Turn day into night in Photoshop

03. Curve dodge

Our grass is still shrouded in darkness, so now we can add some soft, glowing moonlight using another Curves layer and a mask. This is sometimes known as Curve Dodge: it's simply a Curves layer with the mid-tones brought right up, creating a brightening effect, and a hide-all mask applied. We can now paint in this brightening effect using a soft white brush on the mask layer.

04. Balance the colouring

The advantage of a Curve Dodge layer is that we can now balance the colouring of this effect. I'm adding some warmth by bringing the red curve up and also bringing the blue curve up to make sure it still harmonises with the moonlight.

To soften this effect, hide the brush strokes and, to add a bit of glow, we can add some blur to our mask. With the mask selected, go to Gaussian Blur, in the Blur menu and select a high value of around 50 to 100px.

05. Add the moon

To add a bit more of a night feel, we're going to paste in a shot of the moon and a shot of some clouds, both taken against a black, night-sky background.

Once pasted in, and resized and positioned appropriately with the Free Transform tool, simply change the blending mode of both layers to Screen. You can use a mask on either of these layers to hide them wherever you need to.
