How To Fake Sunlight In a Dark Room

Realistically, there are a lot of different ways someone could approach this. In this tutorial, I’ll outline the way I would approach this technique.
The first thing I would do is duplicate the layer, so that I’d have two copies of the image. One the 2nd copy (the highest layer in order) I would goto Filter > Render > Lighting Effects, and then use these settings: Light Type: Spot Light, Negative: 60, Focus: 50. I would also set the light source as the center of the window, and the area effected as the entire image.

The end result will look a bit to bright and doesn’t convey the sense that the sunlight is coming directly through the window. This is where our underlying layer comes into play. Using the Polygonal Lasso Tool on our top layer, select the area you would like to have the sun shine through. Once selected, goto Select > Inverse, and then hit the Delete key.


Now we’re left with a very bad looking image. Ha ha. We’ll fix that by using the Filter > Blur > Motion Blur filter on the top most layer (make sure you’ve unselected everything first) Change the angle to -43 degrees and the pixels to 98.

Next, we’re going to change some of the blending options on this layer. We’ll reduce the Opacity to 28%, and add a white Outer Glow.

This gives our final image:

well i think this looks ok , but there is one big mistake , the beam is beaming to the wrong side
It’s a good one. Very helpful.
The tutorial is okay, but the light is not realistic in the picture you have chosen. If you look at the trees in the backyard, then you’ll notice that the light comes from left, since there’s shadows on the right of the trees, and therefore the sunlight beam should move from left to right and not right to left.
It doesn’t look realistic due to the simple matter of the lake outside. You can clearly tell by looking out the window that the sun is shining from the top left and therefore should the light entering the window be horizonally flipped…
well it dos’nt matter if it look realistic this tutorial is about how you do it not how to make it realistic give him some credits for taking the time to make it so you can learn it to then you can do it and make it look realistic in your work… good work
agree with jon, give the guy some slack. some guys always just see the half empty glass
Greetings from Florida! I came across your blog posting after searching for fake degree and your post on hPhotoshop – Free Photoshop Tutorials makes an interesting read. Thanks for sharing. I will research more next Sunday when I have the day off.
the light come from right or left hand. Anyway, it’s useful for me. Thank.
