By Chloe Prendeville

Exposure is the amount of light let into the camera when taking a photograph.

Overexposed Images.

Underexposed Images

Three different factors control the exposure within a camera, these factors are;

Aperture: The space in a camera which light enters.
Shutter Speed: How long or short the shutter is open before closing this could be from 1/400th of a second to 4 seconds
ISO: The sensitivity to light, this will also change he grain of the image

ISO stands for International Organization for Standardization, the ISO on the camera controls the sensitivity to light. Cameras iso range will differ higher end cameras will have better capabilities, some cameras can range to HI2 some only 1600, the higher the ISO will increase the grain but also the sensitivity to light.

Shutter speeds
Shutter speed is commonly known as the thing that controls the time of the exposure. It’s the time taken for the shutter to close.
Some examples:
1/30 1/60 1/125 1/250 1/640 1/1000 1/2000 1/4000

This is an example of a low shutter speed. This picture would have been a very long shutter speed. You know this is a long shutter speed because it has just picked p the lights from the cars and you can see that they are moving

This is an example of a high shutter speed. This picture was taken in 1/200. You know this is a fast shutter speed as you can see it has frozen the image

Examples of other people works
This an example of a long shutter speed. As you can see the train is blurred and the person in the foreground is in focus. In order to take this picture they would have needed to use a tri pod to avoid camera shake. I got this photo from:

Depth of Field

Depth of field determines in photography and cinematography how deep or shallow the focusing of the camera is
Shallow focusing blurs the foreground and background whilst leaving the subject in focus.
Deep focusing keeps as much of the shot as possible in focus.
Shallow Focus
Deep Focus

The things that determine DOF are:
Camera to subject distance

The things that determine DOF are:
Lense focal length
The shorter the Focal length the greater the optical power and generally wider the angle. Used in microscopes,
A longer focal lense means that there is a lower optical power . Used in telescopes.

Lenses Research by
Andrew Carpenter

There are a lot of different types of lenses and varied lengths. Each lens will have a different purpose, for example lenses with a length of over 135mm+ can be used for sports or wildlife where as a lens that has a shorter length than 21mm will be a super wide angle which can be used for architectural photograph. Lenses will also differ in minimum and maximum apertures this will influence the price. The aperture of the lens will not only have effect on the price but also the depth of field that it can produce in a photo, how shallow the depth of field will be, most lenses have a maximum f. stop between 4-5.6 although some may be higher some lower. In the two pictures below the camera had been placed at the same distance away from the flowers the first photo was taken from the smallest length of the lens the second photo was at the farthest range on the lens.


Focal Length Of Lenses
This was a photo that I found on the internet it shows the different focal lengths of a lens on the same subject from the same distance, he probably used more than one lens as not many zoom lenses range from 18-200mm but they are available.
Although I do not know who took this photo, it came from this site.,r:18,s:0,i:125&tx=36&ty=23


Student Name: Andrew Carpenter

1.1 Ground rules set for example posting work onto posterous on time.

1.2 We discussed with the group and I researched ISO and Lenses

2.1 Producing a powerpoint this is provided online and in a work book.

2.2 We spoke between the group about what we’ve done and suggestions we gave feedback on each others slides to make sure the power point was correct

2.3 We all worked as a team helping each other

3.1 We looked through each others work after finishing to review

3.2 I contributed to the group by researching ISO and Lenses

3.3 www: I think that we worked well as a team and were able to give constructive criticism to each other ebi: I think it would have worked better if we had made sure we were completely finished before printing the documents
