When I was a kid, my parents and I took a bus tour through British Columbia, and ended
up at the construction site of the Bennett hydro-electric dam in Northern BC. I
had a Grace 126 snapshot camera with me, and took a couple of dozen pictures. The photography bug bit, and as of
today, I have well over 3,000 slides and negatives. My current film-based camera
gear includes two Minolta XD-11 35mm SLR camera bodies, various lenses from wide angle to
zoom, a Vivitar 285 electronic flash, various filters and special effects devices, and a
tripod. I shoot mostly colour slide film (Fuji 100 ASA), so I also have a good quality
projection screen, as well as a Zeiss Pradolux RT-300 slide projector. This combo gives
superb images, due to the precise Zeiss optics in the projector and the matte finish on
the screen.
In the 1970's and 1980's I equipped myself with a decent darkroom, including enlarger and Cibachrome positive-to-positive chemicals
and papers for colour work. In the ensuing years, I did many colour enlargements of my slides
using this setup, as well as some black and white work. In many ways, the black and white
was much more enjoyable, since you can see what you are doing while the print develops in
the trays before your eyes. Cibachrome (and the other colour processes) all require more
of a cookbook approach to print development - consistency is the key. In any case, I became
quite proficient in darkroom work, and took good advantage of my formal darkroom training
that I received from BCIT in the Photogrammetry lab. Today, I have many enlargements hanging
on my walls and in my files which are the result of this darkroom work, however I
eventually
lost interest in conventional darkroom, sold my gear, and moved on...
I purchased a Microtek ScanMaker 35t Plus
slide
scanner in late 1996. My first choice was to purchase a digital camera, however the market
(at the time) was still
developing new technology for these devices. I therefore decided to
continue to use my 35mm camera setup, and scan slides
and negatives where needed.
A digital camera which delivered equivalent quality to my slide scanner cost
tens of thousands of dollars (at the time). While I waited for the market to
catch up to my demands, I developed my skills in working with
digital photos on my computer system using this setup.
Nikon Coolpix digital
cameras
I finally decided to take the plunge and purchased a digital camera in October of 1998
- a SVmini-209.
I had so much fun with this (fairly limited) digital camera, that in July of 1999 I purchased a
much more capable digital camera - the Nikon
Coolpix 950. My 950 became my workhorse camera,
traveling with me everywhere. I ended up taking over 3,000 photos with
this camera between 1999 and 2002. In 2002 I
decided to upgrade to another digital camera from Nikon, the
Coolpix 4500. The 4500's systems were completely
redesigned by Nikon, and offered me some features I could make use of for my
interest in Astronomy and
astrophotography.
The Nikon 950 was a best-rated 2 mega-pixel
digital camera with a 3x optical zoom, and
the Nikon 4500 was a best-rated 4 megapixel digital camera
with a 4x optical zoom.

Some sample

Trip to Vancouver - features some dramatic shots of the cityscape
I took
using the Nikon 950. I used a Tiffen Circular Polarizer filter. The deep blue
skies, luxurient green foliage, and lack of spectral reflections off the
glass and metal enhances the look of the images by increasing the colour
saturation. |
At the time I purchased the Coolpix 950, I
thought it was time to retire my two Minolta XD-11 35mm SLR
film-based cameras Virtually all the photos I
took since getting the
two digital cameras have been
digital photos, so it appeared the trend
was set. The Nikon Coolpix cameras opened up my creative side, since
they were such capable digital camera
systems. It was so liberating to not
have to worry about film. Images
load directly onto my computer's hard drives from the
digital camera. This feature become very attractive to me, and being able to post images to my
website the very same day that they were taken is an intangible benefit of
digital photography I hadn't fully appreciated previously.
Nikon Coolpix 4500 digital camera built on my experience with the
older 950. I found several features in the 4500 that lent themselves to
astrophotography:
 |
noise reduction (aka dark frame).
This was one of the first consumer digital cameras with this feature.
|
 |
CCD sensitivity can be set to a choice of ISO
100, 200, 400 or 800.
|
 |
long exposures of up to 5 minutes.
|
After performing some
Dark Frame Tests
using the 4500, I realized this camera was indeed very useful for
astrophotography. Of course, it is was also a very capable camera for normal
photography as well. The Nikon Coolpix 5400 is a very nice
point-and-shoot digital camera, with many improvements over the design of its
predecessors, the 950 and 4500. I took this camera with me when small size
was required, or when I just wanted to take some snapshots. This camera's
design didn't lend itself to astrophotography, however I had that covered
with my other Imaging Hardware.My Nikon Coolpix 4500 digital camera was
stolen from my checked bag while I was on a flight from Auckland, New
Zealand to Victoria, BC, Canada on May 21, 2004.
