[hugin-ptx] Creating a planet, how to best hide the camera?
Hi, in the gallery there are some amazing panorama photos created with hugin. I understand that i need the normal set of photos to create a normal panorama picture PLUS one or more photos of the ground. This is where the tripod stands and / or the sun casts a shadow of the camera and its operator. I wonder what is the best technique to get a photo of the ground, to hide the tripod and to not have a shadow of the camera and its operator? Thanks for any hints, Torsten. -- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

I thought of automating the process (in particular for Flightgear that is very customizable with xml) but I've almost zero knowledge on programming so they were taken by hand In FlightGear you can pause the simulation (use the p key) but you can still do things like pan or zoom your view or change the view position. So taking a set of screen shots for a panorama by hand is a fairly simple process. But automating it should be fairly simple as well at least for someone with some programming experience. But I think this would require using nasal rather than XML although you would use XML to map a key or button to the nasal script.

Re: [hugin-ptx] Creating a planet, how to best hide the camera?
Hi, For how to shoot the Nadir image, there are many ways. I use something similar to what is described here: http://www.rosaurophotography.com/html/technical6.html http://www.rosaurophotography.com/html/technical6.htmlThe most important thing is to test it and be sure you can place the camera the closest to it's npp. As for the shadows... position the nadir shot to avoid them, and gimp\photoshop them out :P Good shooting! nick On Thu, Jul 8, 2010 at 2:24 PM, Torsten Mohr tm...@s.netic.de wrote: Hi, in the gallery there are some amazing panorama photos created with hugin.

Re: [hugin-ptx] Creating a planet, how to best hide the camera?
You can take handheld shot with tripod removed. Hugin will automatically remove tripod from scene or you can use hugin mask feature. If you have ultrawide angle lens like 10mm than it will be very easy. But shoot at least 5 images. REMEMBER if your nadir is not alligned it will disturb whole panorama allignment. I only have 38mm lens and its really difficult to make nadir and zenith. But I have found a very nice way of doing it. 1. I manually stitch nadir and zenith in GIMP or Photoshop. 2. First stitch panorama with hugin in 360 x 180. 3. Now load it in GIMP. 4. Goto Filters distort polar coordinates 5. Now you will see your panorama in Planet view. (This method is basically used for making planets. But I have hacked it for nadir zenith stitch :) 6. Now you will see black hole in center of panorama. You can place zenith or nadir there. You have to use little post processing here. No pains no gains :)) 7. Now goto polar coordinates and convert it back to equirectangular projection. IT Can be lot easier if your dear developers add viewpoint correction feature like PTgui in Hugin. For Nadir you move back a little from tripod. Take a shot of nadir with camera tilted down and than in PTgui add view point correction for only that picture and if you have tripod option like Nicolas post than its simple way of do it. I hope it helps. If anybody has other tips please share. As I have to learn it hard way. Its good to share so that other people dont have to waste time.
