Iterations sets a limit on how many times the pattern equation is
applied to each pixel. In general, the greater the number of iterations,
the greater the variety of colors and detail is possible in the image.
But this comes at a cost because the greater the number of iterations,
the greater the number of calculations may be required by your computer,
so the time it takes to generate an image can become very long.
The range of iterations is from 1 to 9999. Usually a small number like
50 or so is enough for great results. But sometimes only a larger number
will do, and moving the slider can become a problem for large numbers.
See range for details about how the range
control can help make large control values easier to work with.
Here's an example of how much difference even a small change in the
number of iterations can make. The image on the left was created with
the same settings as GoldenBrot in
the fractal gallery.
