effect of shutter speed

as you can see i have had the shutter speed at a long length so much light went through that you can see the image is unseeable 
          This was a photo that had the right shutter speed and can be seen clearly

 once again this photo is overexposed to the light making the image too bright to see this and the other bright photo at the top is because the shutter has been open too long allowing lots of light to get through
This image shows the photo naturally this is done by quick shutter speeds not allowing too much light to go through to the sensor

next time i take pictures i will make sure i include a under exposed image which is where the shutter speed is so short that no light at all is able to go in to the picture making for a very dark image the opposite of the brighter overexposed images.

same photo graphs different apertures/depth of field

  The first photo i took had a aperture of f 22 as you can see it is pretty clear and well focused and both the background and the main object are clear and you can see the little details 



This one had a aperture of f 16 it begins to have more focus and lighting the background is slightly blurred but still clear

this has a aperture of f 11 not much change but the lighting is beginning to change more darker and in the background you can see more detail thanks to the change in lighting

This has a aperture of f 8 there is more blur and focus on the background and is more brighter but still blurred
And finally this has a aperture of f 5.6 the pole is blurred and the background is brighter and more shadier the background has less focus making it more blurrier

To make a summary the bigger the aperture and the smaller the number the less depth of field and the smaller the aperture and bigger the number the more depth of field and the more in depth the background. As you can see this reads true with my photos as the quality changers as it goes on with more blur and detail in the background.

the british gas advert description



                                                 Details of a advert: british gas

The advert begins with upbeat music. They use a narrator with a rather common voice in order to represent the main customer base. He explains all the positives to the service letting you know why you should be with british gas. The visuals is meant to give off a light hearted visual to what the british gas workers do. Advert ends with song reaching its climax and the companies logo you see the logo throughout advert too. The advert itself is a animation focusing on the visuals rather than a detailed description of the service because most people already know what it is they do.
