A quantum experiment can be set up such that the whole experiment can be carried out without the experimenter being present. During the experiment, measurements are made, again without the experimenter being present, and data is collected. Afterwards, the experimenter can read the results of the detectors, etc. and thus obtain the data that is subsequently used to develop a theory. The only time a conscious being is needed is to set up the experiment and afterwards learn the results of the recorded data. Note that measuring devices force the quantum system into the eigenvalues being measured. The latter is what the collapse of the wave function means.

Question

As I recall from my reading the collapse of the wave function in the
Copenhagen Interpretation or splitting off of another universe in the
MWI, occurs when a quantum event like:
1.radioactive decay occurs
2.the position/momentum of an electron or other small particle is measured
and a conscious individual is aware of the result.

What about the case where a conscious individual observes a source of
light? The observed photons typically are generated when an electron
falls from one energy state to another. Is such photon generation a
collapse of the wave function? What other things cause the collapse of
the wave function or splitting off of another universe?

Does the collapse of the wave function always require a conscious
individual in the loop?
