Horizontal amd Vertical scale in Displace filter...

[samifox]

Hi

I've read Adove documentions about Horizontal amd Vertical scale in Displace filter but i got confused [confused] .

when their both are 100% the effect of the displacment map is 128 max, but what if one of them is under 100?

of my experments i see that the scale effect the undefined areas and not the effect amount, dows anybodt make an order in my brain please?

Somebody say, Displace? [slick]

Channels

Math 2

Quickie:

50% = max 64 pixels
100% = max 128 pixels
200% = max 256 pixels
400% = max 512 pixels

Starting to see a pattern yet?
And this isn't taking into account the brightness values in the D-Map, hence all are "max"imum.

Stroker is onto something!

For a very long, but very complete tutorial on the Displacer filter, lookie here

Naaa, Stroker's the Man for Displace info. [excited]

Samifox be sure to checkout Stroker's tutorials on this filter. It'll open your eyes and mind to it more.

Steve and I definitely have our different approaches to Displace. On the surface, his uses are more for real life applications (he's a photographer and does that kind of work). Me, I'm a goofball and write about what interests me.

Beneath the surface, we have *very* different approaches on a fundamental level. Read these two pages and see if you can see the difference:
Displace Filter, Introductory Examples
Circle Grads
The difference between those two pages was a major break through for me. Once I got away from the "push" idea, my head exploded with all sorts of goodness. It was an epiphany of grand scale.

There is also a difference in how we work. Steve works on seperate channels, while I do a lot of work on the composite. This is reflected very well in some of my techniques.

I don't know if mine is better over-all, but I do pride myself on two points:
1) Over a dozen pages explaining the fundamentals and how it all fits together.
2) "Advanced" techniques with Ad-Layers and Layer Mask.

The ironic thing is: it took Steve's Curve tutorial to push me in the right direction. Once I added Curves, my head exploded again - another epiphany of grand scale.

OT: Last week I added Heat Waves.
