How to: Copy all control points from one project to another
vonRasmussen
I’ve prepared a HDR panorama - well I’ve made 3 exposures at each
camera position (adding up to a total of 228 images), and now I’m
working on building the spherical panorama.
To make it less heavy on my PC, I’ve first made a panorama with one
set of images (the “normal” exposure images) thus reducing the number
of images to 1/3.
It took quite a bit of work to insert control points on the ground
images, as the light was very low.
Now I want to build the HDR panorama. Is there a way to copy all
control points from the “light” version of the panorama into the
panorama holding all 228 images?
Kind regards

project of the first pano as a Template; don't optimize, go straight
to the Output and export the pano with a new, descriptive name i.e.
pano-dark for instance. Repeat the steps for the third pano and you're
done. You can also, before export the pano, save the project with a
new name and batch-stitch them all at once.

Thanks for your reply.
My plan was actually to create a new project with all 228 images,
enable true HDR. But I would like to "import" the controlpoints" from
the "light version".
When I read about template in Help, it's my understanding that control
points are not included. I might be wrong here? You suggest I make a
template from the "light version" and import that template into the
true HDR version, right?
Kind regards

The control points are not needed for stitching as long as you don't
optimize. The template contains the exact positions and other parameters
of all images which are needed for stitching, so you only need exactly
to follow Rodolpho's advice: "don't optimize, go straight
to the Output and export the pano with a new, descriptive name"

If the Panorama is made on a tripod with exact positions of each image set
then do the following steps:
One exposure of your HDR-set is aligned and optimized
1. Load the two other sets with "add images" on "source images" tab
2. Sort the images with a click on the "a-z" button (needs proper naming
of images)
3. In the menu "Images" click on "link hdr bracketed exposures"
4. On the tab "exposure / hdr" check "enable hdr stitching"
5. Make your hdr setting
6. Output your Panorama and ignore the warning changed control points

The only experience I have with HDR pano is assembling 3 versions of
it - one well-exposed, one sub-exposed and the third over-exposed -
and combining them. That's how you should follow my instructions; it's
not necessarily correct in any other environment. After the 3 panos
are stitched you HDR them in the software of your choice.

angles are linked to the list positions of the input files. By adding
the other images you change the list order e.g. if you're using your
middle exposure, images 1 and 2 from your first project become images
2 and 5 in your second. Peter's answer is how it should be done (and
it's simpler)

This is wrong. We where under the impression that you wanted to astitch
each exposure step separately. Of course it can't work if you apply a
template for 77 images to 231 images.
If you want to stitch all 231 images in PTGui pro you don't need to use
templates at all. Simply load all images into PTGui, make sure bracketed
sets are linked and proceed. Linked images are positioned the same,
hence this will work only if you shot from a tripod.
To first align 77 images from one step and then use the positions for
all 231 images is possible under some circumstances: If you add the
missing 154 images to the already aligned panorama with 77 images and
then sort the images on Source Images tab your previously aligned images
must start with the first image (then will follow two unaligned images
and then the second align one and so on).
If this is true on Image Parameters tab choose Link HDR. This will
assign the positions of the first image of each set to all other images.
If you shot -2EV, 0EV, +2EV f.e. and you stitched the 0EV step first,
save the OEV step as template, then load the -2EV step and apply the 0EV
template. Then proceed as described above.
This technique fails if for some reason the images can't be ordered in
the described regular pattern.
However, I don't think the whole procedure will save you any time or
computing power from loading all images at once.

Thank you all fro your helpfullnes. I've used your input, got all
images aligned and it looks much better now!
Only I didn't use the auto-sort function, as I understood that the
images I manually positioned had to be the first in a set of three. It
took some clicks with the mouse to move up the 154 images, but it's
done now - and *a lot* faster that starting all over manually
positioning the images PTGui couldn't position.
Thanks a lot, guys!
