If there’s one camera assistant you’d want for your iPhones, it’s bound to be this Lumu Light Meter. When attached to your iPhones, Lumu helps in gaging the settings available for your iPhone camera while you set forth on your photographic missions. The meter measures the light and the corresponding Lumu app calculates the photo parameters for you. Be it the ISO, aperture or time, Lumu measures it all and gives you the necessary details for taking that best picture. It’s time that you finally set forth on a photographic venture with just your iPhones paired with Lumu instead of your high-end cameras. That’s because now there’s an ultimate light measurer for your iPhones too.
