Two Questions

Hi Panoramers -- I have two questions:

1. I shot a series of photos for constructing a spherical panorama using a Canon 50D, and a Tokina 11-16 (set at 12mm). Using an online panorama calculator, I found that my hfov should be 63.67 degrees. However, when I run the stitching process using that figure, I don't get fantastic results (especially where the wall meets the ceiling). Any insights into a better way to calculate hfov?

Here is an example image set, in case anyone wants to see what I'm working with (not including floor/ceiling): http://dl.dropbox.com/u/9950969/Kitchen.zip

2. Since I plan to use Panoweaver and Tourweaver a good deal, and am new to the programs, I'm curious to know whether anyone has put together a workflow tutorial for the virtual tour process (in my case, spherical panoramas). If so, I'd be interested in purchasing it -- this post process isn't 100% intuitive, and it'd be really great to have some insight from some seasoned pros. Does such a tutorial exist?

Thanks!

G'day Ben,

Here is some answer for you.

1. Firstly the APS-C sensor Canon 50D with the Tokina at 12mm will give you approximately  63 degrees HFOV. So this requires 8 rotational images to complete the full 360 degrees with decent 20+ degrees of overlap. You will require 3 rows 0, -45 and +45 and a Zenith/Up, Nadir/Down shot if my rough calculations are right.

Your images show you have not "nailed" the NPP (no parallax position) and you need to take more care setting up your panohead. Here are two examples where parallax is evident in your panorama.

These areas should show no parallax between the same areas. This is sure indicator that your panohead/camera position needs attention and is the likely cause of stitching errors and misalignments. More help on this in this thread.

2. I teach all things panorama on a "One on One" basis. No set coarse, we work through things as necessary.

I will contact you privately.

Regards, Smooth

Thanks Smooth. Unfortunately, for those tests I used a panohead that I built myself. I've since purchased a Nodal Ninja, so expect better results next time.

I sent you an email yesterday -- did you receive it? Please contact me at benpopik(at)gmail.com regarding your instruction.

Thanks again.
