Digital Issues

2003-11-14 Thread Collin Brendemuehl
I'm wondering more about trade-offs than advantages.
There's some real losses with digital.

For instance, CD-R media is showing itself non-durable,
with some media only retaining data for a couple of years.
Indexing systems are sparce, mostly inadequate.
(I'm going to purchase a laptop this next month and create one -- 
a professional one.  Finally.  Period.  $5,000.
It's been designed but just not built & tested yet.)

Few have reliable tape or CD-R backups installed.
CD-R backup s/w for Win is about $50 & media is dirt cheap.  
Do it at least monthly.  Weekly is better.
DLT tapes don't cost that much and are practial as well.

In that light I've designed an imaging system that 
accomplishes more than you could imagine.
It's 24x36mm, holds 60 million pixels of information 
with unlimited color and gray-scale levels,
the media lasts 50 to 150 years,
take no hard drive space,
are thinner than a potato chip,
cost about 10 cents per image capture,
and
is retrieved by simple optical scan.
2 1/4" & larger cost more per image capture 
but all are handled in the same manner.

Should have saved this for April 1.

>i have a minor problem once every 6 or 8 months. the printer is always
turned off when not in use for more than about 15 minutes. this caps the
heads and preserves the ink. i also print at least once a week because that
is how often i have a batch of photos to print. i have concluded that i wore
out my Epson 1270 printer by printing so much that the carriage friction
wore irregularities into the rail and caused mistracking of the head.

That's useful to know, thanks!

Just turned off printer -- it was turning on every time I booted.

You might consider the Minolta Scan Dual III for under $300 new.  Check the
reviews on this scanner and I think you'll find it is rated quite highly.
No, it's not a perfect solution, but does offer the digital world to many of
us at an affordable price.  Since I own this scanner I am finding it quite
hard to justify a DSLR at this point, since a good share of my motivation is
controlled by my Wallet!

Not really.  You can get decent results from a dedicated film scanner
at around half the price of a *ist-D/D100/10D (or something quite close
to the price of a 300D), but the cheaper units are usually just flatbed
scanners with transparency adapters, which don't work as well.

Then, of course, there's the sheer tedium of doing the scanning.  You
can get film scanners with bulk feed magazines, of course, but those
cost about as much as a DSLR.  By the time you've scanned a couple of
hundred frames you'll welcome anything to relieve you of this task.

Next problem; dust.  Unless you live in a semiconductor manufacturing
plant, there's going to be dust on your slides. Cleaning up dust spots
is yet another tedious chore.  You can get semi-automated software and
hardware to help with this task, but this too is not without drawbacks.

And, finally, cost.  I'm sure that many of the DSLR purchasers here
shoot enough that using the *ist-D will end up being cheaper than the
cost of film and processing over the next couple of years.  If you
only shoot one roll a month, and if you are prepared to let WalMart
or CostCo scratch your negatives, then a DSLR isn't cost effective.
Shoot an average of more than a roll a week, though, using slide film,
and take the film to a local pro or semi-pro lab, and the costs mount.

I moved away from film scanning a few years ago after getting sick one
last time of dealing with dust on the slides.  I really did like
shooting slides and viewing them, but scanning them with anything less
than a $1000 scanner just wasn't producing decent results.  I don't
know if prices for good scanners have come down and maybe that has
changed.  I was using a Nikon LS1000.

I think my photography has improved as a result of using digital for a
few years because I can preview right away and tweak the image by
taking it again in a slightly different manner.  The knowledge that
I've picked up from this would probably carry over to film too.

The only film that I expect I would shoot anymore is if my *ist D
died on a trip, or if I was going somewhere that required I carried
the smallest camera possible and then I would take my Ricoh GR-1.

I've had fairly good luck cleaning my Epson heads with a high grade of
isopropyl alcohol.  I simply pull out the print cartridges and take a cue
tip loaded with alcohol and place a drop in the opening of each print head.
I then take a clean dry one and soak up the excess.  Replace the cartridges
and run a couple of cleaning cycles.  So far so good with this procedure.

Whether or not there are any negative consequences to this I don't know yet.
But what else to do?
