assessment has been reviewed in the light of the problems or changes identified. All changes to the fire alarm system should be documented and the relevant certificate kept in your fire book.

Fire protection products and services should be fit for purpose and properly installed and maintained in accordance with the manufacturer’s instructions or a relevant standard. Third party certification schemes for fire protection products are an effective means of providing the best possible safety and providing a level of quality and reliability that non-certified products may lack.

Fog is a cloud touching the ground. Fog can be thin or thick, meaning people have trouble seeing through it. In some conditions, the fog can be thick enough to slow down passing cars. Even monuments like the London Bridge in London, England, or the Golden Gate Bridge in San Francisco, California are almost impossible to see in thick fog.

Fog is formed when water vapor or water condenses into a gaseous form. During condensation, water vapor molecules combine to form tiny liquid water droplets that hang in the air. Because of these tiny water droplets, you can see fog. Water vapor, a gas, is invisible.

Fog occurs when it is very, very humid. For fog to form, there must be a lot of water vapor in the air.

For fog to form, there must be dust or some type of air pollution in the air. Water vapor condenses around these microscopic solid particles. Sea fog, which appears near salty waters, is formed when water vapor condenses around pieces of salt.

Depending on the humidity and temperature, fog can form very suddenly and disappear just as quickly. This is called lightning fog.

Fog is not just fog. Fog is denser than haze. This means fog is more massive and thicker than haze. In a nebula there are more water molecules in the same area. Fog reduces visibility to one kilometer, meaning you cannot see further than one kilometer from your location. Fog can reduce visibility to a kilometer or two.

types of fog

There are several types of nebulae, including radiant nebulae, advection nebulae, valley nebulae, and freezing nebulae.

Radiation fog occurs in the evening when heat absorbed from the earth’s surface is radiated into the air during the day. When heat is transferred from the ground to the air, water droplets form. Sometimes the term “ground fog” is used to refer to radiative fog. Ground fog doesn’t reach as high as any of the clouds above us. It usually forms at night. Fog that is said to “burn off” in the morning sun is radiative fog.

Advection fog forms when warm, moist air flows over a cool surface. This process is called advection, a scientific name that describes the movement of fluid. In the atmosphere, the liquid is wind. When the moist, warm air meets the cooler surface air, water vapor condenses into fog. Advection fog occurs primarily where warm, tropical air meets cooler seawater. The Pacific coast of the United States from Washington to California is often covered in advection fog. The cold California Current, which runs along the west coast of North America, is much cooler than the warm air along the coast.

Valley fog forms in mountain valleys, mostly in winter. Valley mists form when mountains block dense air from escaping. The mist is trapped in the hollow of the valley. In 1930, steam condensed around air pollution particles in the Meuse Valley in Belgium. More than 60 people died as a result of this deadly valley fog.

Frozen fog is formed when the liquid fog droplets freeze into solid surfaces. Mountain peaks covered by clouds are often shrouded in icy mist. As the icy fog lifts, a layer of frost covers the ground, trees, and even objects like cobwebs. The white landscapes of freezing fog are common in places with cold, humid climates like Scandinavia or Antarctica.

fog catcher

Many ancient cultures collected water from fog by placing large pots under trees and shrubs. As the fog water collected on these objects, the pots collected the water. This method of collecting water was effective, but not as effective as collecting rainwater or other liquid water.

Today engineers are working on more sophisticated methods to collect water from fog. The most effective way was the development of “fog catchers”. Fogcatchers are very large screens built in dry areas. As mist slides in, water droplets form around the thin screens and drip into the collection basins below. A single strainer can collect over a hundred gallons of water in a day.

The village of Bellavista in Peru relies on fog collectors. Bellavista is an area that has little access to liquid water – no rivers, lakes or glaciers are nearby. Wells dry up quickly. Water for irrigation and human consumption is under threat. However, huge fogs blow from the Pacific Ocean every year. In 2006, the municipality invested in a series of fog collectors outside the city. Now Bellavista residents have enough water to irrigate trees and gardens, and to meet their own hydration and hygiene needs.

