After that, let’s rename the layer to “haze 1”.
Let’s create another rectangle because we would need to darken the area on the top. Activate the Rectangle tool (U) and use the following color settings:

After that right click on the layer to bring up the contextual menu and when the menu pops up, click on Rasterize. We will need to do this to make the layer available for editing or so we could apply filters to this layer. Now that the layer has been Rasterized, go to Filter > Blur > Motion Blur from the Menu bar and input the following settings:
Our image should now be similar to this:

We’ve filled up the ceiling with water, we’ve changed the color tone of the room and now we’ll need to change our floor. Let’s open Calm Water stwberrystk; activate the Marquee tool (M) and left-click and drag a selection area around the ocean and drag that region to our canvas using the Move tool (V). After it has been moved to our canvas, rename that layer to “water floor”.

Now let’s activate the Transform tool (Ctrl/Cmd + T) because we would need the help of our Distort tool to fit our Calm Water stwberrystk stock image into the floor. With the Distort tool activated, move the squares to fit the floor. Once again, so you won’t have a hard time transforming the stock image, reduce its Opacity to 50%. See image below:

Next, change its Blending mode to Soft Light and its Opacity to 50%. We’ll also need to change its color tone to blend with the rest of the images; with the “water floor” layer selected, hit Ctrl + B to adjust the Color Balance and input the settings below:
Let’s check and see how the image looks right now:
