Well, I don't own a good digital camera. When I'm in Chicago, where I
do most of my photography, I borrow my nephew's Nikons. g


O.K.

I thought that some of them will take multiple exposures? Again, I
don't own a good one, so I don't know.


Some will. I think that my D300s will do it, but I have not
needed that feature so far, so I tend to forget. Time to re-read the
manual, I guess. Always good to do after using the camera for a while
to pick up on things you missed earlier.

With film, I try to do it with one of my two cameras (Calumet 4 x 5,
and a Yashicamat 6 x 6) that allow it without moving the film. My F2
won't allow it; they started that with the F3.


Or -- put a lens with between=the-lens shutter on the camera on
a bellows, and you can do it with the F2. :-)


Yes, but jeez....


:-)

You'll get a kick out of this. I have a behind-the-lens air-bulb
shutter I used with process lenses on my view camera, which I used for
making Tri-Mask in-camera separations for the Trenton Times. I have
put that sucker in *front* of a lens on my Nikon F2 for shooting
multiple exposures. It's a big interleaved shutter.


That will do it. Or an electric shutter such as I used when
building a camera from a large lightbox to 2x2" glass film -- for
integrated circuit layouts.

Though usually I was running the lightbox on a Gralab timer
instead. :-) The lightbox was two neon transformers and white neon
folded in square-wave shape behind a diffuser.

But I don't get into those gymnastics anymore.


Understood.

However, I did a series of nightime architectural shots, for a
portfolio, with my F2 and a 28mm shift lens.


Ah -- the PC-Nikkor.


Yeah, one of them. It belonged to my partner at Windsor Advertising.
He had a gazillion lenses -- and an 8 x 10 Calumet that we used to
shoot giant trade-show Translites for Canon calculators and Prince
tennis rackets. They were around 20 feet wide.

Those were fun times.


Indeed so. My largest format at home is 4x5 -- both a view
camera and a Crown Graphic (like the Speed Graphic, but without the
focal plane shutter.) Yes, the 8x10 Calumet was what I used with the
same light box for printed circuit layouts. Two color layout tapes, and
filters for the two shots for the two sides -- we didn't try
multi-layer boards. :-)

'Second that. I even use one for doing test shots, to balance the
lights, when I'm doing the final on 4 x 5 film and using a Minolta
Flashmeter IV for exposure.

So you have not depended on the results from the digital, except
as a rough guide -- so you may not have seen the effects of the long
open shutter time, since you probably did not bother blowing up the
image on your computer monitor.

Actually, for that Amada brochure, I wound up using the digital shot
from a Nikon D5000.


O.K. A bit out of my price range. :-) That and the single-digit
D series. :-)


[ ... ]

Was this a single shot, or a multi-flash one like the above?
For single shot, I would expect the D5000 to be very good.


A single shot with my (then) new Smith Victor daylight fluourescent
scoops. I was using too many new things at once not to have backups.

I have the digital shot on my hard drive if you want to see it --
before and after I worked it over with Gimp.


You could not get it to my mailbox. There is a size limit of
60K (to keep virus e-mails out of a couple of small mailing lists I
host.)

Of course, with the Nikon gear, and a shooting budget, I would
go with the Nikon and a cluster of SB-800 flash units. The camera can
be set up to run all of those as a slave, and when you take the shot, it
first fires a lower intensity pre-flash from each (triggered by the
flash on the camera and metering it in the sensor), and then sends to
each how long a flash duration is required from that one, so when the
shutter finally opens for real, you get a properly balanced
illumination. I've got *one* SB-800, but not a whole herd of them. :-)


Again, I spent too many years lugging 100 pounds or more of flash
heads and power packs, and even my big Bowens Monolights into the
field. No way, Hose-A.


The SB-800 flash units are very light -- often used camera top
on 35mm SLRs. A camera bag with a half dozen of them would be lighter
than my bag full of lenses. You can clamp them pretty much anywhere, or
just set them on a tabletop. And no wires to string -- the camera and
the flash units communicate by encoded flashes. :-)

From now on, I'm going with the daylight
fluorescents. Lots of field photographers are using them now. I'm
convinced, after seeing the densitometer readings on digital images
from my gray card and Macbeth Color Checker. I shot the latter in
daylight and then in daylight fluorescent with the same camera. You
can hardly tell the difference.


Pretty good, then. But probably about the same weight per head
(for just the lamp and the socket) as the SB-800.

I'll buy a good digital some time, but I haven't had enough need to
justify it. I don't shoot for fun like I used to, and I haven't shot a
magazine cover for around a decade now. I rent when I need to.


While I'm back into shooting for fun. For quite a while, I
worked where classified stuff was common, and a camera was a no-no, so I
did not take many shots during that period. Now I'm retired, and having
fun with the digital SLRs from Nikon.


It's a great hobby. Maybe if I retire I'll take it up again.


I *am* retired, so I did. :-)

Enjoy,
DoN.
