11. • Pentax, similar to name brands Nikon and Canon, made it’s mark on the industry with the widely popular
K1000, produced from 1976 to 1997. The K1000's extraordinary longevity makes it a historically
significant camera, despite its very ordinary design. Although the K1000 was already obsolete when it was
first released, its inexpensive simplicity was a great virtue and earned it an unrivaled popularity as a basic
but sturdy workhorse, particularly suited to educating inexperienced photographers. The Pentax K1000
eventually sold over three million units, a milestone with in the industry.
12. Not only was the same camera made
for 20+ years
just about every k-mount Pentax lens ever made will work on a current Pentax
digital body. The same is true of most Nikon DLSRs. Canon changed the lens
mount when they introduced their Digital SRL.
13. Wide Variety
• Camera manufacturers
produce large variety of
lenses for a large variety of
reasons.
– wide angle,
– long telephoto
– macro
– Architecture
– fast primes
– all in one zooms
– And a bunch of variation
amount the above
14. • Popup flash…
good for 10-15’
• Red window for
wireless remote
Front View w/o Lens
15. Front Left View
• Shooting mode
dial on top
• Focus switch –
manual or auto
• Lens
• 18-55
• Close focus
capability
down to 1’
16. Zoom Lens – a tactile zoom…easy to go from
one end to the other end of the focal range.
17. Zoom Lens – But the lens lets in a lot less light
at the long end.
18.
19. Zoom Lens –
Is usually a compromise.
Cover lots of ranges, but
sacrifice quality.
20. Zoom Lens
If you don’t want to shoot commercially,
then the NEW Nikon 18-300 would be a fantastic lens.
21. Zoom vs Fixed Focal Length
18-300mm vs 50mm
Which sounds better?
Would knowing the price help?
18-300mm vs 50mm
$900 vs $125

This is one time paying
MORE is not
necessarily better.
Zooms frequently cost MORE
and are NOT as sharp,
but they are more convenient.
26. Connecting camera to the computer
• NEW!! Keep camera around your neck until you are at the
computer, then place on the blue mouse pad.
• Turn the camera on
• Type a windows Key + E.
27. San Disk, Secure Data (SD)
Ultra II Plus
• There is a LOCK to the left side of
the memory card.
• The lock broke, so I removed it, and
messed up the card. A piece of
JBWeld is in it’s place. Please don’t
pick at it.
• If your camera comes up saying that
it is locked, take the memory card
back out, flatten the tape, trying not
to lock the card upon insertion.
38. View Finder SLR, TTL – You are looking
THROUGH THE LENS of a
Single Lens Reflex.
Most CURRENT DLSR have a LIVE
preview, where you have to hold the
camera out in front of you. The k100d
CLASSROOM set does NOT have live
preview. The home camera DOES have a
live preview. It is useful, but not perfect,
drains the battery and result in lost shots.
USE THE VIEW FINDER…it is the
MAIN advantage of the rapid fire DSLR.
41. Main Features
• AutoISO
• Shake Reduction
• Depth of Field Preview (with live preview)
• 16-segment multi-pattern metering system
• Picture and Scene Modes "Auto Pict“, six programmed
picture modes for specific scenes: portrait, landscape,
macro, action, night scene portrait, and flash off. 8
additional scenes modes available: night scene, surf and
snow, text, sunset, kids, pet, candlelight, and museum.
42. 2-stage shutter release is
a shutter release, that when pressed
halfway, it activates the autofocus and
the light meter of the camera, setting
them to achieve correct focus and
exposure.
Holding the release at mid-
course maintains the focusing
point and allows for re-
composition if desired. A
further press on the shutter
release takes the picture.
*Think about when you’re focusing your camera. Whenever
you press the shutter down half way, it will automatically
focus on what you’re shooing (if auto focus is on). That’s
exactly what it is.
43. Main Features, Cont.
• Advanced 11-point autofocus mechanism…with 9 of those being
cross-type sensors (capable of detecting both vertical and
horizontal focus) the SAFOX VIII autofocus system on the K100D
Super uses nine cross-type sensors … meaning greater autofocus
accuracy
• Focus and Recompose – Move camera to center subject, hold the
shutter half way down to LOCK the Focus, keep holding shutter
down…and move camera back to recompose, then push shutter the
rest of the way.
Even state of the art cameras with
the BEST AF systems on the
planet still need a little help
getting the right thing in focus.
46. Let gravity work
for you!
• It’s not just a matter of
LOOKING like you
know what you are
doing, there is a reason
the left hand goes
UNDER the camera.
48. Camera Handling – WRONG WAY
• Placing your hand
around the TOP
of the lens is
about as stupid as
pointing your
flash
SIDEWAYS!
• The camera is
MUCH more
stable with your
left hand UNDER
the lens.
54. Camera # =
ROLL #
• Get your camera
– Hold on to the
lens, pull up by
strap
• Extra Batteries
• Memory card
55. Special & Unique Memory Cards
• Don’t force them to open, or be rough with
them. Most memory is EASILY replaced,
this is not.
56. Battery System
• Invert one battery in the
opposite direction
indicating a depleted set.

