Light Diffuser

An important component of how a shot looks and feels to a viewer’s eye is the lighting. Specifically, the overall tone of a shot can be deeply affected by the quality of the light. The filmmakers have certain specific tools at their disposal like diffused light, hard light, and everything in between to tell a story through their shots. Here, in this blog, we will take a look at how diffused light photography is created with the help of a Light Diffusing Film. What a light diffuser actually is and what is its working mechanism? Let’s start.

What is a Light Diffuser?

Cinematographers and gaffers often make use of a Light Diffuser in order to create diffused light. To put it in a simpler way, it is a semi-transmittant piece of material that is placed between a light source and a subject for diffusing the light as it passes through the material. The Light Diffusing Film, used in these light diffusers, not only solely cuts or blocks light but also redirects light as it passes through for a diffused light spread on an object.

Uses of a Light Diffusing Film:

  • Creating Soft Shadows
  • Creating Soft Lighting
  • Less Contrast

Working Mechanism of a Light Diffuser

Before you understand what a light diffuser is, you need to understand how light actually travels. Light interacts with many particles on its path as it travels from its source through the air. The path of light is changed as its photons interact with more and more materials within its path. 

The more particles or material that a light source’s photons interact with before it reaches its subject. The more extensive the spread of light and photons is on a subject. This is what is known as diffused light. Diffused light is mainly used for less harsh shadows and soft lighting. It is often more blarneying on a subject. 

When you make use of a Light Diffusing Film, a light source will be redirected into a broader, more even spread resulting in softer shadows, less contrast, and an overall more flattering lighting style for a subject. 

Light Diffusers can either be a single sheet of diffusion placed on the barn doors of light or they can be large sheets of diffusion placed at a distance from a light. There are several ways through which you can introduce a diffuser into a lightning setup and that mainly depends on the lighting scheme you are trying to design. 

You should take note here that a Light Diffusing Film used in Light Diffusers can result in a loss of output of light. So, when you are on for creating diffused light with a diffuser, you should always opt for a stronger light source. 

Benefits of Light Boxes in Advertising

LED light boxes, whose chief component is Light Box Film, is widely recognized as one of the most effective medium of advertising. Unlike a non-illuminated poster or sign, corporate signage and promotional posters utilize a combination of color and illumination, which are far more likely to captivate a potential customer’s eye. 

Why use LED Light Boxes instead of Fluorescent Lighting?

(1) Lower Power Consumption: When compared to the fluorescent counterparts, the energy consumed by a LED is much less. They make use of only a fraction of the electricity required. To power fluorescent lights even during the production of stronger lighting. 

The size and shape of Fluorescent light drastically affect their energy efficiency. If you want a fluorescent light box to produce specific colors. Color filters are paramount which adds to the overall cost of installation. But for LED lights, having to concern varying degrees of power consumption depending on. The form factor of your lightbox the whole of. Which is made up of Light Box Film is never a matter of concern. 

(2) Longer Life Expectancy:

The longevity of LED lights is around 35.000 to 50,000 hours of use. Whereas, the average fluorescent light will only be of use for about 10,000 to 15,000 hours. Whereas fluorescent lights need to be constantly swapped out with new ones during their life span. LED lights reach the end of their lifespans without much maintenance required. 

The great durability of LED lights also extends to their shock resistance. Since the Light Box Film within the light boxes are generally placed in spaces where there are high chances that they can come in contact with people, you need to make sure that the Light Box Film can withstand the very real possibility of getting hit or bumped into. Unlike fluorescent lights which are relatively fragile, LED lights can absorb impacts.
