> Tell me Karl, since I was last here, what has changed with digital?

for what it's worth, I've seen knowledge evaporate, reliance on technology
take a stronger hold and interest in the underlying principles decline.
I've seen my pet hate, myths, perpetuated, I've seen manufacturers spreading
lies and I've seen good people decried for their lack of 'insight' in
regards the future.

I've seen photographers working harder, taking more pictures yet getting
less successful 'hits'.  I've seen good cameras and lenses being swapped for
annually disposable auto-everything's.  I've seen frustration and confusion
over software and a dependence of  *graphic design* software being used by
photographers.   I've seen graphic designers, multimedia types, mums and
dads step into the arena depriving photographers of work.  I've seen jobs
simply cease to exist.  I've seen people passing through college who leave
with advanced diplomas who know nothing about exposure, light, optics,
calibration.. nothing about rendering and realism.

I've watched a steady increase in colour casts appearing at all levels of
photographic output.  I've seen green people, asphyxiated blue models,
magenta kids playing with magenta dogs.. sometimes I've seen magenta parents
in the same ads as their green parents!  Looking at the increase in small
headed folk with huge feet appearing in images with those cursed with
noggins of gargantuan proportions one can only conclude that the rate of
birth defects is up too with the prevalence of digicams!

That's the grounds on which the digicam manufacturers choose to mount their
campaign and on that ground they have won.  they could have been drawn to
other territories and rational debate could have followed, but no, it was
not to be.

Where is the IR photography these days, stuff anyone could have managed with
a 50 year old camera?  Of IR only the Sony's seem to have had the foresight
to allow one the full advantage of CCD's inherent IR sensitivity, but at the
cost of relying on autoexposure.  One can mimic it digitally, but heck, it
is NOT accurate across the spectral range *known* to film.  Where are the
manufacturers specifications??

I see the newest HP digicam no offers inherent red eye removal.. I suppose
the algorithms look for red dots surrounded by white set against a certain
range of skin like tones.  itd be interesting to see what else these cameras
'correct'.  Algorithms can pop any level of detail in an image, and they
frequently include stuff that was not there.  interpolation is a wonderful
thing :-/

Since that was all you ever saw Bob I see no point in following this line of
reasoning other than to increase download speed.  The images you've seen on
your monitor are digital.

Remember the National Geographic shoot that raised havoc some time last year
when the kingfisher was deemed to have been imposed on the image?  It is in
the eyes of the wider public a legitimate shot.  A carefully crafted shot
will confuse many to the point that they will not question it..  but it has
to be so carefully crafted that doubt will not exist.

Laugh..  some do !
