Next, duplicate the blue layer once again. Set this duplicate to linear light at about 60% opacity. This will give the scene a stronger bluish tone. Actually, we don’t need the bluish tone this much. We will hide the bluish effect a bit more by masking some parts around the house, lawn, leaves, and cloud.
Give the duplicate layer a layer mask. With a very soft round brush, mask some areas mentioned before. We should vary the brush stroke and size when we want to mask some parts of the cloud using the setting like the ones below to define cloud texture. Here is the setting:
Here is the result of the layer mask should look like I created. The parts marked in the red areas are the masked parts stroked with the brush set before. The other parts are the ones stroked with a very soft round brush with clear brush control.
Here is the scene look like after masking.
Now give the scene new adjustment layers. Go to layer > new adjustment layer > brightness/contrast. Set this layer to normal at 60% opacity
Give another adjustment layer: curves. Set this layer to normal blending at 100% opacity.
Create a new layer (Shift+Ctrl+N) above all the other layers. Name this layer "color". On this layer, paint color texture like the one below. This texture is a combination of color dark blue #010b15 and greenish dark blue #041c28. Why do we choose this color combination? We will create gloomy misty nuance to the scene. This color combination will be a help to achieve this.
Set this layer to exclusion blending mode at 100% opacity.
Duplicate this layer two times. Set the first duplicate to exclusion blending at 100% opacity and the second one to multiply at 35% opacity. Give these two duplicates layer masks. Mask areas around the brightest cloud background and the topmost part of the roof.
Proceed to give another new adjustment layer above all the other layers. Go again to layer > new adjustment layers > brightness/contrast. Set this layer to normal blending at 80% opacity.
In this step, we will work on the cloud background. We should alter some cloud that looks uniform as indicated in the screenshot.
Open the cloud BG folder and create a new layer above all the other layers within the folder. Take a soft round brush tool (B) and set the setting of the brush as the ones done in previous step 11. With the color of #fcdgb1, paint the cloud as indicated in the screenshot.
We can lower the opacity of this layer if we stroke the cloud too strong.
Now we will give some color adjustment to the house layer. Select the house layer to be active on it. Go to layer > new adjustment layers > brightness/contrast. Give this adjustment layer a clipping mask.
Give this layer a layer mask and mask a few areas around the brightest cloud and windows. Finally set it to normal at about 54% opacity.
Give another adjustment layer with a clipping mask to the house. This time we will give it Hue/saturation layer.
Set this adjustment layer to normal at about 60% opacity.
Finally, create a new layer (Shift+Ctrl+N) with a clipping mask above the two adjustment layers. Take a very soft round brush. Set this brush to about 10-15% opacity and then paint soft white color on the edges of the upper roof to give it some highlight.
