Panorama from the terrace of the "Kopitoto" TV Tower, which is not publicly accessible. Special thanks to the management and staff of the facility for access, patience and understanding!
The distance to the center of Sofia is 10 km (6 miles), so clear weather and low sun were key to making this quality gigapixel panorama. The photo was taken with the assistance of Canon Bulgaria, which provided the best possible equipment for the purpose: a mirrorless camera Canon EOS R5 and a lens Canon EF 600mm f / 4L IS III USM . The excellent stabilization gave us a chance to take sharp pictures even in outdoor conditions with a lot of wind!

 Technical and psychological challenges:

  • to stand on the edge of a facility almost motionless for almost 2 hours at 80 m above the ground;
  • to be super focused with hearing and vision to confirm each frame;
  • to choose the right focus point for each frame for all nearly 1200 photos;
  • to provide enough space on the cards for thousands of photos, each of which is 50+ megabytes;
  • to provide uninterrupted power supply for 2 phones, a panoramic robot and a camera;
  • to protect yourself and the equipment against wind gusts;
  • to finish the photos and to have a desire to repeat the exercise immediately in low light and strong wind! (The gigapixel taken with 1200mm from same spot)

Thanks to the heavy tripod, the stabilized lens and sensor of the camera, as well as the stable and precise panoramic robot Roundshot VR Drive, we were able to take this big picture. The camera was controlled by a phone - Live view for focusing and shooting, and for the robot we had two options - either wi-fi connection with the phone for programming and positioning or a radio remote for moving. Full synchronization between all components was a key moment in the project implementation. The panoramic VR Drive robot had no problem moving the large optics and the camera (its load capacity is as much as 20 kilograms!). The movement it provided for our project was between 1 and 3 degrees with accuracy 0.1 degrees. The results of this professional equipment are shown on this website!
We also used custom software to even out the exposure values and colormetric values of all photos in order to create a seamless panoramic photo.
