the coin, being the most versatile, is should be the obvious winner.

Which coin would you use?

    If I had to pick one coin without knowing what the small object is I would probably lean towards a US dime or more likely the nickel (or a similar coin from another currency). The silver-like color works with more things than copper (penny) or "gold" (US $1 coin). And the nickel is thicker, which would help it stand out more in lower angle camera shots than the dime. Quarters can be a bit too big (ditto for the US $1 coin). An ancient coin would likely draw too much attention to itself (focus is supposed to be on the small object) and people would be less familiar with it, so it would be less useful to indicate size.

    Problems with the others:

    • Pen(cil) and Keyboard: Less flexibility than the coin. Implies certain settings (office, on a desk).
    • Ruler: Little artistic value. Will likely draw attention from the small object. Looks out of place outside.
    • Credit card: Everyone will be looking at the number.... ;-)
    • CD and Floppy: Less flexible and may date the photo -- e.g. maybe use a DVD or BD today instead?
    • Door key: One of the better choices, but still less flexible than the coin (key in grass or sand?)
    • Thimble: One of the better choices, but may draw attention away from the small object and looks a bit out of place outdoors.
    • Drinking glass: Too big.
    • Human hand or finger: varies in size too much.

    Anyway, the short version is that coins offer the most flexibility for generating a photo that is both functional and artistic.

      The problem with coins is that they vary widely in size within any currency, and are very country/trading area specific/limited.

      The beauty of a CD--for which I would include DVDs & Blue-rays, is they are universal as much as anything is; have a very standardized size, and more than one point of accurate reference--the outer diameter, the inner diameter, the writing around the centre; the thickness.

      From an artistic point of view, the reflective rear surface opens up any number of possibilities.

      Hm. This is a silly poll, and yet, we're taking it seriously. It's that coders instinct to want to solve the problem I guess :)

        It would be interesting to find out what the average diameter is for modern day coins. Anything too large is now handled via paper currency (or plastic), so I do not think the variance is anything to be too concerned about. Though if I knew the average diameter, I would probably pick a coin that was very close to that size. Good point on your part!

        The biggest factor for me, even to the point of overriding the variance size concerns you raised, is that the coin is the only item on that list that can be used virtually anywhere without looking too out of place.

        Regarding CDs/DVDs/BDs, I think there is still the issue of potentially being too big, and thus distracting from the small object that should be the main focus of the photograph. And of course the location issue. The size can be partially mitigated by using a Mini-CD, but not the location.

        Lol!! I've been doing a lot of 3D graphics work lately (as a hobby), so I think I'm in "how would I create a scene as described in the title?" mode. It's almost like a render challenge. (^_^)

        Update: As a side note, if more than one coin can be used then I think that also pretty much negates the size variance issue.

    It would be fun to try the "coins" used on Yap. Some are twelve feet in diameter.

    not "which", "whos" - and the answer to that is "yours"
