Fractal
visionaries:
Here's another fractal from one of my Mytest formulas. I'm
getting hung up on this series of formulas, which I wrote a while back
and then forgot. But there's no cause to worry, the formulas
make
good fractals.
Today's fractal is another quickie. When I first saw it, I
thought of a transparent stained glass window illuminated from behind
by the last rays of the setting sun.
The appearance of depth and illumination from within is something I
always strive for in my pictures. Unfortunately,
the effect
is quite difficult to reproduce on a CMYK color printer. The
RGB
of the screen just doesn't translate very well to CMYK. The
new
6-color and 7-color printers do somewhat better, but there's just no
way that reflected light viewing will ever equal direct RGB
viewing. The cones of the eye are sensitive to red, green and
blue, and you can't fight nature. This is why fractals
displayed
as huge expensive transparencies look so impressive.
For tomorrow's fractal I haven't the slightest idea. I'll
just
have to wait and see what's on the screen when the time comes.
