Yes in this case the use of the word “stitch” is very correct. This refers to a photo stitch process that was used for this truly amazing photographic work by Julian Kalmar. This shows the glory of the fully restored Piaristen Church in Vienna built circa 1715-22
My story here is about an innovative business photographer. He is not only a good at his craft, but he has also perfected a unique process to make this world first photo.
Aside from the process being used like this for valuable historical documentation, it seems has great potential many other areas such as selling. Learning, Industrial and Business processes.
To see for yourself click in the picture to take you to Julian Kalmar’s web site. When, I contacted him, Mr. Kalmar told me he is presently using a shared hosted service which is sometimes closed when there is heavy traffic. If so he asks you to please just try again later. And believe me it is worth it.
And when you do, be sure you pan around his 360 degree views too look around and up & down and zooming in and so one, you get a sense of actually being there looking at all the beautiful detail.
For the technically minded, the photo size is 51644 x 25822 pixels to make it a huge 1.3 gigapixel. Most cameras amaze us with photos using around 10 megapixels. Put in proportion Gigapixel is 1000 times the size of one megapixel, so the technology to get to and exceed the gigapixel barrier is actually quite incredible.
You may have seen Google Maps with their street maps where they join house photos to make a seemingly continuous imagine of a street with rotational views. When you zoom, in on the close ups you can sometimes see where they are joined. Stich technology does a pretty good job lining up photos, but the job of blending the seams is not so easy, especially for very fine work.
The Kulmar photo stiches over 250 photos to make just one picture. His clever technique not only has them all joined up seamlessly but he has also achieved an amazing overall consistency of focus. What is also so very useful is you can zoom right up close anywhere and still see very fine detail with great clarity without blemish.
Mr.. Kalmar very generously told me how he was able to achieve this. I will attempt to summarize this here:
“What makes this photo so unique is not the stitching of the several hundred of images, but the focus blending technique used in the single images. Focus blending is used very often in macro photography to increase the depth of field.
With 70mm, the depth of field is not enough to get near and far objects sharp in single images, no matter what aperture you are using. Stitch results will then have un-sharp areas. To avoid this, on any likely problem images, Mr. Kalmar took several shots with different focusing points and then combined these into one image, so he had only had sharp images for his stich process.
He noted that when the focus of a lens is changed, so is the focal length, This results in stitching errors. It is possible to eliminate errors manually but the edit process on the entire stitched panorama like this one would take many months. To resolve this Mr. Kalmar said he had worked for nearly a year to perfect a process to handle this problem.
Julian Kalmar right now, is the only photographer in the world able to make spherical indoor panoramas in Gigapixel resolution. That is also the reason, why he now has the largest spherical indoor panorama in the world.
His business is making beautiful pictures His general site is http://photoartkalmar.com/
I would be sure there will be many industrial and commercial uses for this type of photographic application. I am also sure Julian Kulmar would be more than willing to discuss with them with anyone interested. He can be contacted directly on email@example.com In my contacts already with him I have found him very approachable .
We also plan to follow his progress and we wish him every success with his innovative stitch in time approach.
