When I was younger I thought about taking up Cinematography as a profession.  
I did too! Cinematography really involves the science and art of motion pictures.
There really is so much to it, it is more like an art than anything at all.
Yeah but it involves a lot of technology like electronic image sensors.
Now it does, that is for sure!  It did when it first started too tho.  Imagine making a silent movie interesting enough to watch!
That sounds pretty cool. Also a lens is what is normally used.
All the work with the lighting and effects must be so much fun!
Yeah, and also using a camera with an electronic image sensor to make videos.
