Pinhole/Camera Obscura                             

 

 

                                         

 

 

Perhaps the first historical recored of the camera obscura is to be found in the writings of the Chinese philosopher, Mozi (470-390 BCE). Mozi described the image in a camera obscura as appearing upside down because light travels outwards in straight lines from its source..

 

 

 

 

 

‘Upside down’/’inverted’. The ‘world turned upside down’ as trope (whether read as reported state passing ethical judgment or as subjunctive wish – either way an ideological anamorphosis). As symbol or symptom, cause or effect, we are offered two broad connotations: as negative, indicative, critical, imputing chaos, implying things are ‘not quite right’, ‘out of sync’, ‘out of kilter’, transgressing laws or Law; and… (conversely) a positive reading, as it should be, subjunctive, but where the ideal is not yet clear, is presented as inverted, distorted, a stage in the process (a partial anamorphosis); the new vision, or point of view is not yet completely crystalised. A transvaluation of values not yet completed… The ‘world turned upside down’, but not yet righted.

 

Camera Obscura; Camera Lucida, both made from light; a room of light – enlightening.

 

Made from two complementary layers: with the (partial) occlusion of one surface (rendered as the background), or the synthesis of both…

 

 

The Pinhole Technique and Meaning. Uses: (from Abstraction to Representation: Inversion, Texture and Meaning).

 

 

Camera…

 

I Abstraction/Form (Camera Obscura as abstract art). Product of the conflict of planes or layers; of the vertical and the inverted, of light reflected and light projected. Background and superimposed image in complementary contrast. So featuring a special sense of texture – coming in part from the projection (incoming light) and in part from the receiving surface (the back drop).

 

Project/projection. The Camera Obscura as a simulacrum. As an allegory of human consciousness. Echoing the tension of subject and object: made from the interaction of ‘active’ and ‘passive’ elements, from ordering concepts (our past as the receiving surface) and perceived sense data (the present ‘eternal’ of perception as the projection). The influence of the back drop or background as ‘previously received’ or ‘shaping’ concepts, including words/images on wall; projected… with ‘incoming’, as ambiguous content manifesting different ‘definitions’ according to the terms or forms of the ‘background’. The ‘back wall’ of the projection; our forward wall of perception. Furthermore: If the Camera Obscura is in fact a room (with the projection – either natural, as from ‘window’ pinhole, or as a copy coming from a projector, onto a wall) then the sense of a room as an image of human consciousness, our ‘room’, is reinforced. In Camera.

 

The room of the self… caught in, caught by, the contradictions of the pinhole world… an image in the ‘room of the self’ (so space of the subject with its object inverted upon it…). Truth of our machinery of perception… The parts of the self… one step back (as with the image prior to re-inversion…). Before being recombined with selected data from our other senses to form our conscious ‘picture’ of reality. The theatricality of all representation.

 

Likewise the frame of the projection, the frame of the image, may be read as signaling the limits of perception (the limits of our ‘room’) just as the presence of the projection signals the eternal present as the frame of what is human, our experiential meta-set (last word or final point of view).

 

Question: which (kind of) image (content) is best to illustrate this parallel (to make it more than a reading based upon the form); what would we need to go beyond abstraction to a specific content? To pass from allegory to illustration. The search for apposite imagery…

 

 

II Meanings/Content (the twin layers of the Camera Obscura as carrying conceptual force). Essentially the search for the medium’s proper material, proper content; that which suits it best, that which it suits best, as giving reign to meanings better than in other forms of expression. Marriage of form, content and means of expression to offer the possibility of meaning. In effect two approaches, as with the application of form (true even of a ’lighter’ form, say of the Villanelle, etc): either to search for a ‘suitable’ content or topic; in which case we have the allegory of the topic as ‘related’ to the formal aspects of the image (the image that suits the ‘frame’): or to rely on form to capture content and make it its own – even at the cost of self-parody or irony (the ‘frame’ appropriates the image/ a change of form changes the content).

 

Where else do we find reversal: in nature, or by implication (in fact or in desire, with the sense of the indicative or subjunctive in conflict or contrast)? In water. In reflections in water (as in landscapes, buildings or people on the other side of a stretch of water… so reflected before us, inverted…). Something perceived, or only perceivable, in reflection, on the surface of water… or any other reflective surface that lies in between us and the image source… What is added: the inversion (conceptual, political… product of reflection); and the new texture of the reflective surface (symbolizing thought... reflection). There would appear to be two clear formal options…

 

(Project/projection A) To show the inverted reality as such (as the pinhole image presents it, inverted…): what content or bundle of meanings is best suited to this treatment? To being shown upside-down? (The meaning, or content of expression, must suit the means of expression, so short-circuiting shallow point-making or opportunistic polemical effects…plainly put, simple inversion as statement is insufficient). Potential content: any image that gains extra meanings from being upside down.

 

For example: a landscape in which an inverted skyscraper first appears as a pillar, then we realize that the ‘sky’ is in fact a city… or the presentation of an institution (heavy-handed?) or scene of an event…?

 

The reflection of someone, something as if (inverted) across a glass table (possibly offering additional or biographical, often ironic meanings - in effect a commentary).

