For an Inkjet printer try Epson Semi Matte, much flatter than Luster,
work on your toning skills in Photoshop and you will have close to a G
surface.
For David, after years of not being able to use anything but a matte
paper with pigment inkjets there is a definite push against glossy
papers, the main argument being too much glare. After not being able
to put a darkroom in where I live now, I have been revitalized by the
current quality of upper end pigment inkjet printers and the new
baryta papers. Two especially are very close to air dried Ilford
Fiberbased gloss. Ilford Gold Fiber Silk, slightly warm and Hahnemuhle
Photo Rag Baryta which is neutral.

Yup, that was the surface I used, but made by Luminos...8^(
I also likely over washed those prints - so now metallic silver
has probably migrated to the paper surface, spoiling them
even further, sigh...! I liked the Luminos E surface at the time
for the deep blacks without the need for a high gloss to get
them. Much better papers arrived later, though...

Ritz camera carried them the last time I checked. I have them and they
are very good, but I'm having what seems to be equally long life storage
from Kodak pre-charged. Be careful, the package must say pre-charged,
they also have normal NiMH in a very similar package. Walmart should
carry these.

There are several different low-discharge NiMH batteries on the market
which seem to use the same technology -- Sanyo's Eneloop as mentioned,
Uniroos Hybrio and Panasonic Infinium. They all cost about the same and
do the same job, and come ready-charged out of the pack. I've got
Eneloop AAs, Hybrio AAs and also a set of Hybrio AAAs.

Anecdotally, I've had a pair of the Hybrio AAA cells in some
noise-cancelling headphones for several months, not actually using them
in noise-cancel mode much. They still have a good charge in them even
after that length of time. The other AAA rechargeables I have kicking
around tended to drain in storage after a few weeks to the point where
they required a recharge. I haven't used my camera (Canon A640) much
recently but it's been months since I recharged or swapped out the AA
Eneloops it's currently got fitted. I just checked it and it's ready to
shoot, no low-battery warning.

I suspect that the Kodak ones are simply rebranded ones from Panasonic,
or someone similar. Eneloop type batteries are ideal for the way I use
my digital camera.

I keep lithium batteries for backup. They last for about 300 shots, and
with 12 for $20, that works out to about three cents/shot. I can handle
that.

I understand (but am not totally convinced it is irreconcilable..) it is
simply because with contrast detection, the camera's af doesn't know
which way, or how much it has to re-focus, so it tries one way, dang,
then the other to look for improved contrast. Whereas phase detect
'knows' which way to go and also how far..

It seems to me a little intelligence could be applied to the problem,
and in fact the G1 already seems to get pretty kind comments about its
focus speed. I think this issue is gradually on its way out.

"A bit" would be like the difference between Canon's APS-C sensor and
Nikon's APS-C sensor. The Nikon is a "a bit" larger.

I think you misunderstand what I would want from a 48MP 24x35mm sensor and
expect I would get.

All I want is similar sharpness at the pixel level to what I've been
seeing up to now. And that means MTF50 at about 70% of Nyquist, which
produces very nice images on every dcam I've owned up to now.

I really don't expect the world to come to a complete end if the sensor
resolution increases by 1.5 times over what I have now. Again, with 21MP,
images are excellent at f/11, almost imperceptibly less so at f/16, and so
there's no reason not to expect f/8 to be similarly excellent at the pixel
level on a 48MP sensor.

So shoot at f/5.6. That may require that one use a better/more expensive
lens, though.

Huh? Look at the eyes of both girls. There is not much visible

the 1/3 (or 1/2) stop increment is only when using the control wheel.
in automatic mode, shutter speed and aperture (and iso with auto-iso)
are infinitely variable.

good luck trying to adjust the ring on the lens in between the click

Got an e-mail today from Kodak pointing me to the new Z980. Upon closer
investigation, I find it has a 24x (26-624 35mm equiv) zoom, has a second
shutter releas button for easier side hold photos, captures RAW as well
as jpeg. Captures video at 1280x720 at 30 fps. It's a 12mp camera. Would
be interesting to see one.

The specs and price on this camera are intriguing.
Unfortunately Kodak cameras have earned every bit of their reputations for

However at what will likely be a $300 street price what have you got to

I have a Samsung NV30 digital camera, but I guess all the NV series
have the video function out using the supplied AV cable.

I've selected the PAL rather than NTSC option since I'm in the UK. I
connect the camer's USB port to the TV digital inputs using the yellow
cable for the video and white for the audio. But I don't get anything
on the screen of the TV and the LCD of the camera just goes blank,
with the power still on.

Has anyone used the AV cable supplied with an NV model successfully?

Thanks.

We seem to be talking past each other. Sure, those that are
*really* interested in photography are likely to be able to find
sensor dimensions with little effort. Your last sentence above
seems little more than a non sequitur truism. If what you see in
the viewfinder is less than what you get (for most DSLRs), and isn't
a concern, then why be concerned about the inaccuracy of using 1.5
as the crop factor for Nikon's DSLRs? It also promises a little
less than you actually get, and the difference is trivially small.
The advantage of using crop factors is that they only require simple
math. Telling photographers that they should use arctangents
instead violates the KISS principle but might be useful in that it's
likely to convince many to avoid asking you for further help. :)

Never mind. Today a colleague "corrected" one of my slides in a ppt
