# test for ISOs which follow Annex G of EXIF 2.3 spec, i.e. ISOs,
# which cannot be represented by Exif.Photo.ISOSpeedRatings due to
# being larger than 65k

# All tests use the summary view as a result-check, because it uses
# the isoSpeed() "easyaccess" function, which handles the higher ISO
# readout.
