“Little planet” photography uses the Polar Coordinates filter in Photoshop. The idea is to take a horizontal panorama and transform it into a sphere.
It’s a cool effect that looks like it needs lots of Photoshop know-how. But it’s easy and takes only a few steps to create a small world.
In this article, I’ll take you through the steps to create your very own little planet photo. I’ll let you in on a few of my secrets in choosing images and making the process seamless.
How to Make a Small Planet in Photoshop
Choosing an Image
Little planet photos work well with panorama and 360-degree images. But photos of any image size will work.
I look for these characteristics in an image:
- Strong vertical elements like trees or buildings
- Matching left and right sides of the frame
- Simple sky and ground
The best images have strong vertical elements. The taller, the better. If everything is near the horizon, nothing will pop out of your small planet. The Taj Mahal worked great.
The effect is going to wrap the left edge of your frame onto the right. If these don’t match, you will see the join. This is one reason 360-panoramas are so good for this type of effect. But I’ve included a little trick in the steps below to help if your image edges don’t match.
Photos with a clear blue sky and simple ground texture are easier to transform into a small planet. The more details there are in the sky or ground, the more work you’ll need to do afterwards to make it look perfect.
The ground will become the globe. The sky will become the outside of the globe and the background. The amount of ground you have determines the size of your planet.
Step 1: Open Your Photo
I’m going to work with a cityscape of Chicago at night.
Open your image in Photoshop. Other programs like the free Gimp program can also create this effect.
Step 2: Straighten the Horizon Line
If your horizon line isn’t straight, open the Crop tool. Select the Straighten tool in the upper toolbar and drag it across the horizon. Photoshop will straighten your image.
Step 3: Prepare the Edges
Matching the left and right edges of your frame is an optional step, but it may save you a lot of clean-up work later. I’m going to match the horizon line by removing a couple of buildings (sorry, Chicago!) I’m also going to match the colour gradation in the sky.
- Select the left-hand section of your image. How much depends on your image, but I try for at least ¼.
- Copy onto a new layer (Ctrl or ⌘J)
- Flip the layer horizontally Edit >Transform>Flip Horizontal
- Move the layer to right edge of frame
- Add layer mask
- Select gradient tool set on basic black and white.
- Fade in effect from the centre to the right edge of the frame. The blend doesn’t have to be perfect.
- Merge layers Layers>Merge Layers (Ctrl or ⌘E)
Step 4: Create a Square Aspect Ratio
It might seem odd, but to create a globe, you must first compress the image into a square.
- Open Image>Image Size… (Ctrl or ⌘I)
- Click constrain proportions icon to unlink height and width image size dimensions
- Enter an equal number in height and width. I usually enter the smaller measurement into both boxes, but it doesn’t make much difference.
If you forget to make your image a square, you’ll get an oblong shape. This isn’t a globe. But you may like the shape.
Step 5: Flip the Image Vertically
Turn your image upside-down by going to Image>Image Rotation>Flip Canvas Vertical.
Image rotation will create a planet image. If you don’t do this step, you’ll create a hole. Your vertical elements will be inside. Try it! You might like it.
Step 6: Apply the Polar Coordinates Filter
The final step is to apply the Polar Coordinates filter. Go to Filter>Distort>Polar Coordinates…. This will open the Polar Coordinate dialogue box.
Select Rectangular to Polar.
That’s it! You’ve created a little planet image.
You may need to clean-up the seam where the edges meet. I use the healing brush, content-aware fill, and the blur tools to help blend the edges.
Many photographers like to do something with their backgrounds. I like to blur the tell-tale lines created in the corners. In this image, I added stars to the night sky.
Create Tiny Planets With Your Smartphone
You don’t need Photoshop to create a tiny planet. Many smartphone apps create small planet images in a snap.
It will even work on images in your camera roll.
Little planet photography looks out-of-this-world, but it’s easy.
Prepare your image in Photoshop by flipping it vertically and creating a square. Go to Filter>Distort>Polar Coordinates to apply the filter. There you have it!
You may create cool effects even in your mistakes, so you have nothing to lose!
