I want to clarify the situation at 6:50 in terms of hyperfocal distance. When we calculate the hyperfocal distance (h) for 6:50, I am assuming the pixel size (c) is 1 mm, it turns out that h = 1.3 meters. So, does this mean that if the camera was focused at 1.3 meters, then the two back images will always be in focus? Thanks in advance!
