Background

This is early February on a Winter photo tour. The beach was littered with this attractive blue ice. The glacier chunks had beautiful scalloped textures.

Focal lengthOn the ice beach I often chose my focal length according to the action in the sky. With such strong colours all over the sky, 24mm was a no-brainer.

Aperture

Because of how close I was to the foreground ice (see “Composition”) f/9 was chosen because sharpness is only important on the foreground ice. From memory, my lens was set to f/11 hyperfocal (favouring the foreground – because the background is only about colour and shape).
