That was probably the case a few years ago -- but today -- with
the price of cards so low - there isn't near the "cost" for shooting
hi-res/low compression there used to be.


Cards have gotten so cheap that one might justify simply sticking in a new
card when the old is filled up, because the cost/frame is not much different
from that of film.

There's also the option (actually the necessity) of dumping the card to
disk. I try not to let too many linger there, in case something happens
to the card, or god forbid, the camera. Even at that, with a one gig
card and a 7.something megapix camera, that's a hundred or so
shots...even with the odd mpeg mixed in.

Sure beats the old days when the choice was between a 12 or 24 exposure
roll.

The cost/frame equation falls completely apart when you realize that
unlike film, you can reuse the card. Why anyone would store anything on
one for any longer than it took to get to a computer is beyond me.

Of course it makes sense to understand the tradeoffs -- and choose
the right resolution / compression for both the subject and the target
media. But since I don't always know that in advance -- I tend to keep
my camera at 2048 X 1536 and compression at minimum (though I can
set it to none, I can't tell the difference).


My experience as well; but I admit my camera's not that great.

I periodically dump my cards to an external hard drive. However, I don't
wipe the card until it's full.

Why? Well, it doesn't hurt to have two copies of something. Also, flash
cards have a finite number of write/erase cycles. I think it's tens of
thousands of cycles, but it seems to me that the less often you write to the
card, the longer it's likely to last.

There is also the matter of having prints made at Costco. (I don't use an
inkjet printer. Costco is better and cheaper.) It's easier to pull the card
from the camera than to copy the image from the hard drive back to the card
(assuming it's a "recent" photo).

Point well taken - in fact can be extended by noting it's usually easier
to change cards in modern cameras than film traditional cameras in most
cases.

Sure beats the old days when the choice was between a 12 or 24 exposure

Indeed - plus bracketing - which used to be only for those shots where
there truly were (usually) very poor or unusual conditions - now it's no
big thing to bracket a half dozen and an equal number of composures of
the same subject. On glimpsesofmeridian - I've posted a handful of the
train pictures - out of a choice of nearly a hundred. Some of the
hand-held night shots are totally trash. but as can be seen - a couple
came out pretty decent.

Composures?

Given the appropriate software, bracketed shots can be combined to produce a
picture that shows detail in both the highlights and shadows, over a
ludicrously wide brightness range.

Even my admittedly poor camera has a mode where it will shoot bracketed
exposures, three of them for each shutter press, at a selected bracket
of +/- .5, 1.0 or 1.5....automatically. I've seen some instruction on
how to combine the shots in layers to bring out detail in shadowed
areas, without washing out the same in brighter areas.

The effect is almost surreal...like a video game scene.

My thought, although I haven't yet tried it yet, is that much could be
done by saving the same exposure several times with various settings of
gamma and/or brightness, then layering back the copies to the original.

The only software I have to do that is Corel Photopaint, although I just
downloaded a copy of GIMP...freeware, but highly recommended.

That's the "usual" as trying to get many more without you (or the scene)
moving gets problematical.

Photoshop has provisions to not only work in areas - but to handle
shadow, midtone and highlight areas separately; lightening / darkening /
increasing and decreasing saturation - and you can select to apply
either to the entire image or specific areas. Add that to the ability to
handle layers each with such capability - and you can do some pretty
neat stuff. Fortunately - Minolta (and the successor Sony) has a
multizone exposure system that usually does a pretty good job of
"getting the details". Of course like all such "stuff" you can tell it
to mind it's own business and either use simple or totally manual
controls as you wish. Sometimes in very low light - it's better to shut
the autofocus off and do it by hand - so you get the exact subject in
focus - rather than the camera guessing at what is supposed to be in
focus. In good light - it's not a problem - as the lens is (usually)
stopped down enough to get everything "good enough" - but when the lens
is wide open - it's time to give the automatics "the boot".

The effect is almost surreal...like a video game scene.


Yeah - that's something I have to watch - sometimes when "tweaking" - I
can get a bit overboard - and need to quit "pushing" things before they
become "unreal"...

My thought, although I haven't yet tried it yet, is that much could be

You could - but sometimes it's better to do a transformation of the
original by the values (usually of some specific area) of the brackets
(or tweaked copies). Photoshop let's you have best of both worlds - as
you can apply a layers as a transitional mask (add, subtract - or even
multiply or divide depending on effect desired). Then if you screw it up
- you delete the layer - and the original is untouched.


The only software I have to do that is Corel Photopaint, although I just
downloaded a copy of GIMP...freeware, but highly recommended.


Fortunately - since much of my work requires Photoshop and several of
it's siblings - I "get" to use Created Suite which has all the "toys". I
use mostly Photoshop and GoLive (web work) though I find myself using
Illustrator more and more lately as I work in more technical "stuff".
I also have the "non-suite" package Adobe Audition - which used to be
"Cool Edit" for working with audio like Photoshop does graphics.

Note that, for this to work optimally, the camera needs to be on a tripod,
with the focus and aperture the same for all shots.

Optimally, perhaps, but as fast as some cameras are - they can rip off
three shots fast enough to not matter. The new Sony SLR based on Minolta
technology can rip off shots at 5 FPS at it's full 12+Megapixel
resolution -- that three shots (bracketed) in .6 seconds... And with the
camera's "anti-shake" systems - the field won't move (the subject might
- but a tripod won't help in that case either).

Correct. But you still want the aperture to be the same. If you're
bracketing +/- two stops (which would be normal for capturing a wide
brightness range) and the camera is set for Program, the aperture might
change.
