Adding Depth to a Sketchup Drawing on Photoshop

This drawing was taken from my class files. It was a ready drawing that was completed on sketchup, and my job was to add depth to it.  

First, start with opening the file on Sketchup. 

Go to styles from window, 

Edit from styles and export as 2d graphic

Adding fog

Take three pix to photoshop; t

he colored, the fogy, and the lines

Start with the colored and make it a normal layer

Then add the lines on top of it

and make it multiplay

Then make the colored one a layer mask

Then paste the foggy into the layer mask

Click while pressing Alt and paste the foggy one. 

Turn off the unused layer. Then use the lens.

Open the blur box for the colored layer

Source is layer mask

Goal is to make the end of the room blurry and have the piece of the furniture stand out

Change the blur focal distance

After doing the blur disable the layer mask


Then u can edit further with other tools like BURN

Then add lights to windows through selecting them and add white
