Gradient use (for Beginners)

I was playing with some gradients and I found some interesting possibilities that I want to show you.
Here are my snippings

Gradient Tube Red

Flare Radial 101

Square Wood Frame

Radial Eyeball

Rounded Edge

I hope you like it.

How do you make the curved tube?

Thx Marcello! :tyspin

Tube Red gradient (radial) was used.

Holy cow, I never knew this was there!

1. gradient REDTUBE
2. click shape linear (default)and choose radial
3. click mouse ( dont release) from center bottom to the center

example

starting from the re-discovered tube gradient (thank Marcello!), creating a new one blue-green-red, playing with the it and a pattern...

Dinasset Thank you;
I think there is an antialiasing problem making the curves with the redtube gradient!

That's cool! :bigthup

I've improved the edges, making them look much smoother.

Of course I had to make one using my favorite hue.

Yes, Marcello, you are right, but imo that's true for any gradient which has a non-smoothed switch from one colour to another one; but this characteristics is on the opposite good for linear uses, so maybe we have to use different versions of this kind of gradients, one smoothed, one not smoothed

dinasset · **Posted:** Mon Jul 28, 2014 9:30 am **(#11)**

Wallace, did you smooth the gradient or the outcome after drawing the gradient?

I did the smoothing after.

OK, thanks

I was trying to put it on a path but it didn't work. I made a shape with the pen tool then went to paths and ran the tube gradient. Oh well, it is a nice feature, thanks Marcello.

Welcome! I run tube gradient after pen tool

looks nice Marcello but I thought it would come out like a tube. I will try it again.

did you use Gmic anisotropic?

No, I set cross-hair guides to find the center of my canvas, then made the red tube starting from the center. I used the ellipse selection tool, set to fixed and expand from center. To make a perfect circle and removed some of the outside edge. Duplicated the image and then removed the inner edge from the original.
I Gaussian blurred the duplicate layer and then applied color curves to the alpha channel, to refine the edge more. I then fuzzy selected the outside and feathered the selection, cleared this selection a few time until I liked what I was seeing. I also adjusted the brightness and contrast making it slightly darker.

Did you get all that?

Thanks Wallace but....I have to digest it piece by piece!
