Question - Can a fractal composition be created without software algorithmic fractals? So there's the challenge with a digital camera compose an organic fractal image. Where do ya start? A narrative about the creative process plus the creation of props and set design could take pages, so I will let brevity take reign. I cut an even slice of Naval Orange to act as an organic light filter. I placed the slice of fruit into a pre cut hole in the center of a black mat cardboard. Over this I placed an inverted ornately cut crystal salad bowel. The light source was a flashlight shining up from underneath the fruit. Focal distance was going to be less than 1 meter so a lens that can provide edge to edge sharp focus would be needed. I chose a 90mm 1:1 Macro. The make or break issue with this kind of set is alignment. Everything must be in perfect alignment with each other especially the camera. The camera must be plumb vertically and parallel to the horizontal plane of the subject. Be off by 2 degrees in any of these critical points and edge to edge focus is lost. The last consideration is DOF. I took a series of shots at different f/stops from f/2.8 to f/32, f/18 was best. I used all manual settings. I controlled white balance via the K scale. Because this take is near monochrome I adjusted the White Balance Shift to favor the orange band. This will make the dominate color show all its variations in hue. An unexpected bonus, the slice of fruit had a .75 cm hole in its center and that provided a nice burst effect in the center. This image is for the most part as the camera captured it. The only post processing consisted of minor adjustments to contrast and clarity in camera RAW. A Dyson's Sphere, imagine a star that has been completely encased inside an enormous metal sphere - Freeman Dyson did. He theorized that the inner surface area could support a civilization if the distance from the inner surface of the sphere where a sufficient distance from the star conditions for life could be maintained. Freeman Dyson further postulated that with access to 100% of the stars energy it is feasible that there would be enough energy to power a navigation system and perhaps even the ability to bend light rendering the entire sphere invisible. A hidden benefit of this kind of shot is at the end of shooting you get to eat the props, thanks for viewing ... B-)) Bob
