The only software that can reliably work with .afphoto files is Affinity Photo, so if you are looking for way to export AFPHOTO format to PostScript format (.eps) via afphoto to eps conversion, then you have to use this software. If you have not tried it before, there is a trial version available that might be enough for the export, otherwise you have to either purchase license or find someone who can do this export for you.
