Turn the overall atmosphere of the image supplied (day_for_night_01.tiff) as close as you can get to dusk/night

• Use adjustment layers
• Darker but not just dark. Assume moon as overall light source. Blue-ish cast
• Usually more contrast. Lower saturation in color.
• If the scene does not have enough of a color you want to amplify, you may want to add it using "solid color" adjustment layer. Play around with the blending mode and the opacity

Once you are done, group the adjustment layers by selecting all the adjustment layers and then

Layer -> Group Layers

Name the group "dark_atmosphere" so that it looks like this:

We want to deal with the light area under the lamp posts. Since we made the overall picture dark, it is going to be difficult (or lower in quality) if we tried to turn that area lighter after turning it darker. (More operation in photoshop, more destructive.)

So we are going to duplicate the original image (the highest quality) onto the top layer. (Layer -> Duplicate Layer)



Then make a layer mask for the "BrightPhoto copy" layer. Paint the layermask in so that the mask reveals the "BrightPhoto copy" where there should be light cast from the lamp posts so that it looks like the image below. (Don't worry about the lamp post itself. We will deal with it later).

In terms of the mask, it may be easier to think if you thought of the mask as "hiding" areas of the "BrightPhoto copy" so the layers underneath it is revlealed.



Using adjustment layers and turning them into clipping masks (so that it only applies to "Bright Photo copy"), turn the lighter area yellow/contrastier/harsher.

This is the same idea as the previous example.



Idea:
1. Make an adjustment layer that turns areas more yellow/lighter
2. I would draw on the layermask revealing that layer usign a Wacom tablet pen
