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

Product Information

In some cases matching your artificial lighting to the ambient lighting can make an image weaker rather than stronger. If you're photographing a portrait under cloud or in the shade, technically you would add a light blue to your flash to match the color temperature of the ambient lighting. If you're photographing with an older flash, it may only go down to 1/16th power, which can be too much. (Most modern flashes go down to 1/128 power). One of the most common and easy situations where a gel can improve your photos is lighting on a cloudy day or in the deep shade. The white balance of a cloudy day is very different than that of a flash, which is balanced for daylight.

Your Budget Scale The Gels You Should Have No Matter Your Budget Scale

When shooting with flash in the shade or an overcast day, set your camera to the appropriate setting for the ambient lighting - in this case, dial your camera’s white balance to approximately 6800K to match the ambient light. CTB Flash gels are thin pieces of colored plastic that you can place over your flashgun, studio strobe, or any other artificial light source to modify the color of the light. (Actually they don't always have to be colored - we'll look at some neutral flash gels at the end of the article). Why bother adding a gelled softbox to colour the shadow gradient, when you could just as easily use a pink and blue gradient gel on the optical snoot instead?’

What Are Color Gels?

Some professional cameras designed for electronic news gathering use filter wheels containing color-correction filters and are designed to optimize performance for different color temperatures.

Great article! The way you presented Flash Gels and even more importantly demonstrated by example, with explanation was really appreciated! A ½ CTB gel should be the appropriate correction for the difference between daylight and deep overcast or deep shadow. If it’s a cloudy day with partial sun breaking through or you are only in light shadows, you may only need ¼ CTB. Gels and Golden Hour I believe what the OP is looking for is natural colored flesh tones. With the CTO filter over the flash, set the camera to tungsten WB and take a test shot. This should give close to normal skin tones. Try the same with the CTS filter, same camera setting. See which one you like better. The White Paper" (PDF). www.etconsult.com.

Using Color Gels on a Fill Light

In Shakespearean-era theater, red wine was used in a glass container as a light filter. In later days, colored water or silk was used to filter light in the theater. Later, a gelatin base became the material of choice. Gelatin gel was available at least until 1979. The name gel has continued to be used to the present day. Gelatin-based color media had no melting point, and the color was cast in the media as opposed to being coated on the surface, both important properties for color media. It would, however, char at high temperatures and become brittle once heated, so it was impossible to handle once used in the lighting instrument. Exactly. I have a CTO gels and use them, often with a tungsten WB, to blend the flash and ambient. Other times I may use a 1/4 CTO in daylight to warm up the skin tones slightly.

CTS is Color Temperature Straw - same idea as CTO, but more yellow (and less red). It's a very similar colour temperature shift - CTS is +160 mireds and CTO +167 mireds according to the Rosco Cinegel swatch booklet (CTO is 3407, CTS is 3441). Place two lights either side of the white sheet and point them up towards the low ceiling above. These two lights should have open dish reflectors attached to them so that we can spread the light over the ceiling as much as possible. You may be wondering why you would want to use an ND gel with your flash. Why not just turn the power on the flash down instead if it's too bright? Well, there can be instances where the flash is too bright even at minimum power. This is where an ND gel can come in handy. I shot these images on a 105mm prime at f2. The shutter speed was my usual 1/125th and the ISO was set to the Nikon D850 lowest setting at ISO 30. Color gels are essentially pieces of thin semi-transparent plastic (generally polycarbonate, polyester, or some other heat-resistant type) that change the color of your light.All three of these shots are perfect. Each one accomplishes a different goal. You can get the first shot without a gel at all. But having a set of CTB and a CTO gels gives you the freedom to alter the mood of the shot to intensify the cold,or neutralize the colors. As long as you understand the principles of the color of light and you have the tools, you can get exactly what you want, whenever you want it. 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. Viper_'Magenta'_Filter". www.cinematography.net. Archived from the original on 9 December 2006 . Retrieved 12 January 2022.
