{SI] Shoot-In - Fractal Comments
One early October Tuesday evening in Newfoundland, Mardon put down
his paintbrush to check the r.p.e.35 newsgroup. (His wife kept painting.) Lo and behold, the SI fractal submissions were on display in their full glory, even before the submission deadline arrived. Talk about efficiency. There's no flies on our Jim, as the saying goes. I wonder if Al is impressed or just glad that the job isn't his anymore. "Natural Fractals" Hummm --- I own a text on Chaos Theory. I've installed Quat and Fractint and have used them on my PC to generate my own fractal images. I've even installed an image of Henrik Engstrom's quaternion Mandelbrot set circa 1992 as my PC wallpaper. All that said, I still have no idea which of the SI submissions is really a natural fractal and which isn't. Unlike image plots of fractal equations, I'm inclined to think that natural fractals exist only in the mind of the beholder. So does beauty, and here's my opinion of both: James Mondor http://www.pbase.com/shootin/image/68336427 I like the film 'feel' and the grain in the dark areas of the background but I'd like to see the foreground leaves be sharper. The white and dark spots on the leaves are also distracting to my eye. What would this have been like without the orange filter I wonder? Any special reason for using it? I remember using a dark red filter a lot for that dramatic looks with B/W film. Walter Banks http://www.pbase.com/shootin/image/68336535 Nice colours! Common wisdom is that tree branches are natural fractals but I don't think that applies to leaves, so a 5 point deduction. As already mentioned, the leaf colours are nice; I wish the sky were a slightly darker blue. I'm glad the image is not over sharpened. This is the sort of content that looks bad when over sharpened. Quercus http://www.pbase.com/shootin/image/68336553 Common wisdom also says ferns are natural fractals but I don't think this is a fern. I can't conceive of those oblong leaves being made up of smaller oblong patterns, etc; no fractal, so 5 points off. I really like the colours. My mother always said that blue and green don't go together but I never did believe that saying. The shadows on the lower leaves and the lack of shadows on the upper ones, combined with the clouds make for a very nice image. Bowser http://www.pbase.com/shootin/image/68336559 Nice image! Are the barnacles the natural fractals or the rust? I suspect the rust is really more fractal in nature than the barnacles but who cares. No deduction because one of them must be fractal in nature. The orange and white complements each other well and I like the composition, with mostly white to the upper left and mostly rust to the lower right. Al Denelsbeck http://www.pbase.com/shootin/image/68336564 How'd you do that? The lily pad looks like it's under the surface of the water but the droplets wouldn't float on water would they? It seems logical that the droplets must be sitting on the leaf but it doesn't look that way to my eye. Intriguing! The veins are no doubt fractal in nature, so do deduction there. To paraphrase our friend Bret, too bad "Elitechrome 100 Hates Lily Pads". "Elitechrome 100 LOVES those bubbles though." Too much washed out green for my taste. Jim Kramer http://www.pbase.com/shootin/image/68336571 It's wet. It's soft. It's somehow connected with the insect world (I think). It may be alive. But is it a natural fractal? Don't think so. Minus 5 points. My favorite part of this image is the one rounded, brown tip of the dark leaf at the top edge of the image and the strands of web that lead down from there. The white strand at the lower left is also interesting but the glob in the middle just confuses me. What is it? Mardon http://www.pbase.com/shootin/image/68338439 I thought about cooking a DVD in our microwave and repeating the fractal image from Wikipedia (http://en.wikipedia.org/wiki/Image:Microwaved-DVD.jpg). In the end, I'm not sure if it was my reluctance to 'steal' the idea from Wiki or the fear of having my wife catch me putting a metal DVD in the microwave that ultimately dissuaded me. ;) I opted for this lichen from a rock in our back yard. It took all of a 10 minute break from my painting time to photograph and post it. 5 point deduction because I'm still not sure myself if lichen grows in the pattern of a natural fractal. Duncan Chesley http://www.pbase.com/shootin/image/68348233 The good news: My favorite image of the bunch. The bad news: One of my least favorite bunches. 5 bonus points for shooting what looks like a natural fractal to me. I like the colours and composition. Was this posed or natural? If natural, you caught a really good angle. N Lindan http://www.pbase.com/shootin/image/68354426 Very clever! I love the inclusion of the torn plastic. The staging of the 3 elements is very neat. I'm not fond of the large white patches in the blossom but I like the water drops. I think I'd also prefer a totally black background instead of the white specs all over it; especially in the upper right corner. I give "N" 10 bonus points of actually looking at the plastic under a microscope to very the fractal nature of the tear. Especially when considering the mandate, this is probably the 2nd place ribbon IMO. |

"Natural Fractals" ... Fractint ... an image of Henrik Engstrom's quaternion Mandelbrot set ... I'm inclined to think that natural fractals exist only in the mind of the beholder. Try the source: "The Fractal Geometry of Nature", B. Mandelbrot Also "The Algorithmic Geometry of Plants", Lindenmayer et. al. Fractals aren't the mathematical eyecandy - fractals are a property of nature that the eyecandy imitates. http://en.wikipedia.org/wiki/Fractal http://library.thinkquest.org/26242/full/ap/ap15.html But images of coastlines and fern leaves are boring, and so not much attention is given to them. The interesting point is that what appear to be very complex structures arise from very simple generating rules. -- Nicholas O.

If natural, you caught a really good angle. Thanks, Mardon. Be sure I'm saving up those bonus points. It's all natural. I was wandering around looking at the leaves on the trees near my home, when, unlike me, I looked down. Straight down. And, after a little camera orientation, snap. Cheers, DuncanC |

Thanks for your comments. Looks like I should have waited a few weeks for the leaves to fall from the central maple tree tree in the image so the branches would have been more obvious. I would have missed the colour show. I was looking for a central fractal theme surrounded by common diverse range of maple leaf sizes (not a fractal but close) and spectrum of colours, both consistent with the fractal theme to support the tree fractal. My Daddy was right stick to thirds or they won't see it. The image was cropped and re-sized not processed in any other way, softened by using an old Canon rebel film camera kit lens. w.. |

It has much the same form as the sprout from a potato http://www.inspection.gc.ca/english/.../potato21d.jpg http://research.cip.cgiar.org/potato...jpg_medium.jpg That looks a bit like roman cauliflower http://www.notthisorthat.com/sblog/u...auliflower.jpg That looks a bit like a Julia set [sort of a Mandelbrot set turned inside out] http://www.fractalartcontests.com/1998/images/258.gif So what do all these have to do with the equation for the Mandelbrot set: 2 Z = Z + Z n+1 n n Where Z is a complex number: x + yi, where i is the square root of -1 http://www.dgp.toronto.edu/~mjmcguff...mandelbrot.gif Which looks a bit like the egg case for a green Lynx spider. -- Nicholas O.

Al Denelsbeck http://www.pbase.com/shootin/image/68336564 How'd you do that? The lily pad looks like it's under the surface of the water but the droplets wouldn't float on water would they? Droplets wil float on water. In my kitchen I can let droplets float on the water. The droplets do look similar as in the picture. It seems logical that the droplets must be sitting on the leaf but it doesn't look that way to my eye. Intriguing! The veins are no You are probably correct that the leaf is under water and that the droplets float on the water. Soo you spotted this right. ben doubt fractal in nature, so do deduction there. To paraphrase our friend Bret, too bad "Elitechrome 100 Hates Lily Pads". "Elitechrome 100 LOVES those bubbles though." Too much washed out green for my taste. |

Wow, man, you're being hard on me... Chrome was not chrome, natural
fractal is not fractal... snif :-( I had the doubt with the chrome one, but I must disagree with this fractal thing. The leaves are not made up of oblong patterns; I was looking, in fact, the whole branch :-) If you pay attention the whole set of leaves has an oblong form (sort of, at least), similar to the oblong form that has each little branch on the sides of the main "trunk", and similar itself to the shape of every single leave... That's where I see the fractal, may be only in my eyes anyway... About the green and blue... I know some people that think like your mom, but I just don't see why blue and green are supposed to not going together, they are everywhere in nature and they feel fine there. I'm glad that you like the shadows and the lack of them, it was a risky bet for me, as I was not sure if I liked that effect, or not. So I chose to take the picture and decide later... And I'm still thinking :-) Thanks for your comments, I'll try to catch a no-doubt-one for the timing mandate for you ;-) -Quercus- P.S: I'm pushing my limits with english in these comments, so I hope I'm explaining myself in a correct way.
