But if you are working on a gigapixel panorama with bracketings with 5 up to 9 steps, I guess that there is no
HDR-software that can handle this big amount of data.
Here my hope is still at APG.

Hi Klaus
How do you mean that exactly?
I guess the problem with the methode in the tutorial is that there is no HDR-software that can handle gigapixel input files to do the tone mapping.
As the editor says: "None is truly working" of these workflows. And below: "Create a panorama for each bracketed exposure".
But what if the panorama is several Gigapixel big and the bracketing has 9 steps, eg. from -4 to +4 EV to cover the extreme dynamic of the scene?
I try out such a case but first do the HDR for every single image. Then stitch them together and try to blend them properly in APG.
But the color correction in APG clearly wasn't able to blend this mosaic usefull together. It wasn't a surprise, because the individual HDR-images were really different.
So the first rule "Rule 1: stitch first, build HDR later " is correct in this context.
The second rule "Rule 2: never use a panorama tool to create and edit an HDR image" is also correct at the moment, because APG isn't able to do the tone mapping. It only support fusion and the results aren't comparable to those e.g. from Photomatix.
But which other software can handle really big input files to do that.
And the main question is still: What should we think about this publication in the Kolor forum?

That is correct.

Is this 10 gigabyte or 10 gigapixel ? Good to know anyway.
My experience with panos created and stitched together from HDR-images those were preprocessed in Photomatix is not very pleasing.
Even when using "templates" that means everytime the same settings for every batch processed image.
The differences between this preprocessed images are to strong (eg. when there are also sky and clouds in the image) so APG isn't able
to blend them properly and usefull.

But there is: you can do it in parts - using the same preset there´s no problem running several batches of x images each.
Limiting depend on your machine´s RAM i guess.

What makes you think so?
best, Klaus

I have tested a lot of hdr softwares on windows, osx & linux, only 2 has pano tweak: easyhdr & sns-hdr. The first is great but sns is very powerful for big amount of pictures.
ps: i attach an exemple
