METHOD 1
1. Open your image in Photoshop
2 (Optional - for photos with existing skies that are dark). Use the quick selection tool to remove the current sky. Select the quick selection icon, trace the foreground, then delete the background.
3. Place your sky overlay on top of this image as a layer. To do this, go to File --> Place or File --> Place Embedded
4. Once the overlay is placed, size your overlay to fit the skyline where it will be placed. Make sure the sizing overlaps onto the image. Then, click on the check mark to confirm this change.
5. If your image background is out of focus, blur your sky overlay to match by selecting Filter --> Blur. This will allow for a more realistic application. In this example, this action was not necessary.
6. In your layers panel, select the drop-down menu to the left of opacity and change the selection from Normal to Multiply.
7. Add a layer mask by going to Layer --> Layer Mask --> Hide all. Adding this mask with temporarily result in your sky overlay disappearing.
8. Select the Gradient Tool by selecting the appropriate icon on the left-hand icon menu. Make sure white is on top and black is on the bottom.
9. Using the gradient tool, drag the tool from the midline of the sky to the foreground horizon. If this lightens the area too much, select a soft brush set at a low opacity and paint over the area where you used the gradient tool to darken that area.

4. If your image background is out of focus, blur your sky overlay to match by selecting Filter --> Bur. This will allow for a more realistic application. In this example, this step was unnecessary.
5. Add a layer mask by going to Layer --> Layer Mask --> Hide all. Adding this mask with temporarily result in your sky overlay disappearing.
6. Select the layer mask. The layer box is black (remember: black conceals).
