  • Let's take over the comfy seats!
  • Circle Of Confusion at 25 30 Espresso

    Why:

    Because we all need a morning cuppa.
    Because it will give us some time to chat about photography.
    Because we can get out and make photos afterwards if the 
    inspiration hits us!

    I am looking for this to also be a time for group members to add their input on future Meetups. If you have a suggestion or something you would like to add and will be unable to join in the Meetup, please make a comment below so you can have input too.

    With this being a weekly Meetup.

    For those who are not sure what a Circle Of Confusion is:

    Circle of Confusion – an out of focus object that is rendered as a blurry disc in a photograph.

    From The Camera by Ansel Adams ©1980 volume one of The New Ansel Adams Photography Series pages 49-50:

    The image of a “point” in the subject should be a “point” on the film. If the subject is not exactly in the plane of critical focus, however, this image becomes a small blurred disc, called a circle of confusion.* The size of any circle of confusion becomes smaller as the aperture is reduced, making the image appear sharper.

    *Even with the finest optics there is no such thing as a “point” image. The image of a true point is always a minute circle because of inevitable diffraction effects of the lens. However, a lens of fine definition gives a minuscule circle or disc which we accept as a “point.”

    In practical terms, every image is made up of circles of confusion with some being larger than others. Those that are very small appear in focus and those that are relatively large show up as out of focus discs.
