Learning Photography Course — 8. Photographing the World
Module 8 of the Learning Photography Course. Seven modules built a camera you understand. This one takes it outside and points it at the world — portrait, landscape, street, wildlife, macro, night, sport, architecture and events.
The idea that runs through the whole module: every genre is one hard constraint plus taste. A face is only a few centimetres deep. A landscape needs everything sharp at once. The street moment will not wait. Wildlife is far away. Macro depth of field is measured in millimetres. The night is short of light and the stars move. Sport is fast. Buildings need straight lines. Name the constraint and the settings mostly choose themselves — using five questions that work for any genre: what must be sharp, what is moving, how much light is there, how close can I get, and what do I owe the subject.
Worked numbers, with the assumptions stated: an 85 mm lens at f/1.4 focused at a metre and a half is sharp through about 26 mm in total, which is why you focus on the nearer eye. Hyperfocal distance for a 24 mm lens at f/11 is about 1.75 m. Zone focusing a 28 mm lens at f/8 puts everything from about 1.6 m to infinity in focus before the camera is raised. A ten-stop ND filter turns 1/60 s into about 17 seconds. At 1:1 magnification f/8 behaves like f/16, and depth of field is about a millimetre.
The night sky: why the old 500 rule allows visible star trails on a modern sensor, and the NPF rule devised by Frédéric Michaud of the Société Astronomique du Havre in 2010 — about 9.5 seconds against the 500 rule's 21 for the same 24 mm lens. The Bortle dark-sky scale, published by John Bortle in Sky & Telescope in February 2001.
And the law, quoted from the primary source and dated. The Metropolitan Police's own guidance that no permit is needed to photograph in public places and that officers cannot delete images. The ICO's statement that pictures taken for your own enjoyment are outside the UK GDPR — and why commercial use ends that. The Wildlife and Countryside Act 1981 on disturbing Schedule 1 birds at the nest, with 'recklessly' added in 2000. Legal is not the same as fair, and the module says so.

Quoted for: no permit needed to photograph in public places; officers cannot delete digital images or destroy film; Section 43 viewing power; Section 58A guidance. Stated as the Met's own position.
- Information Commissioner's Office, 'A guide to the data protection exemptions', page dated 8 May 2025, read 17 September 2026. Quoted for the purely personal or household activity exemption and its example of 'taking pictures for your own enjoyment'.
- Wildlife and Countryside Act 1981, Schedule 1 disturbance offence, and the addition of 'recklessly' by the Countryside and Rights of Way Act 2000 — READ THROUGH the RSPB's summary of the Act and Nature TTL's licence guide, whose offence wording agrees; not read in legislation.gov.uk today. Penalties and the licensing body in each nation are NOT narrated.
- Société Astronomique du Havre, 'La règle NPF', sahavre.fr — read 17 September 2026. Rule devised by Frédéric Michaud, 2010; simplified form t = (35N + 30p) / f used, and said to be the simplified form.

- CALCULATIONS, NOT CITATIONS: hyperfocal distance, depth of field, effective macro aperture and ND filter factors are worked from the standard formulas with a 0.03 mm full-frame circle of confusion stated on screen.
- CONVENTIONS, NOT MEASUREMENTS: shutter speeds for birds in flight, walking people, freezing and panning are given as the starting points photographers use, and labelled as such on screen.
- NOT ASSERTED AS LAW: that some countries give people a right over their own image. France is named as the example usually given, and the viewer is told to check before travelling.
