Actually I write it in "Notes" but researches can't be done in notes !
It's a bit more general, but I'd use the Credit field with the 'Artist' role
I'd agree. I've put those under artist as well and - if it's not obvious or requires a bit more explanation (as in the case of a photographer) then I include details in the Notes.
ok, thank you... but credit "Photographer/painter/designer" will be more accurate :-)
