Discussion Overview

The discussion revolves around techniques for accurately pinching and stretching an image in Photoshop, specifically focusing on achieving clean lines through various distortion methods. Participants explore different tools and approaches available in the software.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant expresses frustration with achieving the desired effect using Spherize, Liquify, and Pinch, indicating a need for clean lines.
  • Another participant suggests using the Warp tool, which may provide a solution, although one user notes they do not have access to this feature due to using an older version of Photoshop.
  • A different participant mentions the possibility of using MathMap for specific curves in the warp, emphasizing the importance of neatness in the pixel motion rather than freehand lines.
  • There is a reiteration of the need for neat lines in the distortion process, suggesting that precision is a key concern for the original poster.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best method to achieve the desired effect, with multiple suggestions and tools being proposed without agreement on their effectiveness.

Contextual Notes

Some participants mention limitations based on software versions, which may affect the availability of certain tools like Warp. There is also a focus on the aesthetic quality of the results, which remains subjective.

Who May Find This Useful

Users of Photoshop looking for advanced techniques in image manipulation, particularly those interested in distortion effects and maintaining clean lines in their work.

I've spent hours on this and can't get it right.

I want to pinch and stretch a box like in the image using some combination of distortions.

I've tried Spherize, Liquify and Pinch but no combination of them will produce it accurately (I need clean lines).

Help!

Have you tried
Edit, Transform, Warp yet?

I don't have warp. Probably because I'm running v6.0.

But thanks. That may well be the answer, and I know people at ex-work who do have up-to-date versions.
 
Also, if you have specific curves in mind for the warp, you can have MathMap do the pixel motion for you. you can even see the effects of coordinate changes like this.

It doesn't have to be specific, no, it just has to be neat. i.e. not freehand lines.
