Ego - zero rotation bug fixed and uploaded. I gotta handed to the creativity of the members. Really nice work.

A new twist on the Twist. Rotate your image in slices. (The Original twist makes the image unrecognizable.)

Pseudo Greyscale from Pseudo-Random Noise. The plugin takes your color image and de-saturates it by shifting the pixel colors randomly. I included a Span and Offset control to adjust the hue and intensity of the de-saturation, Sorry no video instructions - this ones too easy to use.

I agree Ego- it's now in Colors Menu

How to make a faux reflection pond with the plug-in: http://youtu.be/1zIqTkgiIbw

It's only slow when the size of the image doesn't match the size of the map. When it does match the transformation is instant. I wasn't sure whether to call it a bump map or a displacement map. Since both refer to 3D shaders. Perhaps Displacement would be better. Update: I've changed the name and included the recommendation to use same size image and map , I also modified the Youtube tutorial to reflect the changes. Thanks for your help Ego.

The grayscale of an image copied to the Clipboard modifies your image's pixel locations in 3D space. Endless varieties of can be achieved. Effect->Distort->TRs Displacement Map 3D Version 2.0 added a bunch of fun creative features. Highligth and Shadow Light Source Positioning Color Adjustment Alpha Transparency.

Technorobbo's Fish Eye 2.2 v2.2 adds color cast to highlight and specular control v2.1 fixes a bug in the highlight V2.0 adds shadow, rotation and specular highlight It's not a Bulge Filter.

Gaussian Blur + Compared to Edge Fader I think I classify Edge Fader as a vignetting tool. (Note to self: enough with the horses)

I'm gonna have to check that one out. Does it work on horses?

That's a possibillity. I thought that since I'm replacing all colors and messing with the alpha, it really wasn't a color filter of sorts. I don't know. Let me put it out to a vote. What do people think the "natural fit" category is?

Yes, this Plug-in actually fades the Alpha inwards from the edges up to 255 Pixels . (Version 1.3 fixes an artifact left at top if selection. Available now.) BoltBaits Feather uses a GaussianBlur on the edges, Here's how he explained it in his tutorial.

CMY Ghost is a way to mess with the Color and Alpha create wild effects. Version 1.1- is now in the Color Menu. Instrunction Link: http://youtu.be/Vd2WPemHc3g Program reposted on 3:23 PM Sunday, June 9, 2013 (UTC) CycleHSV allows you to do a per pixel cycle the colors space with Saturation and Brightness as well as Hue. The values roll over with out clamping (a hue of 361 = 1, a saturation of 101 =1 etc). This leads to interesting Posterization effects.

Ego Here's a YouTube video I made to explain better Edit : see original Post

Yellowman, I took your advice and moved it to the selection menu. Good Suggestion - I wasn't sure I could put it there but obviously I can.I replaced the download in the original post.
