How To Build A Round Panoramic


This tutorial will show you how to build a round panoramic. I will use Autostitch and GIMP to show you the different steps, but you can probably transfer these steps to many other photo edit programs.


1. Start Autostitch and check settings

After you start Autostitch go to //Edit//Options//

 

The two parameters that I always change here are:

2. Have Autostitch do the work

All we need to do is now open the files and Autostitch wil do the work automatically. Go to //File//Open// select the photos You would like to stitch together and click ok.

You will see this status window. When Autostitch is done it will show you the stitched photo.

 

3. Start GIMP, load files, and touchup

After loading the file you have make sure that the horizon is absolutely leveled. Otherwise you are going to end up with a crack in the surface of panoramic planet. A little cropping and cloning, and you should end up with something like this

 

4. Make a square

To create a square we are stretching the photo in its highs. Go to //Image//Scale Image...//

First unlock the chain and overwrite the number in Height with the number you have in Width. You should end up with something like this

4. Transform it into a circle

To transform the photo into a circle shape go to //Filters//Distorts//Polar Coords...//

The value for "Circle depth in percent" has to be 100. The checkmark "To polar" has to be set. If the sky is not on the outside, uncheck "Map from top. If you do not have this option, you need to rotate the photo 180 degrees. With the offset angle you can rotate the circle. With this you have to play around a little to find what looks appealing to you.

5. Remove white background

Select the white background with your favorite selecting tool and remove it.

6. Touchup the seam

If you can see the seam too much, then use your favorite cloning or healing tool. At this point you can also rotate the layer as you like.

7. Enlarge the Canvas size

Go to //Image//Canvas Size...// and enlarge the width and height a little. Use the Offset to center the layer. I increased the width and height by 200 pixels each. So I can center the layer with the offset setting X=100 and Y=100 pixel.

 

8. Create two more layers

Create a new layer with a white background. Go to //Layer//New Layer...// and select Layer Fill Type White.

Create a new layer with the black foreground color. You should end up with the following layer stack. You may have to move some of the layers up or down. As the bottom layer you should have the black layer. The middle layer is the white layer, and the top layer is your globe.

9. Add a layer mask

Now let's create a layer mask on the white layer to create a glow around the globe, and to have the black background shine through the layer. First select the white layer, and then go to //Layer//Mask//Ad Layer Mask...//. Select Initialize Layer Mask to White.

Select on the white layer the layer mask.

Select the outer edges of the globe with your favored selecting tool. Go to //Select//Grow...// to increase the selection by a few pixel. I used 10 pixel for the value. Go to //Select//Feather...// to feather the selection. I used 50 pixel for the value. Now invert the selection by going to //Select//Invert//. You can use now the bucket tool to fill in the selection with black.

10. Create light effect

Create a light effect to give it more of a globe feeling. Go to //Filters//Map//Map Object...//

You have to play around with the settings to find the best for you.
