Step 2
Duplicate the girl’s layer and go to Filter > Other > High Pass. Set the radius to 5, and change the blending mode to Vivid Light. Then go to Layer > Create Clipping Mask. This will increase the amount of detail.



Step 3
Add a layer at the top of the layer stack and go to Layer > Create Clipping Mask. Using a large soft black brush (B) paint over the girl. She will be almost touching the moon, so her face and arms should be shinier, while the bottom half of her body will be almost entirely in darkness.

To boost the contrast go to Layer > New Adjustment Layer > Gradient Map. Change the blending mode to Soft Light. This adjustment layer will also need to be a clipping mask.



Step 4
In a new layer, place the photo of the moon that you dowloaded at the start. Change the layer’s blending mode to Screen. Go to Image > Adjustment > Hue/Saturation, select Colorize, and make the moon bluer. Also go to Image > Adjustment > Brightness/Contrast. Increase the brightness to 54 and the contrast to 51.



Step 5
Fill a new layer with pink (ff80b6), then with a big soft brush, paint a light blur (61a5fb) where the moon will be. Change the layer’s blending mode to Soft Light. This layer will be on top of the others.
