Turn out the lights on a daytime scene using the power of Photoshop’s adjustment layers

final

1. Turn day into night

Step1

Go to File>Open and choose the file you want to edit. Go to Layer>New Adjustment Layer>Brightness And Contrast. Set the Brightness to -150 and the Contrast to -50. Next, go to Layer>New Adjustment Layer>Levels. Set the Highlight Output level to 100.

2. Reduce the saturation

Step2

Because we have darkened the image to simulate the night, we’ll also need to reduce the saturation. Go to Layer>New Adjustment Layer>Hue/ Saturation and set the Saturation to -60. Select the Red channel and set the Saturation to -60. Finally, select the Blue channel and set the Saturation to -40.

3. Select the sky

Step3

Turn off the adjustment layers and select the background layer. Go to Select>Colour range. Click once in the sky to select the Blue and set the Fuzziness to 80, then click OK. Go to Select>Save Selection and name this selection ‘Sky’. Turn the adjustment layers back on.

4. Insert stars

Step4

Go to File>Place Embedded and select a stock image of some stars. Resize and position the stars over the sky and to go Select>Load Selection. In the channel menu choose the Sky channel. Go to Layer>Layer Mask>Reveal selection. Select a soft brush and clean up the mask.

5. Add the moon

Step5

Go to File>Place Embedded and select a stock image of the moon. Resize and position the moon behind the buildings. Hit Opt/Alt, click on the stars layer mask and drag up to the moon layer to copy it. Set the blend mode to Screen and see the mask of stars from behind the moon.

6. Make street lights

Step6

Create a new layer (Cmd/Ctrl+Shift+N) and name it ‘Street lights’. Set the Opacity to 75%. With a small soft brush choose an off-white colour (yellow or blue) and paint hot spots on the street lights. Make the brush smaller for the light further away from the camera.

7. Create a glow

Step7

Create a another new layer and name this layer ‘Street lights glow’. Set the blend mode to Color Dodge. Choose a dark yellow or orange colour and with a soft brush, paint the glow onto the street. Duplicate this layer to make the glow stronger.

8. Add details

Step8

Once again, create a new layer and name this layer ‘Street lights details’. Using the same method as the previous step, paint small details onto the edges of the signposts and buildings, anywhere where the light from the street lights would shine on the objects in the street.

9. Light the windows

Step9

Go to Layer>New Fill Layer>Solid colour. Set blend mode to Color Dodge, choose a colour – we used #888273. Invert the layer mask (Cmd/Ctrl+I) and paint one of the windows black. Duplicate layer (Cmd/ Ctrl+J), select the layer mask. Go to Gaussian Blur and set Radius to 10.

10. Add more lights

Step10

Repeat step 9 on a number of windows. Try to vary the colour from window to window. You can also vary the blur amount and even paint in the glow yourself, using a soft brush on the colour fill’s layer mask.

11. Add car light streaks

Step11

Go to File>Place Embedded and choose an image of some white car lights. Resize and position the lights on the left side of the road and set the blend mode to Screen. Go to Layer>Layer Mask>Hide all. Now with a soft white brush, paint the lights back in and fade them out in the distance.

12. Include car lights

Step12

Duplicate the white car lights layer. Go to Filter>Blur>Gaussian Blur and set the amount to 10px. Go to File>Place Embedded and choose an image of some red car lights. Resize and position this layer on the right side of the road and set the blend mode again to Screen.

13. Warp the lights

Step13

Go to Filter>Liquify (for Elements go to Filter>Distort>Liquify). Warp and distort the red lights to match the road. Go to Layer>Layer Mask>Hide all and with a soft white brush, paint the red light back in.

14. Blend in the lights

Step14

Go to Layer>New Adjustment Layer>Levels. Set the Shadow Input level to 35, this will help the lights blend in more. Go to Layer>Create Clipping Mask (Opt/Alt+Cmd/Ctrl+G) so it only affects the car lights layer.

15. Inject a glow

Step15

Go to the Hue/Saturation settings, set Saturation to -20. Create a new Clipping Mask. Duplicate the red lights and adjustment layers (Cmd/Ctrl+J), reapply the clipping mask if needed. Select the red lights layer, go to Gaussian Blur, set Radius to 10.

16. Colour adjustments

Step16

Create a new layer (Shift+Cmd/Ctrl+N) and name it Noise. In the mode box select Soft Light and tick the box to fill the layer with 50% Gray. Go to Filter >Noise>Add noise, enter 3%. Go to Layer>New Adjustment Layer>Level, select the Blue channel and enter 10 in the Shadow Output Level.

17. Day to night

Step17

Select the first adjustment layer that is above the background layer and Shift click the top layer to select all of the them together. Select Layer>Group Layers (Cmd/Ctrl+G). Then go to Layer>Layer Mask>Reveal all. Select the Gradient tool and painting from black to white, add a Gradient to the layer mask and finish off the effect.
