Correct off set of image in panorama

[David W Cox]

I have been shooting with D750 and Tamron 15-30 lens resulting in 99 to 115 images so it is hard to manually edit and move the specific part to re-align plus I am new to the finer points of the software. I would like to correct this image. Was shot between two doors and look to me like two images need to be pulled into place. I am having a hard time figuring out what one to move and how to correct.  Is it best to do in ptgui or photoshop?

I have all control points set at 5 plus optimized multiple times, and it does not move this section in the door jambs. Any suggestions. Attached is the project file and sample pano. Thanks in advance.

Hi David,

The problem is parallax. You need to calibrate your panoramic tripod
head. See 5.4:
https://www.ptgui.com/support.html#5_4

Also, a 15mm rectilinear lens isn't the most easiest choice for taking
indoor panoramas. It gets much easier if you use a 10 - 12mm fisheye
lens, you'll need to stitch far fewer images.

Kind regards,

At first, I was going to say no way since others and the exact next one came out great. I thought about it and my process is the following. Thanks for straightening me out.  I use a nodal ninja and for the last shot I take and move the tripod 6-12" and move the upright to the end and turn it out for the last shot. I must not be bringing it back to tight up against the stop for the right set distance. In my work process, I must be getting sloppy with that. Thank you. Any good way to fix this shot that you would recommend?

HI Joost,

I believe this reply was meant for another David (W.Cox). Mi issue was banding in the sky.

Dave

Hello

I have started doing pano photography again and wondered

what is the best full frame body/lens combo for doing pano photography in 2019?

Also recs for pano heads…

Thanks

..its all about details and sharpness. Im using Canon aps-c with variations between lenses 50mm flat and 16 mm Wide Angle with pretty good result. Im waiting for a 35mm to be used too.

Adjust all pictures in LightRoom make it better.
See my example 16mm WA (90 pieces) at:

Hi Peter

I would always recommend FFS over APS-C or cropped frame sensors. It simply gives you more pixels and more resolution. In terms of lenses this depends on vertical field of view required. With a 50mm lens in portrait you get approx 40 degrees, but with a 24mm lens you get up to 80 degrees. But you then get a  loss in resolution.

I like the Manfrotto 303 SPH because it is built like a tank and will outlive you.

Have a look at a few of my attempts here:

Good luck!

Mike, This query has nothing whatever to do with the topic you have hijacked, which is "Correct off set of image in panorama" .

I should also have mentioned that I also use fish eye lens on occasions. I have the canon 15mm prime lens. Whilst I get reasonable results this isn’t an area I have great confidence in because of the difficulty in removing parallax. 

Another advantage with FFS is that the sensor avoids the crop factor. So you don’t have to go ‘ultra wide’ angle with your lens.

But I really think half the fun is in discovering all this for yourself. There is an excellent book on HDRI panoramas which was recommended in a PtGUI discussion group which I would highly recommend by Christian Bloch.

Sorry, this is not completely true. Most APS-C sensors have a much
higher pixel density than FF sensors, hence you get a higher resolution
with APS-C, at least if you use the same focal length. See
https://wiki.panotools.org/DSLR_spherical_resolution for details.

The benefit of FF cameras is the larger pixel size, which gives you less
shadow noise and more dynamic range.

Dare I suggest you are partly right. You will find the Canon 5D mark IV and 5DS/R have many more pixels than you will get with a cropped frame sensor.

But I accept that some older FFS cameras can have less resolution than newer cropped sensors.

You can’t simply compare lens results because cropped sensors change the effective focal length.

While they certainly have more pixels this is of less relevance for
stitched panoramas, where only the pixel density counts. A 20MP APS-C
camera has the same pixel density as a 42MP full frame camera. So using
the same focal length on both will give you a panorama with the same
resolution.

[Mike Spence]

That's very interesting Eric

I must admit that I was under the impression that I am ending with more detail from my 50mm on my Canon 5D Mark IV at max resolution than an APS-C at max resolution when saving as a TIF. The APS-C will crop top and bottom of the panorama because of the cropping factor.

So what you are saying is that because of the cropping you are getting as much detail in the image than the FFS?

I suppose if verticality is important then you would use a 35mm or a 24mm with an APS-C to give more verticality at the expense of pixel resolution?

The final resolution of a panorama is determined by focal length and
pixel density (pixel / mm), nothing else. Read
https://wiki.panotools.org/DSLR_spherical_resolution

Detail is a different thing. It also depends on the lens sharpness (lens
resolution). Of course a higher pixel density needs a higher lens
resolution as well.

You are always free to shoot more rows if you want more vertical coverage.
