I just tested my CF cards for RAW write performance using the criterion set at the Rob 
Galbraith page (http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-6432) and 
found that my new Ridata 2GB 52x Pro cards deliver 1758kB/s which puts them just 
slightly behind the Sandisk Ultra II and 
Extreme in his table. My old 512MB CF cards were spec'd at 20x and came in at 
1566kB/s. I'd be interested to see what difference if any the new Write Acceleration 
technology might make.

What it boils down to is that if you need to engage in continuous shooting in RAW past 
the 5 image buffer you'll be looking at about 7seconds at the very least between 
subsequent images even using the fastest CF cards. If you need to keep the buffer 
empty you need to shoot JPEG.

The Pentax photo lab (PPL) white balance is very nice, but I only need
it so often.  I haven't had quite as much luck as Bill with the manual
white balance.  That indoor swimming pool (where I have done most of my
manual balancing) has the most troublesome lights.  I also wonder if the
lighting changes from one end to the other.  Anyway, the PPL with raw
fixed that well, so if I suspect a difficult white balance I switch to
raw.  Most times, however, ***L works fine.
 As for exposure, I admit I'm not quite good enough with that
Curves-style tool to make those fine adjustments worth while.  I
practice when I can, however, and hope springs eternal . . .

There is a big point to RAW besides extra resolution that you might
get from avoiding compression artificacts.  RAW saves 12 bits of data
per pixel (instead of 8) and the data hasn't been run through the
white balance or exposure code yet.  As a result you can make sweeping
white balance changes and better exposure changes than you can make to
a JPEG file.

You're probably right, but I've had no problems with either pre-set white

I've found RAW to be an advantage WRT brightness range and shadow detail in 
some specific instances (ie hand held low light shooting) however I can 
generally get away with saving JPEG in camera. I really can't see any clear 
advantage in saving TIFF in camera.

I'm not complaining about the absolute cost of digital storage (it has saved me 
cash and will continue to do so) but more so about the relative cost of the 
highest capacity cards. I'd always prefer a few larger cards than a pocket full 
of little ones. 4GB cards are disproportionately expensive, next year they will 
be affordable.

Shel, I have never hidden the fact that I shoot large/fine jpeg. My
criteria for selecting a suitable resolution for the vast majority of
my
shooting were these:

What level of quality would be required to produce good inkjet prints
at
a maximum of 16"X11"?

What was the trade-off between RAW and large/fine jpeg WRT how many
pics
would fit in a reasonable space of memory (CF cards).

Two test prints, side by side, illustrated to me that there was no
visible difference between RAW and large/fine jpeg, so the answer was
clear cut for me.

BTW, I have never said that shooting digital is a good deal. I have
always said that I have enjoyed it - it is a hobby, and as such I
don't
have to be able to justify the cost, like anyone doing it for money
would
have to. I've got half-gig cards and that's all I want to pay.

For me it's all about having fun and not justifying anything! LOL.

  Cotty

Personally I wouldn't touch a microdrive. CF all the way for me. They say
that dropping one shouldn't damage it inside, but I'm not going to test
that theory out with my storage. Stands to reason that something with
moving parts inside might be more susceptible to damage..

They are quite delicate, you have to handle them with care. Also they are
slower than fast CFs, and startup time of *istD will be 3-4 s. instead of 1

The fastest cards on *istD are undeniably Sandisk Ultra II and Extreme. So I
bought Sandisk Ultra II 512 as the one having good price/performance ratio.
Lexars despite having utilised by *istD Write Acceleration feature, are much
slower and more expensive than those which were faster... See results of

the specs on the MicroDrive and CompactFlash show that the Microdrive draws
about 7 times as much power when writing and about the same when reading. at
idle, the MicroDrive draws slightly less, but then has about a half second
delay from the time the camera signals it wants to write until it is ready
to write during which time it draws the write current.

The Microdrive draws about twice the current of a CF card.  That said;
I've put over 300 images onto microdrives (some RAW, some JPEGs) using
one set of 2100mAh NiMH rechargeable batteries.

As for damage: as long as you don't drop the camera while the drive is

Tanya & Frank should probably stick with CF cards, though :-)
