Access to a good light meter can make or a break a photo, but the designs are often bulky, archaic in user-friendliness, and expensive. The Lumu light meter is reduced to the size of the round sensor, eliminating the need for a separate handheld device. Instead, it works with your smartphone using a dedicated app for taking luminance measurements with a spectral response sensor that works like the human eye. Why not, since you already have your phone with you?!
