Parallax Error
Parallax is an apparent displacement or
difference of orientation of an object
viewed along two different lines of sight, and is measured by the angle
or semi-angle of
inclination between those two lines
Digital single-lens reflex camera.
http://en.wikipedia.org/wiki/Digital_single-lens_reflex_camera
A digital
single-lens reflex camera
(digital SLR or DSLR) is a digital camera that uses
a mechanical mirror system and pentaprism to direct light from the lens to an optical
viewfinder on the back of the camera.

F-number
http://en.wikipedia.org/wiki/F_stop
In optics, the f-number
(sometimes called focal
ratio, f-ratio, or relative aperture[1]) of an optical system expresses
the diameter of the entrance pupil in terms of the focal length of the lens; in simpler terms,
the f-number is the focal length divided by the "effective" aperture
diameter.
It is a dimensionless
number that is
a quantitative measure of lens speed,
an important concept in photography.
Depth of field
http://en.wikipedia.org/wiki/Depth_of_Field
In optics, particularly as it relates
to film and photography, the depth of field (DOF) is the portion of a scene
that appears sharp
in the image. Although a lens can precisely focus at only one
distance, the decrease in
sharpness is gradual on either side of the focused distance, so that
within the DOF, the
unsharpness is imperceptible under normal viewing conditions.
NB.These pictures are also courtesy of Wikipedia
F22 = Very deep field
F2.8 Very shallow field
At f/32,
the background is distracting.
At f/5.6,
the flowers are isolated from the background.
Metering mode
http://en.wikipedia.org/wiki/Metering_mode
In photography,
the metering
mode refers to
the way in which a
camera determines the exposure.
Exposure compensation
http://en.wikipedia.org/wiki/Exposure_compensation
Exposure compensation
is a technique for adjusting the exposure indicated by a photographic
exposure
meter, in
consideration of factors that may cause the indicated exposure to
result in
a less-than-optimal image. Factors considered may include unusual
lighting distribution,
variations within a camera system, filters, non-standard processing,
or intended underexposure or overexposure. Cinematographers may also
apply exposure
compensation for changes in shutter
angle or film speed, among other factors.

Term 4 Session 3: Factors When Buying a Digital Camera.
(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)
Remember when your looking at a digital camera it's a lot more than just the megapixels.
Major factors to look at are the lens, processor, software (firmware), build quality, brand reputation. For more factors check out this link to my reference site:
http://home.people.net.au/~james.bell/J01_photoref.html#S03
this has more links about this topic below the mind map.
Please report any links you may find, that don't work, to me so I can fix them.
This article seems worth reading........
Factors to Consider when Choosing a Digital SLR Camera
http://photo.net/equipment/choosing-a-dslr-camera/ <== follow this link for more.
"The newcomer to the world of Digital SLR cameras is presented with a bewildering array of options. It’s hard to keep track of exactly who is currently making DSLRs and how many models each have, but as of summer 2008 there were at least 9 manufacturers (Canon, Fuji, Leica, Nikon, Olympus, Panasonic, Pentax, Samsung and Sony) and between them there were something like 34 different models.
How do you choose which one to buy, and in what ways are they different? With so many different cameras available and new models being announced every few months it’s not really possible to make specific recommendations on which one is "best". The term "best" will depend on many factors unique to the user. However, I will attempt to outline the various factors that you might want to take into account when deciding which one to purchase."
Digital Zoom
This is the DP Review link about Digital Zoom really worth the look
http://www.dpreview.com/learn/?/Glossary/Digital_Imaging/Digital_zoom_01.htm
It's clear from the picture that digital zoom is not helping at all.
It's no clearer ... just bigger and your computer can do that!
----------------------------------------------------------------------------------------------------------------------------------
White Balance
http://www.dpreview.com/learn/?/Glossary/Digital_Imaging/White_Balance_01.htm
"Most digital cameras also allow you to choose a white balance manually,
typically sunlight, cloudy, fluorescent, incandescent etc. Prosumer and
SLR digital cameras allow you to define your own white balance
reference. Before making the actual shot, you can focus at an area in
the scene which should be white or neutral gray, or at a white or gray
target card. The camera will then use this reference when making the
actual shot."

1)The auto white balance was unable to find a white reference, resulting in dull and artificial colors.
2)The auto white balance got it right this time in a very similar scene
because it could use the clouds as its white reference.

Term 4 Session 2: Megapixels & Digital Colour
(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)
Relative size of the various megapixel images. Note that the 5 megapixel image is about
four times the size of the 1.3Megapixel image but that the 5 megapixel image is nowhere near
twice the size of the 3.3 Megapixel image.
If you have a 1.3 megapixel camera that take a top image size of 1280 x 960 pixels...
divide by 300; 1280 divided by 300= 4.26, and 960 divided by 300= 3.2.
So technically, that 1.3 megapixel camera can produce a
"photo quality" photo at 300ppi of 4.26 by 3.2 inches.
A 2.1 megapixel camera will generally produce an image around 1600 x 1200 pixels in size.
(1600 divided by 300 is 5.3 and 1200 divided by 300 is 4 ....
so a 1600 x 1200 makes a 5.3" x 4" 300 dpi print)
A 3.3 megapixel camera will generally produce an image around 2048 x 1536
A 5 megapixel camera will give you an image size in the neighborhood of 2560 x 1920 pixels
(2560 divided by 300 is 8.5 and 1920 divided by 300 is 6.4 ....
so a 2560 x 1920 makes a 8.5" x 6.4" 300 dpi print)

