The title isn’t the best way to describe what I want to do, probably. I’ll try to explain better here. The relevant selection is below. You can see that inside the door is a bright white space, but it ends sharply below. I want to project a gradient light out below the door to hide that sharp edge and create a sort of implied floor, as if the light is shining onto the floor. This ad has what I’m talking about.
I’ve tried using the different light features on photoshop with little luck. If my difficulty getting across what I mean didn’t tip you off, I don’t have a whole lot of experience in photoshop. Is there a good way to pull this off and make it look natural?
Ok I am up to the challenge…
First we need to re-frame the image.
Now, What kind of floor do you need?
For an Ultra Glossy Floor, just copy your door, Skew it, mask it and add a gradient opacity.
The same for the frame of the door.
For a Satin floor, apply a gaussian blur to this same object and use some mesh fill to add the spilled light. Play with transparencies again. (There is a little gap between the rooms becouse of the gaussian blur)
For a Matt floor use a mesh fill. I actually did this with vectors but the process is the same.
You could add a texture, just adjust the perspective acordingly.
