Ja sam sad (relativno uspešno) "napravio" jednu mikro Planetu po ovom uputstvu
... i to drugo Crop rešenje, jer je očigledno neophodno namenski
fotografisati (bez presecanja neba). :)
Step 1: Resize and Rotate
The first thing we need to do is prepare the image for the Polar filter. We do this by stretching the height of the image so that the image is a perfect square.
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)
Step 2: Apply the Polar Filter
Next, we’ll apply the Polar Filter to wrap our image into a sphere.
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.)
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.)

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:
1. 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.
2. 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.
3. 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:
4. 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:
5. 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.
