Leave a Review Light Spectrometer Wavelength
Terrible
I got it and it said anything from purple to green was the same color. If I shined a light to get difference, it wouldn’t work.Test on TV monitor
Was detecting all the colors on screenWhite saturation calibration
This app works well when directed to block colours, but I have failed to get it calibrated with the initial ‘white’ surface to get it going correctly.
I tried pointing my phone camera at a sheet of white paper, a white wall both inside and also outside in natural light, but I still get the very same message on the screen that saturation is low and so accuracy will be low.
I found that disappointing.Show lessDeveloper Response
Thanks for your review! Dominant wavelength is a mostly meaningful to measure for colored light. If you want to measure natural light or any white or whiteish light, to see its Kelvin temperature (i.e. if it is cold or warm white) please instead use the White Balance Kelvin Meter app. Also, feel free to contact me directly, apps@contechity.com Thanks a lot!
