Holography still stays a laboratory process performed in a deep darkness. However dark rooms and the need to perform multiple operations in deep darkness seem to belong rather to 19th century than to current sophisticated data processing techniques facing 21st century. The possibility to obtain holograms and HOEs practically in any brightly lighted environment avoiding dark rooms is demonstrated. Ultra high resolution holographic media and the technique of momental holography well compatible with lighted environment are used for this purpose. Examples of HOEs, holograms and holographic interferograms made in presence of strong polychromatic light are presented. High quality holographic reconstructions from holograms obtained in diffused daylight as well as in strong sunny illumination of tens of klx are shown. He-Ne, Ne:YAG laser sources and ultra high resolution Russian holographic media PFG-03 or PFG-03C (color) were used in this work.
