You’ve read a lot about Digital Cameras. Wayne Cosshall now looks closely at the pros and cons of “going
digital”... |
For many of us who already have a substantial investment in film cameras, an interest in digitally
manipulating our images entails a choice: keep our film cameras and scan; or get rid of it all and buy
a digital camera. This is not a clear cut decision.
News about digital cameras is everywhere. In fact there is so much of it that it now totally overshadows
any news about films or film cameras at most photography trade shows. Does this mean that film is dead?
Definitely not. As you will see in this article there are still very good reasons to shoot film, at least
for some people.
Film and Scanning - Pros and Cons
Film is a known product. Around for a very long time, the manufacturers are still improving it; making the
grain finer and the colour better. There is a wide selection of films, from the mainstream colour negative
films, through colour slide and monochrome films to specialised films, like those for infrared photography,
widely used by fine art photographers and scientific and forensic photographers.
Scanners are, in a way, the precursor to digital cameras. Available in two types of relevance here:
dedicated film scanners and multipurpose flatbed scanners. Flatbed scanners are multipurpose. All of
them can be used to scan photographic prints. This will not give an ideal result but is more than adequate
for many users. For example, the real estate agents whose computer systems I installed are very happy with
a simple flatbed scanner that scans their prints for use in producing simple property fliers and for
uploading to the Web site. Many flatbed scanners also now incorporate the ability to scan negatives and
slides. Film scanners do one thing only, scan your negatives and slides. They will do a better job than a
flatbed scanner will, but at the cost of a dedicated piece of hardware.
Film Pros
- Cameras are relatively low cost
- Vintage equipment can be used
- Film holds a lot of information
- Film can be very archival if stored properly
- Film processing (at least for negative films) is available everywhere when travelling
Film Cons
- Film costs money per roll
- Film must be processed
- Processing costs money
- Images are not available instantly
- Needs a second stage to get onto the computer
- Prone to dust and scratches
Scanning Pros
- Can produce a very high resolution digital file
- Can scan at different resolutions
- Can correct dust and scratches with the right scanner
- Enables you to get "old" images into the computer
Scanning Cons
- An extra piece of equipment is required
- Scanning can be very slow, especially at higher resolution or when scanning many images
- Dust and scratches will be a problem unless scanner can remove them
- Labour intensive
Digital Cameras - Pros and Cons
Digital cameras are clearly the future of photography. They offer instant access to the images, and instant
feedback as you are learning, or experimenting with some new technique. This is an often understated value
of digital cameras. They are great for learning about photography because you can check your results
immediately. As anyone involved in education will tell you, immediate feedback is very important in
encouraging willingness to experiment, the avoidance of bad habits and the growth in confidence.
However, a digital camera needs to be part of a whole system of equipment to get the most out of it. You
will require a computer, photo printer, CD burner to backup your photos, rechargeable batteries and their
recharger, memory cards and possibly a card reader, a camera bag, camera accessories to suit the type of
shooting you do, insurance and software. Basic versions of some of these things will come with the camera.
Depending on your shooting style and interests, you may need to buy more.
Digital Camera Pros
- Instant availability of images
- No running costs (assuming rechargeable batteries)
- Environmentally friendly (ignoring their manufacture)
- Some advantages for people with disabilities
Digital Camera Cons
- Will be replaced by a better model the day after you buy it
- Expensive to buy
- Need to be computer literate (to get the most out of it)
- Buying one is only the start of your purchasing
Decisions for Different Users
Given that there are pros and cons for both film and digital cameras, there is no one single answer that
is applicable to all users. So, let's examine the question from the perspectives of different types of
users.
Let's start with the total newcomer to photography. This user has no existing investment in camera equipment
and needs to maximise learning capacity. For such a user going the digital camera route offers the best bet.
With a camera in the 2 to 3 Mp range, they will get good results, a reasonable amount of control over the
camera to experiment with and not have to spend too much money.
