Instrument Five Detail (Nat Chard)

A few details to show the flying paint in motion in the Instrument Five drawings.

I did not post the whole picture of this one with the Drawing Instrument Five First Drawings post, so here it is:

Peepshow Frame (Nat Chard)

The picture above shows the frame and plates for an experimental peepshow that is open and has adjustable planes. It was a test to find a measure for the accommodation the eye would allow from an ideal anamorphic distortion. The two drawing below were made to calculate that distortion for a particular position of the plates for the main two views. The plates have holes cut in them to composit the peepshow views with the place in which it is found, in this case the iCP gallery in Hamburg.

Drawing One (Nat Chard)

Drawing Two (Nat Chard)

The anamorphic images on the plates are derived from a model (furniture by Karen Gamborg Knudsen and Frederik Petersen) with the two principle views shown below.

Here is a film of instrument three in action – it makes some sense of how the instrument works. During the first half the picture plane folds to provide a critical review of the projection. In the second half the model that is projected is moving, both to persuade but also, when the picture plane is folding, to try to insist on its opinion.

A series of paint throws at Instrument Seven.

Note how the picture plane catches mostly the splatters that come off the drawing pieces  except at the right hand end where some of the main throw is caught. The folds int he picture plane are much more subtle than in the previous instruments and have a much greater effect. The degree of fold can be seen in the previous post.

Instrument Five (Nat Chard)

In the picture above you can see the view the catapult that is going to throw paint has of Instrument Five. As noted earlier, having the folding picture plane behind the drawing pieces means that many of the subtle splatters of deflected paint are obscured by the main body of paint that misses the drawing pieces and deposits a large splat of paint on the picture plane. The same instrument can be seen below, showing this relationship from the side.

Instrument Five (Nat Chard)

Instrument Seven has the same chassis as Instrument Five but has a new picture plane that sits adjacent to the flight of the paint (see below). The folding picture plane has adjustments between each individual plate plus the whole picture plane can rotate slightly. The plane is set up so that the area closest to the drawing pieces forms a harbour to protect that part from a direct flight of paint. Some of the direct flight can catch the back end of the picture plane (or the front if the catapult is turned far enough.

(Above) You can see how little of the Instrument Seven picture plane sits behind the drawing pieces.

The Instrument Seven drawing pieces are also developed to be more robust and larger targets for the paint. We are no longer discussing the Bird Automata test track in this instrument – the drawing pieces shown here are a media test to push some of the thoughts about what the drawing pieces could achieve. There is a main wooden piece that is protected by a number of slatted screens. as the paint penetrates the screens to cover the wooden piece the slats become more opaque to the flying paint.

I will post some images of Instrument Seven drawing tomorrow. Below is one of Instrument Seven’s drawings.

Peepshow Ladders (Nat Chard)

A study for some ladders to hold peep shows for an exhibition. Each peepshow would have openings that would allow a view through to the gallery space or to another peep show or a drawing on the wall. In this way the composite view of the gallery from the ladders would be different from at ground level. The view above has one peep show looking through to the anamorphic projection of another peep show. To discuss the idea, models of Van Hoogstraten’s peepshow were used, although new ones would be made for the exhibition.

Van Hoogstraten in Nat's Office

This is a short post as I am away at the moment, but this is a model of Samuel Van Hoogstraten’s peep show (from the National Gallery, London) with the doors removed so that you look through it into my office. The photograph is taken with a camera I built to take the ideal picture to resolve the anamorphic view. The camera is built with a lot of shift to achieve this and to fill the frame. In the peep show there is a disturbance between pictorial and material space and this is played on with a (real) light coming through the doors that lands on the ceiling of the box. The furthest part of the ceiling of the box pictorially represents the wall of the room, so the light appears to land on the inside surface of the exterior wall it comes through. More paradoxical shadows. As we implicitly believe light, this disturbance takes a moment or two to register.

Van Hoostraten's peepshow unfolded

The unfolded view of the peepshow shows the anamorphic distortions of the room to get it to make sense when folded into a box. The two peep holes can be seen at either end.

There are some views looking back the other way that I will dig out.

Drawing Instrument Five (Nat Chard)

The earlier pictures of Instrument Five concentrated on two of the four instruments. Here is the whole cast.

I will post when possible over the next few days when internet access is possible but there may be some breaks.

Instrument Six set up for direct viewing (Nat Chard)

THe shadow in the submarine photographs (previous post) float in the air because there is a parallax between the flashes of each photograph as well as the parallax between the two photographs. Instrument six has an object to cast shadows and a screen. For direct viewing there are two candles (see above) on a track that have a polarising filter for each candle. There is also a mechanism to adjust the distance between the candles. The screen is a material that maintains the polarisation of light in the reflection, and is made for 3D projection. The observer wears polarising glasses and the parallax between the two shadows locate a single shadow in front of the screen. By reversing the filters the shadow can be placed behind the screen.
When taking photographs a single clear light bulb is used on the same track. A left eye image is taken and then the camera shifted 65mm to the right for a series of right eye shots. For each of these the light is moved along the track progressively, so that when they are each combined with the left eye picture, they place the shadow at different depths.

Shadow from Instrument Six (nat Chard)

To view the shadow in 3D go cross eyed so that the two shadows register one over the other. Try to relax and the 3D image will appear. You will see the shadow sitting a short distance off the surface of the screen. When viewing like this you will see three images with the 3D version in the middle. The lines on the screen are there to help resolve the 3D image and are not needed in the direct viewing version.

Instrument Six (Nat Chard)

Instrument Six is not on the same trajectory as the other instruments, but arrived as a consequence of a conversation about instrument five. I was explaining the drawing pieces to a friend as elements of space that were active.

Drawing Pieces on Instrument Five (Nat Chard)

As an analogy I said that they were a little like the interior of a submarine that was made up entirely of programme and not of passive elements. My friend e-mailed back to say that he had not been in a submarine so I assembled and sent off a pair of stereoscopic photographs I had taken a couple of years earlier showing such a space. After I had sent them I took a closer look at the stereo pair and noticed what was at first an annoying blur hovering in space. Quickly I realised that the annoying blur was on fact the very thing I had been chasing, a paradoxical shadow. It was so obvious how it had occurred that I was annoyed at not thinking of it before. At the time I was working on Instrument Five and stopped work on those instruments to build Instrument Six to play with the possibility of a shadow detached from the surface on which it should by rights be cast. The picture I sent is below but the lower image from another view works at least as well. Tomorrow I will post some more pictures of the instrument and its floating shadows in 3D.

Submarine interior with floating shadow (Nat Chard)

The floating shadow is just to the right of the periscope. If you are new to this blog, yo can view the image in 3D by going cross-eyed. When doing so, place one image over the other until they register. You will see three images, with the 3D image in the middle.  If you are having difficulty pinning it down, try adjusting your horizon slightly to make sure the images are level with each other. The three dimensionality improves if you hold it for a short while.

It is worth persevering with resolving the 3D image – apart from the floating shadows, submarine interiors really come alive in 3D.
