depth of field

Depth of field means "Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph" according tohttp://www.mir.com.my/rb/photography/fototech/htmls/depth.html there are good photos here to show what it means.

http://www.cambridgeincolour.com/tutorials/depth-of-field.htm is a more complex site but it helps me learn how to do it and has more science bits.

this photo by Annie Liebowitz is very interesting. It has quite a short depth of field because it is shot in a room so the actual distance is only a few meters from the front object (the edge of the stage) to the objects at the back (the wall). However all of the shot is in focus - none is out of focus. This means that all of the image is clear. She is not making any out of focus to draw attention to other parts.Most of the image is in shades of grey too - I think it must be quite a challenge to use all similar colours and still make the audience look at the bits you want them to see.

My eye is drawn to the naked torso, it is a different colour to the rest of the image AND it is on the right of the shot, half-way down the page. This is a strong position to put the main subject. It means that even though the depth of field is quite short and the focus is even all over I see him first.

I think i might have been tempted to make the background out of focus so that both men are clear.
I found a video that explains it well
