I have been working with consumer digitals as my car club's sole editor for a while now, and am planning to purchase a D70 soon. For those of you who shoot weddings all-digital; I can visualize accidentally fat-fingering or mistakingly NOT dumping a card to temp storage, and later finding an empty folder - which would be fatal to a job, and horrible... Do you use multiple cards, and NO-offloading/reuse? Offload to a CD or disc, or laptop? It seems like the only sure way (or safest)would be to have all- single use memory cards, clearly labeled, and bagged, then download them all afterwards safely at the PC. So what? enough for 300+ shots at RAW size plus cards for backup? What is your workflow?
