blur

  • 1. A. Kinds of blur NOT disqualified by TTG

    Motion blur caused by movement of the subject and camera in relation to each other (motion blur is reigned in by the sasibe standard)

    • See also the guide to panning and camera shake

    Optically generated blur — that is, any softness of the rendering that is caused by lens/aperture/focus choices, including focus/bokeh blur

    • The optical blur allowance is reigned in by P7, which for example would prohibit the use of an excessively soft lens or of contratilt

  • 2. Kinds of blur that ARE disqualified by TTG

    All varieties of blur that are not caused by factors listed in #1 above.

    This disqualification includes:

    •     Any post-exposure blurring or softening, whether localized or general, whether focus-related, motion-related, or other

    •     Fokeh (non-optical bokeh blur, which is added when using the “portrait” modes on smartphones)

    • Blur caused by accessories mounted on the front of the lens

    • blur caused by zooming the lens during the exposure

    • motion blur not caused by movement in the relationship between camera and subject
