So I've finally accomplished my largest panorama. The process was lengthy (~20hours of work), which is why it took me so long to stitch. The exposure date was July 12th 2005.

The complete picture is 78 megapixels, which I downsized to 10.6 Megapixel for viewing.

This panorama represents my summer quite well, which I spent working in Krakow, Poland... I found the place on the Main Square which offers the nicest and most complete view of Krakow at Night for a 360 panorama.

Krakow at Night (1.6Mb)

For those who care:

It consists of 17 vertical pictures taken at 29mm on my D70. However, each picture consists of 3 exposures, which I superimposed and edited to extract the large dynamic range of the nighttime scene. The main exposure was:

- ISO 200 - f/8.0 - 15 seconds

Followed by two exposures used to get detail in all the much brighter areas of the scene.

- ISO 200 - f/8.0 - 6 seconds
- ISO 200 - f/8.0 - 2.5 seconds

With a solid tripod the superposition of the 3 exposures was impecable.

Here's a sample of the 78 MP version to appreciate the amount of detail it holds.

PS: Thanks to Adam and Jean-Remy for bearing with my lenghty photoshoot in the middle of the night in Krakow. (We're all standing on the bottom left corner during one of the exposures)

While I'm at it... Here's a picture of San Sebastian, Spain, which I visited in August.

It's a 4 picture stitch.

Here are two more 4 photo stitched panos, but lower quality...

1) JonnyB and I chilling on Wawel in color.
2) Same scene, but in infrared.

You might be interested in the latest version of PTGui which supports the photoshop big document format.

That Krakow at night is a really cool pano - nice job!
12/30/2005 02:08:25 AM · #5
I really like the Krakow pan. Very nice!
12/30/2005 02:09:17 AM · #6
how did you blend the exposures?

Holy Moses, that Krakow pano is impressive. So nice to see one from "inside" instead of an "overview, the much more common approach to pano...

I manually blended the exposures. Going around details and following building lines and such. Another big part of manual blending is that you can remove all the lens flares given that your pictures overlap enough.

so basically layer masks, and soft edges?

Both of those shots are very impressive. Truly amazing work. Well done!

That's right. I export it to a photoshop file with layers without blending(which I actually open in Corel PhotoPaint - same difference) and erase the indesired overlapping elements.

The edges of the pictures become noticibly less sharp than the original because of the warping done by PTGui, so the overlap is usually right in between two pictures. Except for when lens flares are present... then I prefer having less sharp sections for the final pano.

now that is well worth the effort it took. Really good job!

Beautiful pano, Aleks! I really like how you worked with the exposures to gain dynamic range, the result is impressive!
12/30/2005 09:14:20 AM · #19
seamless and beautiful
12/30/2005 09:22:42 AM · #20
very nice...
12/30/2005 09:46:43 AM · #21
That is absolutely gorgeous. Just awesome.
12/30/2005 10:06:43 AM · #22
It really is beautiful and expertly seamless... but I have one question. Are the folks and the building in the first frame the same, but flipped, for the last frame? Or is it just looking past them again, like past 360 degrees? I just got confused. It's gorgeous though. :)

edit... the harbor picture is absolutely amazing...it should be in some travel magazine somewhere. Wow!

Ok I've got questions.

first of all, very,very good pano's. Very excellent job.

1) Did you use a rig at all for the shots? (Bogun, Kragen) If so which one, and do you like it? Or did you quess.

2) What stitching program did you use?

Again, well done.
12/30/2005 10:13:19 AM · #24
Wow amazing both of them well done. I am amazed, wish I had the patience or scenery to even attempt something like this. Wow again.

I love the pano that guy with the camera with the flash going off is a great touch
