Don’t stop at metering. Lock the scene, arrange Key, Fill, Rim, and Background lights on a 2D canvas, then save the complete lighting recipe.
Light shapes every image.
Lumarix is a photography lighting assistant designed to help photographers and creators understand, measure, and work with light using their iPhone.
From ambient light measurement to exposure guidance and lighting analysis, Lumarix turns complex lighting information into clear, practical references you can use while shooting.
Measure Ambient Light
Use your iPhone camera to analyze the current lighting environment.
Lumarix provides useful lighting references including:
• Estimated EV
• Estimated color temperature (CCT)
• Tint
• Highlight condition
• Shadow condition
• Tonal contrast
• Subject and background brightness relationship
Understand Tonal Balance
Light is more than a single exposure value.
Lumarix helps you understand the relationship between highlights, shadows, subjects, and backgrounds so you can make more informed lighting decisions before taking the shot.
Spot Measurement
Select specific areas of your scene to evaluate light locally.
Compare your subject with the background and better understand how brightness changes across the frame.
Exposure Guidance
Turn lighting measurements into practical camera settings.
Lumarix can provide exposure references for:
• Shutter speed
• Aperture
• ISO
Helping you move from measuring light to making a shooting decision.
Lighting Assistance
Lumarix is designed around a complete lighting workflow — not just displaying numbers.
Measure the light around you, understand the result, and use that information to create a more intentional lighting setup.
On supported workflows, your iPhone display can also be used as a portable fill-light source for close-range photography and creative lighting experiments.
Made for Photographers and Creators
Lumarix is useful for:
• Portrait photography
• Product photography
• Food photography
• Macro photography
• Tabletop photography
• Studio work
• Video creators
• Lighting experiments
Whether you are working in a studio, at home, or on location, Lumarix gives you a fast way to understand the light before you shoot.
A Practical Lighting Reference
Lumarix uses iPhone camera data and image analysis to estimate lighting conditions.
Measurements such as EV, color temperature, tint, contrast, and lighting contribution are intended as practical photographic references and are not a replacement for dedicated professional light or color meters.
