Professional light analysis without expensive hardware. Measure color temperature, inspect the visible spectrum, directly through your camera. With LightSpectrumPro EVO you can measure the color temperature of a light source without having to spend hundreds of dollars on professional devices. LightSpectrumPro EVO has an error of 2 - 8% compared to existing professional products on the market. in addition to the color temperature measurement in Kelvin, LightSpectrumPro EVO allows you to view the color spectrum of the light being examined with a band ranging from 360nm to 800nm. in addition to the spectrum it is possible to display the position of the white point on the CIE 1931 diagram and to apply a filter for wavelengths to display in overlay on the image captured by the cameras which elements reflect a specific frequency and with what intensity.

Super cool!

First, the fact that it does what normally takes thousands of dollars in tools is fantastic. No, it's probably not nearly as accurate as pro devices to do this work and having said that, since I don't have access to pro-grade tools I cannot say how the accuracy of this compares. But now I have a way to quantify the various values of light sources, and most helpfully, I can compare them objectively.This is certainly an app that every art, theatre lighting and photography student should own. Such a good learning tool to see how light sources and color interact.For homeowners this tool helps sort through the spec's of the multitude of light bulbs at the big box stores.I'm using this on an iPhone 6s with no problems.My only complaints:-The interface can get cluttered. Using it in landscape mode helps that quite a bit. In portrait mode, at least on my little phone, things get piled on each other. Wish it would run on my older iPad!-The helpful explanatory tips are good, but I wish I could figure out how to shut them off.-I wish I could take screen shots in landscape view.Wish:-Now if it had a way to measure flicker of bulbs! Don't care, make it a separate app or make it a purchasable upgrade for this one. I'd buy it!

Quite accurate!

I used to use a $2,000 light meter to measure color temperature when I worked in the film industry. This meter costs only a few bucks and is almost as good. The app description says it’s within 8% of the actual color temperature, which in most circumstances is sufficient. I tested the app in a variety of environments; I.e. outdoor sunny, outdoor cloudy, interior lights, balanced to daylight, cool white, etc. and it worked great. If you’re doing scientific measurements it might not be what you need but for film and video it’s pretty great.

Just got this app and held it under our Halogen and LED lights and our LED grow-light. This app is sensitive: the grow light has rows of different color LED and as I moved my iPhone the data changed with small moves. I think it will work great. And I love that there are no (that I’ve discovered) additional in-app purchases like so many apps have nowadays.

For photography white balance, I aim this at my light source, take a kelvin reading, enter it into my camera and viola!, perfect white balance, no need for cards nor discs…I photograph models and get them into magazines.
