I guess the biggest jump for a beginner photographer is to learn the camera settings and learn the variables like ISO, EV, shutterspeed, aperture. For instance, aperture controls the depth of field (ex. f. 1.8 is shallow depth of field- used in portrait and on f.16 everything will be in focus- landscape). If I take a sport picture with slow shutterspeed, the action will be blurred. If I use high shutterspeed, the action will be frozen by the camera.
