Lumu uses the dome side as an incident light meter. It can measure Ambient or Flash Exposure of light on your subject. Use a single reading, or increase its accuracy by using Multi mode and let Lumu calculate the average of multiple readings. Pinhole mode is a great partner in crime for users who use analog cameras.

Lumu Photo Flash helps you increase the quality, not the quantity of light. Measure with it to get perfect exposure when using strobes or HSS flashes. Additionally, you can control how much Ambient vs. Flash light falls to your subject, measured in percentage. Precise calculation of Flash duration will also help you in freezing fast motion.

When measuring ambiental light in an architectural space, designing lighting fixtures, setting a scene, supervising stage lighting - a chromaticity meter just might be your best friend. A best friend you can fit in your pocket. Lumu Chromaticity allows you to see light in CIE 1931 color space. It calculates the Duv, CCT and Illuminance value in Lux or Foot-candles.

Lumu Flash Color simplifies the photographers workflow. Easily measure your flash white balance. Simultaneously measure color temperatures of both your flash and ambient light. If additional color filters are needed to achieve even results, Lumu lets you know which one (or two) to apply. All with a tap of a button.

When working on motion pictures, Lumu allows you to dedicate the most  time to your story subject. Using Cine/Video you can match your artistic vision with the footage you produce. Simply input your parameters and let Lumu measure the correct aperture of your picture.
