1/2 Done

IMGP1471.JPG

I shot the first half of the DOF exercise on Friday. I used a zoom and a fixed lens. Just looking at the lens markings on the zoom confirm yesterday's post.

The second half requires either a portrait or a still life.

The reason we use either a portrait or still life is, because when the subject is closer than 8 times the focal length of the lens the relationship of f/g and b/g DOF changes.

The top image was made using the fixed 50 mm lens, which actually has an equivalent 35mm focal length of about 80mm

Here are the two lenses used, it's interesting to notice that, the Zoom lens made for the Digital camera, has a smaller spread of distances under 1 metre than the fixed lens.
