CTO (Color Temperature Orange) Warming Gel Filter Selection Kit 8 x 8 Inches

Product Information

This article is about color correction using lighting and camera filters. For video color correction in post-production, see Color grading. For color correction of still images in post-production, see Color balance. For mutual color correction of digital images, see Color mapping. Lighting scenarios throughout the day will include a church ceremony in a reasonably lit church in which no flash is allowed. Formals will be shot outdoors in both sunlight and shade at around 3 pm. The reception will be held in the evening in a hotel banquet room that is lit by incandescent tungsten lights which will be progressively dimmed as the evening progresses. The banquet room has 12 ft ceilings and walls that are an off-white color.

A color gel or color filter ( Commonwealth spelling: colour gel or colour filter), also known as lighting gel or simply gel, is a transparent colored material that is used in theater, event production, photography, videography and cinematography to color light and for color correction. [1] Modern gels are thin sheets of polycarbonate, polyester or other heat-resistant plastics, [2] placed in front of a lighting fixture in the path of the beam. If your entire scene is illuminated by flash, or you are shooting flash mixed with midday daylight on a sunny day, then you are shooting in an accurate way. The actual range of daylight white balances in ambient light is between 5000K-6500K. Match Camera WB to AmbientThe color of each flash will vary slightly depending on quality and consistency but is generally very very close to daylight which is 5500K.. Your camera’s flash or strobe white balance icon in your menu generally looks like a flash or lightning bolt. The first step to shooting with flash should be to set your white balance to that setting.

Accurate white balance depends on the color temperature of the scene. To have technically correct white balance, the color white is represented as perfectly white in your image. This is part of why many photographers take a photo of a grey or white card as a reference to later use to adjust the raw image for white balance later. Many also may just shoot on AWB. As well as correcting flash to match ambient light, color gels can be used to purposefully color the light a completely different color. This can be done in combination with ambient light, or using flash alone.

Using Color Gels for Background Gradients

When using flash it becomes important to choose your own white balance because the white balance of the flash may not match the white balance of the ambient scene. The white balance not only changes throughout the day as the sun goes from the horizon to the center of the sky, but you will also find different white balance on a cloudy day or in deep shadow or shadows.

How to Use CTO and CTB Gels to Change the Color of Your

Work with the subject and guide the pose - Nearly every half-decent lighting setup requires your subject to work their pose with the lighting. Having your subjects chin-up and allowing that soft light to fall on their face will often produce great results with this setup. Similar colors may vary between different companies' formulations – for example, many have a color named " bastard amber", but the transmitted color spectrum may be different. For this reason it is often misleading to refer to gel colors by name. Even a familiar color name, like Steel Blue, transmits widely differing colored light in each manufacturer's line. The optical snoot has a very specific quality to it thanks to its ability to create incredibly hard light resulting in the modifier producing very strong shadows and highlights. Its other core feature is that it can shine very defined highlight and shadow shapes thanks to its focusing lens at the front. The shapes that it shines are often referred to as gobos and they are metal disks with patterns cut into them that sit in the modifier itself. You don’t have to use the gobos though and I often just use the optical snoot as a very hard light source and that’s what I’ll be doing again here in the following lighting setup. Gelled Colour Gradients The 3rd light source had no gel and was used with a square 70cm softbox and a reflector just under the model to soften the shadows.As I mentioned above, if we place gobos into the modifier itself, we can focus the shadowy shapes with razor sharp edges thanks to the lens on the end of the modifier. However, if we place something in front of the optical snoot and not inside it, the resulting shape will be very blurred and out of focus. It’s this feature that we’ll be using to our advantage in this setup.

Teach yourself flash: Color temperature gels | TechRadar

Let’s begin by identifying the color of your flash. Your flash is the same color as full daylight, so if you took a photograph at mid day, in full sun and set your white balance to daylight and added a flash into the image, you would end up with completely matching color. This is your starting point. Full sun is a slightly blue light source and so is your flash. They both sit on the scale at 5500 K.It is common for a gel manufacturer to publish the transmission coefficient or even the spectral transmittance curve in the swatch book and catalogs. A low transmittance gel will produce relatively little light on stage, but will cast a much more vivid color than a high transmission gel, because the colorfulness of a light source is directly related to narrowness of its spectral linewidth. Conversely, the flatter its curve becomes, the closer the gel is to a neutral density filter. Photographing a subject in a dimly lit area where you want to use a very shallow depth of field (large aperture). The reason they are known as gels is because they were originally made from gelatin. Plastic is a lot more long lasting, cheaper, and easier to use, so you're unlikely to find any flash gels still made from actual gelatin today. In this article we'll look at how you can use flash gels for balancing flash with ambient light, creative use of gels for colored lighting effects, how they can be used for reducing the light power, and creating softer lighting.
