Sounds & fog....

Characteristices of sound & light within fog:
  • the speed of sound is greater in denser materials, so the velocity of sound is greater in fog than in normal air.
  • distant noises mostly sound low and dull; nearer noises are higher and brighter
  • fog carries sound more efficiently than dry air, so even the faintest noises drift for miles. You can never judge distance accurately from the noises you hear in fog because they will probably be distorted in some way.
  • size can become distorted too; when visibility in fog is between 30 and 150 yards (about 25 to 140 m), vessels and other objects frequently appear twice their normal size. This illusion effectively doubles the speed of approach...
Fog Shadows
Shadows are cast through fog in three dimensions.

The fog is dense enough to be illuminated by light that passes through gaps in a structure, but thin enough to let a large quantity of that light pass through to illuminate points further on. As a result, object shadows appear as "beams" oriented in a direction parallel to the light source. These voluminous shadows are due to the same cause as crepuscular rays, which are the shadows of clouds, but in this case, they are the shadows of solid objects.

InHabit - intial thoughts

Inhabit the space above....clouds...somewhere to sit and linger....make people look up.
Being in fog makes you:


  1. feel like an individual (as opposed to a mass of people)
  2. feel anonymous
  3. hear things differently
  4. see things differently
  5. move more cautiously, slowly

Clouds/mist/fog information:

  • Fog can be simply defined as a cloud touching the ground.
  • Fog is denser so contains more water droplets than mist.
  • Fog has a visibility of less than 1000m. This limit is for aviation purposes, but for the general public an upper limit of 200m is more realistic. Severe disruption to transport occurs when the visibility falls below 50m.

The atmosphere includes water vapour; a certain amount of water can be held as invisible water vapour at any given temperature. If air is cooled it holds less water and becomes super saturated. At saturation point, some of the water has to condense to form water droplets, which forms cloud.

Types of fog:

  • Radiation fog = fog formed on clear, still nights when the ground loses heat by radiation, and cools. The ground in turn cools the nearby air to saturation point, thus forming fog.
  • Advection fog = fog formed when very mild moist air moves over a cold ground especially in Spring when mild winds move across the country over icy ground. The lower layers of the air get cooled down rapidly to below the temperature at which fog forms.
  • Hill/upslope fog = fog formed as mild moist air is forced to ascend a hill or mountain range. As the air moves up the windward side of the mountain it cools down, and again if the air becomes saturated then cloud is formed which, if below the top of the hills, gives fog.
  • Coastal fog = fog which forms when moist air is cooled to saturation point by travelling over a cooler sea.
  • Steam fog = fog seen rising from the ground after a rain shower. If the ground is warm, the water from the shower may evaporate. If the air above it is saturated and cannot hold any more water, the excess moisture condenses and looks like steam.

Treshold Final Presentation & Critiques




(NB. the quality of the video clip above is not as good as the final presentation - in order to post on this blog I saved it in a smaller format)

Comments below are peer reivew critiques of my project.

Threshold - plan for final products

Requirements: 2 A3 sheets plus a 'thing' (eg. model, animation etc.)


  1. A3 sheets:

(1) plan of building with potential locations of cameras, projectors, sensors & screens;

(2) initial investigations and map of how I ended up with the final design - images of the resin experiments, graph, info on the glass to use and technology

(3) take screen shot of final movie image to blow up (or a series of images)

  1. Thing: animations of what the doors could look like ie. a series of video clips

To do: rotobrush image of me walking in, and out, overlay onto existing movies but with the addition of screens. Investigate effects on the door as it opens

Threshold - video editing...

My project has now morphed into a video editing education for me...

"Threshold" = transition zone, merge of 2 places, point of balance before entering one place or another

  • the point at which my awareness of the 'outside world' (vastly different from student life) and 'design studio world' is in balance - just before one or the other takes over.
  • represented by the doors between the courtyard and the foyer area containing the lift/doors to stairs/doors to student centre/door to studio - the glass separating in from out.
Rationale for location: this is where I often collect my thoughts then empty them like the cup of tea analogy from the trashcan project. I come into the studio from this direction (not the student centre).

The reflections in the doors remind me of where I've come from and the action of opening the doors breaks this reflection - shatters it - and takes me to the place I'm going to.

I'll be experimenting with the idea of projections of a live video feed onto the glass doors using high tech surfaces (see Technology page):


1. Where I've Been - to represent moving away from this to something new

  • (coming in): trees in the courtyard, the calmness outside, an image of me walking away from this, or,
  • (going out): images of the studio, the busy activity, the concentration of people working, eating, talking, lots of movement, an image of me walking away from this

2. Where I'm Going - to encourage an awareness of where I'm about to be, and get me in the correct frame of mind for this

  • (coming in): images of what's going on in the studio
  • (going out): images of the outside, the weather, the trees etc
3. Merging of these (where I'm going/where I've been)
4. Adding in some still images from the initial investigations of 'merge' with carpet/resin

I'll create some video images of these ideas and see what works best in terms of representing the initial Threshold idea.
