Hi all,

I am new here and also just became a proud owner of a Gigapan Epic Pro, so please forgive me I if this question is already answered or of I am posting this is the wrong forum (this one looked the most active.. any way :) )

I need to shoot a complete 360×360˚ Spherical tour of a house (so indoors). I have a Canon 1Ds MkIII (full frame) a Canon 14mm lens and a canon 16-35mm lens. The rooms are big but not huge. I have been really worried about "getting the entire spherical image with the Gigapan.

And until now I still can seem to figure out how I have to do it. Can I somebody help me with it?

Regards,
Paul

Hi all,

As my Gigapan came with empty batteries I had to charge them. First thing I did in the morning was setting up the Gigapan.

I am very surprised by the way it is setup and how easy it is to operate. However if you look at the result from the first indoor panorama you can notice that there are a lot of stitch errors. Is there a reason for this?

Hi
I have done numerous indoor shots and have noticed a few stitching errrors, however never that many. The rooms I have shot are typically bathroom before and after shots for renovators.
I would suggest using a bigger lens, the smallest I use is a 80mm (Depth of field becomes a huge challenge).
Another thing to check is the alignment of your camera on the gigapan. There is an article on it some where but I am unable to find it right now.

Hope some of this helps

Hi Phil,

Thank you for this information. I guess the lower the focal distance the more parallax and other lens errors occur? Any way, I just did a 50mm version and it looks already much better indeed.

What do you mean with DOF becomes a huge challenge? High focal lengths means more difficult to get an overall sharp image?

Regarding Nodal point: I am not concerned about this at the moment. As long as the stitch errors are minimal I am happy.

Do you use Giga Stitch or PTGui?

Thanks again for helping out!

Regards,
Paul

Here is the 50mm version with adjusted nodal point.

Paul,
I have also found that if the gigapan is slightly off level the effect can be quite bad.

I use Giga Stitch, strangely enough I have found it to be the better of all the options.

“Regarding Nodal point: I am not concerned about this at the moment. As long as the stitch errors are minimal I am happy.”

You can ignore the nodal point as long as everything you shoot is far away from the camera.

When indoors you must get it right or you WILL get stitching errors.

Hi all,

Thanks for the information. I will re-level the Gigapan and try again.

In regards tot he Nodal Point. I have been reading about this. Can somebody give me idiot-prove (that would be for me) advise regarding how to setup it up properly? I can’t seem to find the proper information for a 5D MKII + 50mm amount of mm on the Gigapan Epic pro.

Thanks!

Paul you have some problems. The first, block the white balance.
Second the configuration of the FOV and the nodal point is for a Nikkor 17-55 2.8 f.
All the lenses are different. If you have the same lens this info will work, but if not, you need to find the nodal point.

Is not complicate. You need to see this video:
