    Depth of Field, as we know, is how much is in acceptable focus in from of and behind the area we focused on. I think it would be a lot clearer if it was called Depth of Focus.

    Anyway - most people quickly understand that one way to control it is by selecting the appropriate aperture for the amount od "dof" that is desired.

    But, focal length used is also a factor.

    Here are two shots. Both taken with the Fuji 50-140mm F2.8.

    1. Taken at 50mm and F/2.8. Focused on the bell.

    2. For this one I've stepped back and zoomed in to 140mm, still at F/2.8, to get about the same amount of handlebar in. Two things you'll notice...
    • There is less background
    • There is less depth of field - there is slightly more blur to the background.
    • The objects in the background appear closer to the focus point. Look at the green crossbar.

    I knew this theme would be educational, well for me it is:thumbup:
  4. Two good examples, it also lowers the angle of view being further away.
  5. It's always good to learn :)
  6. Great illustration of a good lesson.

    Yes I agree. We’ll try it a different way for the next theme I think :)

    :thumbup:i have just commented on Hollanders DOF thread.
  12. This is really effective
  13. Its a bit dangerous just focusing on the booze :)
    I'm liking the oof background and foreground too.

    In most cases out of focus foregrounds don't work very well. But they can when using a shallow depth of field to isolate a subject :)
  16. I don't mind focussing on the booze....and thanks for the education as well.
