BW forum queries, re: Canon D60

Canon D60 users, help. Is the D60 useful beyond portrait 
applications? Much as I love my EOS1 and 1N, they are pushing 10 
years of fairly heavy use. I like best about them their reliability, 
sturdiness and speed. How does the D60 compare? For example: could I 
shoot the equivalent of eight 36-exposure rolls in a smoky, dusty 
calf-branding session; the equivalent of four rolls using available 
room light on a woman and her three dogs and cat; the equivalent of 
six rolls on a mother-baby series during a three-hour period. Does 
the D60 work in freezing temperatures? How about in low light? (I'm a 
dedicated 400 shooter. Sometimes 800 and 3200.) I could cheerfully 
say goodbye to processing, squinting at negs on a light table, and 
excruciating scanning sessions. Generally, the Piezo-MIS FS prints 
I'm getting please me, though I detect areas of posterization 
sometimes. Would digital capture eliminate this? Guidance needed and 
welcome! Carol

A good place to start is on the following site (a huge and excellent 
site with more than 1200 pages):
http://www.luminous-landscape.com/index.html  There, you will find 
interesting material on the D-60 as well as numerous links for 
further research on this subject.

This site is a must for anyone interested in serious photography.

Carol, it's not a pro model camera, but has higher resolution than any
of the pro models. 
I certainly wouldn't carry mine in a dust filled room, nor would I carry
any other camera in such a room, unless everything but the front of the
lens was wrapped in a plastic bag.  Quality for 13x19 inch prints equals
film with the D60. D60 only has ISO 1000, not 1600, but you could set it
for -1 stop exposure, (ISO 2000) and work it out in photoshop. I've been
using a D30 for about a year and love it. My D60 should have been here
by now, but they always say in just a few days .... I've never seen
posterization with my D30. It's great for portraits, the D60 will be greater!

RE: [Digital BW] D60 info request

Hi Carol,

One of the best places to read in-depth reviews of digital cameras is
www.dpreview.com. Here are their pages on the D30 and D60:

http://www.dpreview.com/reviews/canond30/
http://www.dpreview.com/reviews/canoneosd60/

It sounds like a Canon EOS-1D might be more up your alley (if price is no
concern!):
http://www.dpreview.com/reviews/canoneos1d/

The 1D is environmentally sealed and quite tough, based on the EOS-1V film
SLR. It can shoot in ISO sensitivities from 100 to 3200. It has a 4.48 Mp
CCD, and its focal length multiplier is only 1.3.

Hope this helps!

Darren.

Wapitiwilla, 

I agree with JerryO here....on every point.  

And....you sure know how to write a descriptive list of scenarios.  Birthing, funerals, weddings, birthdays, I am sure the D60 will make you happy.   Just be prepared to "change" your thinking to digital.

Hi Jerry,

Equals WHAT film?  Not ALL film, that's for sure.

For a 13 x 19, the D60 gives you 162PPI to the printer (3072 / 19 = 162).
For scanned film you'll get a lot more than that, and it'll be quite usable
with a decent film.  The Bayer pattern gives you far less color information
than film (though it's really not that bad, but it is degraded somewhat),
and for grayscale, the Bayer pattern isn't nearly as good as film.

Now, don't get me wrong...it's a great camera, and you'll get great images
from it...but I challenge the claim that it'll give you a 13x19 same as film
in all circumstances, because it won't.  I have a TRUE color 9M pixel sensor
camera (it is a scanning camera, so I get REAL RGB pixels, not the %50
Green, %25 Red and %25 Blue that the Bayer pattern sensors give you that
gets interpolated to give you 6M INTERPOLATED pixels), and the 13 x 19s from
it aren't as good as I get from film, in most all instances.  That, of
course, depends on the film, development and exposure.

Hi Austin,

Certainly NOT!

