cool color composition ... try rendering with antialias
but the spiral is somehow nice positioned 

Thanks for the nice comments Trifox, glad you like the positioning.

BTW, I did try rendering with anti-aliasing before posting. I often try both because when the noise in G.I. as used here and in other formulas is removed it can make a significant difference.

In this case with AA on the character of the 'noisy' spiral arm changed so much that it lost much of its mass and tone. This changed the character of the image considerably which significantly altered the visual balance of the figure to the ground so I decided to leave it as is.

If I was going to do a large version of this for rendering in print I'd go back and see if I could achieve a similar overall visual effect without the noise.


Of course   

Thank you for the kind comments Lycium.

I looked at the Fibonacci Sequence reference, and can see the relationship. I guessed the basis for the positioning might be the Golden Proportion which is a ratio of 1 : 1.618 (or .618 : 1) which is quite close.

See:

Out of curiosity I opened the rendered image in PS, enlarged it 5x so I could measure accurately, and cropped from the bottom of the image to the top of the brown spiral arm. I double checked to be as sure as I could be that I got it to the pixel.

The original is 768 pixels in height, the height of the image cropped to the top of the spiral arm is 474 pixels. This is within about half a pixel of the Golden Proportion of approx. 474.64... (i.e. 768 x .61803)... or about 1/8 of 1%.

 

I had no conscious thought about the Golden Proportion when I was working on it, and doubt I could hit it again if I tried a couple dozen times !!! (My eyesight isn't that good!)


When I posted this observation on the class BBS Janet Parke kindly posted for me the UPR with a GP grid layer. When I saw the image with it there was another surprise. The center of the spiral is on a vertical GP line!





So then I checked my Mandelbrot prototype image from the class. It's also a spiral but with a single long gently curving arm sweeping upward before it closes near the top of the picture frame. The bottom of the closing spiral rests on the upper horizontal GP line and the center is also on a vertical one. I guess I like that arrangement.

Although I'm very familiar with the Golden Proportion as a basis for composition, I don't think I've never used it or any other geometric means for composition. I'm very much in the 'it looks good about here' school.

Hope you found this a bit amusing I like did ;o)

BTW Lycium, I've spent some time savouring your images on DA and am deeply impressed not only by your artistry but by your ability create software tools that express your artistry so incredibly well.

There are many stunning images in your gallery. Oneiric is probably my favorite, but I also really admire Piezo, Spring, and Elements in the H&M section, and Cities of Tomorrow, and Lexi Zero & Lexi Two among others. There's great variety in your work and exemplary results in all styles.

Very inspiring artwork!

cheers,

so, what does the grid mean ? areas of interest in an image ? 

ah i see why i am no artist

@_db_ 
this fractal course seems to be a very pretty and detailed one, perhaps you can post a link in the links section to the course details!


 

i am thinking about a wiki like section on fractalforums.com containing detailed information about various fractal/art topics, e.g. golden ratio/coloring algorithms/antialiasing/complementary colors and stuff like that, but i am not sure where to start, if someone might help, please contact me 

Don't feel bad, I've put a fair amount of time into trying to learn this composition stuff and I'm still no artist. 


Composition, Golden Proportion, etc. aren't covered until the 3rd course in the series which is Ultra Fractal Artistry.

Their courses are here:

A Wiki sounds good. I could contribute a little to it in terms of info. I also have links to some good information on some on the topics which you've mentioned.

Me too!!


Thanks Matt. Although I was a maths major in Uni I can comment on why either. Maths alone doesn't make art...
