TURN YOUR I PHONE I NTO A PRO- GRADE LIGHT METER

When I decided to become a good photographer, the hardest part, after accepting the cost of truly good lenses, has been measuring light. My full-sensor digital-camera body and 55 mm ƒ/1.2 prime lens get adequate exposures on the dreariest days with the automatic settings. But those ‘average’ a picture to mediocrity: Everything is in focus, but nothing stands out. You need a light meter to measure the layering of light. That way, for example, you can add your own backlighting for a more dramatic effect. Decent light meters cost upward of R6 800 and often don’t measure colour temperature, the way a colour looks based on the light. The Lumu Power (±R4 100), however, plugs into any IOS 8+ device to measure flash, ambient exposure, and colour temperature, and determines ideal flash exposure. Just select two of the three critical values (shutter speed, ISO, or aperture) and pop your flash. – Dan Dubno
