Some very basic questions about resolution

by jimbee » Wed Mar 29, 2017 10:10 pm

To this point for our 360 panoramas we've been using a 15mm lens on our Canon DSLR. With the FOV we've set the panos typically are consisting of 24 images to stitch in Giga. Works great.

What's not clear to me is what would be the advantages, or disadvantages of using, say a fisheye type lens? Less images of course but wouldn't the final output be lower resolution as well? By the same token using a 100mm to capture the same scene would require MANY more images to stitch in Giga, but how would Panotour handle that large a file?

Also, if we were to take, for example, three separate 360 panoramas-- one using a fisheye, another using a 15mm, and the third a 100mm, what happen if all three were a part of one single Panotour?

They would each have different resolutions, meaning different detail level and more or less zoomable (by default).

I unfortunately don't have any comparative tour for you for those cases, the most I have is the comparison between the 1rst gen ricoh theta (2 fisheyes) and a dlsr, but already from that you can see the resolution and detail difference , so you can extrapolate from that for other lenses. ;)

Those are great examples Annis and really clearly shows the difference between the two approaches. Thanks much! What lens were you using on the D800?

Also, I really like the drop-down menu for navigation. Could you briefly describe how you did that?

The menu at the top is a panorama menu, I don't know if there was any editing of the generated tour though.

I unfortunately don't have the exact setup used, all I'm given is that it was a Sigma Fisheye lens, on the R1 nodal ninja panoramic head.
