This is a great full-spherical pano! The quality is amazing, and the subject very nice. Very good job!

stunning !

Hi,

my first spherical panorama with my Merlin:

65000*32500px, 2.1 gigapixel, 233 images:

Hi Tobias!

Great!!

best, Klaus

Very impressive, thanks for sharing

Henrik

Very impressive. Now I really want to get myself a Merlin/Papywizard setup!

F11, but it needed for 81 images to use focus stacking:

I understand focus stacking but what do you mean here about needing 81 images?

Thanks

Brian

81 of the 233 images required focus stacking, I hope you understand now?

Did you shoot focus stacked images for the entire pano and then later select those shots that required focus stacking? I mean did you repeat the pano shoots wiith automatic shooting several times with a different focus setting or did you shoot step-by-step and addjust the focus for the stacks as you shot the pano? O5r did you use some sort of tehered shooting focus bracketing script?

How many different focus settings did you have in the stack?

What software did you use for focus stacking of those 81 shooting positions before you stitched the pano?

I shoot with the template and when I come to a position where are required a different focus I paused the shooting. Then I shoot the different focus points and after this i started the automatik again ( step-by-step ).

2 or 3

Tobias,

Thanks - now I understand - that's very clever. Because doing it that way the XML file still works with the stacked focus shooting positions.

I am in awe of your imagination, dedication and ability.

Absolutely incredible! Details, details, details!!!

Did you use a custom preset for shooting?

Yes, Zenit and 8*29:

As having 29 images per row results in the proper overlap at the horizon level (aka along the the equator of the sphere) the other rows are including too many shoots.

This is not obvious on the above preset image because it uses the equirectangular format. This would be obvious if using Autopano tool to display overlap of top row images (in the preview the topmost images have a larger extent than the pitch=0 images.)

I will skip the (sinus (pitch)) maths and only say that a more refined preset would includes about 150 images rather than about 230.  Probable benefits:
- shorter shooting session
- less lighting differences when outdoor
- smaller memory card, less battery usage, faster and more secure Smartblend rendering
- much faster optimization and better RMS.

Improvements in optimization and RMS are impossible to predict but "too much overlap" results in an excessive number of links and in a very  inadequate global repartition of the links (in your case a huge number of useless links at the top of the sphere for example.)

To verify the above is easy: delete source images in the top most rows (leaving for example 4 images only in the row next to the zenith image) until overlap is too narrow...
