Lumu - bringing Light Meter to the 21st Century by Lumu Labs - Kickstarter


Lumu is a product made with more creative photographer.


The size of Lumu is small, and even if it is attached to iPhone it does not feel uncomfortable there. There is a gap of 2.2 mm between the attached Lumu and the iPhone. Also, since power is supplied from the iPhone, charging and charging batteries are unnecessary.


Looking at the existing exposure meter and Lumu (right end) side by side, the difference in size is obvious at a glance.


The back is made of metal and the letters of Lumu are engraved.


How to use Lumu is simple, when Lumu is plugged into iPhone, the application recognizes Lumu.


Then enter ISO and aperture and tap "SET" in the middle of the screen to calculate the optimum shutter speed for the shooting location.


Apart from measuring the exposure value, Lumu's application also has a function to store shooting location, measured values, notes, photos, etc. in cloud storage.


The exposure meter is equipped with a "Reflected light formula"And measures the amount of light hitting the subject"Incident light formula"Lumu adopts the latter type of incident light formula, so it is possible to measure the light intensity more accurately than reflected light formula.


Even when you wonder whether to set the shutter speed to 1/500 or 1/200 when shooting at the beach, you can measure the proper shutter speed with a single shot using Lumu.


Lumu can be used without problem even indoors.


Since the sensor installed in Lumu has higher performance than the existing exposure meter and iPhone's exposure meter application, the shooting location is too dark or it is too bright to measure the exposure value.


While Lumu is seeking investment for commercialization, it has already gathered about 80,000 dollars (about 7.6 million yen) far exceeding the target amount of 20,000 dollars (about 1.9 million yen), and commercialization It is almost fixed.
