My Autopano Pro forum

Au fait Alex, j'ai un doute, j'ai cru comprendre que les 'erreurs' de blending venait du fait qu'un blender de type multiband avait été utilisé, à cause du temps de calcul qu'aurait pris smartblend, ce qui explique, entre-autre, pourquoi le ciel est peu harmonisé…
C'est ça, ou c'est du à autre chose ?
Je me doute aussi que le placement d'image, à la main, n'a pas arrangé les chose.
C'est dommage, car c'est le ciel qui saute le plus aux yeux.
Enfin, ça reste une prouesse…

Hey… Steve, be fair please, this was only a small question to Alex.
English is not my first language, and after making some efforts in talking english, i felt i could ask that in French…

BTW: there is no French section in 'Announcements'

Here is a better online translator, that still makes funny grammar - As I do -

Question about the (fuzzy) foreground: I believe that including the building roof, the water tank, etc, is intentional (the result is the view don't looks like an aerial view) but wonder whether the author would be more happy if this foreground was crisp or just don't care...

Note: that an artist is experimenting with high-resolution mosaics is the main point for me, not the gigapixels contest!

Hi Gurl,

If you look at the picture of the camera, there is a 30lb counter weight to compensate for
the lens position.  The small movement between shot creates ALOT of vibration.  The
pixorb's stepping motors had to be adjusted to accelerate and decelerate so the vibration
was minimized.

Diffraction is a big issue when shooting with a telephoto lens.  Although the D2x is 12mp, it has a very small and sensitive sensor.  Diffraction is an issue above f11.  A choice was made to prefer the long reach of the lens, hence the softness of the foreground.  A telephoto lens also collapses space.  If you look under the water tower to the building behind it there is alot of space in the scene due to the softness and the crispness dispayed against each other.

Of cource a constant Af system to focus on everything all the time is a logical next step with some help from APP..(if photorealism is the goal)

What things look like (good or bad) are expectations derived from taste and experience.  Something like hypervision is a new experience. That's why I'm doing this.  I think the blurring may be more understood, when the printed image arrives.  It may optically act as a foil with one's peripheral vision.  Much like the composition in Flemish landscape painting, though they also used shadow to force the eye to light.  When posting a 77' x 13' image on the web, one must understand the method of delivery is a personal one and is experienced on a screen.  I tend to think of zoomify as a Chinese scroll painting.  One was never supposed to unroll the whole thing to examine, only roll and unroll moments forward or backward in time like film- David Hockney

I appreciate the thoughts and suggestions.  There will be more to come, with more experiments!  When 1.4 arrives, the whole process will not take 8 months, but one week.  The Harlem website was a special event.

A quick search on google: 13 gigapixel

I have taken the most interesting ones…

Yes, there were of course an influence on APP website stats. For the first day, 3x, second day 2x. Now, it's quite over.

by the way, you can save to psb, open it in photoshop cs3 and export to zoomify (new is cs3)

We tried that, but didn't work, the exported part was corrupted.

Is it ( theoretically ) possible stitch a 1000 image pano, by first stitching 4 parts of 250 ( + overlap ) and the the 4 parts ?

Something possible is to optimize the whole pano (using all source images), then to make some adjustments in the panorama editor if needed but to make several partial stitchs (several Render actions). The Layers Editor could be used for that.

It's certainly possible to optimize and render subsets of source images but this is much more difficult. For rectilinear panos each part must be stitched using exactly the same location for Center Point and this would be very difficult. For cylindrical or equirectangular panos the horizon (the horizontal gray line shown in the panorama editor) being at the same height would be enough: not easy but certainly easier...

Using PS to assemble the parts into the final pano should work ...but would be very slow when dealing with those very large files.

When using PanoTools to stitch no more than 200 shots (some year ago!) I had to use partial stitchs for cylindrical panos. PanoTools can stitch cylindrical source images but I probably used PS for the final step.

Using the Layers Editor could be the easiest way to use Smartblend to blend the sky of Harlem.
