Thanks for the response, Kilgore. What software do
you use to tone-map such large images?

LOL! Now *there's* an idea! One could use the
glasses to watch movies filmed like this. Only one
question - what should we call it? Ghastlivision?

When I return to Bath, you need to have for me a
pair of glasses that I can wear and see vistas
like this in real time.

Um, I am not up on the proper terminology for
tone-mapping so let me explain exactly what I did.
First I took each image at three exposures: plus
2, 0 and minus 2EV. Then I stitched all the images
together using Autopano. Then (in Autopano) I
created three layers, one for each of the
exposures. This gave me all the plus 2EV images
stitched as one pano, all the 0EV as another pano
and all the minus 2EV as a third pano, and all the
panos line up with each other. Then I rendered
each layer to give me three gigapans that line up
with each other when superimposed. Then I
tone-mapped the three gigapans to get what you see
here. Does that answer your question?

So each tile is a single-exposure HDR?
The Gigapanographer Currently Known as "Kilgore661" (March 03, 2010, 08:53PM
Thanks Tom. I generally shoot at plus and minus
2EV i.e. 3 exposures, but it is the gigapans that
are combined, not the individual images.

You really seem to have nailed the HDR thing,
Kilgore! How many exposures are combined for each
