11. ion LUNA STAR F was conceived for professional use Due to its swivel sensor swivel head the meter is easily adapted to universal service Incident light measurement leads to particularly precise exposures With incident light measurement the LUNA STAR F with adjusted diffuser is pointed from the subject towards the camera to measure the incident light to guarantee a precise exposure in conformity with the correct tonal values of the subject This is particularly important with inherently bright or dark subjects Even in difficult exposure situations for instance with contrasty subjects incident light measurement with the diffuser results in far more accurate exposures to satisfy the most discerning professional requirements Incident light measurement is also imperative with inaccessible subjects For this purpose it is necessary to select a point that has the same lighting level as the subject And then a meter reading is taken with the meter pointed at the same angle towards the camera as it would babe been from the subject This very convenient method of light metering at a point with the same lighting level is highly recommendable for outdoor shots The measurement is performed with a complete about turn in front of the camera so that the reading is taken with the meter pointing towards the camera 1 e opposite the actual picture shooting direction Incident light measurement i e with diffuser also gives a precise reading of the brightness c
