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.
In contrast, photorealism in sculpture has no relation to photography. This is because sculpture is a three-dimensional art, whereas both painting and photography are two-dimensional. Superrealist sculptors therefore have the same problems of technique to overcome as Renaissance artists.orks by photorealist artists can be seen in several of the best art museums in America, including the Museum of Modern Art in New York.
