EYV - Part 2 - Exercises




PROJECT 1 - The Distorting Lens

EXERCISE 2.1 - Zooming




Focal length = 28 mm *1,6 = 44,8 mm

Focal length = 35 mm *1,6 = 56 mm

Focal length = 42 mm *1,6 = 67,2 mm

Focal length = 50 mm *1,6 = 80 mm

Focal length = 58 mm *1,6 = 92,8 mm

Focal length = 70 mm *1,6 = 112 mm

I took six shots, from focal length 44 mm until 112 mm. The camera was on a tripod, so that the viewpoint did not change. Going back and fort across the shots it is easy to verify that the angle of view changes: in this instance the door handle moves from almost the central position within the frame until the extreme left position, nearly desappearing. I was sitting behind the camera and my angle view clearly matched with the focal length of 35 mm full frame, so 56 mm on aps-c format, on the second shot.

EXERCISE 2.2 - Zooming

70 mm * 1,6 = 112 mm

28 mm * 1,6 = 44,8 mm

I took the first shot with a focal length of 112 mm, then I moved toward the subject and zoomed out until the minimum focal length, 44,8 mm. The picture behind, previously hidden by the subject's head, in the second shot begins to appear between the chest and the left arm of the subject, and the glasses on the doors, invisible in the first shot, appear in the second. So new elements appear in the frame, even if the subject appears to be the same. This is the effect of the change both in viewpoint and focal length. 

EXERCISE 2.3 - Perspective Distortion

8 mm * 1,6 = 12,8 mm

In the previous shot the combination of 12, 8 mm focal length (so very short) and low viewpoint creates an extreme perspective distortion, giving to the subject a overhanging look. Vertical lines converge and proportions are slightly changed, sens of depth and distance as well.

EXERCISE 2.4 - Depth of Field

f 2,8  53 mm * 1,6 = 84,8 mm

I used a medium telephoto lens, with focal length 84 mm, together with a wide aperture of 2,8, in order to keep the subject in focus and obtain a shallow depth of field with sea and rocks. In this way the subject emerges and keep all the attention, while the background keeps his role and does not distract attention. 

EXERCISE 2.5 - Focus

f 2.8 47 mm * 1,6 = 75,2 mm 

f 2.8 47 mm * 1,6 = 75,2 mm 

I took these shots keeping blocked  a wide aperture and medium focal length , in order to stress as much as possible the effect of shallow depth of field, leaving all the work to focus. I prefer the first shot, were the foreground is perfectly in focus and there is a nice blurred background.

95 mm  f 4.5

EXERCISE 2.7 - Depth of Field

35 mm  f 22



45 mm  f 14
