Q1 – Detail two reasons why we change the ISO

We change the ISO so the image doesn't blur.

With ISO it will depend on what the lighting will be like. the better the light the lower the ISO, but if the lighting is bad like in a poorly lit classroom the ISO will have to be high 

faster shutter speed so increase ISO so you can capture and image quicke if your outside  and you want to take pictures of animals for example.

Q2 – Explain the difference in depth of field between a wide and a narrow apature

A wide appeture is shallow depth of field the smaller the hole the greater the distance 

A narrow apperture is used when you want the lens to focus on the foreground on a certain iteam and blur the background. 

Q3 – List four consideration your had to take into account when producing your pop-art photography. For example, depth of field, shadows etc).

 Wires so we don't trip or break anything. 

you don't want shadows

You need it to focus on the iteam and not anything else so you'll need to put it onto manual to adjust it.

low ISO gives quality and detail in an image.

Q4. Describe when would you choose to use the ‘A’ and the ‘P’ modes on a camera

A= Apperture- Controls the depth of field. if you open the apperture it helps quicken the ISO.

P=Program.
