Exercise 2.6 and 2.7

These are a series of photographs I took as an example of how the depth of field, the f-stop setting, alters the focus of a photograph.  In the first one the f-stop was set at 1.8, and the focus was on the central beer can.  The last was one was set at 22, which means that the depth of field was greater and all cans are in focus.  The f-stop setting for each one is below the photograph.

Exercise 2.5

I took two photographs of these Playmobile characters standing on a log. In the first one I focused on the face of the one on the right.  The f-stop was 5.6 so the dof was very shallow, even the character on the left is slightly out of focus. The second photograph was taken with the focus on infinity.

Both photographs were set as follows:  f-stop 5.6, shutter 1/125 sec, ISO 200, focal length 80mm.

These examples show how the eye is drawn to the focus area, in particular to the face on the right hand character.  However, when looking at the right hand photograph the two characters are almost non existant, as the eye tends to ignore them.

Exercise 2.4

Same face, different lenses!  These photographs were taken with three different lenses, and the camera set to aperture priority.  These examples show that a standard 55mm prime lens is preferable for portrait photographs.  The model really does look like the second photograph.

  1. 1/50 sec. f/5.6 232 mm zoom lens
  2. 1/60 sec. f/5.6 55 mm standard prime lens
  3. 1/80 sec. f/5.6 18 mm wide angle lens

Exercise 2.3

These photographs were created by putting the camera very low down, shortest focal point, and focusing on the rock.  The result was a flat and distorted appearance.  The trees in the background were further away than they appeared in the photos, and not so bowed.  There is a slight incline in the land to the left of the rock, but not as much as appears in these photos.

Exercise 2.2

This exercise was intriguing.  I used a statue of an urn as my “person”, and was surprised what changed in the background.  How could the additional detail appear?  I wasn’t aware of the object to the left of the urn when I was taking the pictures!

 

Camera settings: apperture priority for both pictures.

  1. 1/200 sec. f/11 53 mm
  2. 1/200 sec. f/11 43 mm

Exercise 2.1

I found this exercise fairly straight forward, as it was just a case of taking a series of photographs standing in the same position with the same viewpoint, and altering the focal lengths.  However, the results were surprising.  I think the first picture was closest to my own view of the building.  I expected the second one to be the case, but it cut out some of the foreground detail.  The camera was set on aperture priority.

The camera settings for these 3 pictures was as follows:

  1. 1/80 sec. f/11 24 mm
  2. 1/80 sec. f/11 70 mm
  3. 1/80 sec. f/11 105 mm

.

The camera settings for these 3 pictures was as follows :

  1. 1/80 sec. f/11 24 mm
  2. 1/100 sec. f/11 75 mm
  3. 1/80 sec. f/11 105 mm

It was interesting that although I thought the viewpoint hadn’t  changed in the second picture, the shutter speed increased to 1/100 of a second.  I think I may have moved the camera for that shot, focusing on a slightly lighter area of the background so the camera compensated for that extra light.
