What it can tell you

Flash within the usual sync rangeOn-Camera Direct Flash Fashion1/200 s at f/8 keeps the shutter where a normal flash covers the whole frame, and at ISO 100 it lets in almost no room light — the white wall is white because the flash hits it, and that one hard shadow behind him is the proof.Recipe: 1/200 s · f/8 – f/11 · ISO 100 · flash on
Dragging the shutterOn-Camera Direct Flash FashionAround 1/15 s the shutter stays open long enough for the room's own lamps to paint in — pan the camera and they streak — while the flash pop freezes his face and even the shadow it throws.Recipe: about 1/15 s · f/5.6 · ISO 400 · flash turned down to match
Available light, no flashRembrandt Window Portrait1/125 s at f/2.8 – f/4 and ISO 400 is set for the window-lit side of his face, so the concrete wall behind him falls about a stop under and the window itself goes white. No flash: the shutter, aperture and ISO move everything together.Recipe: 1/125 s · f/2.8 – f/4 · ISO 400 · no flash
