Andrew Varlamov: Great Catherinians Behind the scene : how this panorama was made Let me begin from EXIF citations : White Balance = Cloudy, Quality Level = RAW, Sensitivity = ISO 200, Aperture = F/8.0, Manual Focus Pentax Fish-Eye 10-17mm: Focal length = 13 mm, Shutter speed = 1/20-1/45 sec for overexposured shots (-1EV), 1/90-1/125 sec for underexposured shots (+1EV) Tokina AT X-Pro 28-70mm: Focal length = 65 mm, Shutter speed = 1/8-1/15 sec I had got only 3 days to shot panorama for this event (because my weekend was devoted to my family affairs). September 19 was rainy day. September 20 was opened by sunny morning, but after noon sun begun to cover by more and more dense clouds. At 17:00 light became soft and uniform, but rain was ready to start. As You see monument to Catherine II is circled by low stones connected by chains. There are 25 stones, and shooting points were chosen in front every second stone. When I finisned 1st circle around monument I thought that 13 is not suitable shots number and performed additional rear shot. Then Pentax Fish-Eye lense was replaced by Tokina Zoom Lens and I went 2nd circle. 42 shots were made during 25 minutes. Shots processing was divided into: merging of dark sky with overexposed shots (for general view) shot rotation (maximum angle deviations were -1.9 and 1.1 degrees) shot scaling (maximum scale was 116.8 %) shot centering shot cutting brightness/contrast adjusting As result shots of size 3008x2000 pixels were transformed into shots of size 2960x1800 (loss of width = 1,5 %, loss of height = 10 %). To satisfy WWP requirements for files sizes the next parameters were chosen for QTVR object consisted of 2 rows by 14 frames: standard version: frame size = 526x320 pixels, quality = 55% full-screen version: frame size = 1110x675 pixels, quality =55% Return
