Ready for Digital Photography?
During a recent visit to the camera shop,
the salesman asked me if Id like to trade my 35 mm compact
for a Digital Camera (digicam). Of course Id have to pay the
difference in price. I passed frequent glances between my six-month-old
zoom compact and the shiny new digital camera on the shelf. The
price wasnt steep, and I wouldnt need to pay for rolls,
developing and printing ever again. But I decided to stick with
my 35mm camera. Im sure other Indian proconsumers
are faced with the same decision and shy away from digicams.
The truth is there are some issues that
manufacturers needed to address to make digicams commodity items
(like cell phones). Ill analyse these issues here and then
discuss how digicams are evolving to address these issues.
I think there are four or five factors
that need to be addressed if digital cameras and digital photography
are to take offpricing/features, ease of use, a simple way
to share and view pictures, and prints.

Pricing/features
Digicams must be affordable, and this is especially important in
a price sensitive market like ours. Sub Rs 10,000 cameras should
offer decent resolutions of 2 megapixels and above. Presently, entry-level
cameras costing around Rs 5,000 (or less) offer low resolutions.
These cameras do not come with optical zoom (which enthusiasts and
professionals consider important). However some models make up for
that by doubling as Webcams, and some can even shoot short video
clips.
I think a digicam in the range of Rs 6,000
to Rs 8,000 would be a popular choice especially if it offers a
resolution closer to 3 megapixels and had at least digital zoom.
Ease of use
There are people who shy away from electronics gadgets because they
perceive these to be too complicated to operate. Of course, if you
cant figure out how to sync your newly acquired handheld with
the PC, get your 12-year-old cousin or son to do it! But look at
whats happened with mobile phones. It seems everyone knows
how to operate one. Cell phone manufacturers (like Nokia) wanted
their phones to be easy to use, and so they designed simple and
intuitive interfaces. The basic menu system on Nokia phones for
instance, remains consistent across all models. So even if you change
your phone each year, but stick with the same manufacturer, youd
never have to spend too much time learning how to use the new phone.
Nokia calls that Human Technology.
Well, Id like to see digicam manufacturers
emulating Nokia. In fact they should agree on standards and have
a common basic interface for all digicams.
Sharing and viewing
pictures
After youve taken all those great vacation pictures, youd
want to show these to your friends and family at home. Here are
some ways of doing this.
Pictures can be viewed on the tiny LCD
screen behind the camera, or you can take print-outs. You can also
transfer those digital pictures to a PC, edit these using some software,
and then view them on the PC screen. If the PC has a CD writer,
you could burn photo CDs and mail these to your friends. Another
option is to publish these photos to a website (and exchange its
URL)or you could use photo exchange services on the Web (like
Yahoo Photos).
But wouldnt it be simpler if you
could just connect the digicam to the TV so that the family could
gather round in the living room and see your vacation pictures?
Some digital camera models do offer this feature.
Also, some high-end television sets now
incorporate a memory card or memory stick slot. So you can pop the
memory card out of the camera, insert it into the TVs slot
and view those pictures instantly.
For the vast majority of us who do not
own such TVs, an option is to use a memory card device that can
be connected to the TV.
SanDisk, a well known manufacturer of memory
for portable devices, offers a digital photo viewer that functions
like a memory card reader. This device can be directly connected
to a TV. It has slots for various types of memory card formats like
Compact Flash (Type I and Type II), SmartMedia, Memory Stick, SD,
and MMC.
Prints
In order for digital photography to become more acceptable (especially
among professionals), its important that printouts match the
quality of conventional prints (from film). Printer manufacturers
are well aware of this and have taken steps to ensure this.
One way to ensure this, is technology that
improves the way photos are printed. HP for instance has PhotoREt
technologya process of layering multiple drops of ink in each
dot to produce photo realistic printed output. This technology has
been incorporated into HPs Colorsmart driver software.
Camera manufactures also sell special photographic
paper for glossy prints. Some vendors claim that the inks used in
their photo printers are fade-resistant up to 70 years.
Conclusion
Digital cameras and printers are still evolving and the technology
continues to improve. Manufacturers realise that there are other
factors (other than just resolution) that go towards making a great
digital camera. In a year or two digital cameras will become more
affordable and easier to use. Then you can go ahead and show off
your digital photography skills!

Digital cameras employ either
or both zooming technologies. With Digital zoom, the camera
is programmed to take a portion of the captured optical image
and enlarge it from the center. Since image enlargement is
manipulated electronically, it results in low quality enlargement.
Professionals prefer Optical
zoom as the camera lenses give you a true zoom, without losing
image quality. Its like using a professional SLR camera
with a zoom lens.
Naturally, a camera with an Optical
zoom lens is more expensive. The higher the optical zoom (combined
with high resolution) the higher the price. You can get cameras
with up to 5x optical zoom and 3.3 megapixels for a price
just under $500.
As a general rule, try to purchase
a camera that has at least a 3X optical zoom. Use the digital
zoom for amateur photography, but dont expect the higher
quality you get with an optical zoom.
Optical zoom cameras use more
power, since they have to physically move lenses back and
forth (versus a non-moving Digital zoom camera).
