  • Overly-rotated Ducky

    This is more interesting than useful, but it does demonstrate the dangers of rotation.

    I was fiddling around (as I tend to do) and transformed the ducky.tif image by 15 degrees. Then I wrote an action to rotate it all the way around in 15 degree increments. Then I wrote an action that ran the first action 10 times. Then I wrote another action that ran that action several times (I lost count).

    So anyway, here's what ducky looks like if rotated around about 100 times in 15 degree increments.

    By the way, if you want to try this at home, use transform, not rotate canvas. I initially tried rotating canvas but ducky just kept getting smaller and smaller until you couldn't even tell who he was.

    Here I took the peppers.jpg image that comes with Photoshop and subjected it to 3x the rotation that ducky got.

      Could be useful as a starting point if anyone ever gets asked to design a maze based on a photograph...

      I rather like the effect on ducky, actually, although I can't think what I'd use it for...

        Here are the peppers rotated in 360 1-degree increments.

        By the way, I tried other interpolation methods with varied results. Bilinear just blurred, but nearest-neighbor gave a neat diffused effect.

          Hello, Doug! I followed the link
          What interpolation method did you use for the first one? Bicubic Sharper, or was it before PSCS, thus bicubic?

          By the way, I tried other interpolation methods with varied results. Bilinear just blurred, but nearest-neighbor gave a neat diffused effect.
          Again, this is why we need to be able to select the interpolation method in the option bar when using tranform...

            That was posted right at the end of the beta program, so I doubt I was using CS (I try not to post stuff here that can't be replicated with the current version).

            I suspect bicubic sharper would make things even worse (better?) due to the additional edge effect of the sharpening.