The
Canon EOS 300D Digital Rebel digital SLR
camera was my first Canon camera, but it came highly recommended by astrophotographers around the world
since Canon used the best low noise CMOS sensor
available for this camera and its bigger brother the 10D. I also
used this camera for normal terrestrial use. Having used point-and-shoot
digital cameras for the previous few years, I hadn't realized how much I missed
using an SLR. They have fewer limitations and design compromises as
compared with point-and-shoot cameras, providing the photographer with so much
more flexibility and ease of use.
I sold my Digital Rebel after a few years and
purchased a Canon 30D, which was an amazing workhorse both for
conventional and astronomy photography. I still have this camera after it
taking thousands of frames for me. I next purchased a Canon XTi
which was specially modified by Hutech Corporation in California to be more
sensitive to the infrared spectrum that is so common with emission nebulae with
my work in astrophotography. A quantum leap in technology by Canon
convinced me to purchase a Canon 50D dSLR, which is the current winner in
my eyes for offering the best features to meet my needs for conventional
photography. It is also an outstanding instrument for taking astronomy
photographs despite it not being modified to be more sensitive to infrared like
my XTi is.
Canon dSLRs are one of my main imaging sources
for my Astrophotographs.
Please refer to my Imaging
Hardware page for more details about how I acquire my
astronomy images.
Despite being firmly in the digital imaging camp, I still
have thousands of slides and other transparencies I want to digitize. I replaced the ScanMaker 35t+ film scanner
(with its rather limited resolution and dynamic range) with the
Nikon Super Coolscan 4000ED and quickly found new uses for my existing archive of film images.
 |
Dynamic Range of 4.2 -
means this scanner "sees" more of the subtle detail to be found in the film
emulsion.
This is especially apparent in deep shadows and highlights. The
14-bit A/D conversion input and 16-bit output is a primary
reason for this achievement, although obviously the lenses used, the LED
lighting, and other scanner subsystems all contribute to a superb result. |
 |
4,000 dpi maximum resolution
- I make use of this resolution for astronomical photos, but really don't
need this high resolution for photos of regular subject matter. I
purchased the scanner based on its Dynamic Range more than the high resolution. |
 |
Digital ICE3™
(cubed) - software technology (developed by Applied
Science Fiction Inc.), which improves the final results of
film scans in three ways:
 |
Digital ICE™ (Image Correction &
Enhancement) - this feature is simply awesome, and is almost
worth the premium price for this scanner all by itself. Using an infrared
scan built into the scanner hardware, this software detects any "dirt" (dust,
scratches, fingerprints, etc.) in the film being scanned, then masks them out of
the final image scan. This feature saves hours and hours of hand spotting
scanned images, or running complicated filters over images that are not always
successful. |
 |
Digital ROC™ (Reconstruction of Colour)
- again, quite amazing what this technology can do to restore faded colours from
old film, or correcting strange hues caused by underwater photography or
processing chemical stains. |
 |
Digital GEM™ (Grain Equalization &
Management) - I haven't made use of this technology very
much, but at high resolution scans, Digital GEM will "smooth" the results, since
individual grains of film are apparent at high resolutions. |
|
 |
SCANNER NIKKOR ED
high-resolution/high-performance lens - Nikon has a
well-deserved reputation for producing some of the best lenses for their cameras
as well as their scanners. This 7 element lens is specially-optimized for
high resolution scanning, and is key to the success of this scanner in dealing
with images other scanners simply give up on. |
 |
Scanning speed throughput
- when scanning at these high resolutions, it can take some scanners five
minutes or more to deliver an image to the computer. Nikon's claim that
this scanner will scan a full frame 35mm film in 38 seconds is very close to
what I am achieving. |
 |
Firewire Interface - this
interface to the computer is the fastest technology around, and is considerably
faster than either SCSI or USB1.x, both of which are used by other scanner
manufacturers. The 4000ED even comes with a Firewire (IEEE1394)
adapter and cable right in the box. |
So, now we're back to the darkroom...but a digital version this time:
