Dreamy Scene

In this tutorial we are going to create a beautiful scene that works well with fairy stories. You can also use it in some posters which require dreamy effects as well

Let's start our tutorial!
Step 1: Download the original image or open your own image. Duplicate our image by pressing Ctrl-J. Before applying some effect on it, we should increase its contrast by going to Image>Adjustments>Brightness/Contrast and increase the Contrast slider to 100%

Step 2: Change its blending mode to Multiply to make the picture sharper

Step 3: Press Ctrl-Shift-Alt-E to create a new layer which is the result of its underlying layers. Next we will add a nice sky to it. You can cut out the sky from this picture

Place it on our castle picture. Make sure the sky covers most of our image

Step 4: Change the sky layer's blending mode to Multiply to apply the new sky to our image. This mode works well because we had a nearly white sky in the original image (notice that Multiply mode eliminates white areas and retains darker areas)

Step 5: Use the Eraser Tool with a soft brush (0% hardness) to erase the junction of two layers

Step 6: In this step we will add a light source to our image, a cold sun!
Create a new layer and use the Rectangular Marquee Tool to create a small selection area on the sky

then fill it with black

Go to Filter>Render>Lens Flare and choose 105mm Prime light source

and change its blending mode to Overlay

Finally use the Eraser tool with a soft brush to wipe out the edges. Now we had a beautiful Sun!

Step 7: Now we will add a dreamy effect to our image. Press Ctrl-Alt-Shift-E again to create a composited layer and press Ctrl-J to duplicate it. Go to Filter>Blur>Gaussian Blur and set a Radius of 1.5 pixels

then change the blending mode of this layer to Overlay

Finally, you can use the Eraser tool to reveal some dark areas on the castle. Let's have a look at the final result again:

This is the end of the tutorial. I hope this lesson will useful for you!
