The rock is hiding under the bed.

If you want to get serious about understanding Displace, start at the very beginning of Technical Slop and go through it slowly. Displace takes several things into consideration and can be a mess to untangle and understand at first. When I had my first epiphany, it took me 2 days to understand it. Then it took me 2 years to write about it.

Start at the beginning and take it slow.

One of the best ways is to read Power Distort. One chunk at a time and do the exercise. Do not move on to the next chunk and exercise until you understand.

Two quick notes:
1. A D-Map does indeed have to be a PSD and the composite thumbnail preview option has to be turned on when saved. The composite preview is what Displace reads.
2. The Interpolation setting in Options will have an affect. The chosen interpolation method is what is used to sample the D-Map when Stretch to Fit is turned on.

If I get in the mood, I might come out of retirement for a bit and post some stuff specific to this thread.

Thanks Stroker

Yes thatís what I thought. Power Distort1 Here I come.

Iíve got some great ideas for brush strokes that will need this lot.
I donít know if itís possible yet. So I need to know what can be done.

After that Iíve booked 10 Days on Byros Beach with Biker Chic (Thatís 1.43 Weeks Byro)

Thanks Ken,

This makes things a whole lot clearer. I noticed in the final pics though that there is quite a bit of distortion (other than the desired one). Is there a way to reduce this?

Goose.

I'm Glad this made things a bit clearer. (It certainly did for me)

Yes you are right. I did not expect to have to distort by 300% to get this. And there are some diagonal lines in my results which should not be there.
I am going to spend some time here
http://tech-slop.serveit.org/powerdistort/index.shtml

If I find some answers then Iíll be back.


In the meantime there is an easier answer to your initial question if you just need to get the job done.


1) Open Transform.jpg
2) Filter > Distort > Spherize - Amount 100% - Mode > Horizontal Only > OK

You will need to fiddle with the position of the bit you need to transform


Thatís it.
This will give you what you wanted.

Hope this Helps.


Ken

Ha!

I had never though to pull down the menu in the spherize filter. I hadn't seen you could isolate the horizontal and vertical! That's perfect! Thank you Ken.
