I'm going to Rome and Paris and everywhere inbetween this spring. I have a D80 with a couple of lenses. I'd really like to shoot in RAW but if I do, I estimate needing around 40GB of memory. I do NOT want to carry a laptop, and as this is a rather "budget" trip, I do not expect to be having access to a computer. Does anyone know of any devices similar to the Epson P-5000 but much less expensive. I've toyed with the idea of an iPod and photo connecter but I've read the batteries die quickly. I'm more or less going to be walking 8h/day and don't want to lose valuable picture taking time. Any ideas in the 100-300$ price range?
I think your primary concern should be reliability and not so much cost because you shouldn't be taking a chance on loosing any images. Even if you were to take a laptop, it would be at risk of getting stolen so you would also need a second method of backing up the images. That could be the Epson or even a 160 Gig Western Digital Passport. Not taking a laptop means that you should consider the Epson and maybe a stand alone DVD burner. If you're not a professional and don't sell your photos, you can do it by shooting JPEG and taking a bunch of 8 or 16 Gig cards.
One thing I recommend is whatever camera and storage you take with you, it never leaves your side, ever. And if you burn DVDs every day, mail them home daily so if your equipment does get stolen, you haven't lost your images.
As for estimating how much memory you'll need, always take at least 50% more than you anticipate using.
I'm not a professional. Unfortunately cost IS a concern. Does anyone have any opinions of the Digital Foci Photo Safe?
What I have found to be a relatively simple and cheap solution (i usually travel in less "civilised" places than Rome and Paris and I carry around a D200), is to drop into a photo lab whenever I am close to one, and have them burn my images unto DVDs (sometimes, netcafes will also do that for you). Cost is truly minimal (anything around 5 bucks per DVD or something) and then you can simply either carry the discs with you, mail them home.
