There are several great iPhone apps and attachments that turn the device into a light meter, including a previous entry from Lumu. But the company’s latest product takes metering to the next level by adding color to the equation.
Announced on Kickstarter earlier this week (and already having surpassed its funding goal several times over), the new Lumu Power is an attachment for your iPhone that turns the device into a fully functioning light and color meter. Unlike the original Lumu, which only had one sensor for measuring luminance values, the new Lumu Power has two sensors, one for luminance and one for accurate color temperature calculations.
Here’s their Kickstarter video:
And here’s a quick making-of video that details the process behind making the Lumu Power’s new color sensor as accurate as it can be.
