All cards
- Exposure basics: the three dialsAperture, shutter speed and ISO all change brightness. Each one also changes something else.
- Aperture and depth of fieldSmall f-numbers blur the background; big ones keep near and far sharp.
- Shutter speed: freeze or blurFast shutter speeds freeze waves and wings; slow ones turn water to silk.
- ND filters and long exposuresAn ND filter darkens the scene so the shutter can stay open longer.
- Long exposure seascapesRocks, waves and moving water on the coast, safely.
- PolarisersCut reflections and glare, deepen skies, and see into water.
- Low light and blue hourThe twenty minutes after sunset, and how to keep shooting as the light fades.
- Night sky and starsStarting settings for stars and the Milky Way without streaks.
- Sun stars and moon starsTurn the sun, the moon or a street light into a crisp star instead of a white blob.
- Sharp pictures: tripod and handheldWhere blur comes from, and simple ways to stop it.
- Wildlife autofocus and trackingKeep a moving animal sharp: focus modes, areas and drive.
- PanningFollow a moving subject with a slow shutter: sharp subject, streaked background.
