The ALPA 12 PANO offers new dimensions for "flat stitching" with very large formats, in which the image circles of the lenses are used to their limits. The following photo (1) is a result image, which is stitched to a format of 108 x 54 mm or 2:1. It corresponds to the view of a 33 mm lens and produces - after minor cropping - an impressive image that measures 23,500 x 11,500 pixels. The same is true for shooting on an IQ3 100 or Hasselblad H6D-100c. In comparison, a 270 MP digital back would be required. The second image was taken in the same aspect ratio but with an IQ4 150. In this way, you get an image with huge 25,400 x 14,100 pixels or 404 MP sensor equivalent.

SAMPLE IMAGE 1‍

• ALPA 12 PANO
• IQ3 100 (no trichromatic)
• ALPA / Rodenstock HR ALPAGON 90mm
• Stitch 34 mm left / right = format 108 x 54 mm
• 10 mm Shift (up)
• Approx. 0.5° tilt
• Aperture f8
• Size 23,500 x 11,500 pixels
• Equivalent 270 MP
• The 90 mm lens corresponds approximately to a 33 mm lens.

PANO/ROTATION STITCH WITCH CROP‍

In order to achieve the comparable framing, the image from a rotation pano needs cropping.
