An exercise in depth of field in relation to portrait photography.
Using the lock down technique take a picture of someone in the class,
make sure the focus is on their face, and if possible open up the aperture
as wide as possible, then take some shots.
An explanation of "depth of field"

Composition 2 (divisions of an area - The
golden mean rule, left to right rule, the directions subjects look
in.) further reading link
The direction in which a subject looks influences how the composition
works, in this example the figure on the right "bounces" the
onlookers gaze back to the figure on the left, who in turn focuses our
attention on her eyes and face.
To do anything (change, delete, filter etc... ) either a
part or all of an image one must firstly select the area

Using a digital camera section
Group pictures, a problem of resolution? If you need the details of peoples
faces your camera may not be able to capture such fine details. Always
set your resolution to as high as possible for group pictures. It might
be worth using a higher quality file format such as TIFF or RAW for important
If you use low resolution settings the individual faces may appear blocky
when you zoom in to look at them

Digital camera section
Managing pictures ( Making copies, creating
Be aware that some cameras allow you to create folders on
your memory card, you may also be able to make copies of pictures which
are set at a different resolution to the original. This is useful if you
are running out of storage space and need to take more pictures. Firstly
delete unwanted pictures, secondly lower the resolution of any pictures
you may take from then on during that session. - Check out other ways
to lower the amount of memory a picture takes up, settings such as quality
and compression will also have an effect - . If you're still lacking storage
space you might be able to use the copy function. If you do so, save the
new one at a much lower resolution. For instance you may have a picture
that doesn't need to be saved at high resolution - approx. 2400 x 1600
- so you make a copy which is 600 x 400 and then delete the original.
By doing this you'll have gained enough space to shoot 15 pictures at
600 x 400. A useful feature in emergency situations.
Putting a zoom feature to use
Firstly if your camera has a digital zoom avoid using that
feature. If it has both an optical and a digital one then try to only
use the optical one. A digital zoom is just an enlargement of a part of
the ccd chip that senses the image in your camera, you may as well crop
your image and enlarge it in photoshop than use a digital zoom.
If you have an optical zoom however it can be put to many
uses. The first one is to zoom in on things that are distant, but it can
also be put to less obvious uses. Firstly when wanting to take a close
up of someone's face you'll find that if you hold a camera too close it
will distort their features and will probably be hard to focus. Holding
things close to your eyes makes the things look bigger, the closer they
get the larger they look, we all know this - hopefully -. From your eye
to about a foot away you will see the most dramatic effect. Therefore
if you have a person's nose 7 inches away from a camera lens and their
eye is 8.5 inches away the nose will look disproportionately bigger than
it should in relation to the eye. The face may even look like a caricature.
If you want to overcome this then step away from your subject and frame
your picture around their face using your zoom, it'll be far less likely
to distort their features.
There is an area between around 3 foot and 1 foot from your
camera that many cameras find hard to focus on. If this happens move away
from your subject and use your zoom to get the close up you require.
When zooming less light comes in to the camera. The speed
of a lens denotes how much light it can let in, a faster lens will be
able to zoom in on subjects in darker situations than a slower lens. Remember
if you're not able to get enough light to take a picture try zooming out,
you might find more light comes through the lens.
If you take a picture using a flash you might find that
being close up to a subject washes out (over exposes) the image, if that's
likely to happen take a picture from further away using the zoom, that
way the luminosity caused by the flash won't be so intense.
For those of you who wish to get into photography in some
Does your camera have an interface for an add on flash device?
This will either be a plug in socket for a "flash cable" or
a slide on socket known as a "hot shoe". If you can add a flash
gun you'll find a bounce head one can allow flash photos to be taken with
a far more subtle effect.
Colour range select tool
This technique is particularly useful when you have an area
that's got lots of things in front of it, such as sky or a wall might
Sometimes you'll have an area, or multiple areas of a picture
that consist of a colour range. For example a sky is often of a similar
hue, so if you wanted to select the sky this feature might be useful.
Go to the "select" drop down menu and choose "Color range".
A window will appear. Choose the pipette with a plus sign next to it and
start clicking on the area you want to select in the picture. A black
and white image will show you what area will be included in the selection.
If too large or small an area gets selected adjust the fuzziness slider
and see if that has a positive effect. When the area you want to select
is shown in the preview window to have turned white click on "ok".
If you find extra selections outside of the area you want have also been
selected you can tidy up the selection by using the lasso or polygon or
rectangular marquee while holding down the ALT key to de-select those
areas. If certain areas within the area you want to select are not selected
use the selection tools while holding down the SHIFT key to get rid of
The "Replace Colour" function
Here's an orange house
Have a go at changing the colour of the house using the
replace colour tool. (Image > Adjustments > Replace colour)
If other areas of thepicture change colour too then either select the
area you want to use before using the replace colour function or lower
the fuzziness setting in the replace color options box.

Introduction to scanning images
Quick history of scanners
Mention hand held - including pen scanners -, drum and flat
bed - also pass through (such as fax machines) .
Mention different interfaces, different pass modes, speeds,
and extras such as slide / film negative functions, sheet feeders, expandable
"Resolution and bits". Interpolation
Uses. make a lst with the group of uses.
What is TWAIN
TWAIN is a widely-used program that lets you scan an image (using a
scanner) directly into the application (such as PhotoShop) where you
want to work with the image. Without TWAIN, you would have to close
an application that was open, open a special application to receive
the image, and then move the image to the application where you wanted
to work with it. The TWAIN driver runs between an application and the
scanner hardware. TWAIN usually comes as part of the software package
you get when you buy a scanner. It's also integrated into PhotoShop
and similar image manipulation programs.
The software was developed by a work group from major scanner manufacturers
and scanning software developers and is now an industry standard. In
several accounts, TWAIN was an acronym developed playfully from "technology
without an important name." However, the TWAIN Working Group says
that after the name chosen originally turned out to be already trademarked,
an 11th hour meeting of the group came up with TWAIN, deriving it from
the saying "Ne'er the twain shall meet," because the program
sits between the driver and the application. The name is not intended
to be an acronym.

Using the crop technique
Panoramic camera or special lens? No just a crop of the image below
The canvas size function in Photoshop allows you to make
more space around an image so you can insert images next to it.So for
example this technique can be used for panoramic images as you can see
