Steve: not really the redundancy I'm looking for: you can't run Reed-Solomon on a print for a start.
Gavin: thanks, will have a look.

Ignoring the digitisation red herring for now (I'll solve it somehow, sometime), what do we reckon about the analogue parts? Is my projector plan reasonable or will it be dim or soft? Is changing to an all C-41 and RA-4 workflow going to make me happy or will I pine for Velvia?

Do people present projected exhibitions or are prints really the only viable medium? What about for your own enjoyment - I know that "come see my holiday slides" can be the canonical friendship-killer but what about "personal use only, officer"? Do people regularly shoot slides with the intention of projection rather than hybrid processing?
