A List Apart
"I'm never disappointed by Photojojo." -- Dave Johnson
Scene opens to solar winds gently blowing intergalactic tumbleweeds past the open porch door. An eerie quiet blankets the solar system.
We don’t know about you, but ever since those astronomers kicked Pluto out of the party, we’ve been feeling mighty lonely over here on planet Earth.
But wait! We’ve just the solution: Our pal Dirk wrote up a tutorial that shows you how to turn any panorama or landscape photograph into a full-fledged planet!
Best of all, once you’ve selected an image to work with, the process takes only 5 minutes. (Launching your new planet into solar orbit may take a bit longer.)
There are special moments in the life of any photographer that suddenly change his view of his hobby (or profession). For me, those moments included:
To make a long story short: The “Polar Panorama Effect” is one of my favorite ways to process photos into unique pieces of art. It takes a panoramic (or landscape) photo and uses the Polar Coordinates filter of Photoshop CS or The Gimp to create a circular image that seems to wrap the panorama around a planet.
Looks cool, and it’s easy to do! Let’s get started.
Selecting a Source Photo for Your Planet
When selecting a photo to start with you should keep the following things in mind:
We’re going to go through two examples: the first uses a simple panorama, the second a landscape shot that we’ll crop before proceeding.
Starting Simple: Planet San Francisco
It’s simplest to work with a 360 degree panorama, so let’s start with this panorama shot of San Francisco taken from the Coit Tower:
Step 1: Resize and Rotate
Select Image>Image Size from the menus. Uncheck ‘Constrain Proporties’ and set the “height” to the same value as your “width”. Next, rotate the image 180 degrees. (Image>Rotate Canvas>180)
You should end up with something like the image to the right.
Step 2: Apply the Polar Filter
Choose Filter > Distort > Polar Coordinates from the menus and in the resulting dialog box, select the “Rectangular to Polar” setting.
(If you’re using The Gimp the command is Filters > Distorts > Polar Coords.)
As you can see we’re 90% of the way there!:
Easy cheesy, right? Now for some finishing touches…
Step 3: Rotate and clean up
The rest is just a little digital darkroom work: Rotate the planet to your liking, adjust the contrast and colors, clean up the sky and the edges where the left and right border of the image came together. (The clone stamp and healing brush may be handy here.) That’s it, we’re done!
More Advanced: Planet Venice
Planets work best when created using panoramas, but for this second example we’ll use the following landscape photo of San Girgio Maggiore Island in Venice. Islands are especially well-suited for planetization because the left and right edges of the images are easy to match up–you only have to make sure the horizon is level.
Crop and Straighten
Because we’re not starting with a 360 degree panorama, we’ll need to do some extra work before we can follow the steps above.
First we’ve gotta crop and straighten the image to make the horizon absolutely horizontal. Using the cropping tool of PhotoShop we can do both in one step:
First, we must ensure that our crop selection is parallel to the horizon. Choose the crop tool and select a flat rectangular area of the photo. Move the cursor just outside of an edge of the selected area so that the cursor changes to two arrows pointing left and up. Click the mouse button and you can rotate the cropped area.
By moving the top border of your selection to the horizon of the photo you can inspect the rotation closely. Move and rotate the crop selection until the top border and your horizon are parallel, but don’t crop your photo yet.
Now we want to make sure the left and the right borders of the image fit together. Look for areas on the right and the left where the buildings have the same height:
Move the right and left borders of your selection so that the edges will match up. Finally, adjust the top and bottom of your selection so your waterline is roughly in the middle of the cropped photo:
Double-click your image to commit the crop and you’re ready for the transformation! Just follow steps 1-3 as in the example above.
Here’s the final result:
