Thanks Steve, nice comparison. I hope some of the film fanatics here
see it, and at the same time realize the many other benefits of
digital that go beyond mere resolution. Considering them and your
results, I see no valid reason to stick with film. I see many to
switch to digital.

As you wish.
A conventional camera is cheaper. I don't have to worry about
breaking it. My Minolta 9xi is hanging from my harness and I don't worry
about banging it around, while I'm climbing.
I shoot slides, and I like them projected. There is at the moment no
adequate beamer, which could do the same. Of course, I could make slides
out of them... but then, where is the point?
I don't need to worry about the battery level. A lithium battery holds up
for many film. A replacement battery is light and small. I'm not that
dependent on external powersupply. You know, there are places where you
just don't have a plug coming out of somewhere.
I love wideangle pictures... projected they are awesome. But, you need a
fullframe sensor to achieve that... the price is just not right yet.
Film is cheap. 32 MB x 36 for couple euros, dollars or what ever.
Plus I have a redundant system. If I drop the camera, and it goes down the
wall, the lost of pictures wouldn't be total.
So far, I didn't need to worry, if my pictures are still readable.
I can scan in my picture to have them available digitaly.
And projected slides are just awesome.
Did I mention how awesome it is to watch the slides projected?
So just stop the war digital against film.
There is a point for film, there is a point for digital, and everybody has
to decide themselve, why she/he stays with that particular system.
So far, I'm not thinking about trading my Veliva/Provia with CompactFlash
or other memory cards.
-Leonhard
Why do you have to put it as black and white situation? You probably see not
reason why to still use film, but others may for their own, just as valid
reasons.
Of course you see many switching to digital. If you open your eyes, you'll
see many using both, and if you look carefully, you'll see few returning
back to film. Thankfully the world is still colorful with a lot of variety.

My K1000 just needed a little rinsing off after landing in boulder creek...
It also goes climbing and has taken more out of rock faces than they've

Winter alpine climbing and CC skiing, I give up at -20f but both of my
film bodies work the same at that temp as room temperature. Even if they
fail, I can guesstimate without a light meter and most of the speeds in
the LX are mechanical.

Film doesn't die when dropped in the aformentioned creek - Most any lab can
wash it out before processing with little ill effect.

Thanks for posting that link. While I doubt 4 comparisons will really
settle the issue in anybody's mind, I find the examples shown very
convincing. It probably helps that they exactly match my own

You know, I generally avoid such debates, but I'll make an exception
for the 1Ds.
I've been looking at this camera more and more lately, and I can't
argue that it has better resolution/image quality than 35mm. In fact,
if it didn't cost $8K, I'd probably own one right now(Even at $2k, I'd
probably have bought it by now).
The thing is - I don't handle my photos digitally even though I can.
I have the computer/scanner/etc. but everytime I consider shooting
digital against film, I first ask myself what I'm planning to do with
the image. Most of the time, I'm thinking of making an 11 inch or
larger print to hang on the wall for my own enjoyment and while some
digital can do that well, I wind up using film because I don't want to
spend my time printing/retouching/etc. The pro lab will happily spend
time adjusting the image to suit my needs and can usually do a better
job than I could do digitally. Very few of my images ever see the
internet either, so there again, digital isn't always the way to go.
The one exception is that I do carry a small digital camera with me
for snapshots that I find amusing or interesting when I'm not carrying
my full kit with me. For most of those digital is ideal becuase those
shots will either end up being my desktop wallpaper of the week or
they'll be sent to friends/family on the net.
Ok - so you must be wondering - what on earth would I do with a 1Ds
had I bought it? The only thing I can see going for it is flexibility
in cropping the final image. With the images you posted, it's clear
that I could easily leave half of the resulting image on the virtual
cutting room floor without sacrificing overall quality of the final
image. That means I can leave a 50mm prime on the camera and use
cropping to hit anywhere I want in the 50mm-100mm range without
resorting to lense changes. Maybe when the price comes down and the
resolution goes even higher, I'll be able to shoot with one lense and
one set of filters... (Well, I can dream anyway). For the time being,
medium/large format already has that feature well covered.
--drsmith
Also, can you shoot ten frames per second for a whole roll of 36 with
any digital camera at any price? This feature is a must, I use it all
the time. I don't usually shoot a whole roll, but I do bracket and
shoot 9-12 frames.
Just an honest reply,

Huh?
If you want to always use the same color balance every time, just like
with film, you can easily do that with a DSLR: just set the balance to
"daylight". Most photographers would prefer a color balance that better
matches the scene's actual lighting, though...

Sounds like the camera you want is the Canon 1D (not 1Ds).
But that sort of speed is only usually required for sports
photojournalism, so I'm a little confused why you want to mix it with
bracketing...

You can't shoot "any film camera, at any price" at 10fps either!
I thought the nikon f5/canon 1v were around the 8-9fps mark anyway.
The nikon d1h can do 5fps for 40 frames, though at only 2.7mp. The Canon 1D
can do 8fps at 4'ish mp, but for about 20 frames.

Gavin, I might be wrong, but I seem to recall that Canon made a special
version of the Pellex (the one without the normal bouncy mirror, it had an
in-place pellicle kind of mirror that would optically feed both viewfinder
and filmplane at the same time). It was offered to some pros at one of the
Olympics in the eighties, or the '92 Olympics. That camera was capable of 10
fps, I'm almost assured. Problem was that, in some instances and under the
right conditions, when pointed at the sun for a period of time (don't ask
why), the shutter curtain would have a hole burned through it!

Right back attcha, Pierre, I couldn't agree more w/ you - also, I have for
quite some time been saying that digi has a "high res video plasticky look to
it" - I can see and feel the difference in their looks, others less attuned
visually (general public) would probably be able to subconsciously feel (if not
consciously notice) the difference between the "depth" of film and the flat
plasticky look of video, er, digital... I made a Freudian silicon (or CMOS)

I shoot with a couple of EOS 1v-HS cameras that shoot 10 fps with the
correct battery pack. This means that when I bracket +1/3, 0, -1/3,
the camera will complete the 3 exposure bracket much faster than any
digital at any price.
Your suggestion that this kind of speed is only needed for sports or
photojournalism is way off. Try shooting big cats in the Maasai Mara.
Even though they may be still, they are in the position you may want
for less than one second. In that split second a Leopard looks at you,
it is nice to be able to take as many frames as possible.

Also, your suggestion that I can't shoot 10 fps with any camera at any

Unless you used color balancing filters based on a measurement of the light
source when you shot the slide (do you even own a color meter<g>?), your
slide colors are simply wrong. But every digital camera has a built-in color
meter, so a manual color balance reading with a digital camera will mean
that the digital image will be correct _in the file_, and anyone with a
calibrated monitor can display it correctly. Besides, no one else can see
your slide: there are a lot more people with calibrated monitors than you
can get into your workroom.

You mention referencing the other (slide or negative) before making a
print look similar to another. If you take that into the digital
world, how can you ever reference anything to make a print, or any
other output medium, when you don't have a reference. Viewing a
digital photo on a ten different monitors will give you ten different
photos. If I look at a Velvia slide with 10 different loupes on 10
different 5000K lightboxes, I will get the same result everytime. This
result accurately depicts what is on the slide, not accurately depicts
what the subject looked like (although it may).

Yeah, I’m pretty sure that Gavin was saying that the statement "You can

You should do your research, too. It was Gavin who made that comment,
George corrected him.
Both the digital camera, and images made by scanning film (or a print)
are sampled data systems. Folks over half a century ago determined,
from information theory, the requirements to faithfully sample and
record information. Nothing in digital photography today negates those
half-century old findings. If you sample with a grid commensurate with
the image information you are sampling, you will be able to accurately
reproduce that information. I have seen nothing in this thread so far
that negates that fact, concerning film scanning OR digital cameras.

Hi Lewis,
I could have done that, and in fact I did consider getting a used MX (which
seem to be plentiful around here). The few LX's I saw were expensive even
though they looked pretty banged up, and what limited used Pentax lenses
there are out there are fairly expensive. For that matter, I could have just
kept my still-mint 1986 K1000. To be honest, until recently, I hadn't kept
up with the camera industry at all since that time, except seeing the odd
Canon or Nikon ad in waiting room magazines. I had wanted a digital camera
for the past few years though (even though I decided against it in the end).
There comes a time when you just want something new, and when I started
looking, I was disappointed to find that SLRs are mostly all plastic like
the cheap Kodak compact 35mm I bought at Disney World in the late 80's after
I realised I had left both my Pentax and my Polaroid SX-70 at home. I really
had no idea it had come to this. I considered and tried both a Pentax MZ-6
and a Nikon F80, but when I laid eyes on a chrome FM3a with a 45mm lens on
it, I just had to have it. And, I should add that, being on a disability
pension, this expenditure was pretty much a one-shot deal for me. So I spent
what I had while I had it, before it disappeared on sundries. Whatever I
picked, that would probably be my camera for the next 20 years, so I had to
pick wisely (hopefully). A camera that is obsoleted faster than I can walk
out of the store with it definitely was not in the cards, nor was one that
might soon need repairs - like a new shutter or something.
I actually ran some rolls of film through both the MZ-6 and the F80, using
their respective autofocus and multi-segment exposure modes. I never got so
many poorly-focussed and poorly-exposed pictures in my life. With the FM3a,
it's just like my old Pentaxes. Not one was what I would call a good
photograph, but from the get-go, not a single one was out of focus, and all
were fairly well-exposed (and I checked the actual negatives on my scanner).
My own eyes I can understand even though I know wear glasses to see, and I
also can understand pretty much exactly what a centre-weighted averaging
meter is doing. So far, I don't regret my sticking with a more traditional
camera. I guess I'm still just a 1970's guy living in the 21st century, and
I figured I should buy from the guys who still make a camera for people like
me :)

Yes - they can make a print from a digital file. 2 problems, though.
The first is the print from the digital file is more expensive than
the print from the film - for some reason they market this as though
it's a custom service. The other problem is that I don't keep a lot
of extra CF cards around and if the card/cards is/are in the shop, I
can't use it/them to take pictures.
Just seems easier to hand them a film canister, pay the lower price,
and check the fridge once in a while to see if I need to order more.
Maybe I'll do a more thorough cost comparison in the future...
As for the size issue, I've got both MF gear and 35mm. I do my best
to guess which is the right one for the job - and there again is a
cost issue. 120/220 costs me more to have processed, so I'll be a
little more sure it's worthwhile before I reach for it.

When the Nikon LS-4000 came out I lost intrest in it because test scans I saw
posted had too much softening with ICE enabled so I went with the Canon FS4000
at a bit less than half the price.
I concluded long ago that for me 6 Mpixel would be about equal to film and a
lot more convienent, but I can't live with the 1.5X "magnification" factor so
I'm still waiting. If I could afford a D1s I'd have one.
I could stretch and go for a Kodak DCS 14N when it drops a bit to ~$4000 but

Ok so you like cheap and you like to admire your slides.
Some photogs like to sell images and price is not the advantage either
way. Try pricing some drum scans.
Frankly slide shows are history. If that's your niche, stick with
film. If you just like sitting in a dark room admiring your own
slides, stick with film.
I'd love to be able to extract quickly and easily the quality I see in
my slides too. But in the big picture it is not the way to get my
images to sell, or to make prints to sell.

Ya really, is that Provia colour, Velvia colour, or Ektachrome colour?
I've never seen a film that can show realitic and vibrant colour like
a digital camera can. No way, no how.

My baseline would be the colours I remember seeing an hour ago when I
shot the digital image, not three days ago when I shot the film.
You can say that again. If there ever was vibrant colour in photographs it's
got to be in digital - so vibrant it's totally unrealistic! Has everyone
gone colour-blind or something? Everybody seems to think unrealistically
punched up colour is normal these days, film or digital. Must be something
in the water.
Pierre
Dunno what you guys are talking about. Digital is whatever you want it to
be. I see a lot of flat/dull digital from the dSLRs. It's only if one is
careful about one's color spaces and sets/adjusts saturation that digital
coughs up anywhere near Velvia colors...
My experience indicates that without ICE and GEM, the 10D just blows
away Provia 100 film scans when both are printed to 12X18. I'm aware of
the slight softening of the image caused by these two post scan
processes but that loss is very minimal and doing without ICE and GEM
doesn't really help a Provia F scan compete with 10D output. Velvia,
which resolves more LPM than Provia, would have been a better choice to
produce sharper looking film scans.

You just hit the nail on the head. Film printed to paper is third

the film holder unless you use a glass carrier, which introduces the
possibility of another problem called 'Newton's Rings'. Have you actually
compared a DSLR image printed on a good printer like LightJet or Chromira to
an optically printed photograph? I have, and I don't see where the digital
print 'pales' at all, quite to the contrary....:^) I think it is much easier
to get good results printing digitally.

Yes, my math and concentration were out the window. Film to conventional
optical print is SECOND GENERATION. I can't think of any way you could
compare printed output on the web. I guess a person could scan prints
from a DSLR and optically printed 35mm film but then you WOULD have
THIRD generation stuff to look at...:^) In fact, I think I have seen
this sort of comparison on the web. Sorry, don't know where it was....

Anyways, I too have heard people claiming that prints from a camera like the
1DS are slightly sharper than prints from film (whether 2nd gen or 3rd
because of film scanning, I don't know). However, it's hard to believe such
claims without empirical evidence that I can study with my own eyes. Until I
see otherwise, I'll probably continue to believe that while a camera like
the 1DS is indeed slightly superior to film, with cameras like the D60 and
10D being approximately equal to film (talking scanned 4000+ ppi Provia 100F
of course), the prints from all these methods probably obscure any real
differences (depending on the size of the enlargement of course).

In camera sharpening, using Unsharp Mask in PhotoShop, or similar steps in any
editing software, can create an appearance of a sharper print. Regardless of
the source, many different methods can be used for similar results. The fact
remains that some time and decisions were needed to do the changes, with prior
experience often dictating what works best for each method of printing.

Consider that many comparisons are made from inkjet prints. Because of the high
dot gain of inkjet printing, there is a limit to display of apparent
resolution. A printing target used for commercial press runs (not newsprint)
would show the actual lack of fine detail resolution in the majority of inkjet
prints. Then you are left with judging the images based upon apparent
sharpness, which has much more to do with edge contrast than resolution.
Images printed on a commercial press are capable of greater spi (signatures per
inch), though will only display fine details if the original file contained
that detail. A good example of this from the world of scanning: take two files
of exactly the same size, with one as a drum scan, and the other as a CCD film
scan; and you would find that the drum scanned file gives greater edge
definition, and better rendition of fine details. The ability to discriminate
various hues is better with drum scanning, so the appearance result is finer
detail display, but only apparent with some types of printing. If you printed
both those same files on a desktop inkjet, you would likely see little to no
difference.
Basically, if your concern is to printed quality, you should find out the
limits of the printer first. All you need to do is match the capability of your
printer, or printing method. If you have more information in a file than what
your printer can display, then the extra information is wasted. It might even
slow your workflow down, since the file size could be larger than it needs to
be for the results.
Also, consider that any adjustments you do in most editing software are
destructive, similar to "generational" losses. There are software applications
for image editing that can maintain the majority of the information as intact,
but they are not as common as PhotoShop, and many are quite expensive. Anyway,
any steps you can do to a digital file direct from a camera could also be done
to any file from scanned film; it would be easy to "sharpen" either, and claim
one was sharper than another.

Once the image is projected by the digital projector, you're lucky if
the image is 10 PPI on screen. The PPI value that the computer monitor
would display it at is irrelevant.
The real problem is lack of pixels, which results in lack of resolvable
detail. A projected 35 slide has a resolution equivalent to at least
3072x2048 (6 megapixels), possibly much more depending on camera and
projector lens and film choice. A typical digital projector is about 1
megapixel, and completely inadequate for showing the detail in a 4 or 6
megapixel digital image.
Even HDTV equipment, still horrendously expensive, is only 2 megapixel
(1920x1080).
For the moment, if you want to project high-quality digital photographs,
there's not much choice other than recording them back onto film and
projecting the film.

The Minolta scanner looks VERY promising, not only does it have 5400
dpi resolution, it also has hardware based grain reduction. Too bad
I'm stuck with the lousy Canonscan FS4000US that makes all film
emulsion bubbles show up as dark black specks :(
It's a totaly valid comparison...
if your intention is to project your pictures.

1. No film cost. Sure the camera is three times more expensive but it
eventually pays for itself, especially if you shoot alot. I shot over
3600 pictures one weekend for an AVP event. Using the cheapest film it
would have cost me around $200 for film alone.
2. No developing cost. Sure, you need a computer but who doesn't have
one nowadays. If you are a photographer you surely have the tools
already. The aforementioned AVP outing would have cost me a minimum of
$400 in developing cost.
3. No developing wait. Shoot ... go home ... download ... view. I can
be viewing pictures in as little time as it takes to get home. If I'm
shooting film it's a bare minimum of 1 hour, not including time to get
to and from the lab.
4. No sitting by a scanner for hours on end scannind images. I've got
a Nikon 4000 and I know that it's full resolution scans are not really
quick, especially if you need one of the ICEÅ‚ components. I've found
that dust & scratch removal is almost always necessary and that
doubles scan times. Add in grain reduction for a high speed film and
it's tripled.
Just that one AVP shoot would have cost me a little under 1/2 the
price of my 10D. So, that camera has almost half paid for itself in
savings over one weekend. Too bad I've also got a 1D so I've got alot
of shooting to do to pay for both of them ... and all my L glass.
Sure, I know there are alot of other variables but all in all and over
time a digital camera will be cheaper to use and quicker to get photos
from.

Mike, what is an "AVP" event and how are you printing your pictures; 4x6"
chemical prints, inkjets or dye subs done on spot or later/after the event by
you at home/office?
TIA

Lewis

"Association of Volleyball Professionals" It's the USA's Pro Beach
Volleyball Tour.
Any pictures that I want personally I print on my Epson 1520
(hopefully soon it'll be a 2200). For the shots that some of the
contestants bought I uploaded them to Adorama's print lab and had them
do it so I know they'll be lightfast and will last.
If you're interested:
www.wideopenphotography.com/photos/avp/avp_index.html
As it is, there are over 1800 pictures on that link, after deleting
all the "missed shots". I posted them all because I got many requests
from players asking "how to get them" so I figured if I'm gonna sell
them I'll give them all the pictures to choose from.
Look through "The Good Shots" links to see all the quality photos.
When I eventually get around to it I'll take some of the good ones and
make a gallery, combined with a bunch of my other "good ones" and
actually develop the site. But, I can't seem to find the time ...
Thanks for the explanations and the URL, MIke :-)
