Acrylic creates a semi-transparent 'canvas', which stands proud of the surface onto which it is fixed by means of four sturdy wall fixings. This means that light interacts with the image, which is therefore back-lit and creates an almost three-dimensional effect. The process is particularly effective for the display of monochrome or minimalist photographs as the white background is replaced by the crystal-clear background of the acrylic, which gives a feeling of perpetual depth.