Austin, you obviously see quality in scans I don't see. My D30 gives me
extremely sharp, detailed closeups. It equals provia 100, or supra 100,
or Reala 100 etc. I've made the side by side tests. I much prefer the
digital, even the D30, which was used for comparison to the film prints.
I did this before I even bought the camera, when I downloaded some D30
files at full rez. This does NOT hold true for landscape photography,
only closeups with my canon macro lenses. Believe me when I tell you the
13x19 inch print is great.  I just don't care what the technical data
says. I have the prints, and I know what I see. I know that the D60 will
be much better than the D30, and I'm completely satisfied with the D30,
for closeups. I'm quite sure the D60 will give me the results I need in
landscape photography.  Remember, I'm only talking about 13x19 prints. I
don't know what the quality would be in huge sizes. Certainly not as
good as scanned film, I'm sure. 

When you rez the D30 up to 240 DPI for the 13x19 inch prints, I really
can't see any loss in quality. You say there is, in detail, that it just
can't be as good. The calculus professor can prove a bumblebee cannot
fly. But it does.  

I am happy with the camera, and I guess this is all that matters to me.
I'm sure I'll be happier yet when my D60 gets here. It STILL isn't here,
and I ordered it 6 weeks ago.

No, I never EVER said in all circumstances. I'm talking closeups, ( Cat
portraits), and Extremely sharp lenses here. There is a big difference
between Top grade glass and average lenses, and it really shows up in digital.

Of course.  Line art images are extremely sharp too, but they have no detail
or tonality ;-)  To me, sharpness isn't an indication of "good" or
"quality".  If there were tones in the original image that aren't duplicated
in the recorded image, information has been lost...though the image may be
very sharp.

> detailed closeups. It equals provia 100, or supra 100,

What size prints?  For a 4x6, no doubt, and for even some 8x10, but for a 13
x 19, well, been there, done that...have some on my photo board.  Not even
close.

> Believe me when I tell you the
> 13x19 inch print is great.

It depends on what you mean by "great".  It WILL be sharp, but it WILL not
contain the same detail as a print made from film.  It physically can not,
and really doesn't.  I've been doing this (digital imaging) for a long time,
and I have a number of digital cameras.  I know the results.  The D-30 isn't
magic.

Same here.

If you believe it works for you, that's good!  I am not saying it doesn't
work for you, as only YOU know that.  But, I'm saying your conclusions as to
"quality" aren't the same as mine.

> Remember, I'm only talking about 13x19 prints.

Me too ;-)

Well I CAN see the loss in "quality", as well as many other people can.  If
sharpness is your primary indication of "quality", then you're going to have
a different conclusion than someone who has some other property as their
primary indication of quality.  "rezzing up" an image does NOT provide
detail that simply is not there in the first place in the recorded image.

> I am happy with the camera, and I guess this is all that matters to me.

Bingo!  And that's what matters to you.

> No, I never EVER said in all circumstances. I'm talking closeups, ( Cat
> portraits), and Extremely sharp lenses here.

There's actually something "funny" about that.  Sharp lenses mean nothing on
this camera.  The issue is there is a "low pass" filter (some call it
"anti-aliasing" filter) between the lense and the CCD.  Why this is
important to understand is this filter actually "dumbs down" the lense so
the MTF of the lense matches the CCD pitch.  The sharpness of the lense, on
that camera, really doesn't matter...you'd probably get equally as good a
result with a Sigma or Tamaron etc. lense, than a high end piece of glass,
as far as "sharpness" goes that is.

> There is a big difference

Actually, that's is not true, as I stated above.  Most of the web sites that
talk about this stuff acknowledge this readily.  Even DPReview says that the
D-60 is probably the first digital camera (as far as the 35mm-esque
varieties) that the lense might actually matter ;-)

Re: [Digital BW] D60 info request

Austin, I have Canon macro lenses, and also the 28-135mm IS Canon.

And I can tell you for a 100 percent positive certainty that the macro
lenses are sharper. There is absolutely no doubt whatsoever about this,
and it is consistent from image to image. The difference is very
noticeable particularly in closeups. The zoom is quite good at far to
medium distances, but the canon macros with floating elements are
better. Even at infinity. For closeups, the macros are much better.

