This compensates for the fact that the recording time, which is in the order of a microsecond, continues to be very long in comparison with the processing time of an digital computer. The optical processing performed by a dynamic hologram is also a lot much less versatile than digital processing. On one facet, one has to carry out the operation at all times on the entire image, and on the opposite side, the operation a hologram can carry out is principally both a multiplication or a phase conjugation. In optics, addition and Fourier transform are already simply carried out in linear materials, the latter simply by a lens.

In Great Britain, Margaret Benyon began utilizing holography as a creative medium in the late Nineteen Sixties and had a solo exhibition at the University of Nottingham artwork gallery in 1969. This was adopted in 1970 by a solo show on the Lisson Gallery in London, which was billed as the 'first London expo of holograms and stereoscopic paintings'.

Since every point in the object illuminates all of the hologram, the whole object could be reconstructed from a small a part of the hologram. Thus, a hologram may be damaged up into small pieces and every one will enable the entire of the unique object to be imaged.

This enables some purposes, similar to a tool that compares images in an optical means. While this strategy to information storage can't attain the excessive knowledge rates of page-based mostly storage, the tolerances, technological hurdles, and value of manufacturing a business product are considerably decrease. A small however active group of artists still integrate holographic parts into their work. Some are related to novel holographic methods; for example, artist Matt Brand employed computational mirror design to get rid of picture distortion from specular holography. Salvador Dalí claimed to have been the first to make use of holography artistically.

One does, nevertheless, lose data and the spatial decision gets worse as the dimensions of the hologram is decreased – the picture turns into 'fuzzier'. The area of view can also be lowered, and the viewer should change place to see totally different elements of the scene. This requires very exact relocation of the developed holographic plate. The embossing process could be carried out with a easy heated press. The backside layer of the duplicating movie (the thermoplastic layer) is heated above its softening level and pressed against the stamper, so that it takes up its shape.
