Kirsty Fairweather Photography

Photographs are made with a range of equipment and settings, and the technical choices behind an image often go unnoticed by the viewer. The details below relate to a single frame captured on 21 March 2023.

Camera and lens

The photograph was taken with a Canon EOS 5D Mark III, a full-frame digital SLR. The lens was set to a focal length of 43 mm, a slightly wider-than-standard view that sits close to how the human eye perceives a scene. Its maximum aperture is f/2.8.

Exposure settings

• Exposure: 1/160 second at f/18
• ISO speed: 320
• Exposure mode: Manual
• Exposure programme: Manual
• Exposure bias: 0 EV
• Metering mode: Spot
• Flash: Not fired, compulsory mode

The combination of a relatively fast shutter speed and a narrow aperture suggests a scene with good available light, where depth of field and sharpness were priorities. Spot metering means the exposure was judged from a small, specific area of the frame rather than an average across the whole image.
