About This Category
This section contains calibration items, primarily to set up and test the equipment and software we use, and to see what sort of settings to use. If you really want to use exhibits from this section, you may, but remember that these are not meant to be works of beauty!Adam portrait1 bg AJHD.jpg ... Adam portrait1 normal AJHD.jpg
