About a year ago I mentioned that “Some fool has decided to stitch 196 separate images together to make a gigapixel image of Bryce Canyon in Utah.” Well some more fools have decided to up the ante with a 2.5 gigapixel image of Delft University in Holland…
Here are the mind boggling stats:
- Final image dimensions: 78,797 x 31,565 pixels
- Number of pixels in final image: 2,487,227,305 (2.5 gigapixel)
- Final image file format: 24-bit colour bitmap
- Final image file size: 7.5 GBytes
- Number of source images: 600
- Number of pixels in source images: 3,537,408,000 (600 images * 3008*1960)
- Lens focal length: 400 mm (equivalent to 600 mm on a 35 mm camera)
- Aperture: F22, Shutter speed: 1/100, ISO: 125
- Horizontal field of view of final image: 93 degrees
- Time required to capture component images: 1 hour and 12 minutes
- Time required to match overlapping images: 20 hours
- Time required to optimise project: 4 hours
- Time required to compose the image: 3 full days using 5 high-end pcs
- Time required to blend seams / correct misalignments / finalise image: 2 days
7 days work to put the whole thing together, and if it was printed out it would measure 6.67 m by 2.67 m at 300 dpi, and the level of detail in it is quite extraordinary, you can zoom in to read car licence plates… Madness.

Look! There’s a ghost at that street corner! Okay, now I have too much time on my hands…
yeah.. pretty good and useful website for me to do a brief research on gigapixel image.
