Imaging in Chaotica - Part 1Today, lets explore the Chaotica Imaging widget.tatasz
As the name says, brightness controls how bright your image is. The effect of brightness will also depend on 1/gamma setting (for high values of 1/gamma, brightness will have less impact on the image).
You can either type in values, click on the up and down arrows or click on the arrows and drag.
Brightness effect on a gnarl:
People usually call it just Gamma. Increasing Gamma will basically make your fractal flame more solid.
Low Gamma may create some excessively bright spots.
High Gamma may introduce noise and artifacts (areas that would be almost transparent with lower gamma values will become visible). Also, may make the image look flat by reducing the contrast.
Look how increasing Gamma affects the gnarl:

Math and Programming for Fractal ArtistsArtist's Toolboxtatasz
Math and programming may look as scary subjects sometimes, but it is quite a useful tool when you are creating algorithmic art. After all, it is algorithic art
Understanding how your favourite software works
Of course, you do not need to be able to create a brand new fancy perfect fractal software from blank Still, some basic knowledge of how things work may be useful. Understanding the math behind a formula or a transformation can help you to find some cooler settings for it, or combine it sucessfully with other things. Being able to read some code usually helps, since there are very few tutorials and explanations on how things actually work (and not "add this, and then more around those sliders).
Creating your own custom plugins / formulas
Sometimes, the existing things just don't do what you want. It could be just a tiny little change in a formula. With some basic programmi
Imaging in Chaotica - Part 2: Response CurvesToday, a bit more about imaging in Chaotica.tatasz
Mostly curves <3
Lets take a closer look at curves:
WHAT do the CURVES DO?
Curves basically re-map the brightness values: for example, make bright pixels brighter or darker by just adjusting the curve.
The horizontal axis is the original brightness (before editing), while the vertical is the new brightness. The tones are distributed as follows: dark tones closer to the origin, and light tones far from the origin.
The image above shows the curves before any changes. See that before and after values are equal, since no changes were made yet.
Basically, if you drag a node up, lets say, it will make the corresponding tones brighter. For example, dragging up the top node (light tones) will make highlights brighter, and dragging down the bottom node (dark tones) will darken the dark areas. On t
Response Curves Tricks and TipsA few tips and tricks on how to use curves to make your images pretty.tatasz
Disclaimer: the images below are not models of perfect curves, but just rough examples of some settings i find helpful.
Also, those are not any close to all possible magic things you can do with curves. Explore ^^
Add contrast to a light Image
Lets say you have a light image with few contrast.
Moving down the dark tones and maybe midtones nodes of the Overall curve will add contrast to it:
Make a dark image brighter
We may also want to do it the other way around: make a very dark image a bit brighter.
Had to go a bit crazy to lighten this up:
green Lights and purple shadows
You can also use the Green curve to add
since obviously it became a problem to share and consume resources in a once free and open-spaced fractal community lately, I've taken down any of my resources off deviantART.
But don't sweat, it's actually been on the roadmap for a long while since my deviantART profile is, in future, only about artworks.
Here is where you can find the resources I keep up instead:
If you want to learn when I upload a plugin or something else nifty, you can follow my Twitter.
PS: Yes, the download page is supposed to look like this. I just filled it with links but didn't add a style or anything
PS2: I think I'll also post updates on my activity feed here on DA since many people don't seem to use Twitter or have reasons not to do so.
No Time :(i am swamped with school and work...i played in apo today for a bit but didn't have time to render so i thought i would put this here so anyone who wants to tweak this canSuicideBySafetyPin
