The first reading really was a crash course for me, it became evident even just trying to purchase my 35mm camera how very little I knew about cameras and how they work. I’ve build pinhole cameras in my childhood, and owned/operated a digital for most of my adult life, but I never really understood a lot of the features or limitations of what I was working with. Reading this not only helped me understand how to operate cameras most efficiently , but how cameras operate on the inside. I’ve also linked a couple of cool tricks that these chapters reminded me of.  Check them out if you get a chance.
