Problem: I haven't heard yet about a Photo with 4 Autors. That should be tracked back to the guy who hold the cam. --Itu (talk) 23:36, 25 January 2012 (UTC)

This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: cropped, brightened. The original can be found here: see file history.

This image has currency in it to indicate scale.

Using coins for scale is discouraged as it will require people unfamiliar with them to look up the dimensions or guess, both of which defeat the purpose of the object in the first place. Coins can also reinforce a geographical bias, and some coins' designs are copyrighted.

Ideally, a photograph should include a ruler with the subject (example) or an added scale marking. SI ("metric") units are the most commonly used worldwide (see meter and centimeter).
