I am trying to generate my own zoom with Kalles Fraktaler, but am disappointed with the default palette.  I am wondering if there are any palettes available for download which I could try loading into the program. Or can I pull the palette out of one of the kfr files in the gallery supplied with the program?  Right now almost all images are about as interesting as looking at a beach of multicolored sand.

I do see a section in the color selection selection which says "Palette Waves", which I suspect is what I want to duplicate some of the more interesting effects I see on the deep zooms on YouTube.  I am clueless though how to use that function for generating, what are the period and start numbers like dimension 11.

Thanks,

Marshall

This should probably be moved to "Fractalforums Fractal Software Fractal Programs Discussion, Help, & Support Kalles Fraktaler".

Use "divide iteration" to get rid of the noise effect (increase to get slower color change). For a smooth 1024 color palette and distance log/analytic coloring best value I find is around 0.01. For iteration coloring with random palette it may need to be as high as 500 or so.

You can edit the colors, for example set "Number of key colors" to 4 and then play with the colors. You can load any example and save the palette.
Inf. waves and palette waves are not stored in the palette files, but in the kfr, which is a bit confusing.

Never used "palette waves". Infinite waves I use, for example set HSV = 7,5,3, DE logarithhmic or analytic, divide iters 1. Then play with "color offsets" to get interesting colorings. Larger HSV numbers give slower color variations.

Note that not all coloring modes are supported in KF movie maker and you have to reenter all the settings except the color palette.

It might be possible to edit the .kfr file (eg, remove coordinates, fractal type, etc) and rename it to .kfp to load waves in the palette dialog without resetting location.  But I'm not sure, that part of the code isn't something I've looked at.

Thanks, after playing around with it a while I found I can load a kfr file, then in the colors selection save a kfp file, thus saving the palette.

I have updated my Kalles Fraktaler palette files on Media Fire http://www.mediafire.com/file/4o8h1fop68h17hj/KFPalettes.zip.
There are 1,147 palette files!
Mostly they are generated from spreadsheet data and copy pasted into a .kfp file by NotePad+.
NotePad+ has nice search replace features to change TAB separators and CR LF line endings into commas that the .kfp file uses.

On the file naming convention used a file name such as
"p512bcgwmryk.kfp" is a 512 colour palette a 3bit colour cube sorted into Blue, Cyan, Green, White, Magenta, Red and yellow groups, then sub sorted within these groups to get a smooth changes in colour.
Most files will have a striping ending "p512bcgwmrykof8.kfp" shifts each 2nd colour 8 places.
"p512bcgwmrykpm4816"  is a more complex striping, the 2nd colour is shifted 4 paces, the 4th 8 places, the 6th 4 places and the 8th 16 places and so on.
"p512X2bcgwyrmkof32" duplicates the 512 colour palette into light and dark halves.
"p1024bmwmbcgyrk" the "bm" stands for bit mix a more satisfactory way of sampling the 8 bit colour cube into 1024 colours.
There are a few other oddball palettes, "LenaSoderburg.kfp" is a palette that is a 32x32 low resolution version of the famous "Lena" picture use in early image processing development.
