WHAT IS ASPECT RATIO?

• refers to the width of a picture (or screen) in relation to its height

• A 1:1 aspect ratio used to add to the simplicity of this image

A 4:3 format allows for capturing close foreground detail and leading lines to draw the eye into the image

A 6:4 aspect ratio is used here as no close foreground detail is being captured, yet the scene still benefits from a wide aspect

A wide and narrow 16:9 format was used here to emphasise the horizontal bands of colour

An ultra-wide 18:6 (3:1) aspect ratio was used to present this panorama of 7 stitched images, captured using a focal length of approx. 140 mm

From left to right: 6:4, 4:3, 5:4. Which one looks best?

WHAT IS PIXEL AND PIXEL DENSITY?

• “Pixel” is a minute area of illumination on a display screen, one of many from which an image is composed.

• “Pixel density” is the number of pixels a display can fit into a fixed distance.
