Apeture – One of the three pillars of photography, the others being the ISO and Shutter Speed, apeture is the opening of the lens through which light passes through in order to reflect/ enter the camera. This concept can be linked to how our eyes work, as your surrounding ight changes from datk to light, the iris in your eye either shrinks or dialates – controlling the size of your pupil. However, in photography the ‘pupil’ of your lens is apeture. The apeture of a photo can durastically change the overall exposure or, brightness of the image; if an image is over – exposed the lens is letting in too much light/ apeture too high.

Depth Of Field – The distance between the closest and furthest object in a photo that appears clear. For example, in a photo with a ‘narrow’ depth of field, only a small section of the image will be in focus/ clearly visible. Therefore, reversley, a photo with a large depth of field, will allow the overall image to be a lot clearer and sharper.
