Here’s how the Levels adjustment can be used to transform the colours in an image
To make an image look as though it was taken at dawn, add the Levels adjustment by going to Layers>New Adjustment Layer>Levels. Hit OK in the pop-up dialog.
Inside Levels change the drop-down list of colours from RGB to Red. Any changes will only target the parts of the image in the Red Channel.
Push inwards the white marker until the highlights tint red. Move the middle marker to the left to add a red glow to the image.
Change the blend mode of the adjustment to Color. If you need to make the image lighter, add the Brightness/Contrast adjustment and increase the Brightness slider slightly.
