I read instruction manuals. I always have. When I open something up for the first time, I read the instruction manual. When I am putting something together, I read the instructions. In fact, when my hubby and I were engaged, we got a stool as a wedding shower gift and I wanted to put it together. I took it out of the box and laid out all the pieces and unfolded the instructions and made sure I following the instructions step by step. My hubby (fiance at the time) didn’t think I needed the instructions and proceeded to tell me how to put it together. We ended up in a fight. Haha!
This video is a series of diagrams and drawings that are simple to understand. Its like an instruction manual on Depth of Field. Really, really easy to understand and it’s like a lightbulb went off in my head after watching this.
