I carry a minimum of at least ten 4Gb Sandisk Extreme III (SDHC) cards all the time and their weight is next to nothing and they take little or no space in the pockets or bag. If your images are important to you like mine are, treat yourself to more cards, you won't regret it, rather than trying to use a compressed shooting medium. This is how film was in the old days, memory cards are the same and should be treated as almost a cheap consumable item and it is false economy to skimp on this. Especially when you consider how much we all spend on our camera bodies and even more on good fast glass. You owe to yourself to obtain the very best possible image from all shooting situations. It’s not about making mistakes or using a more forgiving medium, as you are already aware, the histogram that appears on a compact camera or digital SLR screen is unreliable for anything other than jpeg capture. This is because the histogram you see there is actually based on the camera processed jpeg and is not representative of the true raw capture. Hence the only way to check the histogram for raw capture is to open the image via a raw processing program such as adobe camera raw or something similar. In raw you do still need to get the best exposure setting you can at the image capture stage, even bracket exposures as necessary in order to obtain to the ideal correct one. As for white balance, raw captures the light and light quality as it was at the actual exposure time, not a perceived or enhanced version. Sharpness is down to the lens quality, focus and camera operators’ ability to take the shot. When shooting jpeg this all these are set in camera, with the values you preset or the camera default setting, applied and then compressed with loss, before you even get to see the result on the lcd. At least with some post process software, CS3 for one you can apply some of Adobe Camera Raw settings and tweaks to jpeg and tiff as well as raw. what I meant for forgiving medium is that you can still fix a lot of mistakes using RAW, and preserve top-level image quality, where you'll lose a lot if doing same with jpg, so in case you forget to return EV to 0 - RAW won't mind
sure, right exposure is right exposure, no matter if it's raw or jpg, agreed, but there's still way more room to tweak and squeeze with RAW...
I'm sure that anyone who has ever experienced a 500+ shots to post-process is well into batch-processing, so time is of little importance if you know what to do, make adjustments to one shot, synch all others, check every now and then, and that's the beauty of RAW, but jpg still needs a lot more work for each photo since it's more specific...
as far as space comparison issue goes, once I simply forgot all my mem.cards in my other bag, so the only thing I had with me was my 1gb sd card, which was kept in my battery-grip, so I switched to jpg and got through the assignement...
histograms make no sense if you're shooting raw, but you can't really go without them in jpgs, especially with tricky lighting, at least I can't with my k10d... again, I'm still for RAW, but - if you're in some kind of trouble or really need to go with jpg for any reason - it's not such a bad thing, just need a bit more attention