Term 4 Session 1 Card Readers, Resolution
(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)
Sections in ITALICS are copied directly from the web site at the link above them. ie. click on
the link to read the full article and find more information.
A USB Card Reader
http://en.wikipedia.org/wiki/Photograph
"Non-digital photographs are produced with a two-step chemical process. In the two-step process the light-sensitive film captures a negative image (colors and lights/darks are inverted). To produce a positive image, the negative is most commonly transferred ('printed') onto photographic paper. Printing the negative onto transparent film stock is used to manufacture motion picture films."
digital photography
"The advent of the microcomputer and digital photography has led to the rise of digital prints. These prints are created from stored graphic formats such as JPEG, TIFF, and RAW. The types of printers used include inkjet printers, dye-sublimation printer, laser printers, and thermal printers. Inkjet prints are sometimes given the coined name "Giclée"."
"Digital photography is a form of photography that utilizes digital technology to make digital images of subjects. Until the advent of digital technology, photography used photographic film to create images which could be made visible by photographic processing. Digital images can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
The main difference between the digital and analog is that digital must have a certain number of
steps or gradations but an analog representation has an infinitely fine number of steps and as such
should be able to produce a finer gradation.
As an example in a digital vs analog photo containing the sun the digital print will usually just be
smooth white but the analog may show some detail.
http://en.wikipedia.org/wiki/Pixel
"In digital imaging, a pixel (picture element[1]) is the smallest piece of information in an image.
Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using
dots, squares, or rectangles. Each pixel is a sample of an original image, where more samples
typically provide a more accurate representation of the original. The intensity of each pixel is
variable; in color systems, each pixel has typically three or four components such as
red, green, and blue, or cyan, magenta, yellow, and black."
"This example shows an image with a portion greatly enlarged, in which the individual
pixels are rendered as little squares and can easily be seen."
"A photograph of sub-pixel display elements on a laptop's LCD screen"
That is to say the red, green and blue bar work together to make one pixel
"A pixel does not need to be rendered as a small square. This image shows alternative
ways of reconstructing an image from a set of pixel values, using dots, lines, or smooth filtering."

(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)
To get the most out of using Picasa you can sign up for Google ... simply go to
https://www.google.com/accounts/NewAccount
and you can create an account .. try signing up with a user name made up by combining:
" your name" + "of" + "your suburb" (eg. bellfamilyofbelmont) it's easy to remember and
easy to explain to people .. that's where "picasaweb.google.com/bellfamilyofbelmont"
comes from.
Once you have your account It's not too much trouble to use Picasa to upload to the internet.
Remember you really only want to put up pictures that you don't mind
others looking at because the internet is, after all, a public place.
That said Google does allow you to set levels of permissions on the photo's

Importing Basics: About the Picasa Media Detector
Print
The Picasa Media Detector alerts you that new photos are available for import when you connect your camera to your computer using USB, place a memory card in a card reader, or place a photo CD in your CD ROM device. The Media Detector appears as a small Picasa icon in the Windows System Tray (the area with small icons directly next to where Windows displays the Time), and it launches automatically when you start Windows. Windows XP has its own media detection process, so in most cases you will not need to run the Picasa Picture Manager in XP.

Term 3 Session 5 Exposure Value, Rule of Thirds, Software, "Stop Motion" vs "Motion Blurred"
(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)
Exposure Value
In photography, exposure value (EV) denotes all combinations of camera shutter speed and relative aperture that give the same exposure.
Exposure Compensation is a feature of a camera that allows you to adjust the exposure measured by its light meter. Usually, the range of adjustment goes from +2 to -2 EV in 1/3 steps.
This means that you can adjust the exposure measured by the light meter by telling the camera to allow more light in (positive exposure compensation) or to allow less light in (negative exposure compensation).

This day was extremely overcast so the overexposed picture (dark one) still
does not have a lot of sky detail.
Once again a cloudy overcast day .. but at least I was there!!!

Fantastic shot!
Motion in a scene can be frozen or blurred depending on the shutter speed and other factors. Blur can be used creatively to evoke a feeling of motion as in this shot of a waterfall in Yosemite National Park.
This program works quite well and is completely free ...
... if you like the way it works you could ... if you wanted to ... pay for the full version ...
... most people I know have not bothered and I've not heard of any problems ...
... this is the antivirus I use myself.

Rule of thirds
The rule of thirds is a compositional rule of thumb in photography and other visual arts such as painting and design.[1] The rule states that an image can be divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines. The four points formed by the intersections of these lines can be used to align features in the photograph. Proponents of this technique claim that aligning a photograph with these points creates more tension, energy and interest in the photo than simply centering the feature would. http://en.wikipedia.org/wiki/Rule_of_thirds
