Daylight through the day

One light source, entirely different results depending on the hour. The pattern is predictable, which means it can be planned for.

Dawn and dusk: the golden hour

When the sun is low, its light passes through much more atmosphere. That scatters out the blue, leaving warm colour temperature, and softens the light considerably.

It also arrives from the side, which reveals texture and shape rather than flattening them.

golden hour is the most flattering light most photographers ever get for free. Its drawback is that it changes quickly and does not wait.

Before dawn and after dusk: the blue hour

Once the sun is below the horizon, the light comes from the whole sky rather than from the sun. It is even, shadowless and strongly blue.

blue hour is the best time to photograph a city, because artificial lights are lit and still balance against the sky. Half an hour later they overwhelm it.

There is very little of it, and it needs a tripod or a high iso.

Midday

The sun overhead, small in the sky and unfiltered. Hard light, high contrast, shadows pooling directly beneath things.

It is genuinely difficult for faces — eye sockets go dark, noses cast shadows onto mouths. It is good for graphic shadows, for architecture, and for anything where contrast is the subject.

Overcast

Cloud turns the entire sky into one enormous soft source. Shadows almost disappear, contrast drops, and colours saturate.

Unhelpful for drama; excellent for portraits, for detail, and for anything in a forest, where direct sun would produce a mess of blown highlights and black shadows.

Planning

Time	Light	Suits
Blue hour	Even, blue, dim	Cities, water, skylines
Golden hour	Warm, soft, low	Portraits, landscape, texture
Midday	Hard, overhead	Graphic shadows, shade, interiors
Overcast	Soft, even	Portraits, detail, woodland

The useful habit is checking sunrise and sunset times for where you are, and arriving before rather than during.

Key takeaways

• Low sun is warm and soft because its light travels through more atmosphere.
• Blue hour is short, even and ideal for cities.
• Midday is hard and unflattering for faces; open shade is the answer.
• Overcast is a giant soft source, poor for drama and excellent for detail.
