I had to fix some proportions of a sketch and thought PS has a number of tool from which one would serve my purpose but it turned out that all of them at the end did the same thing and unfortunately not the one thing I needed. Perhaps someone here can give me a hint?

Here is the problem:



Looking at the last pic you see that the eyes, ears and so on moved down but I want to leave them where they are along the vertical axis. I what to affect the image on the horizontal axis only. I tried "Edit->Transform->Perspective, Dissort and Skew" whereas Perspective was the only one of those tools, where I expected that kind of result.
I tried all three with the same offsets and the result was 100% identical. (What�s the point in having three functions for the same thing?) Anyway, does anyone know of a way to do it?

hey ... they are not the same Very Happy

But anyway... i tried a little and finaly got this result:

Make a selection of the part you want to change . I used the rectangle selection tool ( lol ... sorry my engl Smile ) and then EDIT -> TRANSFORM -> and than dissort. ( i guess thats almost the best result )

To make it look that way below you need to have ears and the outline of the face on separate layers.

You like the result? Questions? ask away

See: Yes this way is the closest you can get with these functions although the outline it self stiill gets transformed vertically and the rest of the face doesn�t get transformed horizontal at all. That brought me btw. to another idea that is even a little better (but only little): selecting one half of the outline and rotate it a little and then do the same for the other half. But it�s not perfect either cos you get some twist form the rotation in it.
However, thanks for the idea, it�s much better than what I had so far.

Rychan: strange isn�t it? Anyway thanks for trying.

Dude,

Simply transform it as such, then completely redraw the forehead to compensate. Its only a half elipse.

It's not that simply cheney. The transformation is doing more than just moving it down or shrinking the face, it is warping it.

Antx, the best result I got was simply by free transforming it and smushing it a little, then removing the top from the selection and smushing it some more, then removing more of the top and smushing it again, just over and over. It's tedious, but it ensures that the compression is happening only as you want it. It introduces aliasing if you don't do it carefully, also. It definitely seems there should be a way to warp selections without photoshop trying to treat it as a perspective transformation.

Here's what I managed to make.

I selected everything exept ears, eyes, nose, mouth and wrinkles that are attached to those parts, transformed it like the red line says, and then I moved the ears and rotated them a couple of degrees making them look right. I don't know if this is what you wanted to get, but at least I tried.

Thanks every one for your efforts. The main reason for this post was for me to see if someone knows an easy and general way to do such kind of transformation. As it seems there is no function or simple trick in PS to do this. Too bad cos it would be very handy.
This sketch was not the actual point here but more an example (I fixed it already by redrawing it cos I needed it precise). Dosn�t mean I don�t appreciate your efforts. I do, especially know that I found no general way. So thanks again.
