Surprisingly accurate on my devices I tested this application against several known color temperature sources and it reported the color temperature/Kelvin within a very small variance to the expected number. Nexus 5 running stock Android 6.0.0 rooted it was consistently within +/-100K. Nexus 7 (2013) stock Android 6.0.0 rooted it was less accurate varying by +/-200K. Samsung S5 Android 5.1 consistent within +/-200K. Surprise results on Amazon Fire Phone FireOS 4.6.3 rooted varying +/-100K.
Can tell the Difference I just bought this and took photos using my Sony A35 with Minolta 50mm f2.8 prime lens comparing it to the Auto function and various other settings. Used f stop of 4 for all comparison photo's and then shutter speed to match f stop. Tried it out first just analyzing the subject. The color temperature was definitely off when compared to Auto. Second series I followed the instructions by taking a picture of white paper placed in front of the object first to analyze. The difference is between night and day. The photos I took using the Color temp settings looked like I had used fill flash. The colors were more true than using the Auto feature. It also brought out more detail than the auto function. I would post comparison photos but this does not let me. I would recommend this App, but if you plan to rely on it I would make sure you always carry a white piece of paper with you.
Pretty accurate, +-500°K and wide range I'm not sure if I was supposed to get a result over 1'000'000°K but I got a reading of 1'847'510°K in a room lighted with UV-A lights. It's pretty impressive considering that the result was confirmed by a cheap spectrometer.
Amazing. Simply amazing Comes in handy working as a cinematographer. May not always be 100% dead on, but the preset suggestion is always right so it will give you a starting point when something is wonky. Im suprised there arent more apps thay do this. Worth every penny.
BE CAREFULL This app on a galaxy note 2 doesn't work. everything is 2200 Kelvin off. Program needs a way to calibrate against whatever the phone or camera is doing. but I tested it against my REAL color spectrometer and it just failed horribly.
Need to be able to calibrate I downloaded this app and tested it in a television studio where the lighting was set to 2800k using a Sekonic C-500 color meter. The app was at least 1k cooler than the actual color temperature. If you just had a way to calibrate it, it may be of some use..... but currently it is useless.
