2. Aperture
The Aperture is an important control for
dimming or brightening photographs. The
Aperture controls the amount of focus that is
visible in a photograph; the lower the F number
(F stop) the clearer the picture will be. A
smaller Aperture creates a large depth of field
and all the sails are in acceptable (sharp)
Shallow Deep
A large Aperture e.g. F2, F4, creates a small or
shallow depth of field, throwing a background
out of focus or goes blurry; it makes the main
subject stand out.
3. Shutter speed
Shutter speed controls the length of time and it is measured in fractions of a
second.
Slow shutter speed:
1 second, 1/2 , ¼, 1/8th, 1/15th, 1/30th, 1/60th, 1/125th, 1/250th, 1/500th
If the shutter speed is open for too long, the picture will be over exposed because
of how much light that has been let in. however, if the shutter speed isn’t open
then he picture will be under exposed where there enough light to go through.

4. Focusing
Focus is to do with how great the picture looks, its also to do
with Aperture and Depth Of Field. Focusing is the light rays
from an object that hits a tinted window called the lens
coverage, this forms a good image on the focal plane. You can
manually focus on taking a picture and auto focus however,
auto focus sometimes doesn’t give the best picture.
5. ISO
In photography ISO measures the sensitivity of the image sensor. Higher ISO
settings are generally used in darker situations to get faster shutter speeds.
Sometimes its better to keep the camera in ‘auto mode’ because the camera
choose the appropriate ISO setting. When you choose a a specific ISO you’ll
see that the Aperture and shutter speed have been impacted and therefore
gives a better exposed picture/ shot.
6. File formats
The most common image file formats are JPG, TIF, PNG, GIF and RAW. The
two main ones are JPG and RAW, JPEG is a compression technique for color
images, but it can also be used to reduce sizes from its normal size. It is
sometimes more important to reduce the size of a picture. RAW on the
other hand has a white balance setting, but it can be adjusted to however
you want it to be. Shooting in a RAW format can give you the flexibility to fix
a picture with a few adjustments.
7. Camera modes
The camera modes are on a dial at the top of the camera. if you leave it in
auto mode, the camera will give the best judgment to select the shutter
speed, aperture, ISO etc. Manual modes give the photographer full control
over the camera. For example, the shutter speed or ISO can be changed but
sometimes manually it would give a good picture.
9. Photographs in media
This is a picture of a Top Gear magazine cover. This would
be aimed at men because top gear is more of a men’s
show, therefore they would be attracted to the type of
cars that are on the magazine. On the front cover is three
red cars and a yellow car, these are bright colors to attract
people to buy the magazine. This might be aimed at men
that are more into sports cars than everyday cars and who
might have a lot of money.
10. Photographs in media
This is a film cover called eight below. This
would be aimed at anybody that loves dogs.
Its more of an outdoors film because there is
snow, water and a red fluffy coat that Paul
Walker is wearing the cover.
