Taking a photo requires focusing and pressing the shutter button, snapping multiple shots in case some are blurry, and immediately checking the captured photo so adjustments can be made. To hold the camera still, keep elbows together against the chest, left hand under the lens, lean into the camera holding it tight, and keep legs open. It's also important to snap extra shots for quality and avoid errors, then check the pictures and save the best while deleting others to save memory space.
