One theme per outing. Each sheet brings together the photographers who worked on it, the physics underneath and exercises to do with the camera that day. The sheets are written in Spanish.

Contrast

Light and shadow · form and texture · color · old and new · movement and stillness · portrait

Nine photographers who work with contrast: a reference work, analysis, physics and an exercise for the walk. Includes an interactive light lab. Walk route through A Coruña.

Metering light

What it measures · metering modes · exposure lock · zone system · histogram · without a meter · high and low key · movement · long exposures

What the light meter measures, metering modes, exposure lock on cameras and phones, the zone system and the histogram, with a lab for metering a street by touching the image.

Long exposure

The basic calculation · how long you can hold it · panning · emptying the street · aperture, ISO and filters · drawing with light

How much blur your subject leaves and how long you can hold the camera steady: from blur in pixels to shutter time, with panning, light trails, emptying the street, six reference photographers and an interactive lab.

Flash

The balance · guide number · sync · hard or soft · bouncing · daylight fill

How flash and ambient light share the exposure: guide number, sync, source size, bounce and daylight fill, with six reference photographers and an interactive flash bench.

The sheets are interactive and open on lab.rafaelvida.com, alongside the other tools. The sheets don’t reproduce the photographs they discuss, but each one links to the museum or archive where you can see them.
