These are two examples of my Polar Panoramas. To make your own planet, you start with a 360 degree panorama, with a clear horizon line. you make these by taking 10-15 vertical pictures with 50% sky and 50% ground while turning in a circle. The pictures MUST have a 10-15% overlap, or the project will not come out right. Once you have your pics on your computer you open them in adobe photoshop, and photo merge them, and if you took your pictures correctly, it should work perfectly. Crop it so it is a rectangle. Once you have the pano exactly how you want it, change the size of the image to 5000 x 5000, than rotate it 180 degrees. If you do not rotate it, it will turn into a spherical panorama. Once you are ready to make a polar panorama, click filter > distort > polar coordinates.
If you want to add a person to your polar pano, have someone take a picture of you while standing on a stool or chair, (Be Careful!) and perspective is EVERYTHING!!! If you don't get the shot from above, it won't look real. Open the photo you want in photoshop and use the Quick Selection Tool to select the background, then right click, and inverse the selection. Feather it, and add it to your polar pano. Command C and Command V (copy and paste) your person layer and Turn the exposure down and opacity to about 40% for a shadow. Place it where a shadow would be and there you have you standing on your very own planet!!!
