My intention was simple: to make visible what normally remains microscopic.<\/p>\n\n\n\n

Abstract holograms store light as extremely fine interference patterns inside a layer of dichromated gelatin. These structures are usually too small to be consciously perceived. By projecting the hologram, the internal light structures become enlarged and observable. What appears is not an added image \u2014 it is the stored light pattern itself, revealed.<\/p>\n\n\n\n

In the projection, the triangular form becomes clearly visible.<\/em><\/strong><\/p>\n\n\n\n

The dark outline corresponds to the glass plate itself, while the interior shows how the hologram actively reshapes the light passing through it.<\/p>\n\n\n\n

Where different interference patterns overlap, the gelatin layer received stronger exposure during recording. These areas appear darker in projection because the structures are deeply inscribed into the material. What looks like shadow is actually density \u2014 accumulated layers of recorded light.<\/p>\n\n\n\n

The projection makes visible how the material has physically stored waves.<\/p>\n\n\n\n

In the close-up views, the complexity of the internal wave structures becomes apparent.<\/em><\/strong><\/p>\n\n\n\n

You can see repeating wave-like formations created by overlapping light beams during the recording process. Where light passes more directly through the gelatin, the projection appears brighter \u2014 sometimes almost white. In other areas, the light shifts into orange, red, or violet tones due to diffraction and spectral separation.<\/p>\n\n\n\n

The darker zones reveal circular and linear structures formed through wave interference. These are not decorative patterns; they are physical traces of light interacting with itself.<\/p>\n\n\n\n

The projection becomes a way of studying light as structure \u2014 not as illumination, but as material.<\/p>\n\n\n\n
