Task two; technical

Aperture:

I looked at aperture and decided to take a photograph with an object in the far background to concentrate on. Here you can see that I have focused on the table  I am taking the photo from and they key blurred out thing that we notice in the background is the yellow safety sign. I chose this as I thought that the bold colour stood out in the image well as all the other colours in my photo and very mute and earthy colours.
I used a narrow and a wide aperture of f3.5 and f22. The photo I took with a narrow aperture is very blurred in the background and the focus is on the middle ground. On the other hand the photo with a high aperture is very focused on the background making the hazard sign very clear.
Low aperture would most usually be seen in either fashion photography or advertising. The background would be blurred out to bring all the focus and attention on the main object or feature in the foreground of the image.
A high aperture would be used during landscape photography to make sure everything in the image is clear and level with all the details in the photo in focus.

ISO:

The picture to the right at the top shows a photograph from underneath a chair.  Due to the high ISO we can see that the photo is overexposed letting a lot of light into the lens making the image look washed out and colourless. The image is unclear and makes it difficult to see what the photo is of. The photograph underneath it is from the same place with a lower ISO as you can see the image is more clear and has colour to it.
The top image is very overexposed and too light to see the picture clearly, this was taken with the ISO of 6400. The image below shows the photo from the same place and angle however the ISO is set to 800 making the image clear to see.

Colour:

The three pictures to the left show me experimenting with colour by changing the white balance, the photographs are from the same angle of the same scene however none of them are set to the same white balance. The image at the top is taken with the "shade" setting of white balance this gives the image an orange tone to it, the image below it was taken with a white balance set to "tungsten light" as you can see from the image this gives the photo a strong blue tint to the picture, the image below is set to a white balance called "white fluorescent light" this also gives a blue tint to the picture however not as strong as the setting above. The lowest image is more purple toned than blue.

Taken with a high shutter speed of 1-500

 Shutter speed: 

Taken with a low shutter speed of 1-40

When looking into shutter speed I did some primary research using both a low shutter speed of 1-40 and a high shutter speed of 1-500 to see the difference. As you can see from the images to the right, the top image is a lot clearer than the image below and captures the movement of the person jumping from some stairs, the lower image is very blurred and doesn't have much detail to the person in the image. This is evidence that the higher your shutter speed the clearer the image will be and the movement will be captured better. Changing the shutter speed will help you to take a moving image the way that you want to for example if you were to take an image of a water droplet falling you could either use a low shutter speed to get a smooth photo of the droplet falling or you could use a high shutter speed to capture the drop almost as if it was still so you can see all the details in the photo.









composition:
This image shows The Rule Of Thirds The rule of thirds is a guideline often used when taking photos, it is when you add imaginary lines both horizontally and vertically to make 6 equal boxes to help you put the most important parts of the photo where the lines intersect.

As you can see in this image, the rule of thirds grid has been placed over the photograph so that you can clearly see how it helps when taking a photo. This is a very good example of the way the rule of thirds helps to make an image look good. This image here is a landscape image of a sunset at sea, as you can see the lowest horizontal line is parallel to the furthest part of the sea and also is in line with the sun perfectly, thanks to the sun being in line with the last horizontal line this means that the middle box is now filled with the centre of the clouds and warmest colours, this pulls all the attention to the centre of the image and makes the image have more depth and warmth. Both of the 2 boxes at the top left and right show a darker cloud running across the top of the image, the placement of the darker clouds are almost equal and both of the bottom left and right boxes have a rowing boat in them, again this draws more attention to the centre of the image due to it being equal elsewhere in the photo.

The image underneath shows my attempt at showing composition. I took a photo of a class member sat on a chair in the centre of the image. I used the grid over the image to make it obvious that he is central in the image, the horizontal lines go equally through his knees and half way between his elbow and shoulder. The top horizontal line is perfectly in line with the neck hole of his top . The 2 vertical lines also go through his knees and all of the lines when crossed in a grid formation split the image into 9 boxes. The boxes that pull in the most attention are the middle box and the middle top box, the top middle book has an equal shot of his head and shoulders. Also the middle box shows his body, this again is very equal and central with an equal amount of space surrounding his body.
