Image Quality when Canon Log gamma is set
When Canon Log gamma is set, vertical noise stripes may appear in
movies depending on subject or shooting conditions. It is
recommended to shoot a few test movies and check before the
actual shooting.
Vertical noise stripes tend to appear when the subject is dark and flat
or [Peripheral illumin.] is set to [Enable]. This noise may also
appear when ISO speed is relatively low, such as at ISO 400.
Additionally, the noise may become more noticeable when
A:8/7 is set compared to when other movie-recording sizes are
selected.
When the noise is noticeable, it is recommended to set [Peripheral
illumin.] to [Disable], shoot in brighter exposure, and perform
brightness adjustment during color grading. Also, noise may be
decreased when you shoot at ISO speed lower than ISO 320 (even
though the dynamic range will be narrowed).
