Project 3

The pictures taken for this project show the effects different apertures have on the depth of field, that is, the amount, from foreground to background of the picture that is sharp. This can be used to either ensure the whole of the scene is the object of the photograph, or that only a small portion of the photograph is important.

In a landscape, often the whole scene is to be captured, with no one element being of greater importance that the other, but take for instance a wedding photograph taken in front of a church. The important element will be the bride and groom, and the architecture of the church would only distract from this. Therefore, using a wide aperture, the bride and groom can be sharp whilst the background gently blurred.

In this instance care needs to be taken to ensure that the aperture is not too wide otherwise you may find that the brides nose is sharply focused whilst her ears are blurred!

The two pictures below show these effects, with the first being at f 2.8, and the second at f 22.

This image at f2.8,shows that the words in the centre are sharp whereas those in the foreground and background are not.

This image (f22) shows an almost evenness of sharpness from front to back.
