on perception : information and noise

These photographs are taken with a mobile phone camera this evening on Mynydd Llangyndeyrn.

In digital photography, something called ‘noise’ appears in photographs taken at low light levels, making the image grainy.

What we are seeing as graininess is randomness in the image. Either the constantly present randomness in photography – a question of which particular light photons hit the camera sensor in the instant that the photograph is taken; or digital randomness caused by electronic noise from the sensor and the device itself. The conditions were dark this evening, therefore my camera was not able to collect a lot of light, so the randomness or ‘noise’ – which is always present – was this evening overpowering the image or ‘signal’, and the photos were grainy.

I am finding that I am very interested in grainy photographs, and have been deliberately making them – and also experimenting with introducing extra noise into videos and images.

I think especially, I am interested in how low light levels start to break down the camera’s ability to make images, and I find it so interesting to compare that with my own gradual loss of vision over a period of half an hour or so, as the night draws across the mountain from the east.

I have recently been doing some reading about vision and perception, and today re-reading and wrestling with a part about information and noise in perception. These walks on the mountain, and the images that I am making are helping me with making my understanding more practical.

One author I am reading, called Mark Taylor, explains aspects of the neurology of perception, and says that in our perceptual processes, information emerges from noise through progressive processes of ‘screening’.

He also says:

“There is no such thing as absolute noise; or, in different terms, chaos is not the complete lack of order but an alternative configuration that generates static for established schemata. Noise is information in the process of formation. What counts as noise and passes for information is relative to the level at which processing occurs.” (Mark Taylor: Refiguring the Spiritual)

The author points out a number of interesting aspects of these screening processes. Firstly, that the unfiltered data (the light in vision), which is not a ‘complete lack of order’, holds patterns that ‘sculpt’ the eye and brain. Secondly, that when information passes through our perceptual and cognitive screens or filters, the filtered parts do not ‘disappear’, but create resonances which ‘cannot be clearly articulated’. The author likens this to a penumbra, the partial or fuzzy area on the edge of a shadow, between shadowed and lit places. Thirdly, the structures of the filter, the structures distributed across the brain, very much influence and determine the perceptual experience – so seeing both takes a little time, and is made possible through accessing and using memory of past experiences.

This gives what I think is a very interesting model of how perception and thinking work, which the author states is very different from the ‘traditional philosophy of the cogito that informs much of modern philosophy.’

It is a model which includes a ‘cognitive unconscious’. (A way of describing these incredibly complex networks and processes of filtering and processing the information (and noise) which happen outside of conscious awareness).

The model is non dualistic – it doesn’t divide things up into mind and matter. It treats the various processes: light, chemical, mental, as similar – ie. as information and screening processes. Consciousness, thinking, is understood in this model as something which is an ’emergent phenomenon’ of these information processes.

Mynydd Llangyndeyrn

Arriving at Mynydd Llangyndeyrn at quarter past four, and walking the short way up, past the stone circle and the trig point, circling back round. A clear sky and cold today. These photos taken using my mobile phone, near the top. Walking down in the darkening.

shifting sands

Some days I’d like to have an overview, of my life, of my work. See what the pattern is, that can’t always make out. Climb to the top and look out over the sands and the waters.

As a person might climb to the high point of the castle at Llansteffan, and stand and look over Carmarthen Bay, and try to take a reading from the shifting sands.

Here are some questions:

What and who am I grateful for?
Who do I need to forgive, and do I forgive them?
From whom do I need to seek forgiveness?
And do I forgive myself first of all?
What do I love and who do I love?
How do I choose to live my love?

hope and art 2

Today, I’m thinking and writing again about hope and contemporary art.

The thought which I want to follow up just a little today is that an art which is hopeful must address trauma also. It must look at the past and it must look at violence, and it must seek to be with the pain of it, to do something with that pain.

In 2019, the Prix Pictet photography prize took as its theme ‘hope’. One of the nominated photographers, the Côte d’Ivoire artist, Joanna Choumali, exhibited a series of photographs taken within several weeks of terrorist attacks at the beach resort of Grand-Bassom, Côte d’Ivoire in 2016. Choumali had taken the photographs on her i-phone, had printed them in small format on canvas, and then had embroidered on top of the canvases with bright threads. The embroidered series of photographs ‘ca va aller’ are shown on her website:

I saw the exhibition of these photographs in the V&A Museum in London in 2019. Choumali’s photographs are small in scale but very powerful. You must come close to see them, and the scale gives an intimacy, a direct connection to the artist working on the photographs, purposefully going towards the pain and trauma of what has been left behind after the violent attacks.

Choumali comments about her process that:

” Each stitch was a way to recover, to lie down the emotions, the loneliness, and mixed feelings I felt. As an automatic scripture, the act of adding colorful stitches on the pictures has had a soothing effect on me, like a meditation. Embroidery was an act of hope, as well.”
