Title: The Future of Photography
1The Future of Photography
2What is traditional photography?
- Lens
- Light tight box
- Light sensitive material
Canon EF 100-400mm f/4.5-5.6L IS USM (1400)
Eos 1v Camera (no lens) (1500)
Color and Black and White Films
3LensLength(s), maximum aperture
- LensOne or more pieces of optical glass or
similar material designed to collect and focus
rays of light to form a sharp image on the film,
paper, or projection screen.
Sigma 70-300 F4.0-5.6 Macro Zoom Lens (190)
4LensLength(s), maximum aperture
- Higher quality lenses produce sharper images, and
have a broader or more extreme range of potential
apertures and lens length(s). - Higher quality lenses also have sophisticated
focusing, light gathering and even image
stabilizing functions.

5Light Tight Box
- Light tight box(aka camera) From the lens, the
image exposes the film through the shutter.
Eos 1v Camera (no lens) (1500)
6Light Tight Box
- High quality camera bodies have a broader range
of shutter speeds and capabilities. - The camera body can be made of plastic, steel,
aluminum, magnesium, or other materials. Light,
sturdy materials improve mobility and durability.
High quality bodies have seals to keep out light
and dust. - The body also houses any electronics needed for
power maintenance, metering, viewing, and a host
of other potential functions.

7What is traditional photography?
- Light sensitive materialfilm is the image
recording device.
Color and Black and White Films
8Light Sensitive MaterialFilm
- Film is composed of emulsions of light sensitive
crystals spread evenly on a roll (or sheet) of
celluloid. - High quality films often have very desirable
qualities. Richer colors, smoother graduations,
very little grain, extreme ISO values etc. - A large negative is much more likely to produce a
high quality large (gt 8x10) print than a small
one.
9What is the Future of photography?
- Lens
- Light tight box
- Light sensitive material

EOS-1DS Digital Camera 6999
CCD and CMOS Sensors
10What is the future of photography?
- LensLength(s), maximum aperture
- Lenses lens length typically enlarged x 1.3 to as
much as x 1.7 due to the difference in size
between the CCD and 35mm film (1.5 x 1)making
long telephoto images easier and wide angle shots
much more difficult to obtain.
Canon EF 100-400mm f/4.5-5.6L IS USM
(1400) This is a 170-680mm with an x 1.7
enlargement factor.
11LensLength(s), maximum aperture
- Except for the enlargement, lens use is identical
because 35mm lenses are used for digital image
capture. - Lenses are beginning to be designed specifically
for the digital format and CMOS chips are
appearing that match the 35mm format exactly
eliminating the lens adjustments.
Sigma 70-300 F4.0-5.6 Macro Zoom Lens
(190) This is a 119-510mm with an x 1.7
adjustment.
12What is the future of photography?
- Light tight box(aka camera) From the lens, the
image exposes the film through the shutter. - High quality camera bodies have a broader range
of capabilities similar in almost every way to
their traditional counterparts.
EOS-1DS Digital Camera 11 Megapixel Camera (6999)
13Light Tight Box
- Digital Cameras have the film built in (CCD or
CMOS). - Digital cameras also have built in viewing and
storage capabilities.

w/o lens)
14What is the future of photography?
- Light sensitive materialA CCD (charge-coupled
device) or CMOS (complementary metal oxide
semiconductor) panel is the image recording
device.
15What is the future of photography?
- Images are transferred to memory, usually a small
removable card. - High quality CCD or CMOS sensors often have very
desirable qualities. First and foremost, they
capture more individual pixels of information.
They also provide richer colors, smoother
graduations, very little noise, extreme ISO
values, etc. - A large sensor is more likely to produce a higher
quality large (8x10) print than a small one.
16What about printing the images?
- Getting the images from capture through printing
is where the real advantages of digital come in.
There are at least two or three steps involved. - image editing software
- scanning (if you cant shoot digitally)
- printing

Epson 2200 (699) Epson 2400 (199)
17What about printing the images?
- Photoshop is the tool of choice for digital image
editing. - Photoshop replicates darkroom techniques and
creates many new techniques that arent possible
to do in a traditional darkroom. - Photoshop also allows for easy tinkering on
images without costly printing.
18What about printing the images?
- Scanning a print or negative and printing the
digital scan is a common choice for photographers
wanting high quality digital images at a
relatively low cost.
Canon 8800 2400 dpi 199
Epson 3200 3200 dpi 399
19What about printing the images?
- A very high quality inkjet printer will cost
about 100 (not including ink and paper costs)
but it will print beautiful full-color,
full-bleed photo-quality 8x10 images. - For about 350 you can print at sizes up to 13 x
44 - Print images directly onto printable CDs for
about 350.

20Future of photography pros
- Pros
- There are no film costs and no developing costs
- You can get instant feedback from a monitor on a
digital camera - Digital transfer allows for almost instant
exchange of images to anywhere in the world
(including your home computer) - High quality image manipulation tools like
Photoshop make many difficult darkroom tasks very
easy - Printers and scanners -- cheaper and easier to
use than darkrooms
21Future of photography cons
- Cons
- Formats change much more rapidly than film
formats making potential image or equipment loss
higher - Cost for digital image qualities and equipment
durability approaching professional 35mm
equipment are 2-3 times as high - Digital transfers and digital files in general
encourage the removal or loss of old, mundane, or
bad photos - Digital images are typically archived much less
thoroughly and permanently
