Lumev

Lumev is a focused smart light meter for film photography. It turns the iPhone camera into a clear path from reading a scene to setting the shutter speed and aperture on a real camera. It is approachable for a first roll of film and precise enough for an experienced photographer.

MEASURE WHAT MATTERS

Begin with a full-scene reading. When the light is complex, open the live spot view, use digital zoom, and measure a face, subject, shadow, highlight, or any other important area. Every spot keeps its own reference image. Adjust the intended brightness for each reading, make one point primary, or give several points different weights. Lumev then shows the range of the scene instead of hiding it inside a single unexplained average.

EXPOSURE PAIRS YOUR GEAR CAN ACTUALLY USE

Create reusable kits with your camera, lens, film, working EI, and optional filter. Lumev respects the shutter speeds available on the camera, the aperture range and step of the lens, the selected focal length, and the light loss of a filter. It presents several useful shutter-and-aperture combinations at once, including a balanced choice, more depth of field, and a faster shutter. A clearly labeled chart and full table are there whenever you want to inspect every option.

UNDERSTAND EVERY RECOMMENDATION

Raw EV, your creative intent, filter compensation, and learned correction remain separate and visible. The “Why this exposure?” view explains how the final value was formed, so beginners can learn and experienced photographers can stay in control.

LEARN FROM THE DEVELOPED RESULT

Save each metering session with its scene image, individual spot frames, recommendation, and the settings actually used on the camera. After development, compare the result with the saved reference and rate the exposure. Lumev learns conservatively from repeated, consistent feedback for your equipment and preferences. One unusual frame will not suddenly change the model, and past readings are never rewritten.
