Blue Hour

The blue hour lasts only a few minutes. The sun has just dropped below the horizon, artificial light starts to glow, and the sky takes on that deep, cool colour that simply does not exist during the day. The Blue Hour preset was made for exactly that moment. Not to exaggerate it, but to hold on to what is actually there.

Technically, the preset shifts the shadows toward cool blue while preserving warmth in the midtones where artificial light or the last traces of sunlight are still present. The contrast is solid but not harsh. Highlights are pulled back slightly so that streetlamps and reflections in water retain detail. The tone curve adds quiet depth without making the image look processed or forced. Colours are saturated but never loud.

The preset works best with coastal scenes, harbours, and urban water reflections. Think of a pier at dusk, waves breaking against rocks while the sky still holds some light, or a fishing port where the lanterns have just come on. Wet city streets with shop windows glowing also respond well, because the blue tones and orange lights in the frame create a natural contrast that the preset brings forward.

You reach for Blue Hour when you want to hold on to the feeling of that brief window of time. Not as a technical exercise, but as an experience. When you are standing on location in the evening and you know this is it, this preset gives you a strong starting point that needs little extra work. It can also be useful for overcast daytime shots where you want to suggest an evening atmosphere, though it will need more manual adjustment in those cases.

A practical tip: set your colour temperature slightly warmer than usual in Lightroom before applying the preset. The blue hour already has cool tones by nature, and the preset reinforces that. Starting around 4800 to 5200 Kelvin lets the warm light sources in your frame glow against the blue background without the overall image feeling too cold.
