# 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.
