It's often said that using Pyro developers (and no doubt others) a negative can be produced that will print well in both Platinum and Silver.

How practical is this, and what film/developer combinations work best?

I'm interested in producing negatives that will (contact) print well in Silver now, that I could print in Platinum down the track. Any advise on how I should set myself up?

I'd be very interested to see some side-by-sides of Silver and Platinum prints made from the same negative and would be grateful for commentary about the film and developer used or difficulties in printing (beyond those inherent to Platinum).

Thanks
