Hi Michael, I think you are moving in the right direction. First use what you already have and invest in new equipment once you have a better feeling for what you need or want. It depends on your specific situation and requirements or wishes. I mentioned that I use fisheye lens and the reason is to keep the number of shots low (I need 6 to cover full circle plus one straight up and one down - that last one I take after removing the tripod hand-held). I shoot with Nikon so I bought their 10.5 mm full frame lens for cropped sensor cameras. But any wide angle lens would do. Or even not a wide angle if you want to do gigapixel panoramas. In that case you will probably shoot large number of photos - the opposite of what I am doing. The principles of stitching will be the same.
In order to have least amount of paralax errors, using a panoramic bracket is advisable but not strictly necessary for outdoor. Yes, Nodal Ninja is one popular option. I had my bracket custom made by a friend. It's not perfect but does the job for what I need. Another option could be one of these - http://www.360precision.com - Or you could try some cheap product from China as sold on ebay, but I haven't seen or used them so cannot comment if they are worth the money. Regarding the pupil location, look how to identify "nodal point". It's fairly straightforward. You want to make sure that an object close to you is in the same relative position against background on both overlapping shots you are stitching. See for example this answer - https://photo. stackexchange.com/questions/47220/how-do-you-find-the-nodal-point-of-a-lens Cheers, Tomas ---------- Původní zpráva ---------- Od: Michael <[email protected]> Komu: [email protected] Datum: 14. 9. 2016 23:08:58 Předmět: Re: [darktable-user] 360 degree panoramas " Sorry about having a broad question but I am just starting out with this so I must start broad. And my broad question led to (what I suppose) are broad answers which is just what I need as a starting point. So, I suppose I will start with some specific questions: What equipment should I get? You say a fish eye lens. Other sites I've looked at in my research recommend an 8mm. Is that good? It has also been recommended I get a nodal ninja. Would you suggest that as well? I there any other equipment you would recommend? You mentioned a "panoramic bracket".... What is a "panoramic bracket"?... my investigation into it shows that this is what a nodal ninja is but I need to be sure that they are the same thing. One thing further when asking around about how to identify the location of my lens "pupil" I was told that it was more or less in the middle of the lens... even with a zoom lens. HOw would I find the pupil with the 8mm (which I will get later) and with a zoom lens (which I have now).

Personally I use Darktable to process my panorama images before a stitch and then stitch them using Hugin. More elaborate processes might have their advantages but I like to keep it simple. I shoot with DSLR + fisheye lens, tripod and panoramic bracket to keep the number of images low and stitching relatively easy. There are also specialised 360 degrees lenses available on the market, but I haven't experimented with any of them. As a general intro, read for example at http://www.digitaltrends.com/ photography/photography-101- how-to-shoot-360-degree- panoramas/ (http://www.digitaltrends.com/photography/photography-101-how-to-shoot-360-degree-panoramas/) If you chose to use Hugin for stitching (it would be a natural choice on Linux), there are useful tutorials available - http://hugin.sourceforge.net/ tutorials/index.shtml(http://hugin.sourceforge.net/tutorials/index.shtml) I noticed that the panorama you referred to is using Flash for presentation. I would suggest using a JavaScript based panorama player these days. Flash usage is generally deprecated. Check out for example free software https:// pannellum.org/(https://pannellum.org/) - You can see more examples of its use on my site - https://tomassobekphotography. co.nz/panoramas.php (https://tomassobekphotography.co.nz/panoramas.php) As you can see, your question is a rather broad one. Panorama photography might have a steep learning curve. However it is rewarding and worth the effort.
