Thanks for the suggestions (and thanks too to the other listers who responded).
'Pleasure <g>...
Try some shots & look @ the results. You may well be pleased with what you see.
I think that's what I'll be up to tomorrow eve.
Rob, I do hope you'd post the results. Then film photogs <g> would be able to cut a little the number of the experiments to be made <g>...
Thanks!
Boris
