I have a problem with a Pano.

These two photos go in:

This comes out:

I've tried High detection quality, Low detection quality, more control points, less control points, etc but nothing seems to fix it.


Thanks!

Lol. It's a simple question. What other information do you need?

EDIT: I've highlighted the problem in the picture below.

I guess these were shot handheld?

What camera and lens did you use?

Were they shot from the same location of did you move betwen shots?

Did you use the same settings for both shots? For example, same focal length?

I uploaded the originals. They're in the first post.

No, on a tripod.

Canon T2i + Sigma 20mm f/1.8 Prime Lens.

Same location, of course.

mediavets wrote:Did you use the same settings for both shots? For example, same focal length?

Yes, everything is identical. The only problem is the tear between the stitching.

Lol = :D

*scratches head*

Well, I've seen it asked several times.. I just don't know what it's called so I can't search the forums.

You know what I'm referring to.. the portion that isn't lined up properly - where one side is higher than the other, like the end of a texture on a series of polygons.. kind of looks like the aftershot of an earthquake..

Come on, you know what I'm talking about :P

I think you just proved that it's possible to get rid of the stitching errors in a pano by just taking out the two overlapping shots and stitching them on their own :)

Next question then : how do you put this back into the whole pano ?

Does his pano comprise more than these two images?

LOL I hope so unless he's going for the worst panorama ever produced

(in post 1 Track says these two shots "go in" so I assume it's just a small part)

And the best thing is : I just loaded the two pictures, did detection and rendered it. No extra work whatsoever, everything on default.

He can dropbox me the other pictures to do the whole panorama, it's routine for me ;-)

Hans: he wanted to know what he was doing wrong and wanted to know how to correct it himself.

Afaik he wasn´t looking for someone who does solve the issue it for him.

The problem is, I had no issue at all, unable to reproduce the problem ;-)

It brings attention to a more general problem, not every photographer is a stitcher.

I think that is why we would hope you explain how you improve the stitching procedure so that we can benefit from that knowledge

I hope the OP puts up the whole set of images not just these two so we can get a better idea what the problems are

I suspect the perspective difference between the two images in this part of the pano may be causing problems. On the right hand side of both images, the angle between the buildings and the road is very different on each image

I had just done a clean install of the latest version of Autopan Pro and it stitched the pano with only some minor errorrs in some of the lighting columns.

There you have it. There is no problem with the pictures!

You name it! And of course that´s fully ok!

The problem is: as a photographer doing panoramas you need to know at least the basics of both - photography and stitching.
When somebody tells me he doesn´t want to learn it it´s not on me to convince him to do learn it nevertheless - but then he/she´d better give his
work away to get it done and pay for the service.

I have good experience with real photographers that I teach panorama-photography. They bring so much knowlegde to the equation that once they've learned how to make a panorama they combine that knowledge with what they already know about light, composition etc.

Your last sentence is what I see more and more and am building my business on. Photographers realise that they can't do everything themselves if they don't want to spend a lot of time learning the stitching technique. As long as I return them a good quality panorama and sometimes layers, they can see the win-win situation. Together with some hosting and ICT and integration support this works fine for both parties

I'm sure that's very true but the point I was making is that people who go to the trouble of posting ON HERE with their APG stitching problems are very likely to want to know how they could improve their technique not just hand it all over for someone else to solve with no feedback

As an outsourcing arrangement for busy professional photographers, that is a different situation and I'm sure you provide a valuable service

Right - but when you buy a car you need to learn how to drive. When you start to shoot panoramas it´s the same. Doing panoramas means to know or to learn at least two things:

1) how to shoot.
2) how to stitch.

Expecting everything to go automated is a bit blue-eyed. In the end it´s photography, as said. If the way of shooting isn´t appropriate - it´s either impossible to achieve a good stitch or
it needs WAYS of work to compensate faults which would have been avoidable with more basical understanding the shooting-process.

When issues rise one needs to know where they come from to compensate them. Here we again have TWO things which need to be understood:

1) photography
2) stitching.

Some people say they don´t want to learn the basics. Ok - their decision. But it means to need asking for help each time an issue rises - without learning that most of the issues are connected
to each other that means permanently asking for help.
So when a photographer doesn´t know about perspective, distortions, the way different focal-legths act in terms of stitching, shooting distances related to focal-lengths and so on he/she inavaoidably will run into issues.

Even the best post-pro guy or gal not always will be able to make a faulty shoot a perfect stitch.

Amen. ;):cool:
