People do take photographs of single atoms.  It requires a very colorful atom and a very bright flash, but both those things exist.  They&#x27;re not particularly interesting photographs: atoms are smaller than a light wavelength and they look like dots.  I&#x27;ve seen them before, although I couldn&#x27;t find one in a minute of Googling.  There are even movies, as described in this paper:<p><a href="http:&#x2F;&#x2F;dx.doi.org&#x2F;10.1063&#x2F;1.36788" rel="nofollow">http:&#x2F;&#x2F;dx.doi.org&#x2F;10.1063&#x2F;1.36788</a>
