Rainbow by Skybase

Good that you have been able and wanted to share and upload this filter to the library.

This is weird, unusual, curious, beautiful, artistic and original idea.

I have seen how it works and has some good settings and options and can be made more things than only beautiful unusual artistic swirls

Thanks for uploading this

The only possibly negative thing I see is the name at least it could have been Rainbow Swirls

What I mean with more than swirls is this shown here

For example take the default preset of Gradient Circles by Skybase



and then using the settings shown you can get this also interesting effect without the swirl part

And now let´s use really the filter with the swirls using the same gradient circle preset of above and the settings shown to get this golden beautiful swirls

And using same source as above and using the first default presets as base and then modify the setting as shown you can get this beautiful green rainbow that looks as it was made with with cross polarized light photography

And then using preset 3 using same source as first post, and slightly modify settings, you get this ghostly color swirls

And from the one above here, I have ONLY changed the Gradient to value 1 and got this beautiful and artistic green rainbow like swirls

Here I am using some plain color rainbow stripes with rainbow filter will give you this kind of fluid ink like artistic result

Awesome filter Skybase. Just beautiful work.

When opening the filter and click on the checkbox, I have seen that this makes plain bar colors instead of the gradient bars, but then on the result, I do not see any difference, so sorry that I could not discover yet, what is this for.

Yup that's it. Nothing more. It's not so obvious until you crank iteration counts higher.

Probably will make a version that hosts a different method of dealing with gradients. Something more flexible than the way it's implemented currently.

I found something interesting, I have loaded an image with transparent background and found that this filter makes a curious and good effect with this one, and all the transparent is converted to black, and all the swirls will only appear in the non-transparent areas, so this combined with the good black, can get beautiful effects.

This alpha mask (transparent background shown in the above 2 posts) can be also useful to make some kind of frames

Then thought to make another experiment with black square frame, and instead of just one big frame on the borders, why not have some more inside?

So I have made the following in Photoshop:

Have taken this black frame above here and reduced it in width and put it more inside, then I duplicated the layer and reduced the square inward, and then I duplicated again and reduced more, then after having the 3 layers, I selected the layer with the smallest square and then go to Filter--> Filter Forge 4

Here is the result that I have described

And then after using the same one as above here, and reducing the Swirl scale, I got this other one

Both of this have the Gradient Input value 1

In the construction process the filter just uses a completely black background layer separate from the stuff you input. So no matter what you feed in, the result will be on a black output. The library version features a simple additive output. In order to use this on any other layer, I recommend blending the layer using linear dodge (add) or screen as well as other additive blend modes.

Just to tease... in the original non-library version there were multiple blending mechanisms. For example geometric mean mode with bias.

Ooooh I like those last two! I've been playing around with this filter and I found I got some interesting effects by adding stretch and angle sliders to the distortion component.

angelize, I answered you privately via email.

I'll probably talk about the technical stuff more openly about how stuff works once I'm done with the project itself.

And as Skybase have suggested, you can also use blend modes to modify the result

I have used here the blend modes in Photoshop with a copy of the layer, but it will be the same with any other software that uses blend modes or even with FF itself.

Here I have duplicated the original transparent layer, and then I have used "normal" blend mode on the first, and "Linear Light" blend mode on the second and have modified the Hue range a little

UNMULTIPLY - DIRECT BLACK BACKGROUND REMOVAL

I have just found that there is another filter that removes black background that does NOT NEED to be modified to use it, is directly from the FF Library.

Remove "Black Element" from the image

It works very well and gives great result, so you do not need to modify the Peel off white filter.

REMOVING BLACK BACKGROUND TO BE ABLE TO MIX SWIRLS IN DIFFERENT LAYERS

After trying these filters to remove the black background I had the idea that once it has the transparent background, it could be used to duplicate the layer and then mix the copies of the result using blend modes, and then you can choose the background that you want in the first layer.

I have used as result from this filter, the one I have already made shown in a post above



This is how I have done it to get the final result shown at the end based on this image shown here

1 - Use this Rainbow filter in Photoshop to the get the result you want

2 - Remove the black with the Unmultiply filter or Peel off white (converted to black) be aware that it is applied to a unlocked layer.

3 - Enlarge the canvas width with so when rotating or modifying the result it will not be lost some parts of it outside of the canvas

4 - Put a new layer as background and fill it with what you want

5 - Duplicate the rainbow filter result, that is now transparent, as many times as you want, I have made 4 copies

6 - Use blend modes to mix the layers, I have used Linear Light for the first layer as the background is black, and then the others layers use Screen blend mode

7 - Rotate, modify and/or change the position of the layers and experiment of what you can do with them.

8 - You can modify also the layers together or individually, you can change the hue, or any other thing to get different effects. I applied a Hue adjustment layer so it changed all the colors from the original result

9 - Erase any unwanted parts of any of the layers that could not fit well

Here is the final result I have done with 4 copies of the image shown here above and rotated in different angles and changing the hue range to all the layers

Skybase Let me keep it brief: it's possible to allow alpha channels to happen at the core level. I rebuilt the filter from scratch just to get a fresh perspective on it.

You did not have to bother about this unless you wanted to do it yourself, because I did not suggest to do it, as it can be easily be done with the combination of the two filters.

And I have done it only after the angelize question, and found that removing the black could be useful for more things.

But as it seems that you have already done it and thanks to Betis is possible, would be good to know how it is done.

Good news that seems that you are making a new upd ate to the filter, but I would suggest to take your time to make it right and as you want it, and with only the things you want to have it.

I also like the original filter, so I think it must be possible to make the same things as before, or if this is not possible maybe you could do a different version, and if you do want to have a new version the alternative is to make a copy of the original as a backup and then have the new one.

Sorry to ask, why "Outline Amount" is called this way? because I do not see that it has effect only in the outline, and is a global thing, for me and from the tests I have done is more like a brightness or darkening se tting

Skybase Now it's got colors.

Sorry that I do not know what you mean with this, as before you could already choose 5 gradient colors, and choose the gradient input 2

so what is different now with the new update?
