OK, I know of the Snelling Eye Chart used for checking our own eye performance, but what other reference charts are availble for use in the field to assist with comparing video camera performance in the field? I cant seem to remember the name of the one used in the UK that starts with and "R" (I think).
What other devices / charts can be used and what are their dimensions so I can reproduce them on an enlarged CAD plotter?
Thanks all.