RE: [Digital BW] D60 info request

2002-05-23 by Austin Franklin

Hi Steadman,

I know that the Canon D30 and D60 use a CMOS imaging sensor, not a CCD, but
that's not relevant to any of the comments I made.  Everything I said is
applicable to either.

I typically say "CCD" rather than "CMOS chip" etc., as most people know that
a CCD refers to the imaging sensor.  In most cases, and certainly in this
case, the discussion applies to both types of imaging sensors.  "CMOS chip"
does not necessarily refer to an imaging sensor, as CMOS is simply an IC
manufacturing process, and many other "chips" are CMOS (probably most in the
camera in fact), but CCD is pretty much universally referring to an imaging
sensor.  Perhaps I'll simply say "imaging sensor" next time for amorphous
accuracy ;-)

lenses and print quality (was RE: [Digital BW] D60 info request)

2002-05-23 by Sam A. McCandless

Is a functional equivalent of this low-pass/anti-aliasing filtering 
also occurring when film is scanned? Will we also, for example, not 
get the benefit of the best lenses and the best film if the film is 
scanned on, say, Polaroid's SprintScan 4000 but begin to if it is 
scanned on the 4000Plus or an Imacon or a drum scanner?

I think I've seen it said on another, scanning list that in the best 
35mm films there's detail down (up?) to about 6000 samples per inch, 
but I'm not sure resolution is the issue. Whatever the limits of film 
are, I'm curious to know how to relate them to lens quality, scan 
quality, and print quality.

Hi Sam,

Not that I am aware of.  There is typically IR glass, but that isn't the
same thing.  I know of no low-pass/anti-aliasing filter used in my scanner.

I would agree with that.

No, it typically isn't.

Can you narrow the discussion down a bit...that's a very broad topic, with
lots of tangents, loop-holes and caveats ;-)

A long time ago I called Kodak's digital division and asked a few
questions, one of them being, how many pixels would it take to equal the
information on a Kodachrome ISO 25 film. He said 12 million pixels would
equal Kodachrome. Don't know if this is still true, but he seemed to
know what he was talking about. That was years ago when a 12 million
pixel chip was only a dream.

Austin, on this one I really disagree. It is extremely obvious that the
canon macro lenses are much sharper than say, the 28-135 IS Canon Zoom
lens on my D30 Digital camera. Anybody can easily see the difference.
Even at infinity, to say nothing of closeups. This is very consistent,
from image to image, and I've tested the two lenses many times on the
same subjects.

Hi Jerry,

That claim doesn't match their Kodachrome 25 data sheet, and there are many
issues that are really misleading WRT that claim.  Do you know the persons
name?

Your camera uses a Bayer pattern "imaging device", which does NOT give you N
mega-pixels (what ever the spec says).  It gives you %50 green, %25 red and
%25 blue.  The camera software interpolates that information into giving you
N mega-pixels out of the camera, but the sensor is NOT an N mega-pixel
sensor.  Color film does not have this issue, it has color information for
every "spot" on the film.

The resolution of Kodachrome 25 (which, BTW, is not near as good as modern
films), according to Kodak supplied data, at a contrast ratio of 1.6:1 is 63
lp/mm, and at 1000:1 is 100.  So, let's say it's 75, since the real number
that represents practical reality is somewhere between that.  That gives an
equivalent resolution of 150 x 24 x 150 x 36 or 19,440,000 TRUE pixels.
Better films are substantially more than that.

Regards,

Austin

Well that sounds about right, but this must have been about 8 years ago
at least! I think I will be delighted with my canon D60. Canon says they
were released in March.  Where in the world were they released? I've
called all over the place and cannot find anybody with one in stock.

Oh, I am SURE you will be!!!  I would be too ;-)  I tend to do mostly MF B&W
work though, for which digital cameras don't give me the results (at this
point in time) I want, but I certainly would consider a full frame digital
camera that had a film equivalent (as in used the same lenses), and had
decent FAST lenses.