Engineers warn that fog catchers only work in small areas. Still, engineers and politicians are working on ways to make more powerful fog catchers that may reduce the need for humans to rely so heavily on groundwater.

For the past two mornings, Delmarva has had freezing fog, which is fog that is freezing on some surfaces. But on Delmarva we experience a variety of nebulae. In this blog post, we will examine five different types of fog.

Before we delve into the types of fog, let’s discuss what fog is. The official definition of fog, according to NOAA, is “water droplets suspended in the air at the Earth’s surface.” However, a simpler definition of fog is a type of cloud touching the ground. Fog forms when water vapor condenses to form these water droplets at or near the surface. This process is similar to cloud formation at higher altitudes. The different types of nebulae that we will discuss in this blog are: Radiation Nebulae, Advection Nebulae, Freeze Nebulae, Evaporation Nebulae and Mountain/Valley Nebulae.

Radiation Nebula

This type of fog is the most common in the country, especially in autumn and winter. It forms due to radiative cooling that occurs overnight under mostly clear skies as the air near the surface cools. Then, as the air cools further and reaches saturation, meaning the air contains the maximum amount of water vapor it can hold at a given temperature and barometric pressure, fog forms. As the surface cools further, the fog thickens. And as the air above that layer of fog cools, the fog deepens.

advection fog

Advection fog is similar to radiative fog in that it is formed by condensation. However, it does not occur due to radiative cooling. Instead, horizontal winds at the surface can lead to the formation of advection fog. This condensation occurs because warm, moist air moves over a cold surface—like warm air moving over ice. As this warmer air flows over the cold surface, the air is cooled to saturation; causing fog to form. Now, advection fog may look like radiative fog, but a couple of ways to tell the difference between the two is that this fog can form under cloudy skies and strong winds. Also, advection fog moves horizontally when horizontal winds move it.

Mountain/Valley Nebula

This is a kind of radiation nebula, but it’s a beautiful sight. At night, as the ground cools on the mountains, it sinks into the valleys. Here the cold air continues to fall, which lowers the ambient air temperature closer to the dew point temperature. This leads to saturation in the valley, which leads to fog formation if there is enough humidity in the area. This is common in the spring and fall months. And it’s at its densest during sunrise.

Freezing Mist

This type of fog presents a different type of hazard: ice conditions. Freezing fog forms in the same way as radiative fog, except now the air temperature is below freezing. Even when the air temperature is below freezing, the tiny water droplets can remain as a supercooled liquid until they come into contact with a surface where they can freeze. Once it freezes on a surface, it forms tiny ice crystals. Some surfaces where we commonly see these ice crystals are tree branches, sidewalks, and vehicles. Dangerously, however, these tiny super-chilled water droplets can freeze on roads, forming black ice that’s hard to see. Therefore, this type of fog creates dangerous driving conditions and drivers should drive slowly.

evaporation fog

In order for evaporation fog to form, warm air must be saturated through evaporation. Then this humid air mixes with cool, dry air to form fog. The best example of this is over a body of water. When cool, dry air moves over the warmer water, causing the warm, moist air over the body of water and the cooler air mass to mix. Then the humid air becomes saturated, resulting in evaporative fog. This type of evaporative fog is called a vapor fog.

Well, those are just a few types of fog. There are other types such as hail fog, which forms after a severe hailstorm, and super fog, which is formed when smoke from wildfires and water vapor condense to create this very dense fog type. Fog can drastically reduce visibility, so here are some driving tips if you encounter fog. If you encounter fog on your journey, slow down and put some more distance between you and the car in front of you. Never use your high beams when driving through fog as this will cause flare. You should use your low beams so your taillights are still on, or your fog lights. And if you know the area will be foggy before you leave home, set off a little early to allow for extra travel time.

Be safe when encountering fog and you can always tune into 47 ABC for your latest forecast.

Fog is an atmospheric condition characterized by the cloud appearing near or at the surface of the earth. Dew is the condensation that occurs due to temperature drops to the dew point. Calm winds cause dew to form. When the air above the ground cools with light wind speeds, fog also forms.
