Who shot what with which camera body?

[StanJirman]

Only the suggestion of taking a picture of self and swapping memory cards is actually workable, even if awkward, when SWAPPING cameras.

You could switch some custom function (use the three different CFn setting pre-sets) to later distinguish based on that. There should be an "innocent" CFn that you can change, and as part of a whole CFn bank switch through PFn it should be pretty quick - even if not super smooth.

Use the voice annotation to label the first and last shot you take. Remember to use continuos file numbering.

... and one that I've used when passing the camera about. "Ken start" "Ken Last", etc.
