A practice of painting : living with the reception and generation of image on the visual threshold
… the body of the text as an illustration of the visual dialogue between my own work and theirs. The text closes with a final reflection and appendices containing my own surveys of the three primary texts. My painting practice is primarily concerned with the different modes of image reception and …

Discomfort glare, light scatter, and scene structure
… visibility is a measure of how far above the visual threshold a task's contrast is). Stiles distinguished disability glare, a light scatter effect, from discomfort glare which was glare that could not be attributed to light scatter. The distinction made by Stiles resulted in the separate …

Image based analysis of visibility in smoke laden environments
… and computer modelling. Unlike the traditional threshold of visual distance, visibility in the current study has been defined as a continuous function changing from clearly discemable to completely invisible. It allows the comparison of visibility under various conditions, not just limited to …

New opportunities for photon storage and detection: an exploration of a high-efficiency optical quantum memory and the quantum capabilities of the human eye
… by discussing our work to investigate the lower threshold of human vision and the eye's potential as a single-photon detector, using a custom-built single-photon source, and a novel two-alternative forced-choice experimental design. Our preliminary findings show promising data that support …

Testing the limits of human vision with quantum states of light
… station can measure the perception of very weak visual stimuli (including the weakest flashes of light ever directly tested, with just ~3 photons absorbed). We present two proposed experiments to test quantum effects through the visual system, which could contribute to our understanding of …
