Oxford student uses ordinary camera to capture atom in prize-winning photograph

A British student used a regular camera and tripod to take a picture of a single atom that won a prize.
The single positively charged strontium atom was held almost still by electric fields. A blue-violet laser shone on the atom, making it absorb and re-emit light quickly enough for a regular camera to take a long exposure photo of it.
Mr. Nadlinger was able to get close enough to the atom, which was held between the tips of two needles about 2 millimeters apart, so that he could take a picture of it.

We can photograph an atom but still no clear pictures of Sasquatch.

Technically it is not a picture of the atom but re-emitted light. This is different from light reflected off an object which we normally think of as a picture of said object.
ETA let me try to explain this better:
Imagine taking a picture of a 1/2" diameter flashlight pointed directly at you from a mile away. It is unlikely it would appear on the image if the flashlight is off. Turn it on and if the flashlight is bright enough and the ambient light is low enough you will see it clearly. However, that is not a picture of the flashlight itself nor is this a picture of the atom itself, though it is fair to call it that casually. The laser is exciting electrons in the strontium atom by absorbing photons. When those atoms return to their natural energy state the photons are released and the camera pick them up. This happens very quickly like fluorescence and not slowly and randomly like phosphorescent material.
This is unlikely photoshop as the science is solid but it is also a leap to suggest that it is technically taking a picture of the atom as some (most?) would think of a picture. It is imaging the atom.

This world has no room for the enslaver of atoms.

Or, get a clear pic of 95% of liquor store robbers.

When I was in college I couldn’t even make a fake ID that looked right.

So thinking this through, isn’t it technically fair to say that this picture is just as “real” as a picture of a star in the night sky?
Granted, stars are self-luminous so that’s a difference. But when we take pictures of stars (and presumably when we view them with the naked eye) they appear much larger than they actually are due to diffraction. I would think the same thing is happening here.

I need to know it’s pronouns before forming an opinion.

So not a picture of an atom, just a picture of light reflecting from an atom.
