Is Double-Slit Experiment about measurement limitations or nature of the light?

Hi,

I was reading about Double-Slit experiment lately and Complementarity. Can we say that:  
The act of "**observing**” affects the electrons/photos but this doesn’t mean that the reality was not there. We don’t have a way to measure our system without changing the information in it. This is still more a **measurement limitation** for me than explaining the nature of the light.

"Observing" mean the the light interacts with macroscopic objects, such as the slit, barrier, and the screen. The experiment is about the nature of reality.  It's not a technological limit on our human measurements. A full discussion would include the concepts of local hidden-variables, and Bell's theorem (look them up).
