Color spectrometers are a valuable tool to confirm the quality of the lights you use on your video and film sets. In this continuation of our Color Spectrometer series, we review the Asensetek Lighting Passport spectrometers, looking at its functionality, features, and how well it takes various measurements of light.
Color spectrometers are important for testing the color quality of lights used in your video and film projects. Many common color indices — such as CRI and TLCI — only tell a small fraction of a very large picture. Without fully looking at the color quality of your lights you may find out in post that you used a low quality light for your scenes, which ended up destroying the color in your image.
This article discusses how to use the average color spectrometer, what color characteristics to look out for, how to understand all the data and graphs, and how to take the spectrometer to the next level such as comparing light from a fixture before and after adding gels like CTO, minus green, and others.
In future articles we will look at specific spectrometers — such as Sekonic C700, UPRTek CV600, Asensetek Lighting Passport Essence Pro, and Asensetek Lighting Passport Standard Pro — along with their specific features and some of their limitations.
Bicolor LED lights sound like a great idea. However does mixing dissimilar lights result in high quality color across the entire range of color temperatures? Or will the entire range of light be sub-par from the manufacturer compromising the LED diode in order to make the two emitters mix?
We extensively tested a bicolor LED from a very well respected LED manufacturer to better understand the issues. We measured the CRI (Ra), CRI (Re), TLCI, CQS, TM-30-15, and color temperature to determine how the color quality stacked up across all levels of brightness (dimming) for the entire color temperature range.
The results are very … illuminating!
To get the most of our LED database of 165 LED lights, we explain how to read the color spectra and understand CRI (Ra), CRI (Re), TLCI, CQS, and TM-30-15.
When it comes to LEDs the majority of affordable options on the market do not produce great results. So we were a bit skeptical when we first heard of Aputure’s low cost LED lights. Our results: wow! In this video, we’ll share with you our real world experience with them and how they actually perform on-set.
Did you know that your old color meter no longer works with today’s LED lights? In this video, Ryan shows you why and what to do about it.
Did you know that LEDs lights may actually be ruining the look of your productions? And no, this problem can’t be fixed in the grade. We put seven different brands of LEDs lights to the test, capturing with a Red Epic Dragon camera. Then we discuss the results and how they’re going to affect the creative choices that you make on set.