Now for the family person who has used a point and shoot camera for many years and wishes to do some playing
around with images on their computer. These people could actually go either way. However, the one I would
suggest for best flexibility would be to buy a digital camera, within the 2 to 4 Mp range depending on
budget, and a cheap flatbed scanner so that they can also play with their existing images. A cheap scanner,
in the $130 to $170 range, will meet their needs of getting those old family snaps onto the computer. An
alternative here is the scanning facility offered by a multifunction scanner/printer/fax.
The amateur photographer is a much tricker proposition, as they vary so much. The gadget freak amateur
should buy a digital camera, because in reality they won't be happy without the latest toy anyway. The
serious amateur, with a good selection of existing equipment and a large library of rolls of film, should
probably buy the scanner. A dedicated film scanner will provide the serious amateur with very high-resolution
images without breaking the bank. They can continue to use the equipment they are already familiar with while
they come to grips with the computer, Photoshop (or other programs) and the scanner. Then, in several years
time, they should be in the position to make the switch to a good quality digital camera that will not
disappoint them. Of course, the serious amateur with lots of money to spend can also buy a digital camera
straight away. However, they actually might get more out of the process by learning the software manipulation
side first.
Now we come to the professional or tradesman who uses a camera to document their work. This could be a real
estate agent, a plastic surgeon or a builder, for example. Here it depends on the volume of images that they
take. If many images are taken that need to be in the digital domain, then a digital camera will be far more
efficient than scanning. For low volume situations, a flatbed scanner may be all they need, to capture the
odd image of examples of recent work to put on the Web site or in a brochure, for example. Note that in
situations where there is a requirement for the images as part of a legal process, as for plastic surgeons,
there are advantages in sticking with film, because you can demonstrate that the image has not been altered,
by producing the original negative or slide.
Conclusions
Scanners still have their place. Dedicated film scanners are great for people with a large existing library
of film images and who are seeking the highest possible quality from their images at a reasonable price.
Flatbed scanners are great for people who do not require the maximum in quality, especially if scanning
prints. It is surprising just how good the results can be from scanning with a flatbed.
Digital cameras, whilst clearly the way of the future, still have some disadvantages. These disadvantages
are gradually disappearing but remain at present. However, they are great if one can afford one that meets
your needs.
Having the choice is good.

Good flatbed scanners are made by HP,
Canon and Epson, who also provide scanners in their multifunction scanner/printer/fax devices. Pretty
well any model will do well scanning photographic prints. Remember that since the print was produced as
a second generation from the original, most prints cannot really support scans at higher than 600 dpi.
So if you need to scan prints almost any recent flatbed will do the job well. Personally, I like the
Canon LIDE scanners since they are very thin and also get their power from the USB cable, so there is
no additional power supply. That also makes them great to take out into the field with a laptop
computer.
For film scanning with a flatbed, you need a model specially designed for this. Good models are made
that can scan film from strips of 35 mm negatives and slides up to 4x5 sheet film. The top end of
these seems to be the Epson Perfection 2450 Photo, a 2400 x 4800 dpi scanner.
For dedicated film scanners there are a good number of models also. The best ones in my testing are
the Kodak RFS 3600, Canon FS4000U and the various Nikon models. The Kodak RFS 3600 is a 3600 dpi, 35
mm only film scanner that has the unique feature of being able, with no accessories, to scan a whole
36 to 40-exposure roll of 35 mm film automatically in one strip. It takes a long time but is a great
feature if you need to scan a lot of photos. For some reason Kodak seem to have forgotten they sell
this scanner, though it is still available. The Canon FS4000U is a 4000 dpi, 35 mm and APS film
scanner that also has the ability to optically remove dust and scratches as the film is scanned.
This scanner works very well, but most people prefer to use third-party scanner software rather
than Canon's drivers. Nikon make a number of models for scanning APS, 35 mm, medium format and
large format films. These are the most expensive scanners but do an excellent job. |