57. • Cameras have different ISO ranges:
Model/Time Frame ISO Max Useful
– Film in 1985 25-3200 200
– Film in 2004 100-3200 800
– Canon A85 (2004) 50-400 200
– Pentax *ist (2004) 100-1600 800
– Nikon D40 (2006) 200-1600 1600
– Pentax K100d (2006) 200-3200 1600
– Nikon D3 12/2007 100-25,000 6400
– Nikon D3s 12/2009 100-102,400 12,800
Camera manufactures will usually include a HIGH ISO that is not really useful except for really casual
stuff. This means that you can use it…but the results will be pretty noisy.
59. ISO: 200-3200 – Shoot at the lowest ISO possible to get sharp pictures
Auto ISO is the default setting for the auto and scene shooting modes and will set a sensitivity
between 200 and 3200 as it deems appropriate. You can also limit the auto ISO range to
whatever you choose, such as 200 to 800. ISO 200 is the default for the P, Tv, Av and M modes
unless you have previously selected an ISO. ISO may also be manually set at 200, 400, 800,
1600 or 3200.
60. Film Grain
• Ironically, today, there are companies
designing software to ADD grain to pictures
to simulate the film of yesterday.
TriX TMax Old film Old film Kodak Kodak
72. ISO 3200
• ISO200 and ISO400 both produce very
clean images, and even by ISO800 noise
levels are well controlled. Images taken at
ISO1600 have more noise present, but not
excessive amounts. Things start to get
messy at ISO3200, this sensitivity should
be reserved for when nothing else will do
as the level of noise will be clearly
noticeable, even in smaller 6x4inch prints.
73. K100d vs. Other Cameras…ISO
• The K100D performs well for its price point. Noise levels are
acceptable, being better than the Pentax-based Samsung GX-1S. The
Canon EOS 5D outclasses the Pentax, but then it should do, it costs
around three times the price of the Pentax.
74. So, why shoot at HI ISO?
• Because it’s 4x as sensitive…giving you 4
stops faster shutter speed.
– Example: If your BEST shutter speed in a dark
place, like a concert, is 1/15 of a second @ ISO
200…you would get:
• 1/30 at ISO 400
• 1/60 @ ISO 800
• 1/125 @ ISO 1600
• 1/250 @ ISO 3200…which is fast enough to stop
somebody who is jumping around on stage…or
flying through the air
79. AUTO PICT = Pickle Mode
• When you are in a
stressful situation, and
your pictures aren’t
turning out, put it on
Pickle Mode.
• All other times, use either
Av or M.
80. Shake Reduction
• PENTAX original Shake Reduction mechanism
for sharp, blur-free images
• Using magnetic force, this SLR system shifts the
camera’s image sensor vertically and horizontally at
the optimum speed to compensate for the amount of
camera shake detected, assuring outstanding
compensation effects (equivalent to approximately 2
to 3.5 shutter steps). Since this versatile system is
compatible with all existing PENTAX
interchangeable lenses*, it does not require special
anti-shake lenses equipped with add-on optics or
devices.
83. • PENTAX, Olympus and Sony (formally
Minolota) use camera based
– Advantage: ALL lenses used on the camera will benefit
from the reduction of camera movement
– Disadvantage: movement is greatest at the end of a
lens…so camera based is not as effective for long lens
stabilization.
• Nikon and Canon use lens based stabilization.
– Advantage: Image movement is the the most significant
at the end of the lens where stabilization is most
benefited.
– Disadvantage: Each lens has to have the costly
components driving up the cost.
Camera based vs. Lens based
84. Resolution
• Generally, shoot at the HIGHEST resolution possible.
• 4M, (better) is more than enough for class photos
86. Menu Button
• Press Menu, then arrow selection buttons to navigate. Use
right arrow to select. Use OK only when prompted.
87. Process of reducing size of digital files by changing the way the data
is coded (It does not involve a physical change in the way the data
itself is stored; there is no physical squeezing or squashing). *
Uncompressed data may be re-coded in a more space-efficient form
without any loss of original information (the compression is
'lossless') or it may be coded to lose specific parts of the data which
are considered less important than other parts (the compression is
'lossy'). *When you save a picture in Photoshop, a small box will pop up. Within that box,
there is a section for your image’s quality. This is choosing the images compression.
The lower the number, the worse the quality (the picture is more pixelated). This looks
worse, but it a way to say space. The higher the number, the better the quality, but this
could take up a lot of space.
88. Compressed graphic format standardized by the Joint Photographic Experts Group (JPEG).
This supports up to 24-bit color, which makes JPEG a good format for storing digital photos.
JPEG images are commonly used for Web graphics and for storing photos taken with digital
cameras. They are usually saved with a .JPG extension.
The term actually stands for "Joint Photographic Experts Group," because
that is the name of the committee that developed the format. But you don't
have to remember that because even computer nerds will think you're weird
if you mention what JPEG stands for. Instead, remember that a JPEG is a
compressed image file format. JPEG images are not limited to a certain
amount of color, like GIF images are. Therefore, the JPEG format is best
for compressing photographic images. So if you see a large, colorful
image on the Web, it is most likely a JPEG file.
89. Jaggies are stair-like lines that appear where there should be smooth straight lines
or curves. For example, when a nominally straight, un-aliased line steps across one pixel,
a dogleg occurs halfway through the line, where it crosses the threshold from one pixel to
the other.
*Jaggies can occur for a variety of reasons, the most common being that the output device
(display monitor or printer) does not have enough resolution to portray a smooth line. In
addition, jaggies often occur when a bit-mapped image is converted to a different resolution.
This is one of the advantages that vector graphics has over bit-mapped graphics – the output
looks the same regardless of the resolution of the output device
