Test Cards and MTFs (or: how to measure resolution)

Test cards were an essential tool in the analog television era because they allowed you to properly calibrate the colors, geometry and contrast, and allowed you to measure the resolution of cameras and televisions. But how do you measure resolution? This video tries to explain what the camera system is actually trying to reproduce: contrast changes. These can be measured using line pairs, and are characterized by the Modulation Transfer Function (MTF). The resolution is typically defined as 10% of the MTF, because that is around where the human eye cannot tell apart any contrast changes anymore🎥🎞️ #photography #optics #television #contrast #physics #science #signal #engineering #MTF #camera #images #imageprocessing #gain #amplitude #resolution #HD

When i read MTF i thought something else lol

yeeeep. Same.

Call me weird or whatever, but I'd still prefer to keep 1 or 2, even if just for the sake of archives. Something not useful now doesn't mean it won't be useful later. Especially with many people (gamers more precisely) focusing and framerate and quality, who know?
