This lesson assumes you're already comfortable shooting in Manual. Here, exposure becomes a deliberate creative tool, not just a matter of getting a "correct" reading.
Bracketing means shooting the same scene at multiple exposure levels — one standard, one under, one over — either to guarantee a usable frame in tricky light, or to blend them later into a single image with more dynamic range than one exposure could capture. Most cameras have an auto-bracketing function that fires this sequence automatically.
Expose to the Right (ETTR) is a RAW technique based on how sensors actually record light: more real data sits in the brightest third of the histogram than the darkest third, so shadows pulled up in editing show more noise than highlights pulled down. ETTR means intentionally exposing as bright as possible without clipping highlights, then correcting exposure down in editing — cleaner results, especially in low light. It requires trusting your histogram over how the image looks on-screen.
The Zone System, simplified: rather than the full historical eleven-zone framework, the practical version is this — before shooting, decide what in your scene should render as true black, true white, and mid-gray, and meter deliberately for those points instead of letting the camera average the whole frame.
For high-contrast scenes specifically, meter for whatever matters most (usually your subject, letting the background clip if needed), use graduated ND filters outdoors, or accept that some scenes are genuinely better served by two blended exposures than a single-frame solution.
