and if you just want a quick run-down, DOF is depth of field. It means how much of the photo is in focus. With a long DOF, almost everything in the entire image is focused well. If the DOF is very shallow, as in most macro shots, the background will be so blurry that it's indiscernable. Things that affect DOF are aperture (the higher the number, the smaller the hole, the deeper the DOF), focal length (aka zoom, the longer the focal length, the shallower the DOF) and distance from the lens (the farther away, the more DOF). So for the most DOF, you want a tiny aperture, wide angle, and a subject that is far away, like a landscape shot. For the least DOF, use a wide aperture, get really close, i.e. macro, and zoom way in.

Hope that helps!

See this thread for an example of someone appearing to have a Depth of Field problem. The last post in the thread goes into DOF examples at different focal lengths and apertures, and has a link to an online Depth of Field calculator:

If you need more basic than those sites, suggest you hit this site which is a free online "book" on the basics of photography:

/tag for further use

Thanks all - DOF translates to "Tiefenschärfe" (german) and so I know that effect with blurring backgrounds and stuff.But never really cared that it is actually a "field" which is sharp... only wondering why some pics looked better than others.

And pictures from other (read more professional) photographers looked soo much better in most cases too. Ok - with that knowledge you can TRY for a wide DOF if you need or a narrow one... understood.

Since I mostly try to "catch the moment" rather than to compose my pics I doubt I'll have the time for DOF calculation. But some basics will be useful, I am sure.

Many thanks again.

Followed some links and read a bit. Yes. Photography. I knew it was there but as a busy father you sometimes forget what you know already. I forgot that GOOD photography needs time. I guess I can't ask for superb photos when I try to point'n shoot - thanks for the reminder.
