>Bubble chamber photograph of an electron knocked out of a hydrogen atom by $K^-$ particle The curly line was produced by an electron that was struck by one of twelve passing beam particles in a liquid hydrogen bubble chamber. It curves in an applied magnetic field and loses energy rapidly, spiralling inwards.
Electrons were first "seen" in cloud chambers, but bubble chambers really "see" elementary particles.
The process is the following, involving zillions of photon exchanges and photons to create the event and to be able to see it with our eyes.
1) The primary generation of an electron: A $K^-$ particle ( the beam coming in) hits an electron in the hydrogen of the bubble chamber and a sufficiently energetic electron comes out. All the dots making the tracks visible are very small energy similar scatters, that end up in ionizing the hydrogen in the way, and a bubble forms ( due to the supercooled hydrogen, another story).
2)the electron starts bending in the magnetic field, so its momentum can be measured. ( the $K^-$ is also bending but because it has very high energy it cannot be seen by eye, only careful measurements over distance)
3)the electron loses energy with continuous small scatters spiraling inwards
All these reactions are electromagnetic with exchanges of off mass shell photons.
4) a picture is taken and developed by using electronic coincidense for the passing of the beam
5) photons from the environment hit our eye and show the electron path.
Thus we both "see" at second hand the electron, and all the other particles in the link. Photons are always involved.
