Cinema Metrics and the role of the Cinema Building in Narrative development

I am presenting at the Ghent Early Cinema Conference and will be showing my idea that Cinema design, the building itself may of played  a part in the adoption of narrative forms of cinema films, or those forms that were more story and duration based and required suspension of disbelief to read and enjoy.

I will do this by sketching out first how cinema and theatre related through the agency of the actual building and how some early cinema buildings were really theatres.

Then, after some examples of early cinemas that started to do away with ‘distractions’ like a stage, pros arch, fly loft, wings, apron, lighting, etc I will  show how as the cinema space became more simplified this in effect took place in parrallel  to narrative forms becoming more central and dominant in exhibition.

Is this a chicken and egg problem. How can it be shown that the audiences physical behaviour during narrative required a particualr set of environmental forms that may or may not have been in place during the transition period? And if they were not in place how can we see their effect in building design and towards which ends?

I will be looking at a selection of early plans in terms of the period they were submitted and what was common in Cinemas at the time, then I will be examining particular design features like projection throw, rake angle, seat angle, relation to stage and wings,and how the screen gets presented to the audience.

Of course we know that early Cinemas took their architectual cues from Theatre. BUT, and this is decisive, theatre is an entirely different technical environment that has very specific environmental forms and these differ radically from what simple, Cinema proper, buildings became.

 

 

As an informing idea for another project I am going to start to collect cinema metric data.
I am narrowing this down to the following:

Compass bearing of projections : Angle of rake :

Thats it!

I could add Throw (film gates to screen) in M/mm, number of seats. To allow venues with multiple screens each screen could be numbered.

So an example might be;

105° : 5° : 20M : 350

This example is made up.

This doesn’t seem to tell us much. But when we have a data set including many different places you should be able to start seeing patterns.

Shutter effects

Heres 2 photos taken during a shutter test where the blade has been almost closed over and a very tiny slit is all that lets any light through.

This would produce a shutter speed too fast for effective exposures (in convnetional use anyways). The LED light source illuminating the paper on the other side of the gate flickers and this produces the strobed scans of the slit as a photo is taken with an iphone4.

 

Lens mounting solutions

Using a linear stage from Thorlabs and some basic metalwork I can now accurately position a digital camera or just the lens to line up with the camera.

A bit of tweaking to get the relay lens bellows to fit. All that needs doing now is take up motor electrics, then I’m ready to try some film to film tests.

During tests very annoyingly the Nikon remote release socket stopped working and the camera needs to go off for repair. Having digital preview is useful for predicting problems for later film>film work and for digitising friends work  BUT my whole artistic project is about using a |film > film > projector| workflow so the more I gear up for that the better. Digitising becomes another distraction. You end up fucking around in editors, compiling and rendering things. The quick spectacle of seeing video clips (ok I’ve posted a few) starts to take over.

The creative potential of unexplored techniques like ‘shadow’ printing (my invented process that dodges and burns during contact printing) can never be moved along if Im always scanning and playing with video.

I did some light level tests also. The LED array Ive been using for some scans is WAY dimmer than the halogen 11ov lamp. Although its whiter and cleaner it may well not work for film.

 Is there such a thing as a digital contact print? ie a scanning process that does not ‘image’ via a lens but instead lays the film upon the sensor?

Also been looking at telecentric lenses for the Oxberry. These lenses offer a very accurate profile and were the types of lenses used in ILMs quad printer and the printers that Richard Edlund built at Boss the Zoom Aerial Printer and the Super Printer, both 70mm.
