Can you please tell me which formula you used for this image?

Same formula for this?

For awhile I was playing around with generated/mutated formulas (using some software I wrote to do the mutation)... These two images were made with a couple of those. I never added any of those formulas t

I have been working for some time on ways to generate new fractal shapes, and also to be able to switch easily from Mandelbrot type (M-type) to Julia type (J-type). Here is what I’ve come up with.
UltraFractal formulas usually depend on two complex values, z and c. Usually z starts with the pixel value and changes throughout the iterations. Usually c does not change with the iterations; for

I have a square fractal, say 600x600 in the UF6 window. If I change it to 900x600 in the Image tab, the apparent magnification changes. I want to make it wider without changing the center or the apparent magnification. Is there a formula for changing Magnification in the Location tab that will do this?

It turns out that some combinations of formulas don't render properly unless Periodicity Checking is Off.

Example 2 also uses Power as the Initial Formula, but Two Formulas as the Main Formula. Formula #1 is a J-type Lambda, and Formula #2 is an M-type Lambda. Bailout is Divergence. Different bailout types give different results.

Hello,

This might be a dumb question, but I wasn't able to figure out where I can share parameters or formulas or other stuff, such that they make it into the public collections. Where do I upload or send them?

Best regards,
Phillip

A favorite coloring of mine in XaoS Fractal Zoomer is one called Biomorph. It changes shape depending on the bailout used. A low bailout such as 8 gives a stubby wider shape and a high bailout results in a more pointed, spike shape. See the pics here. Is there anything similar to this in Ultra Fractal? Jam2.ucl has biomorph and Outside Options under Fractint (Compatibility folder) also has bi

I've wanted to be able to add a vignette (a darkening of the corners and edges) to a fractal as is common in photo editing software, so finally I wrote one. It's Vignette in jlb.ucl.

It's a direct coloring, producing a layer with white at the center and grays to black at the edges. It is meant to be used as a top layer, with Multiply. Here are the parameters:

radius: inside this radius, t

I've added a revised version of QuadMirror to jlb.ulb. QuadMirror2 is a transform that takes a rectangular block from a fractal layer and tiles the fractal evenly with the block, mirroring it both horizontally and vertically.

The user specifies the number of blocks in each direction, the center of the original block, and where the original block goes (unmirrored). Because of the mirroring, t

I am currently on working on creating some fractals and animating them.

I had a question... I tried doing a fractal animation and it takes about 3-4 days to render and then at the end the log says "Error Saving image (error)

Is there another log where I can figure out what the exact error was?

According to the log it took close to 60 hours to finish so I do not want to go through it

Does Ultra Fractal offer any of the lambda fractal planes, as described in this link? I am aware of the inverse fractal mapping but was wondering if any of these others are possible as well?

I stumbled upon an amazing combination of variables: the standard Pixel formula with Gradient for family Outside coloring (sam.ucl) and the Inverse fractal plane mapping. How does such a transformation take place from a bunch of squares formed by the gradient to a beautiful rounded geometric pattern? I am baffled and pleasantly surprised!
