LightSpectrum Pro

Whatever the programming is doing is bad. It takes over the iPhone. I can’t even exit the program, buttons don’t response.

Works great for my realestate video & photo!

I bought this app with high hopes, but was prepared for some inaccuracies. That being said, I can’t any consistent or accurate readings. I am using a light source that I can control the colour temperature of, in a controlled environment, and comparing with readings from other meters / software. I feel this could be easily solved with some sort of calibration function, which I can not seem to find.

I downloaded this after seeing it spoken about on YouTube, and I thought I would give it a try. I downloaded it first to my iPad. The first time I opened it, the screen kept “blinking”, and nothing changed with the onscreen measurement, even though I tried a couple of different lighting conditions. I exited the program, and closed it. I opened it again. Voilà! This time, the blinking stopped and the measurement changed as it should. To test it, I set the Kelvin indicated on my Nikon Z6, and I am pleased with the result. I then tried it on my iPhone 6 Plus. The same blinking issue occurred the first time I opened the app. I closed and exited the app. I opened it again, and it seems to be working. I also compared the results using Auto WB on my camera, and there wasn’t that much of a difference, but there was a bit of a shift in the green channel. I may do a few more tests, and will share that if I get around to it. The program only works in portrait (vertical?) orientation. I gave the program 4 stars because of the first time start up bug, and because it does not change orientation.

Checked CCT against our Pro Lab equipment. NOT EVEN CLOSE. out by more than 1000K.

Shows overcast daylight as 2800K. I know it is 6000K, and my PDW700 agrees with me. Same price as two Mars bars so who cares. I deleted it.

The interface doesn't fit on my 6s so I can't even begin to try to figure it out. Waste of money.

App doesn't open on my 5S.... Just a black screen. I guess it's accurate in the dark. Developer says there's a fix coming in November, but WHY is this app for sale when it's unusable for many users??

Not working on new iPad 3 even if they say that it is compatible with iPad! Disaponited that I ve paid for this ,

This is a useless app. Don't buy it. It is nothing more than a random number generator.
