    Then you must have one hell of a remote shutter release :)

    Beautiful lines and tones in #2. Number 4 gives me a bit of vertigo.

    Is it just me or are they all OOF?

    Aside from them all being blurry, #3 is the least "snap-shot" looking. However, I think that one is the most OOF.

    No Josh, it's a product of really crappy interpolation, I think. There's visible aliasing too.

    Maybe I am just really tired, but I'm not sure what you mean. Will you please assist my brain fart? :confused:

    Interpolation is whenever a program has to re-interpret the pixels and assign new values. This happens whenever you rotate an image at anything other than 90º angles, or resize an image (both enlarging and making it smaller). Aliasing is when straight edges look jagged and uneven, and that's very evident in the above images. You'll find this page very helpful.

    As an aside, as a general rule, it's important to avoid interpolation as much as possible. If you must interpolate an image, do it as few times as possible; in the case of rotating images, this would mean going back to the original if the rotation is off, instead of rotating the already rotated image again.

    You are probably right cause I did shrink the size in order to make the file small enough so I can put it on the web. How do you avoid interpolation if you want to decrease the size of an image?
