I am using a D70 with 6megapixels.  For what I do,  I would like to be
able to print without pixelation at as large format as possible.  I
bought mine when 6mp was the most i could get.  But now I know there
are cameras with more.  My question is, is changing cameras the only
way to get more pixels?  It sounds awfully wasteful to me (I'm totally
fine with the rest of D70.)  Do they have a way of upgrading just the
buffer capacity?  Or other ways of upgrading from D70 without getting a
new camera? Any info will be appreciated.  Thanks.

You are talking about UPSAMPLING.

If you are working from a raw file, you can get slightly better results by
making this adjustment.
The resultant file will be larger. Convert to 16 bit. Save to PSD or TIFF
format, not JPEG.

You would do well to get in the habit of using a tripod if you intend to
enlarge your images.
The tripod will help you get very sharp images. Get the IR remote.

Auto focus is nice, but sometimes manual focus will work better.

Good lenses help a lot.

One option is to stitch a number of photos together, there are programs
that make this pretty easy and once you are stitching you can go to
very high numbers of pixels.
Here is a sample that I did
http://www.pbase.com/konascott/image/72258285/large
you can hit original at the bottom of the photo to see the full 39MP
image.

The program I use to do stitch is PTGui, but there are others out there
as well.

As far as upgrading you camera to more pixels, sorry that is just not
in the cards.

PTGui is excellent. It looks like the new CS3 will be very good as well.
Also look for Autopano.

Impressive picture Scott.

The number of MP is dependent upon the chip, not a buffer.  Either the chip
has the pixels physically embodied or it doesn't.

It is one of digital's little nuisances--you have to continually upgrade if
you want to remain near the top of the technology curve--and the price your
current camera will fetch will be only a fraction of what you paid for it.

The alternative it film...where it just stays limited to roughly the same
capability.

chalk, since pencils give an unfair advantage, due to finer and finer
tip-point technology."

How large is "large format" printing for you?

Thanks to all for your help.  This is really helpful.

I am an artist making instllations/performances mostly.  So I have
wanted to document my work and since they become the only things that I
can show after the actual work is down, I have tried to make the
photographs as large as the content demands.  That of course depends on
the piece.  But in general, I find that I constantly need to get close
to 20"x30" size, which I believe needs about 15~20MP to hold without
too much pixelation.  Sounds like none of the currently available
cameras have that high a resolution.  But if the CCD is the part that
determines the pixels, then it seems to make sense to me for the
manufacturers to make that part interchangable?  No?

But back to the point, given that we can just swap the chips, I do find
Scott's suggestion very intriguing and perhaps the closest to a
professional solution to a large and detailed photograph.  It also
sounds quite natural after he pointed it out.  Dah!    To try things
out first, could anybody suggest a good quality public domain photo
stitch program to start with?

Thanks so much.

michael

p.s.,

I just stumbled into making conceptual work with photographs lately and
started to take lots of random shots.  It warrents a really small
pocket camera.  And I was thinking in the same terms in that I was
looking for super high resolution point-n-shoot, which invariably turn
out to be with big cameras.  But with this stitching alternative, I can
really shop for small camera size now.  Thanks indeed.

Great.  I also checked out the other ones.  Also, the new point-n-shoot
canon I just got today came with its own photostitch program (it even
has a 'stitch assist' mode!)  Sounds like
I'll be busy for a few days.  Thanks for all the help.

What you really need is a medium format digital camera/back not a '35mm'
DSLR.

Check the Mamiya (22Mp) and Hasselblad (22 or 39Mp) systems... there are
others too.
These do have removable backs/CCD blocks with the ability to upgrade to a
higher resolution when they become available...

You will require fairly deep pockets for these systems, BUT they do have an
upgrade path, offer superb image quality and will use a variety of excellent
lenses.

Not an option, digital cameras are built around a chip, the only
cameras to have removeable chips are the high end  medium cameras and
the Leica R8&R9. Look at $20,000-30,000 for a medium format camera,
$10K for a leica setup with one lens. Too much is linked to the sensor,
the image processor, software and basic design. Would cost more to
switch out a processor than a new camera costs.
If you are interested in the best photos you can get, get a good lens
for your D70, a 17-55 f 2.8 Nikon or an 17-50 f2.8 Tamron (much less
quality). If you dont mind single focal length lenses a 60mm f2.8
micro, 35mm f2, or 50mm f1.4 Nikkors all would serve you well,
especially if you are stitching (less distortion).
Getting more pixels in your camera would also work, a D200 would give
you 10mp, in large prints that makes a difference. Wouldn't be that
difficult to get a 20x30 from a D200 file. Again good lenses make a big
difference.

If you are going to try stitching there is a free demo version of PTGui
you can try.
Also when shooting the photos it will work better if you get a fair bit
back from the artwork and use a longer lens, a tripod would also help.
You will also want to shoot in full manual mode to keep the exposures
all the same.  Make sure you give a fair bit of overlap between the
images as this makes them easier to stitch.

No way to get more pixels from your present camera. You can consider
photoshop plugins like Genuine Fractals Print Pro or some that use s-spline
technology, which will allow much larger prints without blocky pixelization.
It will smooth the edges but will *not* give you better resolution.

It's worth considering that pixel size in a print is a function of the
square of the total number of pixels--so a 12 Mpix camera like the D2x only
gives you a print about 1.4x the size of your 6 Mpix camera before you get
the same amount of pixelization.

No.  For example, if you have many (say 16+) shots of the
same scene from the same point of view, you could try
   http://en.wikipedia.org/wiki/Anti-Lamenessing_Engine
Be aware that this needs a _lot_ of computer time for larger
images, and there is no nice "I don't have to think"-GUI.
