Why Color Temperature Matters in Photography
Understanding color temperatures is crucial for achieving accurate colors in photography. While Automatic White Balance (AWB) helps, manual settings often yield better results. Use this app to measure color temperatures and set your white balance accurately for stunning photos.

Accuracy
To ensure the best possible accuracy, this app uses a common white paper or a grey card to measure color temperature (CT, correlated color temperature, CCT). Just make sure the paper is lit by the light source you are measuring and avoid any color casts. While usually not necessary, calibration can further enhance accuracy.

Free for a Limited Time
Enjoy full functionality for a few weeks. After that, choose a one-time fee or subscription — still at a fraction of the cost of a dedicated device.

uninstalled in less than 5 minutes. not even close to accurate. I used a white piece of PVC ceiling tile on the floor and at varying heights and it reads twice what it should be reading for the color selected on the can lights on using. just visually I can tell the can light. this out reads it at 4400k from an 11-ft ceiling to the floor. the lifetime price wasn't bad but the app just doesn't work

Hi Truman, sorry to hear this. The calibration feature in Kelvin Meter is designed for this situation — sensor variance can affect readings. Happy to help from apps@contechity.com if you're willing to give it another shot!

The right color temperature is essential for ensure your plants growing inside get the right light for their needs. We start a lot of our garden plants inside a couple months before we can plant them outside here in West Michigan, and this app (along with the same developer's Lux Meter) help me give them the right light. Great app for a great price!

Was so helpful I just purchased it. I do echo the other reviews and suggestion to move the same button to more ergonomic location around square window. It would be nice to be able to grab the reading with one hand. But also with your left hand as the save button is on the right. Other than that this came in handy for my shoot. That I instantly bought it when we were done filming.
