Image formats

The images in the image archive can be downloaded in seven different sizes and qualities:

  2. Large JPEG (original width x original height): Same size as the Fullsize Original, but in JPEG format (compression quality 80). Has low enough compression to be used for printed publications although the Publication JPEG may be better. No colour correction. Original colour profile embedded.
  3. Publication TIFF or JPEG: Publication-ready TIFF or JPEG files (compression quality 90), 4000 pixels large on the largest side . Has low enough compression to be used for printed publications. No colour correction. Original colour profile embedded.

If the colour profile of the Original image is either AdobeRGB or LStar-RGB, the image is colour corrected manually and no profile is embedded.
