For these photos I used a low F number of 4.6 to produce a shallow depth of field; when only the foreground of the photo is in focus. I used an ISO of 540 and 460 with the below pictures due to the lack of natural light and the string of LEDs.

For the, below, photo the aperture was set at F.5, this allowed for a shallow depth of field to focus on the glasses frame, not the reflection in the lenses. Due to the darkness of the surroundings and the bright LEDs the ISO was set to 540. The resolution and quality of this image is not the best as the edge of the glasses are slightly grainy.

The aperture of this photo (below) was F.4.5, with an ISO of 200 and a low shutter speed. The low F stop allowed for a short focal length which created a shallow depth of field by blurring the background. This is because more light is allowed in. I used manual focusing for this picture, using the view finder to see when the object was in focus.Comparing the above picture to the below ones the quality of the pictures are vastly different. The below picture was taken using an iPhone camera. Using an iPhone camera has limitations when creating a shallow depth of field as the ISO, aperture and shutter speed cannot be changed and are pre-set. Also the image is very grainy with bad resolution.

The following photos demonstrate a deep depth of field using a high F stop.

This photo (above) used an F Stop number of 16, a shutter speed of 1/8 and a ISO of 200. The large aperture allowed for the whole photo to be in focus with a deep depth of field; when the foreground and the background is in focus. This is because less light is able to enter to the sensor so there is less information for the camera to process into an image. Also, I set the white balance to the cloud symbol due to the sky being very cloudy causing an excess of shade. However, the shutter speed should have been longer to allow move light in as the photo is underexposed; this is the same for the photos below.

The above photos used F Stop of 18, a shutter speed of 1/8, and an ISO of 400. All of the objects in these photos are equally focused, showcasing a wide aperture. I like these photos as the bright pink of the flowers contrasts against the dull shades of the background.