 

Further: the showing of an object AND its reflection together; again as if over water, or a glass table – as if a horizontal fold, a horizon as fold, constituted their possibility. Conceptual or mainly aesthetic (like ‘B’ below…). So ‘naturalising’ the inversion (lessening its defamiliarising effect) but not necessarily diminishing its conceptual, interrogative force…

 

(Project/projection B) Conversely, we might wish to show the inversion, re-inverted (right way up) – so an appropriation of the texture of the pinhole image (pinhole technique as means to a texture); which is either used as such or else projected onto another surface - this ‘righting’ is after-all what our brain does with our image perceptions. Or… an inversion of the image of the pinhole image (its righting) as projected onto a recognizable surface (say the wall of a room, with doors, wardrobe, etc) such that it is the surface that supports the image that is inverted, and the pinhole image (of something that is projected onto that surface) that is righted. In which case it is the background, the recording surface and its texture that becomes the ‘ghost’ – inverted source of the uncanny effect.

 

If using reflections on water in order to right the image… The major effect here is the apparition of the image with its accompanying texture gained from water, in fact a third layer, including the image’s background or site of projection/reception (assuming this is not plain). An interesting piece of illusionism; with a potentially destabilizing result (the beauty of the texture undermined by the sublime impact of the image, as the brain (half) realizes that the image content should be upside-down, if it is a reflection…). Finally there is the choice of end product as projection, slide or film loop (good for capturing movement, if any) or photograph/light-box transparency - both of these, projection or light-box, as a mimesis of the original conditions of making - or just a plain photograph…

 

Content: any attractive waterside scene or structure… (practicable as an outside to be caught in an ‘inside’) or the reflection of person or thing on a glass table (much more difficult to set up as a Camera Obscura). Less attractive but with a formally distinct frame: the surface of water in a container (bowl, barrel, pool or puddle) as ‘containing’ the image.

 

Or show both together… side by side - for example if they complement each other in meaning, or better in form, forming a larger whole or overall pattern… (a bit like showing the construction of an image as part of its presentation).

 

In both of these cases (A + B), the showing of the reflection (only) as inverted or righted, also implies the absent (un-representable) ‘original’ image source - but perhaps especially in (A) where the inverted image immediately suggests or points to the absent opposite, the image right-way-up.

 

In all cases the background can or should be used to alter (to ironise or put into question) the meaning of the projected image (or vice versa)…

 

Optics and Openings/Gender. Finding ‘project’ and ‘projection’ as subverted by the hole of ‘pinhole’; what makes the projection (the visual element) possible… is prior. Projection of light as secondary; an effect of physis, and an effect of ‘absence’ – an effect of the form of the body in its relation to light.

 

 

 

Obscura/Lucida…

 

 

Four aspects of meaning.

 

 

If using a ‘reflection’, or reflective surface, as a method of righting the pinhole image’s inversion; then the meaning is as if corrected, as of a corrected sense of vision…

 

I Reflection (from where…?). The uses of reflection. As if seen on the surface of water (or glass or metallic surface) reflected… (origin invisible). Or… from under water… Meaning; as if from inside somewhere (and as an ‘impossible’, so unnerving combination, a reflection that is ‘right-side-up’, destabilizing us even more than the grosser inversion of the image would). Suggesting: rooms; interiors… the self; lyrical subjectivity. Plus the usual sense of remove/dness or semi-presence, of pastness or memory - or future fantasy. (Or is it the background which is thrown into semi-presence… so suggestive of a ‘room’ elsewhere - especially if the image so projected contains movement…).

 

II Superimposition (onto…?). A question of backdrop or background. The effect of the background as being underwater… (as if seen through gauze or silk, or otherwise distanced from us). Objects on/in background (receiving surface) + texture of surface of background + surface of water (or other surface used to re-invert projected image) + projection/reflection… Also the effect of a ‘natural’ or ‘neutral’ room – yet in meaning making nothing is neutral. Just a less suggestive (or less fore-grounded) room versus prepared surface and objects…

 

III In Desire. In subjunctive mode, where hope or wish become read as critique or satire; the projected image as the realization of a desire, as the showing of a desired state - positive or negative. So what is shown upside-down is desired as such… as to be upturned… or (the opposite) desired as re-inverted…as ‘righted’ (as in the introductory comment).

 

IV Temporal. Potentially the present and past/future (presence and semi-presence) together; one overlaying the other; but which is dominant? Ambiguity… Other sense: the absence of temporality (as outside of time, or universal). Eternal: none. Yet some such reading, if not effect, should be possible…? Some degree of ‘ghostliness’ usually ‘means’ the past/future, memory or wish; but ‘outside’…?  One example: a heaven or a hell; but probably only if obvious (if there is a content reference, only if accompanied by a past meaning learnt as such (a specific cultural notion of heaven, hell or eternity). Universal: the outside as foundation; that which we wish to put outside of history as no longer contingent, as beyond historical or cultural relativism (values and beliefs, axioms, the a priori, first principles). Otherwise than other: the Surreal; suggesting the world of dream (also based upon past memory, the experience of dreams). Or alternatively with the projected layer suggesting the future as a kind of vision. Dream vision?

 

If interpretation is open to a number of options then perhaps more important is the search for apposite or ‘natural’, appropriate material; that which brings out the most interesting effects (as for example in the case of an inverted pinhole image shown right-side-up, with waves… to show that it was once upside-down as a reflection); or meanings linked to upside-down-ness (as if a reflection… in water). The double layer also provides potential for irony…

 

Practicality: It may be necessary to take the pinhole image on site, then project its recorded image on to the required setting/wall, and only then record the resulting, composite image. In the case of a ‘staged’ photograph, slide or film projection, if there is movement included in either of the two images/layers involved in the superimposition (inversion and texture being the two important new aspects of this kind of superimposition) and if blank spaces (sky) are found in opposite parts of the composite image, then a complementary filling of space and even movement, preferably in contrary motion, might be employed.
