The Color Rendering Index can help you get the best LED color reproductions.Cover image via Shutterstock.The Color Rendering Index (CRI) is the go-to measure when speaking about the quality of different sources of light; the CRI rating can have a big effect on the reproduction of colors in your video shoot, so it’s important to keep in mind when selecting and using lights. However, do not confuse it with “color temperature,” which describes other aspects of light.What Is CRI?The CRI describes how accurately a light source reproduces colors on a scale from 1 to 100. The lower the number, the worse the reproduction of the color. Some spectrometers, such as the Sekonic C-700 or Gossen Mavospec, can read and display the CRI of a metered light source. That makes them brilliant tools for comparing different manufacturers and sources when working in videography and photography. However, these meters may be too expensive for many shooters, and while you can rent them, they aren’t a necessity on set. (Manufacturers will often list the CRI ratings of their lights on their websites.)As a general rule, any source with a CRI rating of 90 or above will faithfully render colors. Most good tungsten sources will have a CRI rating of 90 or above — often over 95. Sunlight will have the best CRI rating of all.The following is an example of the CRI rating of sunlight.Notice that the rating divides into eight different colors. This is a problem when using the CRI rating to analyze manufactured light sources — the sampling is only an average of eight colors. It is possible for a light to have a good CRI rating in regards to these eight colors, but it could still have a low rating beyond these color samples. It may not score highly for a deeply saturated red, for example, which would lower the rendering rating. Some LED lights can show large variations in different parts of the color spectrum when compared to tungsten or daylight; therefore, it is necessary to look beyond the standard eight colors when analyzing LEDs in particular.Beyond CRIThe Television Lighting Consistency Index (TLCI) is an improvement upon the CRI rating. It samples twenty-four colors, and it is more reliable for analyzing how light renders on a camera’s sensor. However, this index was initially for broadcast television cameras and arguably does not account for single-chipped cameras that are more common in the film and video industry.The Extended CRI rating (sometimes referred to as Special CRI) is the most useful for the majority of film and video applications. It is also what the Sekonic C-700 will display. The Extended CRI rating adds R9 – R15 colors to the standard CRI samples — including, most importantly, R9 Saturated Red, R13 Skin Color (Light), and R15 Skin Color (Medium), which are all difficult colors to faithfully reproduce.The image below shows an example of the Extended CRI rating of sunlightThis is as close as you are likely to get to a perfect CRI rating on a spectrometer on set. It shows that even sunlight is not getting a full 100 rating. This could be due to any number of reasons — even bounced light affecting the reading. However, it is a very good gauge of the reliability.Cheap LEDsIf we now look at a cheap LED, you will see a big difference.There are many areas of the color spectrum that this light will not render correctly. This would most likely result in odd hues in skin tones or other color casts within the image that are unexpected, undesired, and uncontrollable. However, the manufacturer could justifiably give this light source a CRI rating of 83. This is not an excellent rating but, at first glance, should at least imply a decent rendering of most colors. If this light source is priced well, it may be a viable alternative to more expensive options. Now the importance of the Extended CRI rating becomes more relevant. One can’t use sources such as this and expect faithful color reproduction across the spectrum. You would likely see similar inconsistencies with other cheap sources, most commonly with halogen and fluorescent lights.So, if you are looking to save money when renting or buying LEDs, halogens, or fluorescents, then always start by checking for an Extended CRI rating or a TLCI rating. If you can’t find one, consider renting a spectrometer and checking the rating yourself.Do you have tips for assessing lighting sources? Let us know in the comments.
The National Green Tribunal has directed the Uttarakhand and Uttar Pradesh Pollution Control Boards to display the water quality of the Ganga at all strategic locations on a monthly basis, to indicate whether the river water is fit for drinking and bathing.A Bench, headed by NGT Chairperson Justice Adarsh Kumar Goel, further pulled up the National Mission for Clean Ganga over its submission that the States of Bihar, Jharkhand, U.P. and West Bengal have not provided relevant information pertaining to the stretches between Kanpur to Buxar and Buxar to Ganga Sagar.“It has indicated that the States have not provided the information and therefore, action plans could not be formulated within the stipulated time frame. The lackadaisical approach of the NMCG can hardly be appreciated as it has been set up by the government with the sole object of rejuvenation of Ganga…,” the Bench said.It added, “We may have to take coercive action, including environment compensation being required to be paid by the NMCG, and U.P., Bihar, Jharkhand and West Bengal for not responding and failing to formulate the action plans for Phase II and Phase III.”The green panel has granted NMCG and the respective States a “final opportunity” to file action plans by April 30, pertaining to sewage treatment and utilisation of the same.The Uttar Pradesh government has also been directed to ensure that a committee headed by Justice Arun Tandon is consulted pertaining to waste management following the Kumbh mela in Prayagraj (Allahabad).
