Storage, Blur and other issues

Hi,

Haven't yet got a digital camera but I'm pretty close to making the big leap
from film. But before I do I'd like to get a few questions answered.

I downloaded a few 5MP images taken on a Nikon Coolpix 5400 (thats where my
research is pointing right now) and each image is just over 2Mb in jpg
format. Converted to TIFF's they weigh in at 14Mb plus. Now the card
included with the Nikon is 16Mb which is not a lot, allowing for 6 or 7 jpgs
or 1 TIFF image. Now last year on a 3 week holiday I shot 8 rolls of 36
which is 288 images plus. It's fair to assume that I would have deleted some
of these along the way if I could have.

Is it possible to increase the storage to 1Gb? Since this would give
sufficient for a similar trip.

Many of my landscape pics have a degree of "movement" in them. I like to use
long shutter speeds (1 second+) to blur movement such as waterfalls,
breaking waves and the like. Does the same principle apply with digital
cameras? Is there a physical shutter in the same way as a film camera.

Finally.....

Using Photoshop I can see that images I downloaded are 2592x1944. At 72dpi
this gives an image of 36x27 inches.

Whats the deal with printing this image at A3 size? Increasing the dpi will
reduce the image size but how do I take advantage of the 2880dpi claimed by
printer makers ?? Changing the image size in Photoshop to something like A3
results in a dpi of about 166 dpi.

I'm foncused as you can tell.

Any direct answers, or pointers to web resources much appreciated.

TIA
Andrew.

According to Nikon:

Storage System: EXIF 2.2 file (uncompressed TIFF-RGB or compressed JPEG)
Design rule for camera file system (DCF); Digital Print Order Format (DPOF);
QuickTime Motion JPEG (Movie, Audio) Media: CompactFlash™ Card Type I/II,
512MB/1GB Microdrive™Card

Question 2 yes.

From my experience with a 990 and now a 5700, you'll find very few
situations where tiff gives you anything extra over the highest quality
jpeg. You might consider the availability of raw NEF storage if/when Nikon
issues the firmware upgrade that is supposed to provide this functionality.
Yes. you can use larger storage media. One additional thing to consider is
a smaller card and a portable hard disk based storage device instead of
just a large card.

Forget about thinking this way. The dpi of the printer and the ppi of the
image are totally different concepts. Take a look at
http://www.scantips.com for instance. The original image is just X by Y
pixels. For best results you'll need around 300 ppi in the final printed
image. The actual best value is highly debatable, but I'll use this as a
guide. You can resample the image in PS to the desired size and ppi if you
want. Another choice is using a program such as Qimage (PC only) to do this
for you.

Yes, you can put a 1 gig CF (Compact Flash) card in the 5400 or any
other digital that takes CF for that matter. But you don't need a gig of
storage. JPG is 99.9% as good as TIFF and MUCH smaller. TIFF is all but
useless.

Go to http://www.scantips.com/no72dpi.html and read. It will answer your
question.

You can use different sized Compact Flash Cards in your camera. My
_suggestion_ is to consider four 256MB cards instead of one 1GB. Most
people who have been using CF cards for awhile will have a story about a
corrupted file or card that trashed all the photos until they could get to
a computer and remove the files with a program written for that (or the
photos were unrecoverable). My conservative view is to spread the photos
over several cards so that if any one of them becomes unuseable for some
reason, you still have others to use. It's like not putting all your eggs
in one basket.

I'm not familiar with your camera model; many point and shoots do not allow
the user to set shutter speeds. Check your manual.

Good point. Question: are CF cards susceptable to magnetic fields or X-
Rays? Do I have to worry about carrying them through security at airports,
and/or packing them in bags that are nowadays subjected to even higher
levels of X-Rays?

What program do you use to recover the photos in a corrupted card?

I have only anecdotal information -- Louise and I have carried both CF
cards and floppy disks through airports with whatever X-rays and magnets
they use (along with unexposed and exposed film) with nary a problem.
Whether this is a reliable datapoint is for each person to decide.

I'm on a Mac, and I use PhotoRescuse for Mac OS. See
http://www.datarescue.be/
for more information -- the program is written for Windows and Mac OSes.

Yes, 1GB compact flash cards are fairly affordable these days. Or get
two or three 512MB cards.

Yes, it does. However, noise increases with longer exposures in
digital (it's what we were cursed with in compensation for not having
film grain any more).

The 2880dpi isn't relevant to pixel density; that's *dots* per inch.
Each dot isn't a pixel -- it can't be any arbitrary one of the 16
million colors (from the 24-bit space).

In general, thinking about dpi will confuse things. In photoshop, go
to the Image resize dialog, make sure "resize" is UN-checked, and
simply set the print dimensions you want.

*Then* look at the resulting dpi value. If it's not horribly low,
you're fine. If it *is* horribly low (100dpi is horribly low; 300 dpi
is just fine), you still might want to try the print, and see how it
actually looks on paper. At low resolutions, you fairly often get
results that the rules of thumb don't promise you from inkjet
printing. I've got several framed 8x10 prints on the wall printed at
around 105dpi that look really excellent.

And remember that it's *camera-original* pixels per inch that matter;
just resizing in photoshop doesn't magically increase the information
present in the image. (Yes, for extreme enlargements there are
situations where step-resizing in photoshop is better than letting the
printer driver deal with it; I'm trying to keep this simple since this
guy seems to be relatively new to this stuff.)

Have fun! Digital photography is *just great*!

Memory cards have become quite inexpensive. I just bought two128 MB smart
media cards, for less than $30 each after rebate. That is cheaper per shot
than film, even if I only used a card once. Over the life of the card, the
cost per hot is negligible. I suggest that you only use TIFF format for
photos of subjects with much detail, and where you plan to make large
prints. The loss in compressing .jpg files moderately is not noticable in
most cases.

You can take one-second exposures, with cameras that let you make the
exposure settings manually. Exposures of more than about 10 seconds are
problematical, because of buildup of noise in the detector. There are ways
to reduce the noise, but not eliminate it.

That is true for viewing on a computer monitor. For prints, you set the
print size yourself. Prints at 300 dpi (or 250 sometimes) are
indistinguishable form photographic prints. Even prints at 200 dpi are
satisfactory for many folks.

Pixels and dots are different things. A printer may make several dots for
each pixel.

When you start to shop, there are some Web sites with good info on cameras.
One is www.dpreview.com.

At the levels used to check carry-on baggage, there is no damage. Never put
a camera, or anything else of value, into checked baggage, which may be
opened for inspection. And the methods to test checked baggage could damage
memory cards, or film.
