10MP raw vs 16MP jpeg

Sometimes space is an issue, and I have used 16 MP JPEG 4*.
Does anyone know how 10MP RAW would do in comparison to top notch JPEG?

You'd have to do that comparison between something like a K10D and a K-5, since RAW assumes the highest resolution capability of the camera. If space is an issue, you may as well shoot 10Mp JPEGs - as long as you're happy with your exposures and don't need latitude at each end of the dynamic range in PP.

There were some discussions a couple of years ago about JPEG 14 Mp, 10 Mp, 5 Mp, with 1, 2, 3, or 4 stars. A general consensus, I believe, was that it was best to shoot JPEG at 14 Mp (ie maximum resolution) and lower "quality" (less stars) than the opposite.

Hope that the comment makes sense...

Thanks, both of you. I'm quite comfortable with 16M 4 star jpeg, in these situations (document tours with my band). It is the full raw files that becomes a tad too large for comfort. Then it just struck me, 10M raw, could that be something? I'm a novice in raw processing, so I'm happy for all useful information.

With to-days memory prices space shouldn't be an issue = buy more cards

Or, transfer shots to a laptop or similar after each session? I use multiple small cards + laptop + portable data storage device. I only clear and reformat the cards after the shots are safely on my main computer/storage.

And safely on backup disk/dvd as well?
The only time I didn't do that, was with pics of my wife's birthday!

I used to think space was important. I was wrong. Memory and storage are incredibly cheap now (as I look back on decades of buying RAM and disks). A 16GB card in my K20D holds something like 650-700 RAW shots, which is a busy day's work, I tell ya! On the road, I carry a small external 500GB drive and my laptop, and migrate files as needed. I haven't clogged-up yet.

are you only considering space or image quality?

also note that I don't think you can scale down the resolution of the RAW image.

RAW means RAW, data direct from the sensor.

PG 200-202 of the K5D manual is pretty clear on this

You are absolutely right about the raw - i found out myself when I got home to my camera
I'm thinking convenience - this is pictures of the band which are to be spread quickly via mail/electronically, I'm afraid I will not have the time to work with the raw files. Not yet anyway - you probably noted I'm not yet very experienced.
Also an issue I want to contain as many pictures as possible on my Mac (320GB harddisk). I'm currently using Aperture3 for adjustments/managing.
