Setting the Canon Log
Canon Log is a gamma characteristic for post-production. It maximises the image sensor’s
characteristics and attains a wide dynamic range for movie shooting. It reduces loss of
shadow and highlights details, and the tonal information from the shadows to highlights
can be incorporated in the movie.
During post-production, a lookup table (LUT) can be applied to movies shot with Canon
Log. Download the LUT data from the Canon website www.canon.com/icpd.

Image Quality with Canon Log
●When Canon Log is set, horizontal 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. Note that noise may become more noticeable
especially when you apply strong contrast during color grading of the shot movie.
●When Canon Log is set, the color gradation of the sky or white walls may not be
reproduced correctly. Irregular colors, irregular exposure or noise may appear.
●When the noise is noticeable, it is recommended to set [Peripheral illumin.] under
[z1: Lens aberration correction] to [Disable], shoot in brighter exposure, and
perform brightness adjustment during color grading.

image displayed on the LCD monitor has low contrast and is somewhat dark compared
to when a Picture Style is set.

with a clear-viewing characteristic. This makes it easier to check the image details,
etc.

the card. (The movie will be recorded to the card with Canon Log characteristics.)
●With [View Assist.] set to [Off], the movie image is displayed with the Canon Log
characteristic on the camera’s LCD monitor or also in EOS Utility (EOS software).
●Even if [View Assist.] is set to [On], the HDMI output movie image will be output with
the Canon Log characteristic.
●If [View Assist.] is set to [On], a magnied display will also be displayed with the View
Assist.
