BEAUTY IN NUMBERS

Here is an image I created inspired by  =

1/1.618

Commonly known as the Fibonacci sequence  after the nick name of an Italian mathematician (although actually found to have been discovered much earlier by an Indian musical theorist called Pingala – known as the maatraameru)

The sequence is simple (as easy as 1,1,2,3 : ) – in integers it goes:

0,1,1,2,3,5,8,13,21,34,55,89,144,233

and so on

The rule of the sequence is to add the number to the previous number… Here is a great video explaining how this can be worked out  visually and where this occurs throughout nature:

Once you are aware of it you start to notice it in the natural beauty of everything – from diagrams of the inner ear…

to, DNA, hurricanes, galaxies…

…to the subtlety of (the very costly – according to Steve Jobs biography) apple logo:

I mention all of this – as the psychology of beauty – as far as I understand perception of beauty is measurable – as cells symmetrical when perfectly formed – while a small amount of asymmetry can add to a ‘perfect’ image to show the flawed humanity that we relate to as it shows an off confidence – or the ability to be so confident we can afford to mark ourselves unconfident (like a jaunty top hat or a girls hair covering one eye or a piercing on one side of a lower lip)… this numerical sequence can also adhere to art inorder to create a response of natural beauty in a manmade construction.

So beauty is not subjective but actually a curved line that creates a rectangle that generates a ratio of…

4K TIMELAPSE: TEST

WATCH ON YOUTUBE AND SELECT SETTINGS QUALITY AS ‘ORIGINAL’ TO EITHER SEE 4K OR WATCH YOUR COMPUTER CRASH!

SPECS:

Test footage to figure out workflow for 4K time-lapse.


Shot by Josh Randall and Alistair Campbell.

Using Canon 7D – 8mm fisheye – intervalometer – shutter speed of 125th to 30 seconds- iso ranging from 160 to 6400 Intervals from 15 to 75 seconds between 19:30 – 01:00 hours.


Location: M5 motorway between Bridgwater & Highbridge where artist Serena de la Hay’s Willow Man sculpture stands 40ft high since it’s original construction in 2000.
2010 – 2011 saw building sites around the sculpture with a modern estate & 800,000 square foot warehouse for supermarket retailer Morrisons.
RAW L format stills were 5.8k, then placed in screen width of 3996 pixels x height of 2160 pixels (due to end youtube limitation) on Adobe After Effects – with duration of 1 frame/still on a 24fps timeline.


Image scaled down 78% to get maximum image within scaled down screen’s different aspect ratio of 1.85 – then rendered & exported out as lossless with ‘animation’ setting as 8 second 3.6GB QT
Youtube has max file size of 2GB so file via ‘Compressor’ to Apple Pro Res 442 (HQ) bringing file size to 764.7MB

PERSONAL VERDICT on TEST:
This is about 2 days work for 8 seconds of footage! – the high resolution probably won’t play on the majority of home computers smoothly at the maximum 4K – but the fact that youtube is already going there shows it’s preparing for a future where the filmmaker’s quality of image is important – which I feel they should be applauded for coming from the VHS generation where the distribution (or maybe the audience) simply did not give a shit about quality.
The test was a good idea – as just discovering how to get to location via the new estate and the fact that there is a moat blocking access to the Willow Man by at least 50ft was useful.


The test was done at dusk to get an idea of the change of light to see how the camera would cope from the range of overexposed lens flare sunset and capturing detail in the night sky – but I hope to capture a period of at least 16 hours for the final one. I will try lenses between 10-20mm as the 8mm may have been too wide to appreciate the detail – although it captures the expanse of night sky well.
Having previously interviewed Serena de la Heyabout her work, it became clear that sculpture’s creation had become political, having been a feature in a previously barren area which helped attract the land to be sold for housing and the Morrisons warehouse in the development of Bridgwater brought about by the planned increase of jobs to the area with Hinkley C – a nuclear facility on the cost. As the willow sculpture becomes tatty and frayed – Serena has no further plans to maintain it – perhaps through resentment of it’s intended purpose to what it has become…
The artistic statement of the giant human figure is now dwarfed by the industrial neighbour it has attracted.
There is an unexpected artistic statement here as the original large expression of the humanity glorified as part of nature was reminder to the masses driving an otherwise humdrum M5.


This classical form is now a contemporary expression of the forgotten glory of human nature as it falls apart to the ugly functionality of a capitalist structure when the human is a product in a system.
The wide angle is important as the image frames the ugly houses of a modern estate, the motorway fading into depth forcing an either coming or going direction to the drivers and a warehouse of a food retailer with a successfully cheap brand – generating revenue by supplying low quality food to the nations. In the middle of all this is the decay of humanity but ultimately there is the UNIVERSE – the STARS – the SUN take centre stage reminding us this moment is an insignificant slice of time – making the capitalism bleaker and the unique existence of humanity even more remarkable.

For this test I was pushed to use new software – as I am fluent with Final Cut Pro but it’s 2k architecture meant I had to venture to Adobe’s suite to do this.
Adding sound on After Effects is not as simple as FCP so I gave up on audio with the 4K resolution and added one of youtube’s tracks… On the finished thing I will have something composed that captures the sublime, the forgotten and the system – with the all important perfectly timed key change from day to night for full impact.

