The first step is to shoot all the photos you need for your panorama. If you have a tripod the results will be much better especially as this is a HDR PanoPlanet and you want each bracketed shot to align as much as possible.
To shoot a good panorama, you should set the camera in portrait orientation on a tripod, with the widest lens you have. Take meter readings at 90 degrees apart to get the average light reading in all directions. Then set the camera to manual and use the average settings you just read. Now set the camera to bracket exposures either 3 or 5 (if your camera can do them) I usually select 0 +2 and -2 stops to give the widest range.
Repeat each bracketed shot rotating throughout your 360 degree panorama. For example with a 16mm lens on a full frame camera I need to take eight shots to make up a full 360° view, add bracketing means I need to take twenty four photos to make the panorama.
I use Corel products for the photo editing side of things (as well as the other HDR packages) but am unsure how to create the earth distorted image. Could this possibly be done in Corel Photopaint?
I attempted to search for world images but you can imagine the results...
The whole process is too complicated for me as I don't have photomatix and only an old version of photoshop (and am not that well acquainted with it) - but it's a great 'ible and if i had the time I'm sure i could do something from your instructions. Thanks!
