Bean Counting

Randomness is the lack of pattern or predictability in events.  I’ve decided to explore pseudo-randomness as anything thought up by human consciousness can never be truly random.

My method is to divide a 40cm x 40cm canvas into 1600, 1cm squares.  Each square in turn is randomly assigned a number between 1 and 1600.  I’ve then produced a sequence of 1600 RGB 8 bit colours in Photoshop. Each colour was generated using the random number generator set between 0 and 256, one number for red, one number for green and one number for blue.  This is very very slow and tedious!  This is the stage that I’ve reached at present. I will then paint each square with the colour generated in Photoshop.

These are the colours generated so far:

What is the definition of random?

Experiment in randomness – phase 1

Ordered and received Speculative Aesthetics, just started delving into this!

I’m puzzled – Why does yesterdays ‘random’ image contain so many ‘high key’ colours?

Here is an image courtesy of cambridgeincolour that shows a 24 bit depth visualization.  Scroll down the page to see the image.  I don’t understand why there is a lighter zig-zag crossing the image.

Changing to greyscale makes it easier to see the distribution of tones in the image.

I produced a 16 x 16 grid in photoshop, this being the closest to the square root of 255.  Using the RGB colourspace I generated a number for R, G, & B using,’s True Number Generator, range 0 – 255 (photoshop colour integers) . Using Photoshop softwear, in the show colour tab, I assigned the random numbers, in sequence, for R (red), G (green) and B (blue), for each square.  I worked from left to right and right to left on alternate rows.

Of course this is not totally random!  The first decision was to work in a subdivided square.  Second decision was the size of subdivisions.  Third decision was the order in which squares were assigned colours.  Fourth decision was to use the RGB colour space in Photoshop that could generate a possible 16777216 colours.  (The red, green and blue use 8 bits each , which (ie.24 bits) have integer values from 0 to 255. This makes 256x256x256=16777216 possible colors.)

Of course, Gerhard Richter has already done experiments like this!

A short visit to Somerset.  Spent a little time looking for fossils in the vicinity of Ilminster.  This is the worst time of year as the ground is covered in vegetation.

Also went up to Watchet where the Lower Lias outcrop.  Plenty of evidence of an ammonite fauna in the shaly grey mudstones plus fossilized ripple marks.

Reading Bonnard by Timothy Hyman here is a review by Peter Campbell in The London Review of Books.  I’ve always liked Bonnards paintings and am finding this book gives a good insight into his life, ideas and working method.
