Get Luminance

Get Luminance is a diagnostic empirical tool to measure and compare luminance as ‘seen’ incl textured, uneven, translucent, fluorescent & gloss surfaces; glare & shadows.

Get Luminance has been developed from research and provides an empirical basis for calculating luminance 'seen' by a photograph. The aim is to: • Provide and maintain good luminance contrast to create environments that are easier and safer to use by everyone. • Provide a cost effective and easy-to-use tool. • Facilitate compliance assessment in buildings and the public realm. • Assist designers identify compliant designs during the design process. • Support asset management and maintenance of existing assets. • Demystify luminance contrast and make it a mainstream concern.

Get Luminance includes the 4 main calculation methods used worldwide: Simple difference ; Bowman Sapolinski: Michelson: proportional difference.

Get Luminance measures what is ‘seen’ by the photograph and reflects the conditions experienced by users. It measures luminance in the prevailing light, (rather than the pure colour with a controlled light source - the basis of most colorimeters).

Who should use this App? Anyone concerned with safety and amenity in the built environment, such as building inspectors, certifiers, building control, access consultants, architects, designers, contractors, facilities managers, asset managers, disability groups, clients (building owners/tenants/employers etc), you and me.
