A logarithmic tone curve produces footage with extra-wide dynamic range and generous exposure latitude, for easy colour grading.
Shoot with Canon Log and use View Assist to preview how footage may appear after post processing on the camera's LCD screen.
With Canon Log set, the following will not work with movie shooting: Picture Style, Auto Lighting Optimizer, Highlight Tone Priority, Time-lapse Movies, and HDR movies.
When shooting with Canon Log, achieving focus with AF on a subject under low-light or with low contrast may become more difficult than in normal shooting.
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 colour grading of the shot movie.
When Canon Log is set, the colour gradation of the sky or white walls may not be reproduced correctly. Irregular colours, irregular exposure or noise may appear.
Movies can be shot with a computer installed with EOS Utility. However, EOS Utility cannot be used to set Canon Log. Use the camera to set Canon Log.