Also – extra batteries – more CF cards – more people to allow shifts – warmer clothing and be more aware of where I put my lens cap and several flasks! All those common sense things will be prepped for the finished shoot 🙂
As my first attempt at 4K timelapse – I have discovered a vegan filmmakers answer to fishing – as there is nothing like an excuse to hang out with others in nature for extended periods of time…


Full thing coming soon – watch this space!

UNDERWATER 360 TESTS

The icci360 bods at Plymouth University are remaking their underwater camera with GO PRO HD HEROS – the reason for this is they have wider lenses(170 or 127 degrees)

This helps because as soon as you put a camera under water the millimetre measurement of the lens is no longer relavent due to the refraction of light through water… here are some images to illustrate how refraction works…

This is what as known as the angle of incident – where the light changes angle through the different substance…

And so starting wider allows their to be less blind spots for the dome projection – where the 5 images need to edge blend into one another

However another issue with the GOPRO HD HERO 2 is that the image goes soft with it’s curved lens underwater – so people have been experimenting with adapting the lens flatter for a much sharper image…

The other reason for using the GO PROS is that they now have a synch cable – meaning one button can switch them all on at once – allowing a bank of the things to be used together to get bullettime footage out in the water – as done for these surfing commericals

EARLY SOUND RECORDING

So far, like all bad filmmakers, I have neglected sound a lot… The truth is audiences are happier watch bad visuals with great audio than vice versa.

Here is the first ever recorded sound – someone signing Au Clair De La Lune:

Edouard Leon Scott de Martinville recorded this with his invention, the phonautograph – a device which drew a line attached to a membrane that vibrated from sound waves, by drawing the movement of the sound it was able to be reproduced by scratching the markings into a material that could then reverse the process and move a diaphragm recreating the noise, then amplified by a large cone that bounces the sound waves along making them bigger

SHOOTING FORMATS #0.8: CHRONOPHOTOGRAPHE

Étienne-Jules Marey invented this 12 frames a second camera in 1882. Like a cinematic DaVinci he was curious to take apart the anatomy, aviation and structure… wanting to analyse it using photography. 

Creating the Chronophotographe made it possible to capture locomotion by taking frames in quick succession all onto one image, which gives this ghosting effect of staggered movement…

SHOOTING FORMATS #0.6.1: Subtractive colour

To understand more about colour, first it’s essential to know how we perceive it… here is a talk on it…

SHOOTING FORMATS #0.0: Observing the universe

In the beginning of all filmmaking – was a bunch of humans with a curiosity and a need for stories.
It is recorded the Egyptians first thought the earth was the floor of a massive box shaped universe…

Around 3500 B.C. Phonenicians recorded a discovery while cooking that the properties of the sand they were cooking on changed…

Some time later the Greek Aristophanes (who also figured out an estimate of the diameter of the planet using shadow measurements over large distances) used glass lenses with water to magnify the sun to ignite a fire.

Then for some time the only realised application of a lens was eye sight correction… until 1608 onwards where the discovery that two lenses a distant apart can magnify sight. This led to Galileo Galilei using this technique to improve the practice of star gazing.

Astronomy – coming from the Greek word as “Law and Order” is the study of the arrangement and movement of the stars – this long distance called for exact precision and meant early development in lenses were way ahead of the other elements of a camera as we know it today…

SHOOTING FORMATS #0.3: AgNO3 & Daguerreotype

Niépce then began experimenting with silver compunds based on the German Professor, Johann Heinrich Schultz’s discovery in 1727, that silver nitrate (AgNO3) darkens when exposed to light. (a joke to remember this chemical expression is – Does accepting not knowing how photography works make you an AgNO3-stic) The reactive silver nitrate is nasty on human skin, creating an irritable discolouration. However excessive Colloidal Silver can be used to stain a humans insides – which is why this man turned blue…

In partnership, Niépce and Louis Daguerre (in Paris) refined the existing silver process. In 1833 Niépce died of a stroke, leaving his notes to Daguerre.

While he had no scientific background, Daguerre made two pivotal contributions to the process. He discovered that exposing the silver first to iodine vapour before exposure to light, and then to mercury fumes after the photograph was taken, could form a latent image.
Bathing the plate in a salt bath then fixed the image.
On January 7, 1839 Daguerre announced that he had invented a process using silver on a copper plate called the daguerreotype, and displayed the first plate. The French government bought the patent and, on August 19th of that year, made it public domain.

Leading to this image of Paris, where the long exposure meant the only people who stopped long enough on the busy street to become recorded, was a shoe shiner and shinee…

SHOOTING FORMATS # 0.1: CAMERA OBSCURA

The camera obscura – meaning ‘Camera’ from Latin, locked chamber and ‘Obscura’ meaning Dark, is exactly that, a darkened chamber. A small hole allowing bright light waves in to travel across and reflect off of the chambers wall projecting an upside down image of the world outside. It was a technique used by artists to trace reality and became the precursor to photography.

This was discovered before 470 BC to 390 BC with mention in the records of Mo-Ti, the Chinese founder of Mohism. The video below shows how simple it is to create (as well as going on to make a 3D version!)
