Largest compound digital image

The largest compound digital image – that is, an image made by combining lots of smaller digital images – is an image of a sagittal section of a 1.5-mm-long (0.06-in) zebrafish embryo that measures 921,600 × 380,928 pixels (a total of 351,063,244,800 pixels, for a net data content of 281 gigapixels). The image was composited from 26,434 individual electron microscopy images taken by Frank G. A. Faas and his colleagues at the department of Molecular Cell Biology of the Leiden University Medical Center, Netherlands, using an FEI Eagle CCD camera. The acquisition process took more than four days and was completed on 8 December 2010. The team responsible for the image comprises Frank G.A. Faas, M. Cristina Avramut, Bernard M. van den Berg, A. Mieke Mommaas, Abraham J. Koster and Raimond B.G. Ravelli.
