I had an idea about imaging, quite a while ago, that I intended to use on my site. But as I have no-one to help me with this, I might aswell throw it on the table. You´ll have to bear with me though, because I am not accustomed to explaining technical things. The idea is to play around(=spielerei) with the colours of any given picture. Every digital picture is made up of pixels. Each pixel has a colour code. For ease of reference, I shall explain the principle, using your basic square, which is made up of nine smaller squares, each of the same size. The big square consists of three times three equals nine smaller ones. The outer eight little squares, which all touch the borders of the big one, have the colour green(just an example). Which just leaves the middle one, which has the colour red. Now we assign a letter to each little square, starting with “A” for the top left one and ending with “I” for the bottom right one. Everyone with me so far?
Next, I need to talk about the spectrum, which is made up of the three primary colours(red,yellow,blue) and their opposite secondary colours(orange,green,violet) and every shade in between. First imagine a rectangular strip holding the entire spectrum. Now bend the ends together to form a circle, which leaves a white circle in the middle(the white is arbitrary!). Again for ease of reference, we will divide the circle into 360 degrees. The starting point “zero”, you can fit in anywhere you like, as it is just a convention. You could put it on pure red or anywhere else.
My idea is to take an image that I like and let the colours of each and every pixel in it alternate between its original colour and its opposite colour on the spectrum circle. The speed of alternation would have to be experimented with to find the optimum result. I propose to start with an alternation of half a second. Returning to our square, you would have the smaller squares A,B,C,D,F,G,H,I, in red for half a second and the middle one E would be green for half a second. The next half second you would substitute them with their opposite on the spectrum circle, which is extremely easy in this case, because green is the opposite of red. You let the alternation be continuous and judge its effect with your own eyes. If the interval is too long, shorten it and vice versa.
This was the simplest example that I could think of. Next you take your favourite picture, design the software to give every pixel in it, its number of degrees(0-360º) on the spectrum circle and alternate all of them simultaneously with their counterparts at optimum speed. Got it? If anybody tries this, please let me know the results!?
