This problem was solved by Dolph in 1946. He derives a method for obtaining weights for uniformly spaced linear arrays steered to broadside (=90 degrees). This is a popular weighting method because the sidelobe level can be specified, and the minimum possible null-null beamwidth is obtained.
Some differences is that: Photography can form a picture in seconds, where as a painting can take months to create. Also, photography is a cheaper, and also, you can make sooo many images of the same photo via the negatives. Paintings have only One, unless the artist is bothered to paint the exact same painiting! lol.
Photography. 1  Body painting and photography are an inseparable pair due to the ephemeral nature of the body painting medium. Like a Tibetan sand mandala a body painting piece that may take up to 9 hours to create will inevitably be washed down the drain in seconds. During the Body Fine Art event a juried group of professional photographers will document our body painted models in various uniquely designed studio areas and their images will be submitted to the Body Fine Art Photography Competition.
