The light that comes from behind you can bounce off the inside of your shades and reflect back into your eyes. This is why all of our Optic Nerve polarized lenses have an anti-reflective coating on the interior lens surface to eliminate this effect.

Interchangeable lenses are the tried and true solution for battling inconsistent light conditions. Smoke lenses are best for bright sun conditions, while copper lenses are best for cloudy conditions, and clear lenses are optimal for very dark/nighttime conditions.

We all know the hassles of constantly changing light conditions whether on the trail or in the car. The photochromatic technology automatically darkens the lenses in sunny conditions and lightens them in shadowed or cloudy conditions in a matter of seconds. So how exactly does this happen? Photochromatic lenses are made up of trillions of organic molecules that rapidly change in structure in the presence of UV light. In bright sunlight, the molecules expand in size, darkening the lenses while in low light conditions the molecules shrink allowing more light to filter through.

Lighting is one of the most important aspects of TV production, as it can influence the mood, tone, and visual quality of a scene. By adjusting the lighting ratio and contrast, you can create different effects and emotions in your TV scenes, from drama and suspense to comedy and romance. In this article, you will learn how to use these two lighting concepts and some practical tips to achieve your desired results.

To adjust the lighting ratio and contrast in your TV scenes, you need to have some basic equipment and skills. To begin, you should have at least two light sources: a key light and a fill light. You can also add more lights, such as a backlight, a kicker, or a hair light, to enhance the effect. Position your lights according to the angle, distance, and direction that suit your scene. Use a light meter or a waveform monitor to measure the intensity of your lights and adjust them accordingly. Control the quality and color of your lights by using modifiers such as diffusers, reflectors, gels, or filters. These can help you soften, bounce, change, or filter the light to create different effects. Finally, check the exposure and white balance of your camera to make sure that your scene is properly exposed and color balanced. Tools such as a histogram, a zebra pattern, or a color chart can help you with this.

Lighting ratio is the relationship between the intensity of the key light and the fill light in a scene. The key light is the main source of illumination, usually placed at an angle to the subject, while the fill light is a secondary source that fills in the shadows created by the key light. The lighting ratio is expressed as a number, such as 2:1, 4:1, or 8:1, which means that the key light is twice, four times, or eight times brighter than the fill light, respectively.

Contrast is the difference between the brightest and the darkest areas in a scene. It is affected by the lighting ratio, but also by other factors, such as the exposure, the color temperature, and the reflectivity of the objects and surfaces in the scene. Contrast can be measured by a tool called a waveform monitor, which displays the luminance levels of each pixel in a scene. A high contrast scene has a wide range of luminance values, while a low contrast scene has a narrow range.

To evaluate the lighting quality of your TV scenes, you should consider criteria such as consistency and continuity, creativity and originality, as well as technical and artistic aspects. Your lighting should match the time of day, location, and mood of the scene and should not change abruptly between shots or scenes. Additionally, your lighting should support and enhance the story, characters, and emotions of your scene without distracting or confusing viewers. Furthermore, the lighting should be executed without errors or flaws such as overexposure, underexposure, glare, flicker, or color cast.

All Optic Nerve polarized and premium interchangeable models include a micro-thin hydrophobic coating on the outside of the lens that repels water, dust, sweat, and oil to significantly enhance overall performance and durability and to make lens cleaning more efficient.

Our lens venting systems on select performance styles allow air flow directly into the area behind the lens. This allows the air to circulate between the eye and the back of the lens which helps reduce fogging.

The choice of lighting ratio and contrast in TV scenes depends on the genre, style, and mood. Generally, a high lighting ratio and high contrast create a dramatic effect, while a low lighting ratio and low contrast create a soft and natural effect. For example, when creating a horror or thriller scene, you can use a high lighting ratio (8:1 or higher) and high contrast to create strong shadows and dark areas. For comedy or sitcom scenes, you can use a low lighting ratio (2:1 or lower) and low contrast to create bright illumination with minimal shadows. When creating romance or drama scenes, you can use a medium lighting ratio (4:1 or 6:1) and medium contrast to create a balanced and realistic illumination with some shadows and highlights. Additionally, you can use backlighting, front lighting, or side lighting to add further effects.
