Stitching all blurry

Hi,

Does anyone know why I can't stitch these panorama?

https://www.dropbox.com/sh/9jtgs1bpo2xe ... lNyia?dl=0

https://www.dropbox.com/sh/mj1ufj2nj6da ... SQeza?dl=0

They just go all blurry. I've been back and reshoot everything a number of times and the panoramas never work.

Any help would be great.

Thanks

Hi..

Well, your NPP is way out.. There is no focal length data. You have not captured the zenith so its not possible to create a Full 2:1 Pano.. Your White Balance setting has serious issues.

All these issues will effect the final outcome.

The lens is manual and the camera settings are the same for all the other rooms (all of which turned out fine). Other photos had perfect white balance too and did not work

What is your focal length...

If you had success with other images, your tripod might have moved with these issue panos.. But for what I can see, the NPP is out heaps.. I will try again ..

BTW.. Always shoot RAW if you can and export as TIFs..

For indoors, set to 100 ISO and F8 is a good starting point. Since there are no people in the shot, if your camera can shoot bracketed shots, try at least 3 with +/- 1EV or better 5 shots with an EV of 2 +/- for indoors where window light is present. Use Photomatix to fuse your images then add to APG and stitch..

I tried your images again but without adding control points there will be issues..

Well, since you have had success with the same setting, either your tripod moved or the image features have issues..

With one of the panos you had success with, go to Edit in the right hand panel and export the Papywizard XML.. Then use that code to import your issues images.. If your tripod did not move, this might fix the issue..

I can send you the raw files.. Any idea where i can lear about control points?

No need to send me your RAW.. Just process the images, click on fixing WB, and other issues you might feel would help, then export as TIFs.. TIFs have more data so they often proved for a better result. Processing and Editing the RAW images has many benefits.. JPGs often cause issues..

Bracketed shots allow you to create Panos with beautiful depth of colour and eliminate blowouts of light emanating from windows and lights. This pano is made using 5 bracketed shots, with an EV of 2+/-. All TiFs... You can achieve high ranges of EVs using a Promote Controller.. This will eliminate any movements caused when pressing the shutter button by hand. If not a Promote, then a remote is essential.

1 It seems that the lens that you use have a focal distance around 8 mm in a 1.6x crop factor sensor (You must manually enter this values and adjust the type of lens to fisheye
2 Repetitive pattern in carpet cause erroneous control points detection.
3 Too much overlap. I only used images #1,3,5,7. Four images are sufficient. This helps too to limit erroneous control points.
4 As Destiny said, You must shoot zenith and nadir images for a equirectangular (2:1) image if you want create a virtual tour.
5 You can create a correct pano (we can help you here), save this as template and use it for future projects. With this, goodbye to the wrong control points. You must standardize a shooting pattern!
This last step is equivalent to using Papywizard

Hi Caleb

None of your images had and lens focal length data in the exif data so no surprise there were stitching and rendering issues

Your 8mm Fisheye should be set up as a lens to use if no exif data found as 13mm effective focal length (35mm)

In addition you had much too much overlap between the images (20% is recommended) and a lot of spurious control points

If you set the default focal length up, delete all the control points and reinput them so that each image only links to its 2 neighbours then the final image comes out OK (but should use +2 0 -2 EV bracketing to allow for the range of lighting conditions)

Im struggling to re-create what you guys have done...

This is how I did it
Open APG and using Settings | Images to set 13mm Fisheye as default lens type then save and close APG

img1.jpg


Shift click on the list of 7 images to select them all then with the CTRL PTS tab open shift click on the list of Control Points to select them all then right click on the list of selected control points and select Delete

img2.jpg


For exh pair of images 1-2 2-3 3-4 4-5 5-6 6-7 7-1 add in the new control points by selecting overlapping areas

img3.jpg


Optimise and render and then use the Horizon button to straighten it up

img4.jpg


That's all I had to do

Hi there..

Martin did really well with his results. I still have stitching issues, suggesting that your NPP is out.. But since it seems you have only done a single row, I am not sure...

Sometimes, with a plain coloured ceilings, you can get away with not shooting the zenith.. However, with your location with so many ceiling curtains, you need to shoot the zenith and nadir.

Your WB to me does not look right.. but you can fix that from RAW...
