And the aperture is f36! I've thought about stacking, and probably should given the overwhelming majority of my subject matter doesn't move. This might be a good approach with composites using fewer pictures. Not sure sure what it is, maybe someone could explain the physics to me. But these macro composites hate tripods...the images won't align...probably why focus consistency is an issue here. I understand that more successful panoramic images have a very particular point of rotation that is likely to be ahead of the tripod mount. But if I'm shooting macro, I need vertical pivot as well...maybe I'm wrong? Perhaps, at this scale (1:2 - 1:3 as an estimate), I'm able to get away with slightly raising the camera vertically and pivoting less. Could this reduce distortion that prevents image alignment?

HERE <https://lh5.googleusercontent.com/-FlsH3yu7gWk/Uq70-3jaH2I/AAAAAAAADYo/GNSPckkjCDA/w1280-h793-no/Lizard.jpg> is a perfect example of one composed using a tripod. None of these pictures aligned, so I did it manually. Bracketing the focus would have been a tremendous plus here as I could have gotten the feet, tail, and head a lot sharper. I thought it came out well, but now I'm getting some better perspective.

Trevor why are you limited by dof? Changing the plan of focus would solve that problem. You can also do focus brackets I'd the previous isn't an option

    No need to qualify at all! My approach to these images is that,
    maybe someday, I'll print them full size. having patches of poor
    exposure is not an option. I am limited with DoF given they are
    all macro images. It's a testament to the challenge with the
    pictures. Thanks for the feedback, I'll look into it!

        Fascinating subject composition. But again, and I am tired of
        this, the subject is not in focus!!!! This subject suggests
        that many topics were used to create the final addition.
        Multiple frames layered one onto the other which can create
        some amazing images, but especially in sharpening. In
        Astronomy, it is the technique commonly used to gain more
        sharpness of a planet or moon. Thousands of images are stacked
        to create one very sharp image.

        I do like the image.

        To qualify, I am using a 45in HD monitor. If all of these
        subjects are indeed sharp to everyone else, then I apologize.
        But my monitor does render a lot of these images as too soft
        for qualification.

        But not all of them.
