I think at this point I'll just keep the leica originals (if I can). Can't say that I can see any difference in the converted versions from the Leica or Olympus to adobe's DNG.

For example my M8 DNGs are often 5 or 6MB. This is different to what the M8 does, it is a part of the DNG spec not used by Leica. The trick is to 'convert to DNG' in the import even when they are already DNG. But you need to change another setting or so. I have recently upgraded to CS4 with ACR5.1 and I don't have it working with that yet to tell you where it is. Just get a portable HDD or two and duplicate everything on to (at least one) separate drive when you import it into your laptop. Then you have two copies letting you re-use the cards. You can use ACR and LR to automatically make a backup copy when you import. That's a lot cheaper than a stack of extra cards. The 2.5 inch notebook HDDs are cheap enough in portables. Maybe 100 to $150 for 250 to 320GB at Officeworks or the like.

They are dng, but do not use the M8's "compression". I keep them as Leica DMR RAW: I think my external disc and back up will be big enough, and I'll take some DVD'S. I have used LR (which is camera Raw 4.6 I think, but every now and then someone including Leica talk about Capture one as being "superior" in some way. Don't be jealous, get on board ;-) Actually, I suspect if the Aussie Dollar languishes in its current hole this might spell the end of expensive trips for me for a little while. I'm not sure my soul could not cope with a trip to the US at 50c again!!!

If you convert to DNG you will not lose any information anyway. For the M8 of course that is what you will have anyway. The only disadvantage for a non-Leica camera would be that the camera maker's proprietary software would not read them. Although you can embed the Raw file in the DNG as well that will make it larger and gain you nothing for during the trip. We can talk more about Raw converters when you return. Absolutely nothing lost in the meantime. Oh and I'm insanely jealous once again about this new trip. Watch out for amorous leopard seals. Don't wear your seal coloured fur coat either.

In the arctic with the 180mm and 2x converter, I tried to use 1/3000 when I could, but it seems I might have been a bit paranoid. I'm testing a bit before I go. Things tend to not move fast in the antarctic, but from the zodiacs, you do get the same roll. I still don't quite understand the differences that a RAW converter can make over another. Perhaps I should look at Flexcolour.

Typically I use ISO 400 with -1 exposure compensation, but that's really just a starting point or for when chimping is impractical. More often I'll review the histograms of the first few exposures to be sure I'm not clipping any highlights, and to set the exposure so the histogram is as far to the right as possible w/o clipping. I have the display set up to highlight clipped pixels. > Also, any comments about what to do with the files: > should I keep them as the big 20meg files Yes. I use Imacon Flexcolor so I can't comment on C1 or LR. > Any hints on handling? Boy just typing this is making me keen to "get > out there". Minimum acceptable shutter speeds will vary from one person to the next, from one day to the next, and from one situation to the next. On dry land with the 560, shoulder stock & monopod, I try to stick with 1/125 sec or faster but this isn't a strict rule. I've gone slower to 1/60 sec, and if I'm in a hurry or the critter is moving 1/125 sec will be too slow. In the kayak I often use 1/3000 sec because EVERYTHING is moving: the bird is swimming on ripples that are making it bob up & down, the kayak is being pushed laterally and turning from the slightest breeze, plus the kayak is rolling slightly, bobbing out of sync with the bird, and its roll angle changes as I turn to follow the bird. With the 280mm lens on dry land with shoulder stock & monopod 1/60 sec is often fine (subject motion permitting) and when I have something solid to lean against 1/15 sec sometimes works too.
