80. Near or Far



I didn't do much today, so I don't have much to say. At some point what I was watching on DVR ended and the television automatically flipped to Dora the Explorer. I watched it for a good 20 minutes before I realized.

Some how I feel the need to explain the photograph or at least write a story that goes along with it... but no good stories today. How about some technique? Depth of field in photography defines the range of focus in an image. Depth of field is controlled by the aperture... to a point. Typically when you focus on subject matter far from the camera (i.e. several meters away) there is a lot of depth of field in the image no matter what your aperture setting is. And the opposite in true when you focus on something very close to the camera - very little in the image is in focus.  To sum it up? If you take a picture of a rose about one foot away from the camera lens, the rose will be in focus and the background blurred. Alternatively, if you photograph a mountain range miles away, everything in the image will appear in focus. Even though you may not know anything about photography your brain knows how far an image is from the camera depending on the blur in the photograph.

This is the secret to why today's post looks like a photograph of miniature diorama. I used PhotoShop to add blur to an image that had none. Giving the illusion that things that were very far, are very near.
