Description

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.

What’s New

Version 4.2.1

Added a new function that allows you to estimate the value of PAR (Photosynthetic Active Radiation) emitted by the light source. The value is expressed in PPFD (Photosynthetic Photonic Flux Density) in umol/m2/s, which consists of the quantity of PAR that reach the surface of the plant per second.
Fixed some UI bugs
Added compatibility with new devices
Minor bugs fixed

Misspellings

Some old-fashioned people think that a quality program should have no misspellings. So think about ‘cancel’ and ‘wavelength’, please. Aren’t you embarrassed by these errors?

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!

Camera issues on iPhone X!!

There’s a serious camera issue when opening up the app on the iPhone X on iOS 11.4.1. Video/picture feed is super fuzzy and not sharp at all!

Update: AUG 2020, 2 years later and the camera issue has NOT been fixed!! I’m now on an iPhone 11 Pro Max running iOS 13.6. This app is still having issues focusing both the rear and front facing cameras! Anything in front of it still remains unfocused!! There is still no tap to focus option! What a disappointment and waste of money!!
