April-May Challenges - See New Journal!Over the next two months we will again be running two challenges. You can submit up to four entries in total in any combination to the challenges. All entries must be uploaded on or after April 1st.
1. The Julia+fBm Formula Challenge - Closed! Please see
April 10th - UPDATE - Please read:
We are getting the impression that the objective of this challenge has perhaps not been stated clearly enough...
- For this challenge we need you to explore the formula parameters of the chosen formula: "Julia+fBm", which is from dmj.ufm.
- This formula has a number of distortion and noise parameters which will alter the fractal image by distorting it with fBm effects.
- We want you to play with any and all of these parameters to see what this formula can do.
- We need to see these effects in your submitted images.
- You must not use transforms or mappings, and please try to avoid fBm effects coming from elsewhere e.g the Outs

Only members may submit images.
2 submissions per day
Only fractals made with Ultra Fractal (any version though) are accepted!
Please make sure that you state that your work is created in Ultra Fractal (or UF) in your artist's description!
In the Fractal Manipulations folder, please make sure that at least 2/3rds of the picture consists of work done in Ultra Fractal!
Please only post your own works. Stolen images will be reported immediately.
If you were awarded a DD, suggest it as a fav, we have saved our favourites for your awarded pieces
Quality filtering applies: if your deviation falls below the regulations, the piece will be declined.
Possible reasons for decline are as follows:
Works that are basically identical to one already accepted, but colored differently.
The work is much too basic (one layer or so resembling one of the starter parameters that come with UF).
The work is too similar to an original work where parameters have been supplied, thus displaying lack of creativity.
The work is full of artifacts due to poor attention being given to quality when resizing. This may occur when a very large image is uploaded and dA's resizing facility is relied upon for display purposes. It is always best to reduce the display size in your favourite editor first. A nice size is between 800px to 1000px across the width, and around 750px high.
The use of the dA watermark may be an issue due to its intrusiveness. If this is the case we will most likely decline the work;
The display image is too small so that we cannot properly see the details. dA's minimum size is not enough. We suggest not less than 500px on the shortest side as a minimum.
The use of copyrighted images in any way will be declined.
If you have any questions about the rules, feel free to note the Group
Cheers! Your UF-Artists Team.

A few remarks about rendering UF fractals.This is for beginners or those who find that UF doesn't render sharp enough fractals.A few remarks about rendering UF fractals. by CopperColour
I'm not an expert with Ultra Fractal but I've learned a few things about rendering from advice I've received.
When I used Fractal Explorer I learned that the anti-aliasing tool just made my fractals blurry but no anti-aliasing gave jagged edges.
I was advised to render a very large size without anti-aliasing, for example at least 4000px per inch for the longest side, and to reduce it afterwards in an editing programme.
This mades the fractal smooth and reasonably clear.
So that is what I do now with my UF renders. If there are a lot of small details I render even bigger.
I render as .bmp for a good quality and reduce to 1600px and save as .jpeg which uploads quicker.
I'm told that .png is better.
I also set the resolution to 720. I don't know how far this affects the render.
I find that I lose details and clarity with any method so I use contrast and sharpening tools in post-work.
Making an easy UF fractal animation.This is a short and easy method to make an animated fractal. It uses UF’s gradient tool.Making an easy UF fractal animation. by CopperColour
The Extended Edition UF makes animations, otherwise you will need a programme that makes .gif animations such as Photoscape or GIMP.
I think some versions of Photoshop make them too.
PhotoScape makes a small size but GIMP makes a nice large size. e.g. 800X800px
The basic idea is to render many fractals with progressive and small changes in the gradient.
With just one layer they will render quickly.
Be careful not to move the fractal or the animation will show a sudden jump.
I find that sometimes my cursor moving across the screen causes the image to pan.
It's best to work with the History window open and you can see if it does and correct it.
So prepare a new parameter folder in UF to receive your images and another to receive the renders.
First, to make it easy, make a fractal with one layer and Drawing Method > Multipass Linear for a nice appearance
