Pop Art - Memory Check

Q1 – Detail two reasons why we change the ISO

 1) To allow the detail to be high focus or blurred, dependant on shutter speed.

 2) To change the sensitivity of the camera, dependant on light levels

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

Depth of field in a narrow appature will mean a deeper depth of field, allowing the whole object to be in focus.

Depth of field in a wide appature will mean a shorter depth of field, allowing part of the object to be in focus, the remainder blurred.

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

You had to take into consideration shadows, because they may be difficult to remove so try keep them to a minimum. You can control your shadows through the position of the light to the product or add an overhead light to your side lights.

You had to take into consideration depth of field, because you want the whole object in focus. You can control this by having a narrow appature, dependant on your level of lights.

You had to take into consideration shutter speed, because you want your object to be crisp and not be blurred. You can control the blurriness by keeping your shutter speed open for a small amount of time so it doesn't fill with light.

You had to take into consideration the background, because you want a seemless background with no creases or any extra marks that may be difficult to remove when it comes to editing. You can control this by having a newly placed, clean, fresh sheet.
