The method for estimating the illuminance distribution in the vertical plane of museum objects (paintings) using a digital imaging luminance meters (ILMD) is considered. In order to pass from the luminance distribution to the illuminance distribution, a screen with reflective properties close to diffuse (Lambert) reflection is used. The theoretical and experimental uncertainty estimation of the measurement method done.
